After initializing your repository, you can add new files, create directories, or upload existing files directly through the GitLab interface. This is a great way to start populating your project with the necessary components.
Remember to commit your changes as you go. Each commit serves as a checkpoint that you can revert to if needed. It’s also a good practice to include meaningful commit messages to document the history of your project.
Configuring GitLab Repository on Your Machine
Cloning the GitLab Repository to Your Local Machine
Once you have set up your GitLab repository, the next step is to bring a copy of this repository to your local machine. This process is known as cloning. Cloning creates a local working copy of your project, which you can then modify without affecting the central repository on GitLab.
To clone a repository, you’ll need the repository’s URL. You can find this URL in your GitLab project under the ‘Clone’ button. Here’s a simple step-by-step guide to clone your GitLab repository:
- Open Git Bash or your preferred terminal.
- Navigate to the directory where you want your project to be located.
- Use the
git clone
command followed by the repository URL.
For example:
git clone https://your-gitlab-server.com/your-repository.git
Ensure that the directory path you choose is the one where you want your local Git project to be created. After entering the command, your local copy will be created in the specified directory.
If you encounter any issues, verify that you have the correct repository URL and that your network settings allow access to the GitLab server. For instance, you might need to enter the base URL for your GitLab server plus the context path that points to your repository.
Setting Up Remote Repositories
Once you have your local GitLab repository initialized, the next step is to set up remote repositories to enable synchronization between your local and remote codebases. Configuring your remote repository is crucial for collaboration and maintaining a central source of truth for your project’s code.
To connect your local repository to the remote GitLab server, you’ll need the repository’s URL. This URL is the pathway for all the git commands that interact with the remote repository, such as git push
and git pull
. Here’s a simple guide to get you started:
- Obtain the URL of your GitLab repository from the repository’s page on GitLab.
- Open Git Bash and navigate to your local repository’s directory.
- Use the command
git remote add origin YOUR_REPOSITORY_URL
to establish a link to the remote repository. - Verify the connection using
git remote -v
, which should list the fetch and push URLs for ‘origin’.
Ensure that your local and remote branches are correctly mapped for seamless collaboration. For example, if you’re working on the ‘master’ branch, you would use the command [git pull origin master -u](https://www.geeksforgeeks.org/setup-gitlab-repository-windows-10/) to synchronize your local repository with the remote one.
Remember to replace YOUR_REPOSITORY_URL
with the actual URL of your GitLab repository. If you encounter any issues, refer to the troubleshooting section or consult the GitLab documentation for advanced server settings.
Pushing and Pulling Changes
Once you’ve set up your local repository, you’ll need to synchronize your work with GitLab. Pushing changes to GitLab is straightforward. Start by committing your changes locally with git commit
. Then, push your commits to the remote repository using git push
. If you’re working on a feature branch, ensure you push to the correct branch with git push origin <branch-name>
.
To incorporate changes from GitLab into your local repository, use the git pull
command. This merges updates from the remote branch into your current branch. It’s a good practice to pull changes regularly to stay in sync with the team’s progress.
To push and pull between your existing project and GitLab, you must issue a [git remote add](https://www.theserverside.com/blog/Coffee-Talk-Java-News-Stories-and-Opinions/How-to-add-and-push-an-existing-project-to-GitLab)
command. This provides your local Git repo with the GitLab URL which is essential for the synchronization process.
Ensure your local and remote branches are correctly mapped to avoid conflicts. Regularly fetching and merging changes can help prevent significant merge conflicts later on.
Leveraging GitLab’s CI/CD Pipelines
Understanding the Basics of CI/CD
Continuous Integration and Continuous Deployment, commonly known as CI/CD, are fundamental DevOps practices that automate the stages of software delivery. The automation of these processes ensures that code changes are integrated, tested, and deployed efficiently and reliably.
To set up CI/CD pipelines in GitLab, you start by creating a .gitlab-ci.yml
file in your project’s repository. This file defines the pipeline’s structure, including stages for building, testing, and deploying your application. Here’s a simple breakdown of the key components:
- Stages: Logical phases of the pipeline, such as build, test, and deploy.
- Jobs: Tasks that run during a stage. Each job is defined by a script.
- Scripts: Commands that execute the job’s actions.
- GitLab Runner: The open-source agent that runs your jobs.
By optimizing your pipeline, you can reduce build times and improve resource utilization, leading to a more efficient development cycle.
Understanding the CI/CD pipeline’s flow and how to edit it using the Pipeline Editor or integrate third-party tools can greatly enhance your project’s productivity. Regularly reviewing and maintaining your pipeline ensures it remains effective and up-to-date with the latest practices.
Creating Your First Pipeline
To set up your first CI/CD pipeline in GitLab, you’ll need to create a .gitlab-ci.yml
file in the root directory of your project. This file defines the pipeline configuration, including stages for building, testing, and deploying your application. Start by specifying the stages of your pipeline, such as build
, test
, and deploy
. Each stage contains jobs that run scripts to perform necessary actions.
For each job, you can define specific commands or scripts that should be executed. Here’s a simple example of a job within the test
stage:
stages:
- test
test_job:
stage: test
script:
- echo "Running unit tests"
- ./run-tests.sh
GitLab CI/CD enables automation for efficient workflows. Utilize .gitlab-ci.yml
, GitLab Runner, and testing/deployment integration for continuous improvement and optimized processes. To ensure your pipeline is functioning as intended, you can validate the syntax and debug any issues within the GitLab pipeline editor.
By automating your build and test processes, you can catch errors early and save time, making your development cycle more efficient and reliable.
Automating Builds and Tests
Automating the build and test processes in your GitLab CI/CD pipeline is a game-changer for maintaining a stable and efficient workflow. GitLab’s CI/CD pipelines are defined using .gitlab-ci.yml
files, which allow you to automate repetitive tasks, improve code quality, and accelerate delivery. For instance, a simple pipeline configuration might look like this:
build-job:
stage: build
script:
- echo "Hello, $GITLAB_USER_LOGIN!"
test-job1:
stage: test
script:
- echo "This job tests something"
test-job2:
stage: test
script:
- echo "This job tests something, but takes more time than test-job1."
- sleep 20
By leveraging GitLab’s integrated CI/CD, you can ensure that every commit or merge request is automatically built and tested, leading to more transparent updates and a more stable environment.
Here are some examples of .gitlab-ci.yml
configurations for different programming environments:
- Ruby on Rails: Define test and build stages, and include database configurations.
- Python: Set up build and linting stages, and specify dependencies.
- Rust: Configure the build and test stages, and include necessary compiler options.

Reviewing Code and Managing Merge Requests
Merge Requests (MRs) are central to collaboration in GitLab. They allow you to propose changes, solicit feedback, and ensure code quality before integrating new code into the main branch. Start by creating a new branch for your changes, and once you’re ready, open a merge request.
To streamline the review process, GitLab provides a suite of tools. Use commit message templates to maintain a clear history, and draft merge requests to gather early feedback. Here’s a quick checklist for managing MRs effectively:
- Ensure your code adheres to project guidelines
- Assign reviewers and set approval rules
- Discuss changes and address suggestions
- Resolve any merge conflicts promptly
With GitLab’s robust MR system, you can automate certain checks, like running tests through CI/CD pipelines, to catch issues early. This not only saves time but also enhances the overall quality of your project.
Remember to regularly sync your branch with the main branch to minimize conflicts. When everything is approved, you can merge your changes, using methods like squash and merge for a cleaner history.
Resolving Merge Conflicts
When collaborating on GitLab projects, merge conflicts are an inevitable part of the process. They occur when multiple developers make changes to the same lines of code or when one developer’s changes are not up to date with changes merged into the main branch. Resolving these conflicts promptly is crucial to maintaining a smooth workflow.
To address merge conflicts, follow these steps:
- Fetch the latest changes from the main branch.
- Merge the changes into your feature branch.
- Identify the files with conflicts and carefully review the differences.
- Decide on the final code that should be in the merged file.
- Commit the resolved files to update the merge request.
It’s essential to communicate with your team members during this process to ensure that the resolutions reflect the team’s consensus.
Remember, the goal is to integrate all changes in a way that preserves the integrity of the codebase. Utilize GitLab’s built-in tools, such as the merge request diffs and conflict resolution editor, to assist you. If conflicts are complex, consider a pair programming session to resolve them collaboratively.

Remember to check the ‘Settings’ of your project to configure the visibility and access controls for your Pages. GitLab offers detailed documentation and troubleshooting guides to help you if you encounter any issues during the setup process.
Securing Your GitLab Projects
Implementing Access Controls
To secure your GitLab project, it’s crucial to restrict access to authorized individuals. Start by configuring access tokens which serve as secure credentials. These tokens can be project-specific or group-based, ensuring that only the right eyes have the necessary permissions.
- Under Repository access, select the scope for your token. Opt for minimal necessary access to maintain security.
- In the Permissions section, define the access levels for the token. This granularity helps in maintaining control over your repositories and account.
Ensure that project and group access tokens include the api and read_repository scopes. Personal access tokens should also have read_user.
Remember, tokens linked to roles like Owner or Maintainer offer extensive control, so assign them judiciously. For a comprehensive understanding of permissions and roles, the GitLab documentation is an invaluable resource.
Managing Sensitive Data with Environment Variables
In the realm of software development, protecting sensitive data is paramount. Environment variables serve as a secure method to store credentials, API keys, and other sensitive information away from the codebase. By using environment variables, you can ensure that sensitive data is not accidentally committed to version control, thus reducing the risk of exposure.
To set up environment variables in GitLab, navigate to your project’s settings and look for the CI/CD section. Here, you can define variables that will be accessible during the pipeline execution. It’s crucial to restrict the visibility of these variables to maintain security. For instance, you can set variables to be ‘Protected’, meaning they will only be available to pipelines running on protected branches or tags.
When configuring environment variables, always use descriptive names that convey the purpose of the variable without revealing the actual sensitive data.
Remember to periodically review your environment variables and update them as necessary. This practice is part of maintaining a secure GitLab installation and ensures that your data remains protected.
Enabling Two-Factor Authentication
Enhancing the security of your GitLab account is crucial, and enabling Two-Factor Authentication (2FA) is a straightforward way to add an extra layer of protection. Navigate to your Account Settings and locate the ‘Two-factor Authentication’ section to begin the setup process.
To enable 2FA, follow these steps:
- Click the blue button that says ‘Enable two-factor authentication‘.
- Follow the on-screen instructions to complete the setup.
- Record the recovery codes provided and store them in a secure location.
After enabling 2FA, you will need to enter both your password and a verification code from your mobile device whenever you sign in to GitLab. This ensures that even if your password is compromised, your account remains protected.
Remember to update your linked accounts and services with the new authentication method to maintain access to your repositories and integrations.
Optimizing Your Workflow with GitLab Features
Utilizing Issue Trackers for Task Management
GitLab’s built-in issue tracker is a powerful tool for teams to effectively manage tasks. Create, assign, prioritize, and track issues with ease, ensuring nothing slips through the cracks. This feature fosters clear communication and collaboration among team members.
Italics are used to emphasize the importance of prioritization in task management. By setting priorities, teams can focus on what’s most critical, ensuring efficient workflow and timely completion of tasks.
Effective issue tracking is not just about logging tasks; it’s about creating a workflow that aligns with your team’s goals and processes.
Here’s a quick guide to get started with GitLab’s issue tracker:
- Create issues for bugs, feature requests, or any other tasks.
- Assign issues to the appropriate team members.
- Set priorities to help organize the workflow.
- Use labels to categorize and filter issues.
- Track progress with milestones and burndown charts.
Remember, the key to successful issue tracking is maintaining a system that is transparent and accessible to all team members.
Leveraging Labels and Milestones
Efficiently managing your project’s workflow is crucial, and GitLab provides powerful tools like labels and milestones to help you do just that. Labels are essential for categorizing and prioritizing issues, allowing you to streamline your focus on specific areas of work. Milestones, on the other hand, enable you to track progress over time and align your team with project deadlines.
To get the most out of these features, consider the following steps:
- Define a clear labeling system that reflects your project’s needs.
- Create milestones that correspond to your project’s phases or sprints.
- Assign labels to issues and merge requests for better organization.
- Use GitLab’s roadmaps to visualize progress across milestones.
By consistently applying labels and milestones, you’ll enhance the visibility of your project’s progress and ensure that everyone on the team is on the same page.
Remember, while labels help you filter and find relevant issues quickly, milestones give you a high-level view of your project’s trajectory. Utilize both to maximize your project management efficiency.
Customizing Your GitLab Dashboard
Your GitLab dashboard is the mission control for your projects, providing a quick overview and access to your work. Customizing your dashboard can significantly enhance your productivity by ensuring that the most relevant information is always at your fingertips.

GITLAB
In the last article, we saw the various parts of GitLab, its architecture and how GitLab works. If you haven’t already, I suggest reading the previous article first before reading this one. Here is the link
GitLab, A Complete Beginner’s Guide!
In this article lets look at how to set it up locally on your Windows PC, so that you can have your very own GitLab setup running right at your home or organization!
If you are using Mac or Linux, you can follow the links below.
Complete Guide To Setting Up GitLab Locally On Mac.
Complete Guide To Setting Up GitLab Locally On Linux PC..!!
So let’s begin!
Things you will need
All you need are a computer running Windows OS with enough resources (CPU, memory, and disk space) for running the GitLab Server and GitLab Runner. How much resources is enough depends on how much performance you need, the more you have the better it is!
You can also set it up on the cloud over at Gitlab.com, but
- the free plans have some limitations in terms of processing power and hard disk space.
- Also doing it locally gives you more control over the setup and
- it will also be an opportunity to learn you more about GitLab
Hence I suggest taking this route of a local installation.
If you are part of a larger organization, and you wish to install it on the cloud, then you can always take a look at the paid plans of GitLab here link
Approach to install GitLab on Windows
Okay, let’s get back to the task in hand.
As we saw in the previous article GitLab consists of 2 parts.
- GitLab Server and
- GitLab Runner
Also, we have learned in the previous article that it is preferable to set the GitLab server and runners on separate computers. But I am going for a home set up, so I will be setting them both upon the same Windows computer.
The GitLab Server relies heavily on Linux technologies and hence it cannot be installed in our Windows PC natively. If you do some research, there are ways you can do it through the Linux subsystem in windows, but we are not going to take that approach.
The
problem with these workarounds are
- The installation process is a bit complicated and is not recommended for beginners.
- They are only guaranteed to work on a version to version basis. What I mean by that is you need to have a particular version of Windows and a particular version of GitLab for everything to run smoothly. If you update your Windows or if you wish to upgrade your GitLab then you might break your GtiLab set up. Since both Windows and GitLab updates come frequently, it is not such a good idea to waste time trying to fix things every few months.
- It is unofficial and hence support for future versions cannot be guaranteed.
- These unofficial methods will bring their own limitations as opposed to running natively on Linux
Due to these above reasons, we are going to go for a more stable approach of installing the GitLab server in a virtual environment. We will also see in this article the ways to make it run as smoothly and efficiently as possible while making sure it consumes as few resources as possible.
So this
is what we are going to do
- Install the GitLab Server on a Virtual Box running Ubuntu server
- Install GitLab runner natively on Windows.
This approach takes away the cons of using unofficial hacks, as it will work on all versions of you Windows and GitLab and you don’t need to worry too much while updating your software either!
By following the step by step guide shown below you should be able to set everything up and running in an hour or 2 (depending upon how good your internet connection is, it can take longer!)
GitLab Installation Process
STEP#1: Download and install VirtualBox
You can download and install VirtualBox from this link
Just click on the Windows hosts and the download should start automatically. The installation process is pretty straightforward, you can just accept the default options and click through to complete the process.
Once the installation is completed you can open VirtualBox from the Start menu in Windows.
STEP#2: Install Ubuntu Server as a Virtual Machine in your Windows PC.
The next step is to get a Linux distro to install our GitLab server. For this purpose, I recommend Ubuntu Server. I chose this particular distro for 2 reasons.
- Ubuntu is known for its stability.
- GitLab Server software has support for Ubuntu
- The server edition is chosen so that it will consume fewer resources on your computer.
For this first, you need the Ubuntu Server image. You can download it from this link.
Ubuntu usually offers 2 sets of packages for us to choose from.
- Long term support version: Has a support period of 5 years
- Latest Version: has all the latest features.
I suggest you go for the LTS one, but then the latest version should also work just fine. So click on a “Download” button and your download should start automatically. It will take some time to complete as the iso is around 900MB.
Once the download is complete you can proceed to the installation process on VirtualBox.
STEP#3: Install Ubuntu Server on VirtualBox
Open VirtualBox Application and click on the “New” button
A window like this should pop up
Give your virtual machine a name and choose Linux for type and ubuntu 64 bit for version and click “Continue”.
The next screen usually asks for RAM. GitLab recommends 8GB for a GitLab system with 100 users, I suggest a minimum of 2GB RAM for a home set up, you can give more if you can, just make sure you don’t allot more than 50% of your total available RAM.
Once you have allocated RAM space, Click “Continue” to the next page.
Next, you will be prompted for hard disk. Make sure “Create a virtual hard disk now” is selected and click “Create”
Accept
the default “VDI (VirtualBox Disk Image)” and click
“Continue”
Accept “Dynamically Allocated” and Press continue. This option allocates hard disk space to the virtual machine on the run, so that as you use the more space, more will be allocated.
I suggest you allocate at least 25GB of space to the virtual machine, you can allot more if you can. Once you have chosen the disk space click create
Once you have done this, you should be taken back to the main window of VirtualBox and you should see the virtual machine you just created on the left pane of the window as shown in the screenshot below.
Next click on the “Settings”
And click on storage -> empty -> disk icon -> “Choose a disk file”
Select the ubuntu server iso image you have just downloaded and press ok. This is equivalent to inserting the Ubuntu disk in a real machine.
Next, go to settings->Network and choose “Bridged Adapter” in the “Attached to:” drop-down menu and press “OK”
I have explained the reason behind using these network settings in detail in this article, you can go ahead and read that if you are into computer networks.
The short explanation is, we will not be able to access the GitLab server from our other machines on the network unless we choose this option.
That’s it, the configuration is done!
You can now go ahead and click the start button!
Now the installation process will start. Since we have chosen to go with “Ubuntu server” in order to minimize the resource consumption (so that GitLab can take up as many resources as it needs) we don’t get a fancy Graphical UI, like in the desktop version of Ubuntu. You need to navigate the menus during installation only using Keyboard (tab, enter and arrow keys) since the Ubuntu server doesn’t come with mouse support. So go through the process and get it done.
STEP#4: Get the IP address of your ubuntu server
Okay now
once you got the Ubuntu server up and running, you need to find its IP address
and make a note of it.
To do that, use the “ifconfig” command on your Ubuntu server’s terminal
STEP#5: Download and install GitLab server
To download GitLab server, go to the official link on the Gitlab’s Website
As you can see GitLab official supports several Linux distros, even a Raspberry Pi 2’s Raspbian! We are interested in Ubuntu, so click on the Omnibus Ubuntu Link on as shown in the screenshot above.
Once you click on Ubuntu, the commands you need to enter to install GitLab server will be shown to you.
I am not showing each instruction here since GitLab updates the information presented on their website all the time and that can make this section of the article outdated. Just follow the step by step instructions given in the link to install the GitLab Server on your VM.
Just type in the commands shown there on you Ubuntu server’s terminal one by one to get GitLab Server installed.
A couple of tips on the GitLab installation instructions
Tip#1
In the postfix installation step (step 1 last command on the GitLab website)
sudo apt-get install -y postfix
you can skip the mail option by choosing the “no configuration” option as shown in the screenshot below.
Tip#2
In the last command of step 2 at GitLab website
sudo EXTERNAL_URL="https://gitlab.example.com" apt-get install gitlab-ee
Make sure you replace the URL with the IP address of the VM that we have made a note of in Step 5 above like this
sudo EXTERNAL_URL="192.168.0.116" apt-get install gitlab-ee
Or to be more precise just place the VM’s IP address that we obtained in Step#4 in its appropriate place
sudo EXTERNAL_URL=”<Your VM’s IP address>” apt-get install gitlab-ee
This step will take a while, so be patient. In my machine it took 4 minutes 48 seconds as shown in the screenshot below, yours can vary depending on the processing power it has.
Once done it will show u something like in the screenshot below.
Once it’s done, you can go ahead to your favorite browser and type in the IP address of your VM and check if the installation has succeeded.
And voila! GitLab server installation has succeeded!
Go ahead and follow the onscreen instructions to set up your password, accounts and everything else!
STEP#6: Download GitLab runners
Before installing GitLab runners you need to install Git on your Windows PC. You can download the latest version of Git in this link.
Now that we have set up the Gitlab server and Git, the next step is to set up the GitLab runner!
At the time of writing this article, the installation process goes like this:
Make a folder on your computer and go to either this link for 32bit version or this link for 64bit version to download the binaries and put them in the folder you created
For getting the most up to date instruction, I am gonna ask you to follow the process given in the GitLab website
STEP#7: Connect the GitLab server to the GitLab runner
GitLab
calls this process of connecting the Server to Runner as “Registering the
GitLab Runner to the Server”
You can follow the instructions for Windows in this link to do the same.
Scroll down to the windows section and you will see something similar to this
Step# 7.1: Start the registration process
To enter these commands you need to open a command prompt with administrator privileges. For this just type cmd on the search menu, right-click on Command prompt and choose run as administrator
After that, just go to the folder to which you have downloaded the Gitlab Runner to and copy the path to that folder
Next, go back to the command line and give the following command
cd <path you copied>
Run the following command to start the registration process
gitlab-runner-windows-amd64.exe register
As shown in the screenshots above, enter your Virtual Machine’s IP address when prompted. Make sure you add “http://” before the IP address.
Once the IP address is entered, the next prompt appears asking you to enter a token, so let’s first go get a token from our GitLab server.
Step#7.2: Obtain token from GitLab Server
Go to your browser and enter the GitLab Server’s IP address. Once you have logged in you can create your first project by clicking on the respective pane as shown in the screenshot below.
Just give the project a name and click on the create project button. The other field should get populated automatically.
Once you click the button as shown in the screenshot above, you will be taken to your project page.
From there just click on Settings->CI/CD and scroll down a bit and click the “Expand” button next to “Runners” and you will find the token you need as shown in the screenshot below.
This token basically connects your project on the GitLab Server to the GitLab runner.
Step#7.3: Enter the token
Now that we have the token let’s enter it on the Command prompt
Once
entering the token, you will be prompted to give the runner a description, go
ahead and do that.
After that, you will be asked to enter some tags.
What are tags? Why are they needed for GitLab runners?
The
better term for tags can be capabilities.
Consider
this scenario.
Assume you are working in a large team of 1000 developers, who are doing say 50 different projects and your GitLab system has 100 different runners set up with several capabilities to do specific tasks. Some projects may need C compilers, while others may need python interpreters.
Now in order to connect a given project with a free-runner, we need some sort of parameter to tell the GitLab server that this particular free runner is capable of running the scripts needed for that particular job.
This is where tags come into the picture. By giving tags like “C” or “Python” a single runner can be connected to multiple projects and a single project can execute its jobs on several runners to ensure the best possible performance.
Using
these tags the Gitlab server can find a runner with the specific capability to
use for a given job. So give some suitable tags that will imply the
capabilities of your runner.
Once that is done, you will be prompted to enter “executor”.
Executors are programs that run our CI/CD scripts. Type shell and press enter
This will end the registration process the Runner to the server
Once registered you can start the GitLab runner as a Service (background task) by issuing the commands
gitlab-runner-windows-amd64.exe install gitlab-runner-windows-amd64.exe start
As you can see in the screenshot below, in the task manager app we can see that our gitlab-runner service is running!
Test to see if everything works
By following the 7 steps above, you should have a set up with GitLab Server and Runner running on your system. Its time to test and see if everything works the way it is supposed to work!
First, let’s test the GitLab server by creating a repo and pushing it to the server.
Testing GitLab Server
STEP#1: Make a test git repo
Let’s make a simple git repo on a new folder on our Desktop and push it to the GitLab server.
So open your Git-Bash app, which got installed as you were installing git.
Once opened type in the following commands
cd cd Desktop mkdir test_project cd test_project touch test.c
The above lines of command are just the fancy way of creating a folder named test_project on your Desktop and a file named test.c inside it. You can also do it through the Graphical User Interface if you want to.
So next, please open the C file using your favorite text editor and type in a simple program for testing, something like the following.
#include <stdio.h> int main() { printf("Hello Embedded Inventors!"); return 0; }
Next, let’s initialize a git repository on our test_project folder. So go back to the terminal cd into the test_project folder and type in the following command
You should receive a reply saying “Initialized empty Git repository”
STEP#2: Push it to the server
Now that we have our git repo ready, let’s push it to our git server. To do that login to your GitLab and go to the project we created earlier. There GitLab shows us the commands needed to push our repo to the server.
First, let’s configure our name and email on the git repository to the ones set on the GitLab server
So enter
the following command.
git config --global user.name "<enter your name here>" git config --global user.email "<enter your email here>"
Next, we need to connect our server and our repository. To do that just enter the following commands
git remote add origin <your project URL>.git
In my case it is
git remote add origin http://192.168.0.115/EI/test-project.git
To find your project URL, just copy the address bar of your browser while you are on your project’s page in GitLab
Then add our test.c file and commit the changes using the following commands
git add . git commit -m"first commit"
Then push
your git repo onto the GitLab using the command
git push -u origin master
You will be prompted to enter the user name and password of your GitLab account, once done go to your browser and just refresh the page and you should be able to see your test project page in GitLab!
Testing GitLab Runner
STEP#3: Make a simple bash script to build the test.c
file
Create a bash script on your project folder
cd cd Desktop/test_project touch build.ps1
Edit it so that it looks something like this
gcc test.c -o test echo "Build completed"
STEP#4: Create and edit .gitlab_ci.yml to run the
above script
What is .gitlab-ci.yml and why it is needed? This is the file that contains the instructions for the GitLab runners to execute the CI/CD tasks. It should be present in the project’s root folder. It can be used to test if a commit builds correctly, passes some unit tests and if it needs packaging and deployment.
You can
learn more about how to configure it from the official quick start tutorial
here
For the
purpose of testing our installation let’s create a file named .gitlab-ci.yml in
the test_project folder and put the following lines in there.
Make sure you are in the right directory
cd cd Desktop/test_project
Create the file using the command
Open it with your favorite text editor and type the following lines into it.
build: script: - powershell -File build.ps1 tags: - test
The last line tells the GitLab server to use the GitLab runner with the tag named “test”. If you gave your GitLab runner installation a different tag, make sure you make the appropriate change to the above lines.
Also,
make sure you use spaces instead of tabs at the beginning of the above lines.
Now add it to the git repository and push it to the Gitlab server
git add . git commit -m"gitlab yml added" git push
Now let’s get back to our GitLab server’s URL and see if it worked. Go to the project page and click on CI/CD
You will
be taken to the pipeline page which shows the result of your latest commit.
It will
take a minute or so before it completes the pipeline and as you can see in the
screenshot above, mine took 41 seconds to complete and the status is
“passed”
If you
click on “jobs” under the CI/CD menu, you will be taken to another
page which shows you more information about the execution of our yml file
Next click on “passed” as shown in the screenshot above, this will take you to another page which will look something like this.
As you can see, our build.ps1 gets executed by the GitLab runner and it succeeds to compile our project.
And with that, I will conclude this tutorial!
