Using GitLab’s Version Control
Understanding Version Control
Welcome to the foundational concept of GitLab: version control. Version control is the management of changes to documents, computer programs, large websites, and other collections of information. Changes are usually identified by a number or letter code, termed the ‘revision’. Each revision is associated with a timestamp and the person making the change. Revisions can be compared, restored, and with some types of files, merged.
Version control systems (VCS) serve as a critical tool in the software development process. They allow multiple people to work on a project simultaneously without stepping on each other’s toes. It’s a system that records changes to a file or set of files over time so that you can recall specific versions later. For those just starting with GitLab, here’s a simple breakdown of key terms:
- Commit: A change, or set of changes, to one or more files in the source code on a given Git branch.
- Branch: A version of a project’s working tree. You create a branch for each set of related changes you make.
- Merge: The process of integrating changes from one branch into another.
Remember, the goal of version control is not just to keep track of changes, but to facilitate collaboration and maintain a comprehensive history of a project’s evolution.
When configuring GitLab for self-hosting, it’s important to consider aspects such as user management, repository management, CI/CD, migration, security considerations, and limitations. This requires technical expertise and resources for maintenance and support.
Committing Changes
Once you’ve made changes to your files in a GitLab project, the next step is to commit those changes. A commit is like a snapshot of your project at a particular point in time, capturing the current state of your work. To commit changes, you’ll need to stage them first, which means selecting the specific changes you want to include in the commit.
Here’s a simple process to follow:
- Stage your changes using
git add
. - Write a clear commit message that describes the changes using
git commit -m "your message"
. - Push the commit to the remote repository with
git push
.
Remember, each commit should be a self-contained unit of work. This makes it easier to understand the history of your project and to roll back changes if necessary. It’s also important to write meaningful commit messages that provide context for the changes made.
Committing regularly and pushing your changes to the remote repository ensures that your work is safely backed up and available to collaborators. It’s a fundamental practice for effective version control in GitLab.
Branching and Merging
Branching and merging are fundamental to managing code in GitLab. Branches allow you to work on new features or fixes without affecting the main codebase. When your work is ready, you create a merge request (MR) to integrate your changes into the main branch. Here are some best practices to follow:
- Aim to make and merge updates on the same day to avoid your branch falling far behind the master, which can lead to merge conflicts.
- When creating an MR, select the option to Delete source branch when merge request is accepted to maintain a clean history.
- Ensure that your manager or someone with maintainer access can merge your MR. If they can’t, a yellow triangle with an exclamation point will indicate this next to their picture.
It’s crucial to get your merge request merged quickly. Making single, small changes quickly will ensure your branch doesn’t fall far behind master, creating merge conflicts.
Remember, when you create a merge request, you select two branches to compare. The differences between the two branches are shown as a diff in the merge request. Each change should be reviewed and tested to ensure quality before merging.
Issue Tracking and Management
Creating and Assigning Issues
Creating issues in GitLab is a straightforward process that begins with navigating to the relevant project. Select ‘Issues’ from the sidebar, then click the ‘New issue’ button. Here’s a quick rundown of the steps to follow:
- Add a Title for the issue.
- Fill in the Description with all necessary details.
- Use the ‘preview’ feature to ensure proper formatting.
- Decide on the issue’s confidentiality.
- Assign the issue to the appropriate individual.
- Optionally, add labels, milestones, weights, and due dates.
- Submit the issue by clicking the blue ‘Submit issue’ button at the bottom.
Remember, transparency is key in GitLab’s culture. Only mark issues as confidential if they contain sensitive information that should not be public.
If you mistakenly create an issue in the wrong project, don’t worry—you can move it. This flexibility ensures that issues are always matched with the most relevant project, maintaining organization and clarity within your team’s workflow.
Managing Issue Boards
GitLab’s issue boards are a powerful tool for streamlining your project management workflow. Boards in GitLab make it possible to visualize and manage lists of issues which can be defined by one of three ways: Labels, Team members, and Milestones. This flexibility allows you to tailor the board to the specific needs of your project.
To effectively manage your issue boards, consider the following steps:
- Define columns for each stage of your workflow (e.g., To Do, In Progress, Review, Done).
- Assign issues to the relevant column based on their current status.
- Use labels to categorize issues and filter the board view accordingly.
- Assign team members to issues to clarify responsibility.
- Set milestones for batches of issues to track progress towards major goals.
Remember, the key to successful issue board management is regular updates and clear communication with your team.
By regularly updating the status of issues and ensuring that all team members are aware of their responsibilities, you can maintain a clear overview of your project’s progress and quickly identify any potential bottlenecks.
Tracking Progress
Keeping track of your project’s progress is crucial to ensure timely delivery and to identify any potential roadblocks. GitLab’s issue tracking system provides a clear overview of tasks and their statuses. By using labels, milestones, and due dates, you can organize and prioritize work effectively.
To monitor progress, consider setting up a dashboard that displays key metrics. This could include the number of open vs. closed issues, progress on current milestones, or the burn down chart for the current sprint. Here’s an example of how you might structure this data in a Markdown table:
Metric | Current Sprint | Previous Sprint |
---|---|---|
Open Issues | 10 | 15 |
Closed Issues | 20 | 18 |
Milestone Progress | 75% | 60% |
Remember, regular reviews of these metrics can help you adjust strategies and ensure that your team is on track to meet its goals.
GitLab also offers various reports and analytics tools that can help you visualize progress over time. These tools can be particularly useful for spotting trends and making data-driven decisions.

Configuring jobs in GitLab CI/CD is a critical step to automate your build, test, and deployment processes. Each job is defined within the .gitlab-ci.yml
file, which GitLab uses to manage the pipeline’s workflow. To get started, specify the image or services your job requires, script commands to run, and define job dependencies.
Jobs are the building blocks of a pipeline. They can be organized into stages that run sequentially, allowing for complex workflows. Here’s a simple example of job configuration in a .gitlab-ci.yml
file:
stages:
- build
- test
build_job:
stage: build
script:
- echo "Compiling the code..."
- compile
test_job:
stage: test
script:
- echo "Running tests..."
- run_tests
Remember to tailor your jobs to the needs of your project. For instance, you might have jobs for linting, compiling, testing, and deploying. Each job should be as atomic as possible to facilitate troubleshooting and improve build times.
It’s essential to keep your pipeline efficient and maintainable. Avoid redundant tasks and optimize your scripts for performance.
By configuring jobs thoughtfully, you can leverage GitLab’s CI/CD as one application with one data store, which makes it possible to visualize the status of each environment and deployment. Close feedback loops and ensure that your team can respond quickly to any issues that arise.
