Creating a New Repository

Setting up a GitLab account

To get started with GitLab, you’ll need to set up an account. Here’s how:

1. Click on your user’s icon/avatar and choose Settings.
2. Navigate to ‘Access Tokens’ and create a new token named ‘jenkins’ with ‘api’ scope. You can choose to set an expiration for the token, but it’s optional.
3. Copy the token immediately as it cannot be accessed after leaving the page.
4. In Jenkins, go to the Global Configuration page and find the GitLab configuration section.
5. Add a new credential by selecting ‘GitLab API token’ and paste your GitLab user’s API key into the ‘API token’ field.
6. Click the ‘Test Connection’ button to ensure the connection is successful.

Creating a new project

Once you have set up your GitLab account, the next step is to create a new project. To do this, follow these simple steps:

1. Navigate to your GitLab dashboard and click on the ‘New project’ button.
2. Fill in the required information, such as the project name and visibility level.
3. Choose the repository type, either Git or Mercurial.
4. Optionally, you can add a project description and choose the project’s initialization method.
5. Finally, click on the ‘Create project’ button to create your new project.

Configuring repository settings

After creating a new project in GitLab, the next step is to configure the repository settings. This step allows you to customize various aspects of your repository to suit your needs. To configure the repository settings, follow these steps:

1. Open the project in GitLab and navigate to the ‘Settings’ tab.
2. In the left sidebar, click on ‘Repository’.
3. Here, you can modify settings such as the repository name, description, visibility, and default branch.
4. You can also enable features like ‘Merge Requests’ and ‘Wiki’ for your repository.
5. Make sure to click on ‘Save changes’ to apply your modifications.

By configuring the repository settings, you can ensure that your project is organized and accessible to your team members. It also allows you to define the workflow and collaboration features that best fit your development process.

Adding and Committing Files

Cloning the repository

After setting up your GitLab account and creating a new project, you can clone the repository to your local machine. Cloning allows you to create a local copy of the repository, including all its files and history. To clone the repository, you can use the following command:

$ git clone [repository URL]

Once the cloning process is complete, you will have a local copy of the repository on your machine. This is useful for making changes to the project and pushing them back to the remote repository. If you are using GitLab Premium, you can also take advantage of additional features and collaboration tools.

To clone the repository via the HTTP protocol, you can use the following command:

$ git clone http://[repository URL]

Remember to replace [repository URL] with the actual URL of the repository you want to clone.

Adding files to the repository

To add files to the repository, follow these steps:

1. Make sure you have cloned the repository to your local machine.
2. Navigate to the repository directory using the command line.
3. Use the git add command to stage the files you want to add. You can specify individual files or use wildcards to add multiple files at once.
4. After staging the files, use the git commit command to create a new version of the repository with the added files.
5. Optionally, you can use the git status command to check the status of the repository and see the files that have been staged.

Remember to regularly commit your changes to keep track of the different versions of your files.

Committing changes

After making the necessary changes to your files, it’s time to commit them to the Git repository. The commit operation creates a new persistent snapshot called commit object of the managed files. This snapshot is immutable, meaning it cannot be changed once created.

To commit your changes, follow these steps:

1. Use the git status command to check the status of your files and ensure that all changes are staged.
2. Run the git commit command followed by a descriptive message to create the commit.
3. Optionally, use the git show command to view the changes made in a specific commit.

Remember to commit your changes regularly to keep track of your progress and maintain a clear history of your project.

Creating and Managing Tags

Understanding tags in GitLab

Tags in GitLab are used to mark specific points in your repository’s history. They are typically used to indicate important milestones such as releases or versions. Tags are lightweight references that point to a specific commit, allowing you to easily navigate and reference specific points in your project’s history.

Tags can be created and managed directly in GitLab’s user interface or through Git commands. Once a tag is created, it can be pushed to the repository, making it accessible to other team members. Tags can also be annotated with additional information such as release notes or changelogs.

When working with tags, it’s important to follow naming conventions to ensure consistency and clarity. Using descriptive names that reflect the purpose or content of the tag can make it easier to understand and navigate your repository’s history.

To view and manage tags in GitLab, you can use the GitLab UI or command-line tools. This allows you to easily browse and search for specific tags, delete tags if necessary, and perform other tag-related operations.

In summary, tags in GitLab provide a way to mark important points in your repository’s history, making it easier to navigate and reference specific commits or versions. By following best practices and using descriptive names, you can ensure clarity and consistency in your tagging workflow.

Creating a new tag

To create a new tag in GitLab, you have two options: through the user interface (UI) or via the command line interface (CLI). If you prefer the UI, simply navigate to Code -> Tags -> New Tag and follow the prompts. If you’re more comfortable with the CLI, you can use the command ‘git tag’ to create the tag. Creating a tag will trigger a pipeline that…

Pushing tags to the repository

After creating a new tag, the next step is to push the tag to the repository. This ensures that the tag is visible to other users and can be accessed when needed. To push a tag to the repository, use the following command:

git push origin <tag_name>

Replace <tag_name> with the name of the tag you want to push. This command will push the tag to the remote repository, making it available for others to see and use.

It’s important to note that pushing a tag does not automatically push the associated commits. If you want to push both the tag and the commits, you can use the --follow-tags option with the git push command.

git push --follow-tags

This will push both the tag and any associated commits to the repository.

Viewing and managing tags

Once you have created tags in GitLab, you may need to view and manage them. GitLab provides several options for viewing and managing tags within your repository.

To view the tags in your repository, you can navigate to the ‘Tags’ page. This page displays a list of all the tags in your repository, along with information such as the tag name, commit hash, and tag message.

If you want to manage tags, GitLab allows you to delete tags both locally and from the remote repository. To delete a tag locally, you can use the ‘git tag -d’ command followed by the tag name. To delete a tag from the remote repository, you can use the ‘git push –delete origin’ command followed by the tag name.

Additionally, GitLab provides a user-friendly interface for managing tags. You can easily create new tags, edit existing tags, and perform other tag-related actions directly from the GitLab web interface.

Remember to use tags judiciously and follow best practices to ensure efficient and organized version control in your projects.

Tagging Best Practices

Naming conventions for tags

When it comes to naming conventions for tags in GitLab, it’s important to follow a consistent and descriptive approach. Here are some best practices to consider:

• Use meaningful names that clearly indicate the purpose or significance of the tag.
• Avoid using generic or ambiguous names that may cause confusion.
• Consider including version numbers or release identifiers in the tag name.
• Use lowercase letters and hyphens to separate words in the tag name.

Following these naming conventions will help maintain clarity and organization in your GitLab repositories.

Tagging specific commits

When working with GitLab, you may often need to refer to specific commits for various purposes. Whether you want to view the changes introduced between two different branches or identify all commits with a certain keyword in their commit message, Git provides several options to address commits.

One way to refer to a commit is by using a commit hash or a tag. A commit hash is a unique identifier for a commit, while a tag is a named pointer to a commit. You can create lightweight tags, which are simple references to a commit, or annotated tags, which contain additional metadata such as the name and email of the person who created the tag, the tagging message, and the date of the tagging.

To view the commit a tag points to, you can use the command git show <tag>. Alternatively, you can use the command git log --grep=<pattern> to list all commits that match a specific pattern in their commit message.

If you want to filter the log output based on the author or committer, you can use the options --author=<name> or --committer=<name>. These options allow you to include only the commits that were authored or committed by a specific person.

Remember, when addressing commits, it’s important to use the appropriate commit reference and take advantage of Git’s powerful features to navigate and analyze your repository’s history.

Annotating tags with additional information

Annotated tags in GitLab include additional information like the tagger’s name, email, and message. They provide more context and are often preferred for release versions. To annotate a tag, use the git tag -a command followed by the tag name. You will be prompted to enter a message for the annotation. Annotated tags are useful for documenting important details about a specific version or release.

Deleting Tags

Removing tags locally

Deleting tags locally in GitLab is a straightforward process. To delete a local Git tag, you can use the git tag command with the -d option. For example, to delete a tag named tag_name, you would run the following command:

git tag -d tag_name

This will remove the tag from your local repository. It’s important to note that deleting a tag locally does not automatically delete it from the remote repository. If you want to remove the tag from the remote repository as well, you will need to push the deletion. We’ll cover how to delete tags from the remote repository in the next section.

Deleting tags from the remote repository

When it comes to deleting tags from the remote repository in GitLab, there are a few important points to keep in mind:

• To delete a tag, you can use the git push command with the --delete flag followed by the name of the tag. For example, git push origin --delete tag_name.
• Deleting a tag from the remote repository will remove it from all clones of the repository.
• It’s important to note that deleting a tag is a permanent action and cannot be undone. Make sure to double-check before deleting any tags.

If you need to remove a tag from the remote repository, follow these steps:

1. Open your terminal or command prompt.
2. Navigate to the local repository where the tag is located.
3. Use the git push command with the --delete flag and the name of the tag to delete it from the remote repository.

Remember to exercise caution when deleting tags and always verify that you are deleting the correct tag.

Tagging in Continuous Integration

Integrating tags with CI/CD pipelines

Integrating tags with CI/CD pipelines is a crucial step in managing your software releases. By tagging specific commits, you can easily identify and track the versions of your code that are deployed in different environments. Here are some best practices to follow when integrating tags with CI/CD pipelines:

1. Use descriptive and meaningful tag names to clearly indicate the purpose or significance of each release.
2. Ensure that the tags are pushed to the repository after the successful completion of the CI/CD pipeline.
3. Make sure to view and manage the tags regularly to keep track of the different versions of your code.

Implementing these practices will help you streamline your release management process and ensure that your software is deployed accurately and efficiently.

Triggering builds with tags

To trigger builds when a new tag is pushed in GitLab, you can follow these steps:

1. In the GitLab webhook configuration, add ‘Tag push events’.
2. In the job configuration under ‘Source code management’, select ‘Advanced…’ and add ‘+refs/tags/:refs/remotes/origin/tags/‘ as the Refspec. You can also use ‘Branch Specifier’ to specify which tag needs to be built (example ‘refs/tags/${TAGNAME}’).
3. Save the configuration and run the job once before the list is populated.

By implementing these steps, you can ensure that your builds are triggered automatically when new tags are pushed to your repository.

Tagging in Collaboration

Sharing tags with team members

When working on a project in GitLab, it’s important to share tags with your team members to ensure everyone is on the same page. Sharing tags allows for easy collaboration and communication, especially when it comes to tagged releases. Here are some best practices for sharing tags with team members:

• Implement a table for presenting structured, quantitative data. Ensure it’s succinct and formatted correctly in Markdown.
• Use a bulleted or numbered list for less structured content, like steps, qualitative points, or a series of related items.

Remember, tags are a powerful tool for organizing and managing your project, so make sure to share them with your team to maximize efficiency and collaboration.

Collaborating on tagged releases

When collaborating on tagged releases in GitLab, it’s important to follow some best practices to ensure smooth collaboration and effective communication. Here are a few tips:

• Coordinate with team members: Before creating a new tag, make sure to communicate with your team members to ensure everyone is on the same page.

• Use descriptive tags: When creating a new tag, use a descriptive name that clearly indicates the purpose or significance of the release.

• Share tags with team members: Once a tag is created, share it with your team members so they can easily access and collaborate on the tagged release.

• Collaborate on tagged releases: Encourage your team members to actively participate in the development and testing of tagged releases by providing feedback, reporting issues, and suggesting improvements.

Remember, effective collaboration is key to successful tagged releases in GitLab.
