Use case 1: List releases in a GitLab repository, limited to 30 items

Code:

glab release list

Motivation:
Listing releases in a GitLab repository is essential for teams to keep track of different versions of their software. It allows developers to quickly access previous releases and understand the project’s evolution. This functionality becomes especially useful when teams work on multiple concurrent projects or when onboarding new team members who need to familiarize themselves with the project’s history.

Explanation:

• glab: This is the CLI tool for GitLab, which allows for interaction with GitLab repositories from the command line.
• release: This command segment specifies that we are working with the release feature of a GitLab project.
• list: This part of the command tells glab to display a list of releases. By default, this list is limited to 30 entries to keep the output concise and manageable.

Example Output:

v2.0.1    - Jan 15, 2023    - Bug fixes and performance improvements
v2.0.0    - Jan 08, 2023    - Major release with new features
v1.5.0    - Dec 20, 2022    - Minor updates and enhancements
... (27 more)

Use case 2: Display information about a specific release

Code:

glab release view v2.0.1

Motivation:

Use case 4: Delete a specific release

Code:

glab release delete v1.0.0

Motivation:
Sometimes, a release may need to be removed, either due to critical errors found after the release or because it is superseded by other updates. This command helps maintain a clean project repository by removing outdated or erroneous releases, thereby preventing any confusion in the release management process.

Explanation:

• glab: The command-line tool for GitLab interactions.
• release: Refers to the GitLab releases a user is working with.

Use case 5: Download assets from a specific release

Code:

glab release download v2.0.1

Motivation:
Downloading assets associated with a specific release can be necessary for reviewing the exact files included in a release or for deploying them. It allows developers to access compiled binaries, documentation, or other related files conveniently from anywhere.

Explanation:

• glab: The GitLab command-line interface.
• release: Indicates working with releases in a project.
• download: Specifies the action to retrieve assets.
• v2.0.1: The release tag from which assets are to be downloaded, ensuring precise targeting of the file versions.

Use case 6: Upload assets to a specific release

Code:

glab release upload v2.1.0 path/to/file1 path/to/file2

Motivation:
Uploading files to a specific release is critical for ensuring that all necessary assets are available to users or developers who interact with the release. This command is particularly useful for adding documentation, binaries, or configuration files that complement the release’s code.

Explanation:

• glab: The tool for managing GitLab tasks via the terminal.
• release: Signifies that the task involves releases.
• upload: The operation to add new assets.
• v2.1.0: The release tag where the files will be uploaded.
• path/to/file1, path/to/file2: The paths of the files to be uploaded, allowing for multiple files to be specified and added simultaneously.

Example Output:

Uploading files to release v2.1.0...
