Validate and lint your gitlab ci files using ShellCheck, the Gitlab API, curated checks or even build your own checks

Features

• ShellCheck for scripts
• Validation against Pipeline Lint API for project
• Curated checks for common mistakes (feel free to contribute new ones)
• Automatic detection of the current gitlab project with an option to overwrite
• Available as pre-commit hook
• Usable to valid dynamically generated pipelines using the python wrapper
• Support for gitlab.com and self-hosted instances
• Support for custom policies written in Rego
• Resolve and validate includes (how it works and limitations)

Installation

Motivation

Unfortunately, GitLab didn't provide a tool to validate CI configuration for quite a while. Now that changed with the glab CLI providing glab ci lint but it is quite limited and under the hood just calls the new CI Lint API.

Throughout the years quite some tools evolved, but most of them are either outdated, painful to use or install, and basically also provide the lint functionality from the API.

As most of the logic in pipelines is written in shell scripts via the *script attributes these are lacking completely from all tools out there as well as the official lint API.

The goal of gitlab-ci-verify is to provide the stock CI Lint functionality plus shellcheck. Completed in the future some rules to lint that common patterns are working as intended by GitLab and void them from being pushed and leading to unexpected behavior.

Credits

This whole project wouldn't be possible with the great work of the following libraries/tools:

• Shellcheck by koalaman
• go stdlib
• pflag by spf13
• go-yaml, which I forked to timo-reymann/go-yaml
