gitlab_lint

This is a CLI application to quickly lint .gitlab-ci.yml files using the gitlab api. This can easily be added as a pre-commit step to locally catch any issues with your configuration prior to pushing your changes.

Installation

python3 -m pip install -U gitlab_lint

Configuration

You can set the following environmental variables:

GITLAB_LINT_DOMAIN - Which allows you to override the default gitlab.com domain, and point at a local instance

GITLAB_LINT_TOKEN - If your .gitlab-ci.yml contains any includes, you may need to set a private token to pull data from those other repos

GITLAB_LINT_PROJECT - If your .gitlab-ci.yml contains any includes which source from your local repo, you may set your project ID. If your repo is private, you must set your token as well.

GITLAB_LINT_PATH - If you're linting anything other than the default .gitlab-ci.yml file.

GITLAB_LINT_VERIFY - If you prefer TLS checking

I would recommend adding these to your ~/.profile or ~/.bash_profile

Parameters

Flag	Description	Type	Default	Required
--domain	Gitlab Domain. You can set envvar GITLAB_LINT_DOMAIN	string	gitlab.com	no
--project	Gitlab Project ID. You can set envvar GITLAB_LINT_PROJECT	string	None	no
--token	Gitlab Personal Token. You can set envvar GITLAB_LINT_TOKEN	string	None	no
--path	Path to .gitlab-ci.yml, defaults to local directory. You can set envvar GITLAB_LINT_PATH	string	.gitlab-ci.yml	no
--verify	Enables HTTPS verification, which is disabled by default to support privately hosted instances. You can set envvar GITLAB_LINT_VERIFY	Flag	False	no

Example Usage

If your .gitlab-ci.yml is in the current directory it is as easy as:

$ gll
GitLab CI configuration is valid

Failures will appear like so:

$ gll
GitLab CI configuration is invalid
(<unknown>): could not find expected ':' while scanning a simple key at line 26 column 1

If you need to you can specify the path:

$ gll --path path/to/.gitlab-ci.yml
GitLab CI configuration is valid

If you choose not to set the envvars for domain and token you can pass them in as flags:

$ gll --path path/to/.gitlab-ci.yml --domain gitlab.mycompany.com --project 1234 --token <gitlab personal token>
GitLab CI configuration is valid

Https verification is disabled by default to support privately hosted instances, if you would like to enable pass the --verify | -v flag

$ gll --verify
GitLab CI configuration is valid
