プッシュしてCI実行前に、ローカルで.gitlab-ci.ymlの検証(validation)したいよね。。。

1. gitlabのcli `glab` をインストール

brew install glab

2. `.gitlab-ci.yml` の構文チェックを実行

% glab ci lint
You must be in a GitLab project repository for this action.
Error: 1 error occurred:
	* kaihei777/sample-gitlab-project: 404 Not Found

3. `404 Not Found`になるので状況確認

glab の認証トークンが設定されていない

glab auth status

gitlab.com
  x gitlab.com: API call failed: GET https://gitlab.com/api/v4/user: 401 {message: 401 Unauthorized}
  ✓ Git operations for gitlab.com configured to use ssh protocol.
  ✓ API calls for gitlab.com are made over https protocol.
  ✓ REST API Endpoint: https://gitlab.com/api/v4/
  ✓ GraphQL Endpoint: https://gitlab.com/api/graphql/
  ! No token provided in configuration file.

x could not authenticate to one or more of the configured GitLab instances.

4. 未認証の場合は、以下の手順でトークンを設定

GitLab のアクセストークン発行ページにアクセス
Personal access tokensを追加
api スコープを持つアクセストークンを発行
glab auth login を実行し、発行したトークンを入力

api

glab auth login
? What GitLab instance do you want to log into? gitlab.com
- Logging into gitlab.com
? How would you like to sign in? Token

Tip: generate a personal access token at https://gitlab.com/-/user_settings/personal_access_tokens?scopes=api,write_repository.
The minimum required scopes are 'api' and 'write_repository'.
? Paste your authentication token: **************************
? Choose default Git protocol: SSH
- glab config set -h gitlab.com git_protocol ssh
✓ Configured Git protocol.
- glab config set -h gitlab.com api_protocol https
✓ Configured API protocol.
✓ Logged in as kaihei777
✓ Configuration saved to /Users/kaihei777/.config/glab-cli/config.yml

5. 再度、`.gitlab-ci.yml` の構文チェックを実行

glab ci lint    
Validating...
✓ CI/CD YAML is valid!
