The following checks are enabled by default:
| Name | Description |
|---|---|
| duppatterns | [Duplicated Pattern Checker] Reports if CODEOWNERS file contain duplicated lines with the same file pattern. |
| files | [File Exist Checker] Reports if CODEOWNERS file contain lines with the file pattern that do not exist in a given repository. |
| owners | [Valid Owner Checker] Reports if CODEOWNERS file contain invalid owners definition. Allowed owner syntax: @username, @org/team-name or user@example.com source: https://help.github.com/articles/about-code-owners/#codeowners-syntax. Checks: 1. Check if the owner's definition is valid (is either a GitHub user name, an organization team name or an email address). 2. Check if a GitHub owner has a GitHub account 3. Check if a GitHub owner is in a given organization 4. Check if an organization team exists |
| syntax | [Valid Syntax Checker] Reports if CODEOWNERS file contain invalid syntax definition. It is imported as: "If any line in your CODEOWNERS file contains invalid syntax, the file will not be detected and will not be used to request reviews. Invalid syntax includes inline comments and user or team names that do not exist on GitHub." source: https://help.github.com/articles/about-code-owners/#codeowners-syntax. |
The experimental checks are disabled by default:
| Name | Description |
|---|---|
| notowned | [Not Owned File Checker] Reports if a given repository contain files that do not have specified owners in CODEOWNERS file. |
| avoid-shadowing | [Avoid Shadowing Checker] Reports if entries go from least specific to most specific. Otherwise, earlier entries are completely ignored. For example: # First entry/build/logs/ @octocat # Shadows * @s1 /b*/logs @s5 # OK /b*/other @o1 /script/* @o2 |
To enable experimental check set EXPERIMENTAL_CHECKS=notowned environment variable.
Check the Configuration section for more info on how to enable and configure given checks.
Use the following environment variables to configure the application:
| Name | Default | Description |
|---|---|---|
| REPOSITORY_PATH * | Path to your repository on your local machine. | |
| GITHUB_ACCESS_TOKEN | GitHub access token. Instruction for creating a token can be found here. If not provided, the owners validating functionality may not work properly. For example, you may reach the API calls quota or, if you are setting GitHub Enterprise base URL, an unauthorized error may occur. | |
| GITHUB_BASE_URL | https://api.github.com/ |
GitHub base URL for API requests. Defaults to the public GitHub API but can be set to a domain endpoint to use with GitHub Enterprise. |
| GITHUB_UPLOAD_URL | https://uploads.github.com/ |
GitHub upload URL for uploading files. It is taken into account only when GITHUB_BASE_URL is also set. If only GITHUB_BASE_URL is provided, this parameter defaults to the GITHUB_BASE_URL value. |
| GITHUB_APP_ID | Github App ID for authentication. This replaces the GITHUB_ACCESS_TOKEN. Instruction for creating a Github App can be found here |
|
| GITHUB_APP_INSTALLATION_ID | Github App Installation ID. Required when GITHUB_APP_ID is set. |
|
| GITHUB_APP_PRIVATE_KEY | Github App private key in PEM format. Required when GITHUB_APP_ID is set. |
|
| CHECKS | List of checks to be executed. By default, all checks are executed. Possible values: files,owners,duppatterns,syntax. |
|
| EXPERIMENTAL_CHECKS | The comma-separated list of experimental checks that should be executed. By default, all experimental checks are turned off. Possible values: notowned. |
|
| CHECK_FAILURE_LEVEL | warning |
Defines the level on which the application should treat check issues as failures. Defaults to warning, which treats both errors and warnings as failures, and exits with error code 3. Possible values are error and warning. |
| OWNER_CHECKER_REPOSITORY * | The owner and repository name separated by slash. For example, gh-codeowners/codeowners-samples. Used to check if GitHub owner is in the given organization. | |
| OWNER_CHECKER_IGNORED_OWNERS | @ghost |
The comma-separated list of owners that should not be validated. Example: "@owner1,@owner2,@org/team1,example@email.com". |
| OWNER_CHECKER_ALLOW_UNOWNED_PATTERNS | true |
Specifies whether CODEOWNERS may have unowned files. For example: /infra/oncall-rotator/ @sre-team /infra/oncall-rotator/oncall-config.yml The /infra/oncall-rotator/oncall-config.yml file is not owned by anyone. |
| OWNER_CHECKER_OWNERS_MUST_BE_TEAMS | false |
Specifies whether only teams are allowed as owners of files. |
| NOT_OWNED_CHECKER_SKIP_PATTERNS | The comma-separated list of patterns that should be ignored by not-owned-checker. For example, you can specify * and as a result, the * pattern from the CODEOWNERS file will be ignored and files owned by this pattern will be reported as unowned unless a later specific pattern will match that path. It's useful because often we have default owners entry at the begging of the CODOEWNERS file, e.g. * @global-owner1 @global-owner2 |
|
| NOT_OWNED_CHECKER_SUBDIRECTORIES | The comma-separated list of subdirectories to check in not-owned-checker. When specified, only files in the listed subdirectories will be checked if they do not have specified owners in CODEOWNERS. |
|
| NOT_OWNED_CHECKER_TRUST_WORKSPACE | false |
Specifies whether the repository path should be marked as safe. See: actions/checkout#766. |
* - Required
Application exits with different status codes which allow you to easily distinguish between error categories.
| Code | Description |
|---|---|
| 1 | The application startup failed due to the wrong configuration or internal error. |
| 2 | The application was closed because the OS sends a termination signal (SIGINT or SIGTERM). |
| 3 | The CODEOWNERS validation failed - executed checks found some issues. |
