- Set up Code Owners
- Groups as Code Owners
When a file matches multiple
Code Owners define who owns specific files or directories in a repository.
- The users you define as Code Owners are displayed in the UI when you browse directories.
- You can set your merge requests so they must be approved by Code Owners before merge.
- You can protect a branch and allow only Code Owners to approve changes to the branch.
If you don’t want to use Code Owners for approvals, you can configure rules instead.
You can use Code Owners to specify users or shared groups that are responsible for specific files and directories in a repository.
To set up Code Owners:
- Choose the location where you want to specify Code Owners:
- In the root directory of the repository
- In the
- In the
In that location, create a file named
In the file, enter text that follows one of these patterns:
# Code Owners for a file filename @username1 @username2 # Code Owners for a directory directoryname/ @username1 @username2 # All group members as Code Owners for a file filename @groupname # All group members as Code Owners for a directory directoryname/ @groupname
The Code Owners are now displayed in the UI. They apply to the current branch only.
You can use members of groups and subgroups as Code Owners for a project.
For example, if you have these groups:
Group X (
group-x) with Project A in it.
Subgroup Y (
group-x/subgroup-y), which belongs to Group X, with Project B in it.
The eligible Code Owners:
- For Project A are the members of Group X only, because Project A doesn’t belong to Subgroup Y.
- For Project B are the members of both Group X and Subgroup Y.
You can invite Subgroup Y to Project A so that their members also become eligible Code Owners.
If you do not invite Subgroup Y to Project A, but make them Code Owners, their approval of the merge request becomes optional.
To set a group as a Code Owner:
CODEOWNERS file, enter text that follows one of these patterns:
# All group members as Code Owners for a file file.md @group-x # All subgroup members as Code Owners for a file file.md @group-x/subgroup-y # All group and subgroup members as Code Owners for a file file.md @group-x @group-x/subgroup-y
When a file matches multiple entries in the
the users from last pattern matching the file are used.
For example, in the following
README.md @user1 # This line would also match the file README.md *.md @user2
The Code Owner for
README.md would be
If you use sections, the last user for each section is used.
Only one CODEOWNERS pattern can match per file path.
You can organize Code Owners by putting them into named sections.
You can use sections for shared directories, so that multiple teams can be reviewers.
To add a section to the
CODEOWNERS file, enter a section name in brackets,
followed by the files or directories, and users, groups, or subgroups:
[README Owners] README.md @user1 @user2 internal/README.md @user2
Each Code Owner in the merge request widget is listed under a label. The following image shows a Groups and Documentation section:
If multiple sections have the same name, they are combined. Also, section headings are not case-sensitive. For example:
[Documentation] ee/docs/ @docs docs/ @docs [Database] README.md @database model/db/ @database [DOCUMENTATION] README.md @docs
This code results in three entries under the Documentation section header, and two entries under Database. The entries defined under the sections Documentation and DOCUMENTATION are combined, using the case of the first section.
You can make a section optional, so that approval from the Code Owners in that section is optional.
Put a caret
^ character before the Code Owners section name. For example:
[Documentation] *.md @root [Ruby] *.rb @root ^[Go] *.go @root
The optional Code Owners section displays in merge requests under the Approval Rules area:
If a section is duplicated in the file, and one of them is marked as optional and the other isn’t, the section is required.
Optional sections in the
CODEOWNERS file are treated as optional only
when changes are submitted by using merge requests. If a change is submitted directly
to the protected branch, approval from Code Owners is still required, even if the
section is marked as optional. An issue exists
to allow direct pushes to the protected branch for sections marked as optional.
# This is an example of a CODEOWNERS file. # Lines that start with `#` are ignored. # app/ @commented-rule # Specify a default Code Owner by using a wildcard: * @default-codeowner # Specify multiple Code Owners by using a tab or space: * @multiple @code @owners # Rules defined later in the file take precedence over the rules # defined before. # For example, for all files with a filename ending in `.rb`: *.rb @ruby-owner # Files with a `#` can still be accessed by escaping the pound sign: \#file_with_pound.rb @owner-file-with-pound # Specify multiple Code Owners separated by spaces or tabs. # In the following case the CODEOWNERS file from the root of the repo # has 3 Code Owners (@multiple @code @owners): CODEOWNERS @multiple @code @owners # You can use both usernames or email addresses to match # users. Everything else is ignored. For example, this code # specifies the `@legal` and a user with email `email@example.com` as the # owner for the LICENSE file: LICENSE @legal this_does_not_match firstname.lastname@example.org # Use group names to match groups, and nested groups to specify # them as owners for a file: README @group @group/with-nested/subgroup # End a path in a `/` to specify the Code Owners for every file # nested in that directory, on any level: /docs/ @all-docs # End a path in `/*` to specify Code Owners for every file in # a directory, but not nested deeper. This code matches # `docs/index.md` but not `docs/projects/index.md`: /docs/* @root-docs # This code makes matches a `lib` directory nested anywhere in the repository: lib/ @lib-owner # This code match only a `config` directory in the root of the repository: /config/ @config-owner # If the path contains spaces, escape them like this: path\ with\ spaces/ @space-owner # Code Owners section: [Documentation] ee/docs @docs docs @docs [Database] README.md @database model/db @database # This section is combined with the previously defined [Documentation] section: [DOCUMENTATION] README.md @docs
