Code Owners (STARTER)
- Introduced in GitLab Starter 11.3.
- Support for group namespaces added in GitLab Starter 12.1.
- Code Owners for Merge Request approvals was introduced in GitLab Premium 11.9.
You can use a CODEOWNERS file to specify users or
shared groups
that are responsible for certain files in a repository.
You can choose and add the CODEOWNERS file in three places:
- To the root directory of the repository
- Inside the
.gitlab/directory - Inside the
docs/directory
The CODEOWNERS file is scoped to a branch, which means that with the
introduction of new files, the person adding the new content can
specify themselves as a code owner, all before the new changes
get merged to the default branch.
When a file matches multiple entries in the CODEOWNERS file,
the users from all entries are displayed on the blob page of
the given file.
Approvals by Code Owners
Once you've set Code Owners to a project, you can configure it to receive approvals:
- As merge request eligible approvers. (STARTER)
- As required approvers for protected branches. (PREMIUM)
Once set, Code Owners are displayed in merge requests widgets:
The syntax of Code Owners files
Files can be specified using the same kind of patterns you would use
in the .gitignore file followed by the @username or email of one
or more users or by the @name of one or more groups that should
be owners of the file.
The order in which the paths are defined is significant: the last pattern that matches a given path will be used to find the code owners.
Starting a line with a # indicates a comment. This needs to be
escaped using \# to address files for which the name starts with a
#.
Example CODEOWNERS file:
# This is an example code owners file, lines starting with a `#` will
# be ignored.
# app/ @commented-rule
# We can specify a default match using wildcards:
* @default-codeowner
# Rules defined later in the file take precedence over the rules
# defined before.
# This will match all files for which the file name ends in `.rb`
*.rb @ruby-owner
# Files with a `#` can still be accesssed by escaping the pound sign
\#file_with_pound.rb @owner-file-with-pound
# Multiple codeowners can be specified, separated by spaces or tabs
CODEOWNERS @multiple @code @owners
# Both usernames or email addresses can be used to match
# users. Everything else will be ignored. For example this will
# specify `@legal` and a user with email `janedoe@gitlab.com` as the
# owner for the LICENSE file
LICENSE @legal this_does_not_match janedoe@gitlab.com
# Group names can be used to match groups and nested groups to specify
# them as owners for a file
README @group @group/with-nested/subgroup
# Ending a path in a `/` will specify the code owners for every file
# nested in that directory, on any level
/docs/ @all-docs
# Ending a path in `/*` will specify code owners for every file in
# that directory, but not nested deeper. This will match
# `docs/index.md` but not `docs/projects/index.md`
/docs/* @root-docs
# This will make a `lib` directory nested anywhere in the repository
# match
lib/ @lib-owner
# This will only match a `config` directory in the root of the
# repository
/config/ @config-owner
# If the path contains spaces, these need to be escaped like this:
path\ with\ spaces/ @space-owner
