Configure pull mirroring for a project

Field mirror_branch_regex introduced in GitLab 15.8 with a flag named mirror_only_branches_match_regex. Disabled by default.

Enabled by default in GitLab 16.0.

Generally available in GitLab 16.2. Feature flag mirror_only_branches_match_regex removed.

Configure pull mirroring while creating a new project or updating an existing project by using the API if the remote repository is accessible publicly or by using username:token authentication.

If your HTTP repository is not publicly accessible, you can add the authentication information to the URL. For example, https://username:token@gitlab.company.com/group/project.git where token is a personal access token with the api scope enabled.

Supported attributes:

Attribute	Type	Required	Description
`import_url`	string	Yes	URL of remote repository being mirrored (with `user:token` if needed).
`mirror`	boolean	Yes	Enables pull mirroring on project when set to `true`.
`mirror_trigger_builds`	boolean	No	Trigger pipelines for mirror updates when set to `true`.
`only_mirror_protected_branches`	boolean	No	Limits mirroring to only protected branches when set to `true`.
`mirror_branch_regex`	String	No	Contains a regular expression. Only branches with names matching the regex are mirrored. Requires `only_mirror_protected_branches` to be disabled.

Example creating a project with pull mirroring:

curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" \
 --header "Content-Type: application/json" \
 --data '{
  "name": "new_project",
  "namespace_id": "1",
  "mirror": true,
  "import_url": "https://username:token@gitlab.example.com/group/project.git"
 }' \
 --url "https://gitlab.example.com/api/v4/projects/"

Example adding pull mirroring:

curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" \
 --url "https://gitlab.example.com/api/v4/projects/:id" \
 --data "mirror=true&import_url=https://username:token@gitlab.example.com/group/project.git"

Example removing pull mirroring:

curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" \
 --url "https://gitlab.example.com/api/v4/projects/:id"  \
 --data "mirror=false"
