Configure pull mirroring for a project

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"
