Where to get the repository id for the repositories in Gitlab?

Question

I am using Gitlab integrated with Mantis BT All the required plugins are installed and configured

In Mantis BT, Repositories -> Action -> Manage, for the required the project click on Update Repository, in that we have a field called Gitlab Repository ID.
for that project. When I provided some numbers and updated them repository, the result in the change sets is changed but files and issues fields values are not getting updated.

Issues:

• How to get the repository id for the particular project in the gitlab?
• What is the problem for files and issues values for not getting changed?
  Need any configuration changes?

Answer 1

The mantis documentation states:

hub_repoid: id of the Gitlab projet, starting from 1 for the first created project (auto-filed if reponame is valid and readable for the user)

You could use the GitLab API to get that id

GET /projects/NAMESPACE/PROJECT_NAME

curl --header "PRIVATE-TOKEN: <yourPrivateToken>" https://gitlab.example.com/api/v3/projects/NAMESPACE/PROJECT_NAME

The answer includes its id:

{
  "id": 3,
  "description": null,
  "default_branch": "master",
  "public": false,
  "visibility_level": 0,
  ...

Answer 2

In the gitlab you have to navigate to the api exposed by GitLab to retrieve the required details.

First of all, you need the project_id for your project. This is exposed via CI_PROJECT_ID variable by GitLab. From the UI, navigate to the project and you would see the project id below the project name.

Once you have the project id then access the following url

https://gitlab.example.com/api/v4/projects/projectId/registry/repositories

this will give you a json response showing all repositories under the project. And you find the id from the response.

[{"id":876,"name":"","path":"group-name/subgroup-name/project-name","project_id":4099,"location":"registry.gitlab.example.com/group-name/subgroup-name/project-name","created_at":"2022-01-06T12:39:28.326Z","cleanup_policy_started_at":null}]

Now using this ID, you can further navigate to the API to fetch more details like container image tags.

for e.g.

https://gitlab.example.com/api/v4/projects/**4099**/registry/repositories/**876**/tags

or more specifically any particular tag

https://gitlab.exmaple.com/api/v4/projects/**4099**/registry/repositories/**876**/tags/**tagName**

Instead of accessing these from browser, it can be accessed from .gitlab-ci.yml as well.

for e.g. below is sample script for deleting a image tag from container registery.

curl --request DELETE --header "PRIVATE-TOKEN: <your_access_token>" \
     "https://gitlab.example.com/api/v4/projects/5/registry/repositories/2/tags/v10.0.0"
