Remove Previous GitLab Pipelines from a project

So you build a GitLab project, you created a pipeline and then a scheduler to run every week your pipeline.

And then you realize that you are polluting the internet with deprecated (garbage) things, at some point you have a debug option on, bla bla bla… etc etc.

It is time to clean up your mess!

Create a GitLab API Token

aka Personal Access Tokens

Select scopes: api.

Verify API token

run something like this

export GITLAB_API="glpat-HldkXzyurwBmroAdQCMo"

curl -sL --header "PRIVATE-TOKEN: ${GITLAB_API}" "https://gitlab.com/api/v4/projects?owned=true" | jq .[].path_with_namespace

you should see your projects.

Get your Project ID

create a new bash variable:

export PROJECT="terraform-provider/terraform-provider-hcloud-ci"

and then use the get rest api call

curl -sL --header "PRIVATE-TOKEN: ${GITLAB_API}" "https://gitlab.com/api/v4/projects?owned=true&search=${PROJECT}&search_namespaces=true" | jq -r .[].id

or you can also put the id into a new bash variable:

export ID=$(curl -sL --header "PRIVATE-TOKEN: ${GITLAB_API}" "https://gitlab.com/api/v4/projects?owned=true&search=${PROJECT}&search_namespaces=true" | jq -r .[].id)

View the previous pipelines

curl -sL \
  --header "PRIVATE-TOKEN: ${GITLAB_API}" \
  https://gitlab.com/api/v4/projects/${ID}/pipelines | jq .

Remove deprecated pipelines

just delete them via the API

curl -sL --header "PRIVATE-TOKEN: ${GITLAB_API}"   "https://gitlab.com/api/v4/projects/${ID}/pipelines?per_page=150"  \
 | jq  -r .[].id    \
 | awk '{print "curl -sL --header \"PRIVATE-TOKEN: ${GITLAB_API}\" --request DELETE https://gitlab.com/api/v4/projects/${ID}/pipelines/"$1}'   \
 | sh -x

that’s it !
