"artifacts_file" worked for me, but it's trivial to support both, I also tweaked the output so you can see what job failed if any, and made it start at the first page:

#!/usr/bin/env python3

import time

import requests

project_id = '...'
token = '...'
server = 'gitlab.com'
start_page = 1

print("Creating list of all jobs that currently have artifacts...")
# We skip the first page.
url = f"https://{server}/api/v4/projects/{project_id}/jobs?per_page=100&page={start_page}"
while url:
    print(f"Processing page: {url}")
    response = requests.get(
        url,
        headers={
            'private-token': token,
        },
    )

    if response.status_code in [500, 429]:
        print(f"Status {response.status_code}, retrying.")
        time.sleep(10)
        continue

    response.raise_for_status()
    response_json = response.json()
    for job in response_json:
        if job.get('artifacts_file', None) or job.get('artifacts', None):
            job_id = job['id']
            print(f"Processing job ID: {job_id}", end="")
            delete_response = requests.delete(
                f"https://{server}/api/v4/projects/{project_id}/jobs/{job_id}/artifacts",
                headers={
                    'private-token': token,
                },
            )
            print(f" - status: {delete_response.status_code}")

    url = response.links.get('next', {}).get('url', None)

While the script deletes jobs' artifacts, you can also delete project's artifacts by adding this code:

url = f"https://{server}/api/v4/projects/{project_id}/artifacts"
delete_response = requests.delete(
    url,
    headers={
        'private-token': token,
    }
)
print(f" - status: {delete_response.status_code}")

This does not work if you're project has more than 10000 jobs, due to the removal of X-Total-Pages header from the Gitlab API responses.

Yes, I just found out that the X-Total-Pages header is now missing for performance reasons. Fortunately when a page number is too high, an empty json list ([]) is returned so it is quite easy to use a loop such as (here in bash):

PER_PAGE=100
PAGE=1
while JOBS=$(curl -s --header "PRIVATE-TOKEN: $TOKEN" "$GITLAB_INSTANCE/$PROJECT_ID/jobs?per_page=$PER_PAGE&page=$PAGE&sort=asc") && [ "$JOBS" != "[]" ]
do
   for JOB in $(echo $JOBS | jq .[].id)
   do
      [...]
   done
   PAGE=$((PAGE+1))
done

Here's my slightly improved version for the 'do it in python' section (ignores job.log files which seem to be non-deletable, uses command line arguments to load the settings):

#!/usr/bin/env python3

import time
import requests
import sys

server = sys.argv[1]
project_id = sys.argv[2]
token = sys.argv[3]
start_page = sys.argv[4]

print("Creating list of all jobs that currently have artifacts...")
# We skip the first page.
url = f"https://{server}/api/v4/projects/{project_id}/jobs?per_page=100&page={start_page}"
while url:
    print(f"Processing page: {url}")
    response = requests.get(
        url,
        headers={
            'private-token': token,
        },
    )

    if response.status_code in [500, 429]:
        print(f"Status {response.status_code}, retrying.")
        time.sleep(10)
        continue

    response.raise_for_status()
    response_json = response.json()
    for job in response_json:
        artifacts = job.get('artifacts_file', None)
        if not artifacts:
            artifacts = job.get('artifacts', None)

        has_artifacts = False
        for artifact in artifacts:
            if artifact['filename'] != 'job.log':
                has_artifacts = True
                break

        if has_artifacts:
            job_id = job['id']
            print(f"Processing job ID: {job_id}", end="")
            delete_response = requests.delete(
                f"https://{server}/api/v4/projects/{project_id}/jobs/{job_id}/artifacts",
                headers={
                    'private-token': token,
                },
            )
            print(f" - status: {delete_response.status_code}")

    url = response.links.get('next', {}).get('url', None)

I get this error:

       ~~~~~~~~^^^^^^^^^^^^
TypeError: string indices must be integers, not 'str'

@Tim-Schwalbe: Apologies, yes, I overlooked this case. I have amended the script to ignore artifacts_file, as this file seems to be contained in artifacts anyway.

I have improved my version a bit, it now automatically selects expired artifacts for deletion that (in my opinion) should be deleted in the first place, because they belong to jobs that were run on:

• merge requests that have been merged or closed;
• branches that have been merged.

It will also take a list of project ids as the last argument, making it easy to use in a cron job: Usage: {sys.argv[0]} <server> <token> <project id>...

@mikeller I suggest you write your script code in a gist, or even fork this one here and replace it with you python code =)

Each gist indicates which forks have activity, making it easy to find interesting changes from others.

@voiski: Good point, done: https://gist.github.com/mikeller/ee7a668a83e4b9bc61646bddb4a2ade6

New version that takes a GitLab group id as a parameter and then cleans up all repositories in the group: https://gist.github.com/mikeller/7034d99bc27c361fc6a2df84e19c36ff
