Remove artifacts from CI manually

According to the documentation, deleting the entire job log (click on the trash can) will also delete the artifacts.

Building on top of @David 's answer, @Philipp pointed out that there is now an api endpoint to delete only the job artifacts instead of the entire job.

You can run this script directly in the console, or use node-fetch to run in node.js.

//Go to: https://gitlab.com/profile/personal_access_tokens
const API_KEY = "API_KEY";

//You can find project id inside the "General project settings" tab
const PROJECT_ID = 12345678;
const PROJECT_URL = "https://gitlab.com/api/v4/projects/" + PROJECT_ID + "/"

let jobs = [];
for(let i = 0, currentJobs = []; i == 0 || currentJobs.length > 0; i++){
    currentJobs = await sendApiRequest(
        PROJECT_URL + "jobs/?per_page=100&page=" + (i + 1)
    ).then(e => e.json());
    jobs = jobs.concat(currentJobs);
}

//skip jobs without artifacts
jobs = jobs.filter(e => e.artifacts);

//keep the latest build.
jobs.shift();

for(let job of jobs)
    await sendApiRequest(
        PROJECT_URL + "jobs/" + job.id + "/artifacts",
        {method: "DELETE"}
    );

async function sendApiRequest(url, options = {}){
    if(!options.headers)
        options.headers = {};
    options.headers["PRIVATE-TOKEN"] = API_KEY;

    return fetch(url, options);
}

You can use the GitLab REST API to delete the artifacts from the jobs if you don't have direct access to the server. Here's a sample curl script that uses the API:

#!/bin/bash
    
# project_id, find it here: https://gitlab.com/[organization name]/[repository name]/edit inside the "General project settings" tab
project_id="3034900"
    
# token, find it here: https://gitlab.com/profile/personal_access_tokens
token="Lifg_azxDyRp8eyNFRfg"
server="gitlab.com"
    
# go to https://gitlab.com/[organization name]/[repository name]/-/jobs
# then open JavaScript console
# copy/paste => copy(_.uniq($('.ci-status').map((x, e) => /([0-9]+)/.exec(e.href)).toArray()).join(' '))
# press enter, and then copy the result here :
# repeat for every page you want
job_ids=(48875658 48874137 48873496 48872419)
    
for job_id in ${job_ids[@]}
do
     URL="https://$server/api/v4/projects/$project_id/jobs/$job_id/erase"
     echo "$URL"
     curl --request POST --header "PRIVATE-TOKEN:${token}" "$URL"
     echo "\n"
done

An API call should be easier to script, with GitLab 14.7 (January 2022), which now offers:

Bulk delete artifacts with the API

While a good strategy for managing storage consumption is to set regular expiration policies for artifacts, sometimes you need to reduce items in storage right away.

Previously, you might have used a script to automate the tedious task of deleting artifacts one by one with API calls, but now you can use a new API endpoint to bulk delete job artifacts quickly and easily.

See Documentation, Issue 223793 and Merge Request 75488.

 curl --request DELETE --header "PRIVATE-TOKEN: <your_access_token>" \
      "https://gitlab.example.com/api/v4/projects/1/artifacts"
