Download the latest artifacts of failed gitlab pipeline

Is there some way to download the artifacts from the latest job run (without knowing the job ID), independent of its outcome?

In order to achieve this we will use the Gitlab API in combination with the jq package.

Let's break down this question into components.

Firstly, we need to find out the id of the last executed pipeline for this project. https://docs.gitlab.com/ee/api/pipelines.html#list-project-pipelines

GET /projects/:id/pipelines

For this call you will need your access token, if you don't have one already check https://docs.gitlab.com/ee/user/profile/personal_access_tokens.html#create-a-personal-access-token https://docs.gitlab.com/ee/user/project/settings/project_access_tokens.html#create-a-project-access-token

You will also need the Project ID

LAST_PIPELINE_ID=$(curl -s --header "PRIVATE-TOKEN: <access_token>" https://gitlab.com/api/v4/projects/<project_id>/pipelines | jq '.[0].id')

Next we will retrieve the job id by providing the job name by using the following API https://docs.gitlab.com/ee/api/jobs.html#list-pipeline-jobs

GET /projects/:id/pipelines/:pipeline_id/jobs

In your case you need to change the following example with your job's name, in this example let's call it my_job

JOB_ID=$(curl -s --header "PRIVATE-TOKEN: <access_token>" https://gitlab.com/api/v4/projects/<project_id>/pipelines/$LAST_PIPELINE_ID/jobs | jq '.[] | select(.name=="my_job") | .id')

Now we are ready to actually retrieve the artifacts, with the following API

GET /projects/:id/jobs/:job_id/artifacts

https://docs.gitlab.com/ee/api/job_artifacts.html#get-job-artifacts

wget -U "Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.17 (KHTML,like Gecko) Ubuntu/11.04 Chromium/11.0.654.0 Chrome/11.0.654.0 Safari/534.17" --header "PRIVATE-TOKEN: <access_token>" "https://gitlab.com/api/v4/projects/<project_id>/jobs/$JOB_ID/artifacts" -O artifacts.zip

The artifacts are available as artifacts.zip in the folder you executed wget from

Combining them here for clarity

LAST_PIPELINE_ID=$(curl -s --header "PRIVATE-TOKEN: <access_token>" https://gitlab.com/api/v4/projects/<project_id>/pipelines | jq '.[0].id')
JOB_ID=$(curl -s --header "PRIVATE-TOKEN: <access_token>" https://gitlab.com/api/v4/projects/<project_id>/pipelines/$LAST_PIPELINE_ID/jobs | jq '.[] | select(.name=="my_job") | .id')
wget -U "Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.17 (KHTML,like Gecko) Ubuntu/11.04 Chromium/11.0.654.0 Chrome/11.0.654.0 Safari/534.17" --header "PRIVATE-TOKEN: <access_token>" "https://gitlab.com/api/v4/projects/<project_id>/jobs/$JOB_ID/artifacts" -O artifacts.zip
