It's a workaround until conclusion of https://gitlab.com/gitlab-org/gitlab/-/issues/17718, you can create manual jobs that will be started by this program.

Its proposal is to execute manual jobs inside a Gitlab group or project, so you can queue a manual job that will be started in a proper time by this program.

minimal docker image: ghcr.io/dyegomb/gitlabjob-executor:latest

Basically you have to feed the .env¹ file as example below.

private_token="XXXXXXXXXXXXX"
base_url="https://gitlab.com/"
project_id=123
group_id=1
production_tag_key="PROD_TAG" # Variable to look for in a pipeline
max_wait_time=1800 # Max waiting time for a job in seconds

[smtp]
server="mail.com"
user="user"
from="user@mail.com"
to="destination@mail.com"
subject="[Subject Prefix] "
pass="Secret"

It also supports definition from environment variables, whom takes precedence.

The SMTP section is only needed if you want to receive report emails. SMTP settings from environment variables must has SMTP_ prefix.
