docker_cron

I have this voice in my head. When I create, it highlights things I should be cautious of using. It is on high alert when some dependency relies on external servers; external servers that could go dark at any moment. Or when I consider something hacky that will fall apart too soon. Or in those situations I feel too smart and come up with too clever a solution when. That voice is basically the gegenspieler of not simple enough things.

The below article is about when to quell that voice.

The other day I set up Renovate, a bot that continuously scans my code for outdated dependencies. I chose to deploy it via Docker. Then the problem arose of starting Renovate at regular intervals.

services:
  Renovate:
    image: "{{ docker_forgejo_renovate_image }}"
    volumes:
      - "{{ docker_forgejo_dir }}/entrypoint.sh:/usr/src/app/entrypoint.sh"
      - "{{ docker_forgejo_dir }}/config.js:/usr/src/app/config.js"
    environment:
      - "CRON_TIME={{ docker_forgejo_renovate_cron }}"
      - GITHUB_COM_TOKEN={{ docker_forgejo_github_token }}
      - RENOVATE_TOKEN={{ docker_forgejo_codeberg_token }}
      - LOG_LEVEL=debug
    entrypoint: /usr/src/app/entrypoint.sh
    restart: "unless-stopped"

#!/bin/bash

trap 'renovate' HUP
echo sleeping and waiting for HUP to launch renovate
while :; do
    sleep 10 & wait ${!}
done
