Docker Compose periodic task schedulers

I have found a couple of very, very interesting of periodic task schedulers which integrate well with docker compose: ofelia and compose-scheduler (whose author got inspired on ofelia).

Ofelia examples

See both docker-compose.ofelia.as_service.yml and docker-compose.ofelia.as_run.yml.

Compose-scheduler examples

See both docker-compose.compose-scheduler.as_exec.yml and docker-compose.compose-scheduler.as_run.yml.

docker-compose.compose-scheduler.as_exec.yml

services:
  scheduler:
    image: ghcr.io/reddec/compose-scheduler:1.1.0
    depends_on:
      - tocata
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

  tocata:
    image: alpine:latest
    command: ["sh", "-c", "while true ; do sleep 10; done"]
    volumes:
      - ./COLODRILLO:/COLODRILLO:Z
    labels:
      net.reddec.scheduler.cron: "@every 5s"
      net.reddec.scheduler.exec: "sh -c 'echo $(date -Is) >> /COLODRILLO/jarl-reddec.txt'"

docker-compose.compose-scheduler.as_run.yml

services:
  scheduler:
    image: ghcr.io/reddec/compose-scheduler:1.1.0
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

  date:
    image: alpine:latest
    restart: "no"
    command: ["sh","-c","sleep 10 ; echo $(date -Is) >> /COLODRILLO/jarl-reddec2.txt"]
    volumes:
      - ./COLODRILLO:/COLODRILLO:Z
    labels:
      - "net.reddec.scheduler.cron=@every 5s"

docker-compose.ofelia.as_run.yml

version: "3"
services:
  ofelia:
    image: mcuadros/ofelia:latest
    command: daemon --docker -f label=com.docker.compose.project=${COMPOSE_PROJECT_NAME}
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
    labels:
      ofelia.job-local.my-test-job.schedule: "@every 5s"
      ofelia.job-local.my-test-job.command: "date"
      ofelia.job-run.tocata2.schedule: "@every 5s"
      ofelia.job-run.tocata2.image: alpine:latest
      ofelia.job-run.tocata2.command: "sh -c 'sleep 10 ; echo $(date -Is) >> /COLODRILLO/jarl.txt'"
      ofelia.job-run.tocata2.volume: /home/jmfernandez/TEST/ofelia-test/COLODRILLO:/COLODRILLO:Z
      ofelia.job-run.tocata2.no-overlap: "true"

docker-compose.ofelia.as_service.yml

version: "3"
services:
  ofelia:
    image: mcuadros/ofelia:latest
    depends_on:
      - tocata
    command: daemon --docker -f label=com.docker.compose.project=${COMPOSE_PROJECT_NAME}
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
    labels:
      ofelia.job-local.my-test-job.schedule: "@every 5s"
      ofelia.job-local.my-test-job.command: "date"

  tocata:
    image: alpine:latest
    command: ["sh", "-c", "while true ; do sleep 10; done"]
    volumes:
      - ./COLODRILLO:/COLODRILLO:Z
    labels:
      ofelia.enabled: "true"
      ofelia.job-exec.datecron.schedule: "@every 5s"
      ofelia.job-exec.datecron.command: "sh -c 'echo $(date -Is) >> /COLODRILLO/jarl.txt'"
