Scheduling netbox-sync container

[AxisNL]

Hey, this is not as much a real issue, more a request to append documentation (to compensate for my lack of experience, probably).

I've been running netbox in docker for quote a while (running on a host with portainer as an easy management interface), and I now added the netbox-sync container and configured it. It works like a charm!

I appended the netbox-sync container to the netbox docker-compose file, which keeps everything running. But now netbox-sync keeps on running of course. It goes off and finishes in 45 seconds, then starts again, and again, and again, etc.

Now I know this is probably not how the sync container is meant to be run, but I would love the netbox-sync container to get an option to for example sleep 3600 seconds after every run, just to name an example? This way, I could have portainer/compose just keep the containers running and happy, and the sync would run regularly.

Or are there other ways to have a single docker compose file and to run this netbox-sync container on fixed intervals with a cron-like syntax or something?

Hi,

A quick and dirty solution would be adding a '&&', 'sleep', '3600' to the cmd line in docker-compose. have you tried that?

[AxisNL]

Well, I was not able to get any combination of entrypoint of cmd to work, python doesn't like that syntax:

netbox-sync  | usage: netbox-sync.py [-h] [-c settings.ini [settings.ini ...]] [-g]
netbox-sync  |                       [-l {DEBUG3,DEBUG2,DEBUG,INFO,WARNING,ERROR}] [-n] [-p]
netbox-sync  | netbox-sync.py: error: unrecognized arguments: && sleep 3600

But I was able to create a script, mount that into the container and set it as entrypoint:

#puppet code
  file { '/data/volumes/netbox-sync/start_with_sleep.sh':
    ensure  => present,
    mode    => '0700',
    owner   => 1000,
    group   => 1000,
    content => '#!/bin/sh
python3 netbox-sync.py; sleep 3600',
    require => File['/data/volumes/netbox-sync']
  }

and in docker-compose:

  [..]
  netbox-sync:
    container_name: netbox-sync
    image: registry.company.local/dockerhub-proxy/bbricardo/netbox-sync
    restart: always
    entrypoint: ['/app/start_with_sleep.sh']
    volumes:
      - "/data/volumes/netbox-sync/start_with_sleep.sh:/app/start_with_sleep.sh:ro"
    environment:
[..]

So I'm happy! But would still like a more native approach ;)

I'm doing it like this:

  netbox-sync:
    image: bbricardo/netbox-sync:latest
    volumes:
      - ./netbox-sync/settings.ini:/app/settings.ini
    entrypoint: [ "sh", "-c" ]
    command: >
      "while true; do
         echo '[INFO] Running netbox-sync at $(date)';
         python3 netbox-sync.py -c settings.ini;
         echo '[INFO] Sleeping...';
         sleep 86400;
       done"

    entrypoint: [ "sh", "-c" ]
    command: >

         echo '[INFO] Sleeping...';
         sleep 86400;
       done"

This looks like a fairly good solution. @AxisNL : what do you think? does this solver your issue?
