The unhandled exception could crash the deck-chores container

[vitoyucepi]

Summary

I found a case when managing the containers labels related to deck-chores could trigger various exceptions.

This exception causes the deck-chores container to crash.

Traceback (most recent call last):
  File "/usr/local/lib/python3.11/site-packages/docker/api/client.py", line 268, in _raise_for_status
    response.raise_for_status()

The above exception was the direct cause of the following exception:

Reproduction

1. Start deck-chores docker run -it -v /var/run/docker.sock:/var/run/docker.sock -e TZ=UTC funkyfuture/deck-chores:1.3.10.
2. Create two compose configs for the same server.
   compose1.yaml

   services:
     test:
       image: alpine:3.17
       labels:
         deck-chores.test.command: env
         deck-chores.test.interval: every minute
       command: sleep 1000
       stop_grace_period: 1s

   compose2.yaml

   services:
     test:
       image: alpine:3.17
       labels:
         deck-chores.test.command: env
         deck-chores.test.interval: every second
       command: sleep 1000
       stop_grace_period: 1s

3. Run command docker-compose -f compose1.yaml up -d; docker-compose -f compose2.yaml up -d; docker-compose -f compose1.yaml up -d.

Version

• docker: 20.10.23
• docker-compose: 2.16.0
• deck-chores: 1.3.10

Additional

There are also other exceptions, but they don't terminate the container.
