fix(workers tasks): get_workers works with docker ps header

[ternel]

Hi there,

Thanks for this awesome tool folks!

I have an issue with the get_workers function, I think it's from a new docker version, but not sure. /shrug

$ docker --version
Docker version 23.0.6

$ inv start 
Encountered a bad command exit code!

Command: 'docker update --restart=no NAMES     IMAGE     CREATED ago   STATUS    COMMAND'

Exit code: 1

Stdout:



Stderr:

Error response from daemon: No such container: NAMES
Error response from daemon: No such container: IMAGE
Error response from daemon: No such container: CREATED
Error response from daemon: No such container: ago
Error response from daemon: No such container: STATUS
Error response from daemon: No such container: COMMAND

$ docker ps -a --filter "label=docker-starter.worker.lookcycle" --quiet
NAMES     IMAGE     CREATED ago   STATUS    COMMAND

I've updated the function to check if the header is displayed. (Maybe a better way to do this?)

--quiet fixed in docker 24
