Add list ports command(s)

[saltydk]

Add one or several commands related to identifying what hostname and port to use for a given role/install.

Some boilerplate Python:

import docker

client = docker.from_env()

def get_traefik_service_info(container):
    labels = container.labels
    services_info = []

    # Filter Traefik service labels
    for key, value in labels.items():
        if 'traefik.http.services' in key and '.loadbalancer.server.port' in key and '-http' not in key:
            # Adjusted to correctly parse the service name
            service_name = key.split('.')[3]
            services_info.append((service_name, value))

    return services_info

def get_port_bindings(container):
    port_bindings = container.attrs['HostConfig']['PortBindings'] or {}
    binding_info = ', '.join([f"{k} -> {', '.join(vv['HostPort'] for vv in v)}" for k, v in port_bindings.items()]) if port_bindings else "No port bindings"
    return binding_info

def print_service_info(container):
    services_info = get_traefik_service_info(container)
    binding_info = get_port_bindings(container)

    # Print only if there are Traefik services or port bindings
    if services_info or binding_info != "No port bindings":
        print(f"Container:       {container.name}")
        if services_info:
            for service_name, port in services_info:
                print(f"Traefik Service: {service_name} - Port: {port}")
        else:
            print("Traefik Service: None")
        print(f"Port Bindings:   {binding_info}\n")

def main():
    for container in client.containers.list():
        print_service_info(container)

if __name__ == "__main__":
    main()

Not the best format as far as the output so could use some formatting suggestions as to what we want this to output both as a single container lookup and as a look at everything installed output.

How about a table? Something like:

Something like that?

I like yours salty. I came up w this :p kinda ugly. I feel like i should leave this up to the adults. I can drop the "no port bindings" and the -> port but yours is pertier.

Yes, even better with row dividers. Could also cut down the headers a bit so they stand out more (or less?):

I like them sorted :p

[keldian]

Sorting is a given. The question is by which attribute first, container? port?

There will be a single container lookup argument anyway, so we won't need sorting to find a specific thing, at least.

[RaneyDazed]

isn't the idea to have either a single container lookup or lookup all? in which case alphabetical sort might be nice. like sb ports or sb ports sabnzbd?

I tried with and without alphabetical sort by container name and I think readability is cleaner with alphabetical. I don't think there's much use for sorting by port, but I could be wrong.

[keldian]

"Cleaner" I don't see how, and again, I can't think of a practical use for sorting the full list by `container` besides finding a specific row more easily—a use case the single container lookup already covers—but let me know if there is one.

On the other hand, it might be interesting to have a quick notion of which containers use the same listening port, for that limited use case where a user might want to publish them and avoid conflicts at least. Idk.
