Cannot change listening hosts through config file in docker container due to forced host command

[zguig52]

When defining a custom ip / port inside radicale configuration file like this:
hosts = localhost:15232

This parameter is not taken in account due to the CMD arg overloading this inside Dockerfile:
CMD ["--hosts", "0.0.0.0:5232,[::]:5232"]

I think that this line could be removed to avoid these issues, don't you think?

Thank you for creating the issue and PR. I will check it soon.

Thank you for the suggestion. It is good.

Could you share your config file and compose.yaml/docker-compose.yml/docker run command? I was not able to get hosts = localhost:15232to work. Changing it to hosts = 0.0.0.0:15232 works.

I would avoid using hostname localhost, because this can dependent whether /etc/hosts is packaged and what the content is of result in IPv6-only, IPv4+IPv6 or IPv4-only listening (or at least it's try...)

Hi @zguig52 ,

Thank you for taking time to create this issue and PR #1962

Could you have a look at #1960 (comment) and share the details

@kalsi-avneet , sorry for so late replying, I had a quite busy previous week...

I am using Podman, so here is my config file:

.config/containers/systemd/radicale.container

[Unit]
Description=Radicale CalDAV/CarDAV server

[Service]
Restart=always
RestartSec=10
TimeoutStopSec=180

[Container]
Label=app=radicale
ContainerName=radicale
Image=ghcr.io/kozea/radicale:3.5.10
Pod=cloud.pod
ReadOnly=true
Timezone=local
Volume=/shared/data/radicale:/var/lib/radicale:z
Volume=/data/cloud/config/radicale.ini:/etc/radicale/config:ro
Volume=/data/cloud/config/ca.crt:/etc/ssl/ca.crt:ro
Volume=/data/cloud/config/radicale.crt:/etc/ssl/radicale.crt:ro
Volume=/data/cloud/config/radicale.key:/etc/ssl/radicale.key:ro
Exec=--hosts 0.0.0.0:15232

I still need to put the HealthCheck command but cannot yet as I have put SSL.

I also had the bad surprise that binding Radicale to localhost (or 127.0.0.1) is not working neither. I don't know why this is happening, so I had also to bind it to everything. I don't know if this is due to the container or to the python listening bind itself.

I will also review the PR to remove the listening change as it might create major regressions for many people. Maybe using as default conf inside the code a bind of 0.0.0.0 if not specified might support removing this constraint?

@zguig52 ,

Sorry I overlooked this comment.

Thank you for sharing the config file. I am not thoroughly familiar with podman, so let me look at some documentation and get back to you.
