Radicale won't start

[frimdo]

Hi, I am facing quite a wierd issue, where the radicale appears not to start up at all. Steps to reproduce:

$ git clone https://github.com/tomsquest/docker-radicale
$ cd docker-radicale/
$ mkdir data
$ docker-compose up
$ docker-compose logs radicale
Attaching to radicale

The Attaching to radicale is the only message that ever appears in logs. Apart from that, webpage is inaccessible although the server seems to work a bit

$ curl -f http://127.0.0.1:5232
Redirected to /.web

Tried older version (3.1.6.0) and the result is the same. I am running on Aynology DSM 6.2.4-25556 Update 4.

Uh... Two days of debugging and now 15min after releasing I finally stumble upon the UID and GID issues. Well, I did not manage to solve this either.

• Synology does not allow me to use option 1, as addgroup command cannot be found.
• Option 2 (forcing IDs using variables) did not change the behavior.
• I also tried option 0, creating a data dir with correct IDs (chown 2999:2999 data), but no change.

Hi @frimdo ,

Having not output except Attaching to radicale is ok. Radicale does not log anything on start by default,

$ curl -f http://127.0.0.1:5232 Redirected to /.web

This means everything is fine, on the host you executed this.

Make sure that the port 5232 is reachable on your network (firewall, router...). I cannot help you more, this largely depends on your setup.

Finally solved the issue by setting

    ports:
      - 5232:5232

instead of

    ports:
      - 127.0.0.1:5232:5232

in docker-compose.yml. Is there any reason for the 127.0.0.1 part?

Security. Only bind to the host.

Usually, you will have a proxy between you and Radicale. This proxy will do https/security... I personnally use Caddy (caddyserver). Traefyk, nginx are alternatives.
