issue with latest docker build

Hi
I'm new to containers
I'm running this on proxmox lxc  -> debian -> podman
I'm using this docker-compose.yml

version: '3.8'

services:
  guacd:
    image: guacamole/guacd:latest
    restart: always
    network_mode: bridge

  postgres:
    image: postgres:latest
    restart: always
    network_mode: bridge
    environment:
      POSTGRES_DB: guacamole_db
      POSTGRES_USER: guacamole_user
      POSTGRES_PASSWORD: X
    volumes:
      - /root/guacamole/pdata:/var/lib/postgresql/data

  guacamole:
    image: guacamole/guacamole:latest
    restart: always
    network_mode: bridge
    ports:
      - "8080:8080" # Or change to a different host port if 8080 is in use
    environment:
      GUACD_HOSTNAME: guacd
      POSTGRESQL_HOSTNAME: postgres

when i started this about 3 days go it worked

did a pull -d and it was working I could connect . i deleted and recreated
a few times.

But recently I tried again and its failing .

I'm thinking it can't connect and this is a podman issue - but I also
notice there as a new image pushed to docker.io - i did try the previous
version same issue ...

This might just be me and not know what to do with podman , but it was
orignally working ...

thanks

Hi

converted to quadlets - my first attempt failed - same error - i have to
change the hostname to include the pod name ...
i checked the container /etc/hosts file
so it seems to be working now.

so I think this was a me not knowing containers issue

thanks

This really looks like something has stopped working in your Postgres DB
container, so might be worth verifying that. Otherwise, if you can set the
environment variable LOG_LEVEL to "debug" for the guacamole container and
give it another go, maybe it'll yield some more useful information.

The push of the later image to the Docker Hub is probably just dependency
updates for the underlying Linux container - we haven't changed the
released version of Guacamole since the 1.6.0 release, so nothing that
you're seeing has changed in the Guacamole code.

Re: issue with latest docker build

Posted by Antoine Besnier <be...@yahoo.fr.INVALID>.
 I know you fixed it already, but the cause was most likely the release of Postgresql 18, on the 25th of september.So if you pulled the images again, your postgres image updated from 17 to 18, and major releases are not 1-to-1 compatible. You need to backup your db with 17 image, stop, start the 18 image, and restore the db.

I'm thinking it can't connect and this is a podman issue - but I also notice there as a new image pushed to docker.io - i did try the previous version same issue ... 

This might just be me and not know what to do with podman , but it was orignally working ...
thanks
