Server fails to start with default configuration (znet: ERROR: couldn’t parse IP)

[FatalMerlin]

Describe the bug
Server fails to start with default configuration (znet: ERROR: couldn’t parse IP).

The default LGSM configuration provides the IP as "0.0.0.0", which the server does not parse / allow.
The server must be configured to use the docker IP address.

To Reproduce

1. Create a new server as described in the README
2. Wait for the server to fail during startup

Expected behavior
The image should read the container IP address and set the server IP accordingly.

Additional context
Reference: Linux GSM Forum

Workaround
The problem can be fixed using Docker Compose and changing the compose file to give the container a static IP address and add it to the LGSM instance config:

version: "3.0"

services:
    project-zomboid:
        image: cyrale/project-zomboid
        restart: unless-stopped
        environment:
            SERVER_NAME: "MyServer"
            SERVER_PASSWORD: "Sh00tZ0mb13s"
            ADMIN_PASSWORD: "l3tm31n"
            PLAYER_PORTS: "10"
            # SERVER_BRANCH: "iwillbackupmysave"
            # Insert server IP into LGSM instance config
            LGSM_SERVER_CONFIG: |
              ip="172.20.128.2"
        ports:
            - "8766:8766/udp"
            - "8767:8767/udp"
            - "16261:16261/udp"
            - "16262-16272:16262-16272"
            - "27015:27015"
        volumes:
            - ./server-data:/server-data
            - ./server-files:/server-files
        # Give the container a static IP address
        networks:
            static-network:
              ipv4_address: 172.20.128.2
        restart: always

# Create a network to apply a conflict free static IP
networks:
  static-network:
    ipam:
      config:
        - subnet: 172.20.0.0/16

There is a little error in the configuration. PLAYER_PORTS: "10" should be PLAYER_PORTS: "16262-16272". I update README with a better explanation for this variable, see it here.

I also notice that you have 2 restart directive in your docker-compose.yml.

If that's not the problem, would you have the details of the error message? The server seems to start well on my side.

Sorry, I just saw the error message. I will check this later.

I made a fix to auto-assign the container IP to the game server. It's available in 0.2.1.

I also notice that you have 2 restart directive in your docker-compose.yml.

Twice the charm!

Thanks for the fix and pointing out the config adjustments.
Should I test or should we close this?

[cyrale]

Test it and close this issue if it's good for you 😉

[markjaniczak]

I've updated my image to the latest and also get this error but haven't supplied an IP address in my config like above

[cyrale]

Could you give me more details about your configuration? which OS? what commands used to start the server?
