Docker image - argument error - :erlang.binary_to_integer

[pini-gh]

Hi,

Still trying to setup a working docker-compose configuration. Here is my snippet for tmate-master:

  tmate-master:
    image: tmate/tmate-master:latest
    container_name: tmate-master
    restart: unless-stopped
    expose:
    - 4000
    environment:
      MASTER_BASE_URL: https://master-tmate.example.com/
      SECRET_KEY_BASE: secretkeybase
      INTERNAL_API_AUTH_TOKEN: internalapitoken
      PG_URI: postgres://tmate:postgrespassword@tmate-db:5432/tmate
      PG_POOLSIZE: 1
      ERL_COOKIE: erlcookie
      ERL_NODE_NAME: master-tmate.example.com
    networks:
      bridge:
      internal:

  tmate-db:
    image: postgres:12-alpine
    container_name: tmate-db
    restart: unless-stopped
    environment:
      POSTGRES_USER: tmate
      POSTGRES_PASSWORD: postgrespassword
      POSTGRES_DB: tmate
    volumes:
    - pgdata:/var/lib/postgresql/data
    networks:
      internal:

Environment variables guessed from [1] and [2].
|1] https://github.com/tmate-io/tmate-kube/blob/master/prod/master.yaml
[2] https://github.com/tmate-io/tmate-master/blob/master/config/prod.exs

As I understand it, PG_SSL_CA_CERT and MAILGUN_* variables are not mandatory.

With these settings, tmate-master fails at startup with:

What could be missing?

Thanks in advance.

Thanks to gitmemory.com (which is issue #1 actually) I found out that I had to set the container's hostname to something like master-1. Else the hostname defaults to the container id (5b33eff2b1cf in the above error).

  tmate-master:
    image: tmate/tmate-master:latest
    container_name: tmate-master
    hostname: master-1
    restart: unless-stopped
...

Leaving this issue open as it may help others.
