Start Keycloak in docker with standalone-ha mode

Getting advice
1

Hello!

I want to run on AWS two Keycloak instances in docker, in standalone-ha mode, connected to the same RDS Postgres database.
Did I do the docker-compose file correctly?

version: '3'

services:
  keycloak:
    image: quay.io/keycloak/keycloak:12.0.2
    container_name: keycloak
    restart: always
    environment:
      DB_VENDOR: POSTGRES
      DB_ADDR: <DB_HOST>
      DB_DATABASE: <DB_NAME>
      DB_USER: <DB_USER>
      DB_SCHEMA: public
      DB_PASSWORD: <DB_PASSWORD>
      KEYCLOAK_USER: <KC_ADMIN_USER>
      KEYCLOAK_PASSWORD: <KC_ADMIN_PASSWORD>
      PROXY_ADDRESS_FORWARDING: "true"
    command:
      - "--server-config=standalone-ha.xml"
    ports:
      - 8080:8080

Is this code enough:

    command:
      - "--server-config=standalone-ha.xml"

Thanks!

The Keycloak Docker image uses per default the ha option, there’s no need to specify it.
