docker - Keycloak 8 : User with username 'admin' already added

Question

我无法使用ansible和docker-compose启动keycloak容器。我收到错误消息:用户名“admin”的用户已添加到“/opt/jboss/keycloak/standalone/configuration/keycloak-add-user.json”

我有3个忙碌的工作:

创建网络:

- name: Create a internal network
  docker_network:
    name: internal

设置postgres:

- name: "Install Postgres"
  docker_compose:
    project_name: posgressdb
    restarted: true
    pull: yes
    definition:
      version: '2'
      services:
        postgres:
          image: postgres:12.1
          container_name: postgres
          restart: always
          env_file:
            - /etc/app/db.env
          networks:
            - internal
          volumes:
            - postgres-data:/var/lib/postgresql/data
            - /etc/app/createdb.sh:/docker-entrypoint-initdb.d/init-app-db.sh
          ports:
            - "5432:5432"
      volumes:
        postgres-data:
      networks:
        internal:
          external:
            name: internal

创建 key 斗篷容器:

- name: Install keycloak
  docker_compose:
    project_name: appauth
    restarted: true
    pull: yes
    definition:
      version: '2'
      services:
        keycloak:
          image: jboss/keycloak:8.0.1
          container_name: keycloak
          restart: always
          environment:
            - DB_VENDOR=POSTGRES
            - DB_ADDR=postgres
            - DB_PORT=5432
            - DB_SCHEMA=public
            - DB_DATABASE=keycloak
            - DB_USER=keycloak
            - DB_PASSWORD=keycloak
            - KEYCLOAK_USER=admin
            - KEYCLOAK_PASSWORD=admin
          networks:
            - internal
      networks:
        internal:
          external:
            name: internal

有谁知道为什么我会收到此错误？

编辑

如果我将 key 斗篷降级到版本7，它将正常启动!

只是为了阐明其他答案。我遇到过同样的问题。对我有帮助的是:

停止所有容器

注释掉两个相关的行

version: "3"

services:
  keycloak:
    image: quay.io/keycloak/keycloak:latest
    environment:
      # KEYCLOAK_USER: admin
      # KEYCLOAK_PASSWORD: pass
      ...

启动所有容器；

等待，直到keycloak容器已成功启动

停止所有容器，再次

从上面的两行中评论回去

version: "3"

services:
  keycloak:
    image: quay.io/keycloak/keycloak:latest
    environment:
      KEYCLOAK_USER: admin
      KEYCLOAK_PASSWORD: pass
      ...

启动所有容器

这次(及以后的几次)它起作用了。 Keycloak正在运行，并且管理员用户已注册并按预期工作。
