尝试通过浏览器在我的机器上查看 docker 容器运行

Question

我是运行两个容器。一个是Keycloak（用于访问管理/授权/认证），另一个是用于存储Keycloak信息的mariadb数据库。

我的问题是我无法在浏览器中访问 Keycloaks 管理面板，尽管后台有容器运行（通常由运行 localhost:8080/auth 完成）。

有人可以指出我做错了什么的正确方向吗？

我的 Dockerfile:

我在浏览器中尝试了以下地址，但无济于事：

localhost:8080/auth
localhost:8443/auth
localhost:9990/auth

127.0.0.1:8080/auth 
127.0.0.1:8443/auth 
127.0.0.1:9990/auth 

172.19.0.0:8080/auth 
172.19.0.0:8443/auth 
172.19.0.0:9990/auth 

172.19.0.1:8080/auth
172.19.0.1:8443/auth
172.19.0.1:9990/auth

172.19.0.3:8080/auth
172.19.0.3:8443/auth
172.19.0.3:9990/auth

您还没有发布任何端口。

更新 docker-compose 文件中的 keycloak 服务。

keycloak:
    image: quay.io/keycloak/keycloak:latest
    ports:
      - 8080:8080        ### THIS IS MISSING
    environment:
      DB_VENDOR: mariadb
      .
