无法连接到端口8080管理员Postgres + Adminer Docker堆栈

如何解决无法连接到端口8080管理员Postgres + Adminer Docker堆栈

问题

遵循postgres docker官方页面： https://hub.docker.com/_/postgres

我创建了“ stack.yml” 它包含：

# Use postgres/example user/password credentials
version: '3.1'

services:
  db:
    image: postgres
    restart: always
    environment:
      POSTGRES_PASSWORD: example

  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080

然后运行命令：

$ docker stack deploy -c stack.yml postgres

但是完成后，我无法打开http：// localhost：8080

它保持“等待...”

我遵循了文档中的所有内容，并继续重试，但仍然失败，对您的帮助会非常感激吗？

更新：

使用docker-compose可以正常工作，但是我仍然很好奇为什么使用docker stack ...不能正常工作

这里是docker logs for postgres：

Success. You can now start the database server using:

    pg_ctl -D /var/lib/postgresql/data -l logfile start

initdb: warning: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A,or
--auth-local and --auth-host,the next time you run initdb.

这是docker logs位管理员：

解决方法

使用IP地址而不是hostname
