问题
关注 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
它一直在“等待...”
我遵循了文档中的所有内容，并不断重试但一直失败，任何帮助将不胜感激？
更新：
usingdocker-compose正在工作，但我仍然很好奇为什么运行 withdocker stack ...不起作用
额外细节
软件版本：
Pop!_OS 20.04 LTS

这是docker logspostgres：

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.
