如何重新启动停止的 docker 容器？

Question

我提取了一个postgres映像并创建了一个名为pgdb的 docker 容器，该容器已退出。 这是输入docker ps -all后终端返回的内容：

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                      PORTS               NAMES
e62fdb45c727        postgres            "docker-entrypoint.s…"   19 hours ago        Exited (1) 14 minutes ago                       pgdb

now I am trying to restart my container by typing docker exec -it pgdb bash , however I am getting the following error message: Error response from daemon: Container e62fdb45c727baf9ca9d7b55401f870b35959a10f356a401f058f2e693adc2fd is not running

我试图像这样附加容器：

random@random-142:~$ sudo docker start pgdb
pgdb
random@random-142:~$ sudo docker attach pgdb
You cannot attach to a stopped container, start it first

但它也没有用。 有谁知道我如何解决这个问题？ 我真的很绝望。

容器日志

random@random-142:~$ sudo docker logs pgdb
Error: Database is uninitialized and superuser password is not specified.
       You must specify POSTGRES_PASSWORD to a non-empty value for the
       superuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".

       You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all
       connections without a password. This is *not* recommended.

       See PostgreSQL documentation about "trust":
       https://www.postgresql.org/docs/current/auth-trust.html

Answer 1

docker 容器日志本身是不言自明的。 您需要指定数据库和超级用户密码。

在运行 Postgres docker 容器时添加以下 arguments：

-e "POSTGRES_DB=YOUR_DB_NAME" -e "POSTGRES_PASSWORD=YOUR_PASSWORD"

例子：

docker run -itd -p 5432:5432 -e "POSTGRES_DB=testdb" -e "POSTGRES_PASSWORD=password" --name pgdb postgres

如果您不愿意添加任何密码，请使用"POSTGRES_HOST_AUTH_METHOD=trust" 。 例子：

docker run -itd -p 5432:5432 -e "POSTGRES_DB=testdb" -e "POSTGRES_HOST_AUTH_METHOD=trust" --name pgdb postgres

Answer 2

要重新启动容器，您可以使用此命令

docker start -ai "container_name"
