Docker容器重启失败

Question

你好，我有2个docker容器：一个用于wordpress，另一个用于DB。我想在wordpress容器中复制html和php文件，因为我看到它必须首先停止容器，否则将无法完成复制。除非我在容器中复制了之后：

docker restart $(docker ps -a -q)

我遇到此错误：

Error response from daemon: Cannot restart container 035714167b27: network 87e28d3e4121e59f1a3dab6e0afc81db6f273e2585fe22045f3dcd7edcd3ae5d not found
Error response from daemon: Cannot restart container 2169bed03e64: network 87e28d3e4121e59f1a3dab6e0afc81db6f273e2585fe22045f3dcd7edcd3ae5d not found

即使我一个接一个地重新启动容器，我也会遇到错误：例如：

Error response from daemon: Cannot restart container 035714167b27: network 87e28d3e4121e59f1a3dab6e0afc81db6f273e2585fe22045f3dcd7edcd3ae5d not found

这是我的docker-compose.yml文件：

version: '3.1'

services:

  wordpress:
    image: wordpress
    restart: always
    networks:
      - database
    ports:
      - 8080:80
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_USER: exampleuser
      WORDPRESS_DB_PASSWORD: ******
      WORDPRESS_DB_NAME: exampledb

  db:
    image: mysql:5.7
    restart: always
    networks:
      - database
    environment:
      MYSQL_DATABASE: exampledb
      MYSQL_USER: exampleuser
      MYSQL_PASSWORD: examplepass
      MYSQL_RANDOM_ROOT_PASSWORD: '********'
networks:
  database:

docker-compose up命令出错：

Starting wordpress_db_1        ... error
Starting wordpress_wordpress_1 ...

Starting wordpress_wordpress_1 ... error

ERROR: for wordpress_wordpress_1  Cannot start service wordpress: network 87e28d3e4121e59f1a3dab6e0afc81db6f273e2585fe22045f3dcd7edcd3ae5d not found

ERROR: Encountered errors while bringing up the project.

对于docker-compose down命令：

Removing wordpress_wordpress_1 ... done
Removing wordpress_db_1        ... done
Removing network wordpress_database

docker network ls命令的输出：

NETWORK ID          NAME                  DRIVER              SCOPE

03cc07eda9e8        wordpress_wordpress   nat                 local

信息：

1. Windows 10
2. Docker版本2.0.0.2（30215）

预先感谢您！

您正在使用docker compose进行启动吗？ 如果是这样，则可能在网络的最后一个容器退出时删除了该网络。 我不会手动复制文件，而是使用卷绑定，这样就无需将文件复制到容器中了，这是一个巨大的危险信号
