永远不要将容器设置为' up‘[docker]

Question

我自己做了一个Dockerfile和一个docker-compose.yml，并尝试用docker-compose.yml做容器。apache容器工作正常:稳定，但db容器不能。它永远不会成为状态up。

/work_space
      |-eccube #docker-compose.yml
      |        #Dockerfile
      |
      |-eccube-data #db
                    #data
                    #ececcube-2.4.1
                    #html

使用docker logs <db container ID>查看发生了什么↓

我将向您展示解决此问题所需的代码/文件。

/w/eccube ❯❯❯ docker ps                                                                                                                                                                                ✘ 1

在var/lib/mysql中，这些文件和目录存在。

root@f4680fa4d3f4:/var/lib/mysql# ls
auto.cnf    ca.pem       client-key.pem  ib_logfile0  ibdata1  mysql           private_key.pem  server-cert.pem  sys
ca-key.pem  client-cert.pem  ib_buffer_pool  ib_logfile1  ibtmp1   performance_schema  public_key.pem   server-key.pem

然后，在/work_space/eccube_data/db中，这些我们实际上是同步的！

/w/e/db ❯❯❯ ls
auto.cnf           ca.pem             client-key.pem     ib_logfile0        ibdata1            mysql              private_key.pem    server-cert.pem    sys
ca-key.pem         client-cert.pem    ib_buffer_pool     ib_logfile1        ibtmp1             performance_schema public_key.pem     server-key.pem

Answer 1

使用Docker for Mac时，以下内容将数据存储在嵌入式VM中，因为此目录没有映射到您的Mac环境：

  - /work_space/eccube-data/html:/var/www/html
  - /work_space/eccube-data/data:/var/www/data

和

  - /work_space/eccube-data/db:/var/lib/mysql

相反，您希望使用相对路径：

  - ../eccube-data/html:/var/www/html
  - ../eccube-data/data:/var/www/data

和

  - ../eccube-data/db:/var/lib/mysql

这里假设您从eccube目录内部运行docker-compose命令，并且您的项目位于区分大小写的/Users目录中(请参阅有关在Docker for Mac getting started guide中使用其他目录的更多信息)。

Answer 2

我删除了container、image和volume，然后执行了docker-compose up -d。啊，真灵。现在我有了正确的容器。

非常感谢!
