mysql - 切勿将容器设置为 'up' [docker]

Question

我做了一个Dockerfile和一个 docker-compose.yml我自己并尝试从 docker-compose.yml 制作容器。apache容器工作正常:稳定但 db容器没有。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

二手docker logs <db container ID>看看发生了什么↓

我将向您展示解决此问题所需的代码/文件。

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，确实，那些我们是同步的!!!

/w/e/db ❯❯❯ ls

Answer 1

使用 Docker for Mac，以下内容将数据存储在嵌入式 VM 内，因为该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，您想使用相对路径:

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

和

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

这假设您从 eccube 目录中运行 docker-compose 命令，并且您的项目位于 /Users 目录中，该目录区分大小写(查看更多关于使用 Docker for Mac getting started guide 中的其他目录)。
