【问题描述】：
我正在尝试在 OSX 10.12.1 上使用 docker 启动并运行 wordpress...
首先我启动mysql：
docker run --name dockermysql -e MYSQL_ROOT_PASSWORD=secret -e MYSQL_DATABASE=wordpress -e MYSQL_USER=wordpress -e MYSQL_PASSWORD=secret -d mysql:5
这似乎工作正常：
$ docker ps -a
f7d1562def4a mysql:5 "docker-entrypoint.sh" 33 minutes ago Up 33 minutes 3306/tcp dockermysql
但后来我尝试了 wordpress……
docker run --name dockerpress --link dockermysql:mysql -d wordpress --net="host" -e WORDPRESS_DB_USER=wordpress -e WORDPRESS_DB_PASSWORD=secret
好像马上就退出了
$ docker ps -a
84cc4d2abb57 wordpress "docker-entrypoint.sh" 7 minutes ago Exited (2) 7 minutes ago dockerpress
f7d1562def4a mysql:5 "docker-entrypoint.sh" 33 minutes ago Up 33 minutes 3306/tcp dockermysql
这是docker inspect dockerpress的结果：

在我看来，在
docker run中，您需要在图像名称之前拥有所有选项。你是为 mysql 做的，但不是为 wordpress 做的。你可以试试docker run --name dockerpress --link dockermysql:mysql --net="host" -e WORDPRESS_DB_USER=wordpress -e WORDPRESS_DB_PASSWORD=secret -d wordpress -
@user2915097谢谢。不过，这似乎并没有太大的区别。 Wordpress 启动得很好，但几乎立即退出，当我检查时有很多空白值（例如没有网络信息）
-
你能启动它并在末尾添加
;docker logs $(docker ps -lq)这应该会显示一些东西 -
@user2915097ah！看起来问题出在 mysql 容器的权限上，因为我没有使用相同的凭据。谢谢 :) 在它完成运行之后，我曾尝试使用
docker logs dockerpress检查日志，但我收到了一个错误，所以这是一个不错的技巧。
