现在就用这个​​拉扯我逐渐下降的发际线几个小时。

编辑：我的映像的Dockerfile：

（除更改密码外）在执行时有效

#docker-compose up --build

我得到一些图像：

# docker images

phpmyadmin/phpmyadmin   latest              9d4ec4bbd5e5        12 days ago         469MB

我将图片标记为我的回购名称。

docker tag noahbuild_www osomanden/debian-noah

因此，我将osomanden / debian-noah上传到我的私有hub.docker.com存储库中

docker push osomanden/debian-noah

一切都很好。没有错误，我是一个快乐的露营者。.图像完成，工作并被推送回购。

删除容器和图像以获得空的工作环境。

docker rm -f $(docker ps -a -q)

和图片

docker rmi $(docker images -q)

空的环境下，我现在拉出先前的图像：

docker pull osomanden/debian-noah

并运行它：

# docker run osomanden/debian-noah

并得到以下结果：

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message

数据库，phpmyadmin等在哪里？

进行检查：

docker inspect osomanden/debian-noah

甚至我对端口443的暴露也消失了。

知道我在做什么错吗？

哦，顺便说一句：

我相信您会混淆3种不同的事物。

图像：用于创建容器的定义。由文件系统层和默认配置组成。这是由Dockerfile定义的。

容器：从图像创建的实例，程序员倾向于将其视为对象与类。该实例可能有许多配置选项被覆盖。

Docker Compose：用于解析具有所有配置选项的yml文件，以运行容器的集合。它还具有使用传递的Dockerfile启动映像构建的功能。

使用docker run时，您将创建一个不使用任何撰写文件设置的容器。而且，如果您检查图像，您将只会看到Dockerfile构建的结果。如果要收集具有根据yml文件配置的网络和卷的容器的集合，则需要运行docker-compose命令，例如：

docker-compose up -d

注意，我还建议在撰写文件中包含您的私人注册表的映像名称。然后，您可以运行docker-compose push和其他节点，因此无需再次运行构建。
