Dockerfile Image命令'/ bin / sh

Your problem is with the line rm -rf /var/lib/apt/lists/*. You are deleting the lists that have been fetched by the apt-get update. You then try to install a package using apt. This will fail.

You need to move rm -rf /var/lib/apt/lists/ after the line that installs mysql-server.
