Hello, I want to create a dockerfile with wordpress, mysql, ftp and phpmyadmin. I want that the container hosts a web site. Both the customer and the container, I have a container nginx-proxy which is on the port 80. I do not know how to take myself there to create the dockerfile. can you help me? Thank’s
