To successfully create a Docker image using a Dockerfile, you must know some basic commands. If you want to copy multiple directories (not their contents) under a destination directory in a single command, you'll need to set up the build context so that your source directories are under a common parent and then COPY that parent. You need to name some directory that contains all the files that you need to copy in in the docker build command (maybe docker build ~/go ); the Dockerfile needs to be in that directory (or directory tree, with a -f option) and it can only use relative paths. This is about the simplest sort of dockerfile you can create: FROM microsoft/iis:nanoserver COPY site C:/inetpub/wwwroot All this dockerfile is saying is that our base image is the Microsoft IIS nanoserver image from DockerHub, and then we want to copy the contents of our local site directory into C:/inetpub/wwwroot.
