RUN mkdir c:\myapp. ENTRYPOINT: As mentioned previously, this command will be used to run our JAR file. The following example demonstrates how to build an image named mymod/httpd with the tag v2 based on the oraclelinux:6 image so that it can run an Apache HTTP server. Docker will start containers with, for example, 172.17.0.x. If we have defined WORKDIR directive and want to copy the files or folders to that directory we can simply use the . to copy it to the working directory that is defined by the WORKDIR directive earlier in the Dockerfile.
