FROM iIt sets the Base Image for subsequent instructions. MAINTAINER It sets the Author field of the generated images. RUN It will execute any commands when Docker image will be created. CMD It will execute any commands when Docker container will be executed. ENTRYPOINT It will execute any commands when Docker container will be executed. LABEL It adds metadata to an image. EXPOSE It informs Docker that the container will listen on the specified network ports at runtime. ENV It sets the environment variable. ADD It copies new files, directories or remote file URLs. COPY It copies new files or directories. The differences of [ADD] are that it's impossible to specify remore URL and also it will not extract archive files automatically. VOLUME It creates a mount point with the specified name and marks it as holding externally mounted volumes from native host or other containers USER It sets the user name or UID. WORKDIR It sets the working directory.
