By using the MAINTAINER instruction, you set the Author field of the generated image. This can be your name, username, or whatever you would like as an author of the image that will be created by using the Dockerfile you are writing. This command can be placed anywhere in a Dockerfile, but good practice is to place it on the top of the file, just after the FROM instruction. This is a so-called, non-executing command, meaning that it will not make any changes to the generated image. The syntax, again, is very simple:
MAINTAINER authors_name
