The commands on the lines in this Dockerfile are as follows:

Lines	Description
003	Specifies that the base image to use is the official Docker image for .NET Framework on Windows Server 2016 Server Core.
010 - 015	Define build arguments passed by the docker build command: PRODUCT_VERSION. Indicates the version of Enterprise Server that this Dockerfile is supplied with. ACCEPT_CONTAINER_EULA. Indicates acceptance of the terms laid out in the license agreement. The default setting of "no" means that you must modify this in order to indicate that you accept the terms of the license agreement. ENTSRV_EXE. Specifies the name of the Enterprise Server installation file. The default setting is the name of the file supplied with Enterprise Server. ENTSRV_LOC. Specifies the folder into which Enterprise Server will be installed. TMP_INST_DIR. Specifies a temporary directory to be used while building the image. It is deleted when it is no longer needed. MFLICFILE. Specifies the name of the license file to use for Enterprise Server.
017 - 021	Specify the metadata labels for the image that will be created. These labels can be queried using the docker inspect command.
024 - 025	Create environment variables to be used in this Dockerfile: RMT_DIR specifies the location of the COBOL licensing management software. This is installed when you install Enterprise Server. ENTSRV_LOC is copied from the build argument of the same name that was defined earlier.
027 - 028	Sets the Docker working directory to be the temporary directory then copies the Enterprise Server installation file into it.
029 - 034	Run a series of concatenated Windows commands to: Set some environment variables based on the settings of build arguments. Run the Enterprise Server installation file specifying parameters to install it silently, into the required directory, creating a log file, and indicating that you have accepted the terms laid out in the license agreement.
037	Runs a series of concatenated Windows commands to search the Enterprise Server installation log file for text indicating that the installation failed. If any such text is found no further processing takes place.
040 - 046	Run a series of concatenated Windows commands to license Enterprise Server.
049 - 051	Runs a series of concatenated Windows commands to delete the Enterprise Server installation file and the temporary directory that was used to contain it.
053	Sets the Docker working directory to be the directory into which Enterprise Server was installed.
