Dockerfiles in the Docker Demonstration for the Enterprise Developer Base Image (for Enterprise Developer UNIX Components)

Note: This topic only applies if you are using Enterprise Developer UNIX Components.

This topic describes in detail the commands used by the Dockerfile in the Docker demonstration for the Enterprise Developer base image. The Dockerfile is listed in its entirety and a following table describes the various Dockerfile commands. The line numbers in the listings of the Dockerfile have been added to aid readability. They are not present in the supplied Dockerfile.

Note: The Dockerfiles supplied for Red Hat Linux and SUSE Linux differ slightly. The Dockerfile shown below is the one supplied with Red Hat Linux. Where there are differences between the two versions they are described in the following table.

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

Lines Description
003 Specifies the base image to use. For Red Hat this is the official Docker image for Red Hat Enterprise Linux.

For SUSE Linux this line is as follows:

FROM suse/sles12sp3

This specifies that the base image to use is the official Docker image for SUSE Linux Enterprise Server.

010 - 018 Define build arguments passed by the docker build command:
  • PRODUCT_VERSION.Indicates the version of Enterprise Developer that this Dockerfile is supplied with.
  • SETUP.EXE. Specifies the name of the Enterprise Developer installation file. The default setting is the name of the file supplied with Enterprise Developer.
  • ACCEPTEULA. Indicates whether the terms of the Micro Focus End User License Agreement (EULA) have been accepted.
  • LOGFILE. Specifies the name to use for the log file created when installing Enterprise Developer into the image.
  • MFLICFILE. Specifies the name of the license file to use for Enterprise Developer.
  • ESADM_UID. Specifies the user ID to use for the Enterprise Server admin user.
  • ESADM_GID. Specifies the group ID to use for the Enterprise Server admin user.
  • ESADM_USER. Specifies the ID to be used for the Enterprise Server admin user.
  • ESADM_SHELL. Specifies the shell to use for the Enterprise Server admin user.
020 - 024 Specify the metadata labels for the image that will be created. These labels can be queried using the docker inspect command.
026 - 027 Create environment variables to be used in this Dockerfile:
  • MFPRODBASE. Specifies the folder into which Enterprise Developer is installed.
  • MFLICBASE. Specifies the folder where the Micro Focus License Administration tool is installed.
032 Install software that is required to be able to install Enterprise Developer.
035 Copy the installation file for Enterprise Developer into a temporary folder.
038 - 039 Run a series of concatenated commands to add the Enterprise Server admin user and set up the shell to be used by that user.
042 - 046 Run a series of concatenated commands to perform the following actions:
  1. Make the Enterprise Developer installation file executable.
  2. Run the Enterprise Developer installation file using options to indicate acceptance of the license agreement and to specify the System Administrator Process User ID.
  3. Delete the temporary folder that you created earlier (containing the Enterprise Developer installation file).
  4. Configure the dynamic linker run-time bindings to include the shared objects supplied with Enterprise Developer.

    Doing this avoids the need to update the LD_LIBRARY_PATH environment variable.

049 - 050 Copy the license file to a temporary location, use it to license Enterprise Developer, then delete the license file.
053 Copy the default environment that is to be used when someone logs on as root.
057 Run a script to reset the temporary file used when applying the license for Enterprise Developer.
