Dockerfiles in the Docker Demonstration for the Visual COBOL Base Image

This topic describes in detail the commands used by the Dockerfiles in the Docker demonstration for the Visual COBOL base image.

The following Dockerfiles are used:

Dockerfile
The main Dockerfile used to create the image for Visual COBOL. The image created uses OpenJDK from AdoptOpenJDK to provide Java support. Visual COBOL does not include the files that provide this support, so you must obtain these files yourself.
Dockerfile.nojava
Additional Dockerfile to produce a base image for Visual COBOL that does not include Java support. You might want to use this if your system already includes a number of different versions of Java and you don't want to introduce another version unnecessarily.
Dockerfile.oraclejava
Additional Dockerfile to produce a version of the Visual COBOL base image that uses the Oracle JDK to provide Java support. Visual COBOL does not include the files that provide this support, so you must obtain these files yourself and ensure that you are licensed to use them.
Dockerfile.x86
Additional Dockerfile to produce a base image for Visual COBOL for use with 32-bit applications.
Dockerfile.x64
Additional Dockerfile to produce a base image for Visual COBOL for use with 64-bit applications.
