To run PAS for OpenEdge in a Docker container, JDK is required in /usr/java, inside the PAS for OpenEdge container.

Note: The Platform Compatibility Guide (PCG) provides a list of all the supported JDK versions that can be used for the JDK image.

How to obtain the JDK Docker image

You can obtain the JDK Docker image in one of the following ways:
  • Download a JDK Docker image from AdoptOpenJDK, Docker Hub, or any other site certified by Progress and listed in the Platform Compatibility Guide. You must use a Linux 64 image. The JDK version required is jdk-8u221-linux-x64.tar.gz or later.
  • Build a custom Docker image with a downloaded JDK:
    Note: If you use an AdoptOpenJDK Docker image, then you can skip these steps.
    1. Download the compressed version of JDK 8 for Linux x64. The filename may be in following pattern: jdk-8u*-linux-x64.tar.gz
    2. Create a Dockerfile in the same folder as the downloaded archive file with following code, and build the image. Then, give the image a suitable name. You can edit the code to reflect the file name to match the downloaded .tar file: 
      FROM alpine:3.8
								
								ENV JAVA_PKG=jdk-8u*-linux-x64.tar.gz
								
								ADD $JAVA_PKG /usr/java/
								
								RUN export JAVA_DIR=$(ls -1 -d /usr/java/*) && \
								ln -s $JAVA_DIR /usr/java/latest && \
								ln -s $JAVA_DIR /usr/java/default
    3. To build an image from the Dockerfile, run the following command in the same folder: 
      $ docker build -t imageName:tag

      Note the values for imageName:tag because you will use them in a later step.
