Oracle WebLogic 14.1.1 under Podman

Posted by Dirk Nachbar on Monday, May 18, 2020 with No comments
Since a few weeks the latest release of the Oracle WebLogic Server 14.1.1.0.0 is available and I was testing it already on native Linux Servers and within Docker.
Now it's time to check Oracle WebLogic Server 14.1.1.0.0 under Podman https://podman.io 

At first you will need an Oracle Linux 8.2 Server with podman. A really good instruction you can find at oracle-base.com https://oracle-base.com/articles/linux/podman-install-on-oracle-linux-ol8

As a starting point, just clone my GitHub Repository https://github.com/DirkNachbar/Docker there you will find some Dockerfiles for Oracle WebLogic Server 14.1.1.0.0

The first task is to create a JDK 11 Podman Image.

Under my GitHub Repository in the subdirectory OracleWebLogic/dockerfiles/14.1.1.0.0/serverjre/java-11 you will find a Dockerfile for a JDK 11 Image.
Simply download from Oracle Technology Network https://www.oracle.com/java/technologies/javase-jdk11-downloads.html the Linux Compressed Archive of the JDK 11 and place it in the directory OracleWebLogic/dockerfiles/14.1.1.0.0/serverjre/java-11
Then just run the podman build command as follows:

[root@podman java-11]# 
[root@podman java-11]# cat Dockerfile
#
# Dockerfile for creating Oracle JDK 11 Images based on OL latest
#
FROM oraclelinux:7-slim

Now as next we can build the Oracle WebLogic Image. For this download the Oracle WebLogic 14c Generic Installer from https://www.oracle.com/middleware/technologies/fusionmiddleware-downloads.html and place the installer (dont unzip it) into the subirectory OracleWebLogic/dockerfiles/14.1.1.0.0
After you have placed the Generic Installer, you can execute the podman build to build the Oracle WebLogic Image as follows

[root@podman 14.1.1.0.0]#
[root@podman 14.1.1.0.0] podman build -t oracle/weblogic:14.1.1.0.0-optimized -f Dockerfile.optimized

The final step is to create a pod and a running container with Oracle WebLogic Server 14.1.1.0.0.
The pod creation and the container creation can be done within one single command:

[root@podman 14.1.1.0.0]#
[root@podman 14.1.1.0.0] podman run -d --name [Name of your Container] --pod=new:[Pod Name] \
             -p 7001:7001 -p 9002:9002 \
             -v [Directory to your domain.properties file]:/u01/oracle/properties \
             -e ADMINISTRATION_PORT_ENABLED=true -e DOMAIN_NAME=[WebLogic Domain Name] \
             oracle/weblogic:14.1.1.0.0-optimized
# E.g.:
[root@podman 14.1.1.0.0] podman run -d --name wls1411optimized --pod=new:pod_wls1411 \
             -p 7001:7001 -p 9002:9002 \
             -v /work/Docker/OracleWebLogic/dockerfiles/14.1.1.0.0/properties:/u01/oracle/properties \
             -e ADMINISTRATION_PORT_ENABLED=true -e DOMAIN_NAME=OptimizedDomain \
             oracle/weblogic:14.1.1.0.0-optimized

# Let's check the pod creation:
[root@podman 14.1.1.0.0] podman pod ls
POD ID         NAME          STATUS    CREATED          # OF CONTAINERS   INFRA ID
4e0b599d0083   pod_wls1411   Running   12 seconds ago   2                 68ccf98d911a

# Let's check the WebLogic Container:
[root@podman 14.1.1.0.0] podman ps
CONTAINER ID  IMAGE                                           COMMAND               CREATED         STATUS             PORTS                   NAMES

As you can see, it's really easy to get Oracle WebLogic Server 14c up and running under Podman.
