IBM WebSphere Liberty
WebSphere Liberty is the only application server supported by Cúram on Kubernetes and is therefore required.
When installed, create an environment variable WLP_HOME that points to the WebSphere Liberty installation directory. For example:
WLP_HOME=/opt/IBM/WebSphere/Liberty
Java Requirement
As of the Cúram 8.2 release, Cúram supports Java 8 and Java 21 , the latest version of Java will be referred to as ModernJava.
See Cúram Supported Prerequisites for the latest list of supported Java versions and JDK distributions.
After installing Java, set the JAVA_HOME environment variable as follows:
export JAVA_HOME=$WLP_HOME/java/<version>
- Add
$JAVA_HOME/binto thePATHenvironment variable.
Because of compatibility differences between Java 8 and Java 21, the Dockerfiles used by Cúram have been separated into version-specific directories. Java8 and ModernJava. These directories are referenced using the placeholder $CURAM_JAVA_MODE in this documentation.
Be sure to check the dockerfiles/Liberty directory to confirm that you’re using a supported Java version.
Database
A supported relational database is required. See Cúram Supported Prerequisites for list of supported databases.

When using Java 8, Apache Ant 1.10.6 is required.
When using ModernJava, Apache Ant 1.10.15 is required.
