So, lets start with a simple java application,Д¬reate a Dockerfile to install Apache Tomcat 8 and copy our created war file into TomcatвЂ™s webapps folderДЇROM /ubi8/openjdk-11 And after that, iвЂ™ll deploy a simple hello world java application on top of Tomcat 8. On this sample, im trying to create a Apache Tomcat 8 (version 8.0.5 to be precise), and deploy it on top on a UBI8 base image, with JDK 11 installed on it. UBI images can be obtained from the Red Hat container catalog, and be built and deployed anywhere. Like previous base images, they are built from portions of Red Hat Enterprise Linux. To run session replication in your Tomcat 8 container, the following steps should be completed: All your session attributes must implement java.io.Serializable Uncomment the Cluster element in server.xml If you have defined custom cluster valves, make sure you have the ReplicationValve defined as well under the Cluster element in server.

UBI (Universal Base Image) 8 is an OCI-compliant container base operating system images with complementary runtime languages and packages that are freely redistributable.
