Apache Tomcat, often referred to as Tomcat, is an open-source web server and servlet container developed by the Apache Software Foundation. Tomcat implements several Java EE specifications including Java Servlet, JavaServer Pages, Java EL, and WebSocket, and provides a "pure Java" HTTP web server environment for Java code to run in.

Based on the Bitnami Tomcat image for docker, this Chart bootstraps a Tomcat deployment on a Kubernetes cluster using Helm Classic.

Persistence

For persistence of the Tomcat data, mount a storage volume at the /app path of the Tomcat pod.

By default the Tomcat Chart mounts an emptyDir volume.

Configuration

To edit the default Tomcat configuration, run

$ helmc edit tomcat

Configurable parameters can be specified in tpl/values.toml. If not specified default values as defined by the Bitnami Tomcat image are used.

Tip: If you have issues running the above command, add se autochdir to your ~/.vimrc profile or simply edit ~/.helmc/workspace/charts/tomcat/tpl/values.toml in your favourite editor.

Finally, generate the chart to apply your changes to the configuration.

$ helmc generate --force tomcat

Cleanup

To delete the Tomcat deployment completely:

$ helmc uninstall -n default tomcat
