This repository holds a set of useful Docker base images:
| Image | Description |
|---|---|
| java | Java base images useful for microservices or JEE application servers |
| sti | Source-To-Image base image useful when running in OpenShift V3 |
| tomcat | Tomcat 5.5, 6 - 8 images (+ a STI variant) |
| jetty | Jetty 4 - 9 images (+ a STI variant) |
| karaf | Karaf 2.3 and 3 images |
The Docker build files for these images are generated by
fish-pepper, a sophisticated
template system for generation Docker builds. fish-pepper allows
the composition of various building block so that parametrized Docker
builds are easy possible.
In order to regenerate all Dockerfiles from the provided templates you
need only to install fish-pepper via npm (assuming that you have
node.js installed)
npm -g install fish-pepper
fish-pepper
The Java base images come in different flavors:
- Based on CentOS 7 or Alpine Linux (experimental)
- OpenJDK 7 or OpenJDK 8
- As JDK (Java Developer Toolkit) or as JRE (Java Runtime Environment)
All images have the following features:
- agent-bond is included which combines Jolokia and jmx_exporter
- A startup script
/run-java.shis included which transparently starts Java application provided as FAT-jar or traditionally with a bunch of jar dependencies.
How to use these images and what environment variables can be used are described in the associated README files.
STI builder images for OpenShift V3 come in two flavors, one based on CentOS 7 the other has RHEL 7 as base.
These images support also agent-bond and the same startup script as the vanilla Java images described above.
The README contains more details.
This project also provides images for various application servers which can be used out of the box.
All images are enabled with agent-bond since they are derived from the
base images described above. You can use the same environment
variables to setup the agents.
The following applicaton servers are supported:
