Docker base build with all dev utilities under /opt/ including all versions of JDK's we use. Works as a good base image for Bamboo server since the directories are correct for what it or an agent expects by default.
As per https://confluence.atlassian.com/display/BAMBOO/stock+images
See Dockerfile for which software from that list is installed. But it looks something like this...
Oracle JDK 6, 7, 8 installed to default locations, and also symlinked from /opt/jdk-6, /opt/jdk-7, /opt/jdk-8 as Bamboo expects. Open JDK 6, 7 as well. All dev tools under /opt where Bamboo likes them:
