Camel Apache CI simulated environment

Dockerfile

###
# How to build the container:
#
# To create a container that uses OpenJDK:
# docker build --build-arg CI_USER=$(whoami) --target ci-openjdk --tag ci-openjdk .
#
# To create a container that uses Oracle JDK (as in CI):
# 1. First download the Oracle JDK from the Oracle web site (ie.: jdk-11.0.9_linux-x64_bin.tar.gz)
#
# 2. Then build the container with:
# docker build --build-arg CI_USER=$(whoami) --target ci-oracle-jdk --tag ci-oracle-jdk .
# 
# Note: there are other parameters that can be configured, like JDK version, but they are untested.
###
# How to run the container:
#
# You have to mount the local source code dir on the container and also mount the maven
# repository and settings. To do so, run:
#
# docker run -it -v $HOME/code/java/camel:/home/$(whoami)/code -v $HOME/.m2/repository:/home/$(whoami)/.m2/repository -v $HOME/.m2/settings.xml:/home/$(whoami)/.m2/settings.xml:ro -u $(whoami):$(whoami) --privileged ci-openjdk:latest
