Best answer would be use docker official java image. Dockerfile
If you still want your own image with Java home set. Add this lines to your Dockerfile
RUN apt-get update && \
apt-get install -y openjdk-8-jdk && \
apt-get install -y ant && \
apt-get clean && \
rm -rf /var/lib/apt/lists/ && \
rm -rf /var/cache/oracle-jdk8-installer;
ENV JAVA_HOME /usr/lib/jvm/java-8-openjdk-amd64/
RUN export JAVA_HOME
