创建Dockerfile

• JDK

FROM docker.io/jeanblanchard/alpine-glibc
ADD ./package/jdk-8u201-linux-x64.tar.gz /usr/local/docker/java/jdk/
ENV JAVA_HOME=/usr/local/docker/java/jdk/jdk1.8.0_201
ENV CLASSPATH=$JAVA_HOME/bin
ENV PATH=.:$JAVA_HOME/bin:$PATH
CMD ["java","-version"]

• JRE

# using apline-glibc instead of apline is mainly because JDK relies on glibc
FROM docker.io/jeanblanchard/alpine-glibc
# add jdk
ADD ./package/jre-8u201-linux-x64.tar.gz /usr/local/docker/java/jdk/
# env
ENV JAVA_HOME=/usr/local/docker/java/jdk/jre1.8.0_201
ENV CLASSPATH=$JAVA_HOME/bin
ENV PATH=.:$JAVA_HOME/bin:$PATH
# workdir
WORKDIR /opt
# cmd
CMD ["java","-version"]
