使用Debian 11基础镜像制作java8镜像

下面是dockerfile内容：

FROM debian:bullseye

# 切换apt源为清华源，并安装vim ping telnet命令
RUN apt-get update && apt install -y apt-transport-https ca-certificates && \
cp /etc/apt/sources.list /etc/apt/sources.list.bak  && \
echo "deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye main contrib non-free" > /etc/apt/sources.list && \
echo "deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-updates main contrib non-free" >> /etc/apt/sources.list && \
echo "deb https://mirrors.tuna.tsinghua.edu.cn/debian/ bullseye-backports main contrib non-free" >> /etc/apt/sources.list && \
echo "deb https://mirrors.tuna.tsinghua.edu.cn/debian-security bullseye-security main contrib non-free" >> /etc/apt/sources.list && \
apt-get clean && apt-get update && apt-get install -y vim iputils-ping telnet

# 拷贝java、arthas包
ADD jdk-8u371-linux-x64.tar.gz arthas-boot.jar /opt

# 配置java环境变量
RUN echo 'export JAVA_HOME=/opt/jdk1.8.0_371/' >> /etc/profile && \
echo 'export JRE_HOME=/opt/jdk1.8.0_371/jre' >> /etc/profile && \
echo 'export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib:$JRE_HOME/lib' >> /etc/profile && \
echo 'export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin' >> /etc/profile && \
echo 'source /etc/profile' >> /root/.bashrc
