centos7镜像创建可以ssh链接的Docker容器

一、Dockerfile

# 指定基础镜像
FROM centos:7
# 配置环境变量和本地软件
ENV PACKGE_DIR=/usr/local

# j安装包放在和Dockerfile同级目录下
ENV JAVA_PACKGE=jdk-8u181-linux-x64.tar.gz
ENV NODEJS_PACKGE=node-v16.20.0-linux-x64.tar.gz
ENV PYTHON_PACKGE=Python-3.9.6.tar.xz

# 拷贝安装包
COPY ./$JAVA_PACKGE $PACKGE_DIR
COPY ./$NODEJS_PACKGE $PACKGE_DIR
COPY ./$PYTHON_PACKGE $PACKGE_DIR
