制作Oracle11g Docker 镜像

基于Linux系统，宿主主机要设置如下环境变量，oracle为64位版本
dockerfile中需要的数据库安装包可从csdn下载内找到

生成镜像及发布容器流程：

# 新建镜像重新发布流程
# 停止正在运行的容器, 如果之前存在失败安装可运行此步骤
docker stop oracle11g

# 删除容器, 如果之前存在失败安装可运行此步骤
docker rm oracle11g

# 列出所有镜像，找到镜像ID, 如果之前存在失败安装可运行此步骤
docker images

# 删除镜像（使用镜像名称或ID）, 如果之前存在失败安装可运行此步骤
docker rmi oracle11g-xe

# 在包含Dockerfile的目录中执行
docker build -t oracle11g-xe .

# 启动容器
docker run -d \
  --name oracle11g \
  --privileged \
  --shm-size=1g \
  -p 1521:1521 \
  -p 8080:8080 \
  -v oracle_data:/u01/app/oracle/oradata \
  oracle11g-xe

# 查看容器日志
docker logs -f oracle11g  

# 在容器内连接
docker exec -it oracle11g sqlplus system/oracle@localhost:1521/ORCL

# 从宿主机连接
sqlplus system/oracle@localhost:1521/ORCL

# 导出oracle镜像
docker save -o oracle11g.tar oracle11g-xe
