Docker容器跨服务器迁移步骤【测试成功】

一、需求背景

    云服务器A马上就过期了，上面部署了很多docker容器，需要将其迁移到云服务器B，后续通过B服务器进行访问。

二、操作步骤

    1、在A服务器上,使用docker save命令将pengzhile/pandora容器保存为文件:

docker save -o pengzhile-pandora.tar pengzhile/pandora

    2、将生成的pengzhile-pandora.tar文件复制到B服务器上,可以使用scp命令或者其他文件传输方式。

    3、在B服务器上加载该镜像文件。

docker load -i pengzhile-pandora.tar

  4、在B服务器启动容器,并使用与源服务器相同的挂载和端口映射选项:

       将容器内8899端口映射到主机的18899端口

docker run  -e PANDORA_CLOUD=cloud -e PANDORA_SERVER=0.0.0.0:8899 -p 18899:8899 -d pengzhile/pandora

5、检查目标服务器上新的容器是否运行正常。
