1、前言
前提是现在有一个可以运行的docker 环境
2、docker image 的保存
# 查看要导出的image
[root@test neutron]# docker image list
REPOSITORY TAG IMAGE ID CREATED SIZE
192.168.10.12:5000/ustackrocky/centos-binary-neutron-server 5.0.5 2c8b39ecfa44 8 days ago 1.42 GB
# 导出image
[root@test neutron]# docker save 2c8b39ecfa44 > centos-binary-neutron-server.tar
# 查看已经导出的image
[root@test neutron]# ls centos-binary-neutron-server.tar
centos-binary-neutron-server.tar
3、docker image 的导入
# 将image导入到目标环境的本地设备上
[root@test neutron]# docker load < centos-binary-neutron-server.tar

# 查看目标环境本地设备上的image列表
[root@test neutron]# docker image list

4、打上目标环境的tag
[root@test neutron]# docker tag 2c8b39ecfa44 192.168.10.200:5000/ustackrocky/centos-binary-neutron-server:5.0.5
[root@test neutron]# docker image list

5、将本地的image上传到目标环境的docker 仓库
[root@test neutron]# docker push 2c8b39ecfa44 192.168.10.200:5000/ustackrocky/centos-binary-neutron-server:5.0.5
