docker - commit、publish、transmis

提交container定制镜像

sudo docker commit -m '修改的信息' container_name image_name:tag

上传镜像到仓库

• 上传镜像->repository（！如果该repository不存在的话，会自动创建）

$ sudo docker images 
REPOSITORY                  TAG                 IMAGE ID            CREATED             SIZE
mgm_db                      base                96244ef9009e        5 hours ago         544.3 MB

# 打tag，注意格式：用户名/repository_name:TAG
$ sudo docker tag 96 xiaochonghao/mgm_db:v0

# push镜像到xiaochonghao用户的mgm_db仓库中，如果xiaochonghao/mgm_db在仓库中不存在，则执行这条命令他过程中会自动创建repository
$ sudo docker push xiaochonghao/mgm_db:v0
The push refers to a repository [docker.io/xiaochonghao/mgm_db]

不通过docker pub账号，在主机之间传输镜像

• You will need to save the docker image as a tar file:

  # 这里的image name可以随便起名字
  docker save -o <save image to path> <image name>
  

• copy image to new system with scp

  ex:
  scp /tmp/oss_web_image root@10.13.2.133:/tmp/
  

• load the image into docker

  docker load -i <path to image tar file>
