tag上、push上和pull 取Docker 映像,在此之前需要拥有一个docker Hub账户,注册地址:https://hub.docker.com/。
Tag、Push Docker映像
- 使用docker images 获取当前拥有的映像列表,其中可获取映像ID。
$ docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker-whale latest 7d9495d03763 38 minutes ago 273.7 MB <none> <none> 5dac217f722c 45 minutes ago 273.7 MB docker/whalesay latest fb434121fc77 4 hours ago 247 MB hello-world latest 91c95931e552 5 weeks ago 910 B
- 查找特定映像的ID,如 docker-whale:这个例子中的ID是:
7d9495d03763
。注意:’REPOSITORY
‘ 显示的是docker-whale的仓库名称,而不是命令空间,你需要将命令空间和你的Docker Hub账户联系起来,你的命令空间要和你的账户的账 户名称相同,因此将其重命名’YOUR_DOCKERHUB_NAME/docker-whale’ 。
$ docker tag 7d9495d03763 maryatdocker/docker-whale:latest
maryatdocker为自己的DockerHub账户。
- docker login命令用于在命令行中登录Docker Hub账户:
$ docker login Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one. Username: Password: Login Succeeded
- push 命令用于将映像推送到仓库当中:
$ docker push maryatdocker/docker-whale The push refers to a repository [maryatdocker/docker-whale] (len: 1) 7d9495d03763: Image already exists c81071adeeb5: Image successfully pushed eb06e47a01d2: Image successfully pushed fb434121fc77: Image successfully pushed 5d5bd9951e26: Image successfully pushed 99da72cfe067: Image successfully pushed 1722f41ddcb5: Image successfully pushed 5b74edbcaa5b: Image successfully pushed 676c4a1897e6: Image successfully pushed 07f8e8c5e660: Image successfully pushed 37bea4ee0c81: Image successfully pushed a82efea989f9: Image successfully pushed e9e06b06e14c: Image successfully pushed Digest: sha256:ad89e88beb7dc73bf55d456e2c600e0a39dd6c9500d7cd8d1025626c4b985011
Pull 获取最新创建的映像
使用docker rmi -f 强力移除本地已经存在的映像:
$ docker rmi -f 7d9495d03763 $ docker rmi -f docker-whale
PS:使用ID或者名称均可。
- 使用docker run 命令从仓库中拉取并载入映像:
docker run yourusername/docker-whale
PS:此处应该包含对应的Docker Hub账户名。
