将Docker映像发送到Docker Hub并使用python将其标记为最新

如何解决将Docker映像发送到Docker Hub并使用python将其标记为最新

我正在尝试将doccer图像发送到docker hub中的帐户并使用python对其进行标记

这是我到目前为止所取得的成就：

import docker

client = docker.from_env()
img = client.images.pull('Nginx:latest')
contanier = client.containers.run(img,detach=True,ports={'80/tcp': 8080})
# Here I am trying to send the image to my account (docker hub account) and tag it as the latest 

我正在努力寻找一种方法，将映像发送到docker hub中的帐户并将其标记为最新版本。

解决方法

正如@DavidMaze所述，您应该真正尝试阅读并阅读其文档。

我-出于好奇-几个月前有同样的问题。我问自己是否可以用Python做到这一点。但是，我不想坐着等待答复，所以我从没问过这个问题，因此我仔细阅读了他们的文档和源代码以完成任务。

注意：此示例可能不起作用。将其作为您自己的研究/实施的起点。欢迎编辑/评论此答案！

免责声明：：这是对my very own experimentation结果的快速而肮脏的复制/清除。

Before starting,you will need a `.env` file with the following:

编辑1：我忘记了您的标记部分：-）

这里是如何将图像标记为latest。

DOCKER_API_CLIENT.tag(
    image,"xxx/xxx(repository)",tag=latest
)

编辑2：链接

这是我使用/写过的东西的官方链接。

• DOCKER_API_CLIENT.push()

• DOCKER_API_CLIENT.login()

• DOCKER_API_CLIENT.tag()

我希望这对某人有帮助！
