Is there a way to combine all the dependent layers, I'd like to cut down on how long it takes to download an image

稍后更新。

Is there a way to pull a specific dependent layer:

不行,我找不到路。如果有人知道怎么做,请告诉我。

Can you revert a docker push?

有人在 https://groups.google.com/forum/#!topic/docker-user/wNHzbFv7cDw

中回答了

这是 Docker 的真正优势之一:能够返回到之前的提交。秘诀就是docker tag你想要的形象。

举个例子。在此示例中,我首先安装了 ping,然后提交,然后安装了 curl,并提交了。然后我回滚图像只包含 ping:

$ docker history imagename
IMAGE               CREATED             CREATED BY                SIZE

$ docker tag 2844 imagename   # <-- that's the secret right there

$ docker history imagename
IMAGE               CREATED             CREATED BY             SIZE
28445c70c2b3        56 seconds ago      apt-get install ping   11.57 MB
