QuickNote — Docker Load vs Docker Import

As usual here is what I have been burnt with today.

Docker import and Docker load from a brief glance do the same thing, however there is one big difference.

Docker import does not include the cmd to imitate the container. Docker load does. I am unsure if there is anything else. This means that when you run a docker image that has been imported you need to specify the exec command. In kubernetes this will give you a CreateContainerError.

so instead of

docker import package.tgz customname:customtag

use

docker load -i package.tgz

and then retag the image if required.
