a way to pull docker image from host #29

Open jgallen23 opened 9 years ago

jgallen23 commented 9 years ago

I have a base docker image for my dev setup and if I type rebuild it builds from that. The problem is I regularly update that image, but rebuild isn't pulling latest, so I have to log into host machine and manually pull and then rebuild. Any thoughts on making this easier? I'd be happy to submit a pull request, but I wanted to discuss first in case something was planned already

So pulling latest on your base image that your Dockerfile references? That's tricky. I'd like to expose the host docker to admin users, and that would help in these situations ... except unless you wanted to do this for non-admin users. Hmm, I'd hate to slowly expose every Docker command.

Yes, pulling latest on the base image manually inside the host right now. When I do a rebuild inside of an environment, it picks up the changes, but if I don't pull manually, it just rebuilds the previously pulled version. I guess if I tagged my images as different versions, it would solve it, but right now docker hub is auto building and tagging as latest every time.

I was thinking of a "force" option for rebuild that would force rebuild instead of using any cached layers. I suppose it could be worth doing a pull on the FROM image in that case as well.
