@itaysk also I was wondering if we could do something like this:
Basically, use the image that you would like to pull directly but set an environment variable to make sure your application shuts-down (or does never actually start). This way the image should get pulled too I guess?
Update: Okay, this appears to work but I'd prefer the other way. Using
env
is just a bit ugly.
