Issue
I'm working on a dockerfile.
I just realised that I've been using FROM
with indexed images all along.
So I wonder:
- How can I use one of my local (custom) images as my base (
FROM
) image withoutpushing
it to the index?
Solution
You can use it without doing anything special. If you have a local image called blah
you can do FROM blah
. If you do FROM blah
in your Dockerfile, but don't have a local image called blah
, then Docker will try to pull it from the registry.
In other words, if a Dockerfile does FROM ubuntu
, but you have a local image called ubuntu
different from the official one, your image will override it.
