feat: add default_source
This PR introduces a default_source
for dockerTest
which we use to pull all images from.
By default the source is set to Local
, requiring the all the images to exist on the local system.
The user can also supply a default_source
, as of now we only support dockerhub
as a remote source.
In the future, we envisage that the user can supply a private or public registry and credentials to access it.
We still allow the user to provide a source per image, this will override the default_source
.
