Try to make a customized TorizonCore with Pre-provisioned Docker-Images

I think it is too much additional equipment and IT-Support only for a intermediate step without any really necessary functionality.

I think there’s a misconception here. It really requires no special equipment or setup to create a simple local registry. If you know what to do it takes maybe a minute at most. As an example here’s what many of our other customers do:

# This command starts a container that acts as a simple registry on your machine
$ docker run -d -p 5000:5000 --restart=always --name registry registry:2
# Now you can tag and push your image to this regisry like so
$ docker push localhost:5000/my-image
# Now with a compose file like this
$ cat docker-compose.yml 
version: '2.4'
    image: localhost:5000/my-image
# You can run the bundle command targeting this local registry
$ torizoncore-builder bundle --dind-param="--insecure-registry=localhost:5000" docker-compose.yml 
Creating Docker Container bundle...

Connecting to Docker Daemon at "tcp://"

It’s as simple as that. Most of the instructions regarding the local registry were adapted from the official Docker documentation here: Registry | Docker Docs
