Docker Registry Example

docker-reg-example.sh

# create a docker machine and run the registry on it
docker-machine create -d virtualbox box1
docker $(docker-machine config box1) run -d -p 5000:5000 --restart=always --name registry registry:2

# create the second docker machine referencing the insecure registry
docker-machine create -d virtualbox --engine-insecure-registry $(docker-machine ip box1):5000 box2

# on the second docker machine pull an image, login to the insecure registry (entry any login/password), tag, push the image, and then run the image
docker $(docker-machine config box2) pull alpine
docker $(docker-machine config box2) login $(docker-machine ip box1):5000
docker $(docker-machine config box2) tag alpine $(docker-machine ip box1):5000/myalpine
docker $(docker-machine config box2) push $(docker-machine ip box1):5000/myalpine
docker $(docker-machine config box2) run --rm -it $(docker-machine ip box1):5000/myalpine sh

# create a third docker machine referencing the insecure registry (skipped login here because the registry is insecure, but for a secured registry you would need to login first)
docker-machine create -d virtualbox --engine-insecure-registry $(docker-machine ip box1):5000 box3
docker $(docker-machine config box3) run --rm -it $(docker-machine ip box1):5000/myalpine sh
