Using images from the Docker Hub

• For everyone's convenience, we took care of building DockerCoins images

• We pushed these images to the DockerHub, under the dockercoins user

• These images are tagged with a version number, v0.1

• The full image names are therefore:

  • dockercoins/hasher:v0.1

  • dockercoins/rng:v0.1

  • dockercoins/webui:v0.1

  • dockercoins/worker:v0.1

---

Setting $REGISTRY and $TAG

• In the upcoming exercises and labs, we use a couple of environment variables:

  • $REGISTRY as a prefix to all image names

  • $TAG as the image version tag

• For example, the worker image is $REGISTRY/worker:$TAG

• If you copy-paste the commands in these exercises:

  make sure that you set $REGISTRY and $TAG first!

• For example:

  export REGISTRY=dockercoins TAG=v0.1
  

  (this will expand $REGISTRY/worker:$TAG to dockercoins/worker:v0.1)
