Deployment

Save our Docker registry in $REGISTRY (so we don't have to type it over and over): export REGISTRY=[[HOST_SUBDOMAIN]]-5000-[[KATACODA_HOST]].environments.katacoda.com

Build and tag our image: docker build -t $REGISTRY/web-server:1.0

Push our image to our registry: docker push $REGISTRY/web-server:1.0
