Creates review apps. Tested with minikube.
minikube start
minikube addon enable ingress
minikube addon enable registry
kubectl --namespace=kube-system port-forward service/registry 80:5000If you want to poke around in the dashboard:
minikube addon enable dashboard
minikube dashboardIn one terminal:
cd example-app
eval "$(minikube docker-env)"
docker build -t localhost:5000/example:master .
docker push localhost:5000/example:masterIn another terminal:
cd review-app
npm ci
node . example masterIn one terminal:
cd example-app
# ... after making changes to index.html ...
eval "$(minikube docker-env)"
docker build -t localhost:5000/example:some-feature .
docker push localhost:5000/example:some-featureIn another terminal:
cd review-app
node . example some-featureIf the above instructions have gone well, you should have a pair of ingresses created for minikube:
$ kubectl --namespace=review get ingress
NAME HOSTS ADDRESS PORTS AGE
example-master master.example.review.app 192.168.122.141 80 93s
example-some-feature some-feature.example.review.app 192.168.122.141 80 91sYou can verify that the apps are running side-by-side by curling the ingress IP and overriding the host:
$ curl -H 'Host: master.example.review.app' http://192.168.122.141/

Objects are tagged with repo, branch, and tag metadata. (repo and branch are forced lowercase due to Kubernetes naming restrictions.)
# To delete a single review app:
kubectl delete svc,deployments,ingress -l app=example-some-feature
# To blow away an entire repo's apps:
kubectl delete svc,deployments,ingress -l repo=example
