Noobaa on Kubernetes Hands On

1. Start minikube:

minikube start

2. Work with minikube's internal docker - useful for development so you don't need to constantly push\pull images

eval $(minikube docker-env)
# test by listing images - you'll see all kind of k8s images
docker images

3. build noobaa server image - first download rpm from jenkins and copy to noobaa.rpm under noobaa-core, then run docker build

docker build -f ./src/deploy/NVA_build/Server.Dockerfile -t nbserver --rm --no-cache ./

4. tag the image

docker tag nbserver nbserver:1

5. update noobaa_core.yaml to point to the image we just built

image: nbserver:1

6. deploy noobaa yaml file in kubernetes

kubectl apply -f src/deploy/NVA_build/noobaa_core.yaml

7. check that statefulset\service\pods are created

kubectl get statefulset
kubectl get pod
kubectl get service

8. getting into the noobaa server

kubectl exec -it noobaa-server-0 /bin/bash

9. connecting to the system from outside the cluster can be done by connecting to the service ip and the mapped port (can be found with kubectl get service)
   another option is to forward ports 80 and 8080 from kuberentes to local host

sudo kubectl port-forward noobaa-server-0 80:80 8080:8080

10. creating agents - copy agents yaml from the UI to a file and use kubectl apply -f [agents.yaml]

Noobaa Operator

1. build the operator. you must have go and dep installed. this will build a noobaa-operator image

./src/deploy/build_operator.sh

2. tag the operator image

docker tag noobaa-operator noobaa-operator:1

2. deploy the operator yaml in the cluster

kubectl create -f ./gocode/src/noobaa-operator/deploy/noobaa-operator.yaml

3. deploy a noobaa resource in kuberentes

kubectl create -f src/deploy/NVA_build/noobaa.yaml

4. another way to run the operator (mainly during the development of the operator itself) is locally on the laptop, instead of building an image and deploying to kubernetes

operator-sdk up local --namespace=default

AWS-CLI

You can use aws-cli easily from another pod using the service internal dns name: <service>.<namespace>.svc.cluster.local which is in minikube case noobaa-services.default.svc.cluster.local.

For example you could run the following:

kubectl run aws-cli -it --rm \
  --generator=run-pod/v1 \
  --image=mesosphere/aws-cli \
  --env="AWS_ACCESS_KEY_ID=123" \
  --env="AWS_SECRET_ACCESS_KEY=abc" \
  -- --endpoint-url http://noobaa-services.default.svc.cluster.local \
  s3api list-buckets
