	## Prerequisite

	### Directories

	```
	sudo mkdir -p /srv/softwareheritage-kube/dev/{objects,storage-db,scheduler-db,kafka,web-db,prometheus,zookeeper/data,zookeeper/datalog,grafana,elasticsearch,redis,registry,idx-storage-db,vault-db,vault-cache,deposit-db,deposit-cache}
	sudo chown 1000:1000 /srv/softwareheritage-kube/dev/{objects,elasticsearch,vault-cache,deposit-cache}
	sudo chown -R 999:999 /srv/softwareheritage-kube/dev/*-db
	sudo chown 472:0 /srv/softwareheritage-kube/dev/grafana
	sudo chown nobody:nogroup /srv/softwareheritage-kube/dev/prometheus
	```

	### Registry

	- Add the following line on your `/etc/hosts` file. It's needed to be able to
	push the image to it from docker
	```
	127.0.0.1 registry.default
	```
	- Start the registry in kubernetes
	```
	kubectl apply -f kubernetes/registry/00-registry.yml
	```

	If you are using k3s, the registry must be declared on the
	`/etc/rancher/k3s/registries.yaml` as it's insecure:

	```
	mirrors:
	registry.default:
	endpoint:
	- "http://registry.default/v2/"
	```

	## Build the base image

	```
	cd docker
	docker build --no-cache -t swh/stack .

	docker tag swh/stack:latest registry.default/swh/stack:latest
	docker push registry.default/swh/stack:latest
	```

	## Development

	To access the services, they must be declared on the `/etc/hosts` file:
	```
	-127.0.0.1 objstorage.default storage.default webapp.default scheduler.default rabbitmq.default grafana.default prometheus.default counters.default registry-ui idx-storage.default vault.default deposit.default
	+127.0.0.1 objstorage.default storage.default webapp.default scheduler.default rabbitmq.default grafana.default prometheus.default counters.default registry-ui.default idx-storage.default vault.default deposit.default
	```

	### Skaffold

	To start the development environment using skaffold, use the following command:

	```
	skaffold --default-repo registry.default dev
	```

	It will build the images, deploy them on the local registry and start the services.
	It will monitor the projects to detect the changes and restart the containers when needed

	## Basic commands

	Hint: Use tabulation to ease finding out new commands

	- List pods:
	```
	$ kubectl get pods
	NAME READY STATUS RESTARTS AGE
	registry-deployment-7595868dc8-657ps 1/1 Running 0 46m
	objstorage-8587d58b68-76jbn 1/1 Running 0 12m
	```

	- List services:

	```
	$ kubectl get services objstorage
	NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
	objstorage ClusterIP 10.43.185.191 <none> 5003/TCP 17m
	```

	- Check service is responding:

	```
	$ curl http://$(kubectl get services objstorage -o jsonpath='{.spec.clusterIP}'):5003
	SWH Objstorage API server%

	$ curl http://$(kubectl get services scheduler -o jsonpath='{.spec.clusterIP}'):5008

	```

	- Force a pod to redeploy itself

	```
	kubectl delete pod storage-db-<tab>-<tab>
	```

	- Clean up registry due to too much disk space used

	```
	kubectl exec -ti $(kubectl get pods --no-headers -l app=registry \| grep -i running \| awk '{print $1}) -- /bin/registry garbage-collect -m /etc/docker/registry/config.yml
	```
