+# Usage
+
+`setup-local-s3.sh [BUCKET_NAME]`:
+- [BUCKET_NAME] is optional, "mybucket" will be used if not specified
+- sets up a k3s instance
+- installs a localstack pod
+- creates http and https routing to localstack via localhost
+- saves the self-signed certificate as ca.crt
+- uses the certificate to initialize a restic repo at `https://k3stesthost/BUCKET_NAME`
+
+Note: In case of not being able to connect to "k3stesthost/health", you might need to ensure that the ingress' ip matches with the required host names: k3stesthost and cloudhost. With `sudo k3s kubectl get ingress` you can view the ingress' ip (e.g. 10.0.2.15), then add a line to file "/etc/hosts" e.g. `10.0.2.15	k3stesthost cloudhost`
+
+`start-k3s.sh`:
+- creates and starts a k3s instance
+
+`k3s-uninstall.sh`:
+- deletes everything k3s related
+
+## Other useful commands
+- `sudo k3s kubectl get pods`
+- `curl k3stesthost/health`
+  expected: `{"services": {"s3": "running"}, "features": {"persistence": "disabled", "initScripts": "initialized"}}` 
+
+#### Requires AWS-CLI
+- create bucket `aws --endpoint-url=http://k3stesthost s3 mb s3://mybucket`
+- list buckets `aws --endpoint-url=http://k3stesthost s3 ls`
+- upload something `aws --endpoint-url=http://k3stesthost s3 cp test.txt s3://mybucket`
+- check files `aws --endpoint-url=http://k3stesthost s3 ls s3://mybucket`
+
+## Run docker locally
+
+
+```
+docker pull docker:19.03.12-dind
+docker run -d --privileged --name integration-test docker:19.03.12-dind
+docker exec integration-test sh -c "apk add bash"
+
+```
+
+Set up docker container integration-test:
+
+```
+docker cp  ../../../../../c4k-nextcloud/ integration-test:/
+docker exec -it integration-test sh
+cd /c4k-nextcloud/src/test/resources/local-integration-test
+./setup-docker.sh
+```
+
+## Deploy nextcloud 
+
+### Requirements
+
+* leiningen (install with: `sudo apt install leiningen` )
+* In the project's root execute: `lein uberjar`
+* Change file "valid-config.edn" according to your settings (e.g. `:fqdn "cloudhost"` and `:restic-repository "s3://k3stesthost:mybucket"`).
+
+### Deploy to k3s
+
+* Create and deploy the k8s yaml:
+`java -jar target/uberjar/c4k-nextcloud-standalone.jar valid-config.edn valid-auth.edn | sudo k3s kubectl apply -f -`
+
+Some of the steps may take some min to be effective, but eventually nextcloud should be available at: https://cloudhost
+
+### Deploy to k3d
+
+k3d is a k3s system which is running inside of a container. To install k3d run `curl -s https://raw.githubusercontent.com/rancher/k3d/main/install.sh | bash` or have a look at https://k3d.io/v5.0.3/ .
+
+* Start a k3d cluster to deploy s3, nextcloud and test backup and restore on it: `./setup-local-s3-on-k3d.sh`
+
+Some steps may take a couple of minutes to be effective, but eventually nextcloud should be available at: https://cloudhost
+
+#### Remove k3d cluster
+
+`k3d cluster delete nextcloud`
+
+## Test in local gitlab runner
+
+See https://stackoverflow.com/questions/32933174/use-gitlab-ci-to-run-tests-locally
+
+This needs to be done in the project root
+
+`docker run -d --name gitlab-runner --restart always -v $PWD:$PWD -v /var/run/docker.sock:/var/run/docker.sock gitlab/gitlab-runner:latest`
+
+`docker exec -it -w $PWD gitlab-runner gitlab-runner exec docker nextcloud-integrationtest --docker-privileged --docker-volumes '/var/run/docker.sock:/var/run/docker.sock'`
