 # Chainlink cluster
+
 Example CL nodes cluster for system level tests
 
 Install `kubefwd` (no nixpkg for it yet, planned)
+
 ```
 brew install txn2/tap/kubefwd
 ```
+
 If you want to build images you need [docker](https://docs.docker.com/engine/install/) service running
 
 Enter the shell (from the root project dir)
+
 ```
 nix develop
 ```
 
 # Develop
 
 ## New cluster
+
 We are using [devspace](https://www.devspace.sh/docs/getting-started/installation?x0=3)
 
 Configure the cluster, see `deployments.app.helm.values` and [values.yaml](./values.yaml) comments for more details
 
 Set up your K8s access
+
 ```
 export DEVSPACE_IMAGE="..."
 ./setup.sh ${my-personal-namespace-name-crib}
 ```
 
 Create a .env file based on the .env.sample file
+
 ```sh
 cp .env.sample .env
 # Fill in the required values in .env
 ```

 Default `ttl` is `72h`, use `ttl` command to update if you need more time
 
 Valid values are `1h`, `2m`, `3s`, etc. Go time format is invalid `1h2m3s`

 ```
 devspace run ttl ${namespace} 120h

 Forward ports to check UI or run tests
+
 ```
 devspace run connect ${my-personal-namespace-name-crib}
 ```
 
+List ingress hostnames
+
+```
+devspace run ingress-hosts
+```
+
 Destroy the cluster
+
 ```
 devspace purge
 ```
 
 ## Running load tests
+
 Check this [doc](../../integration-tests/load/ocr/README.md)
 
 If you used `devspace dev ...` always use `devspace reset pods` to switch the pods back
 
 # Helm
+
 If you would like to use `helm` directly, please uncomment data in `values.yaml`
+
 ## Install from local files
+
 ```
 helm install -f values.yaml cl-cluster .
 ```
+
 Forward all apps (in another terminal)
+
 ```
 sudo kubefwd svc -n cl-cluster
 ```
+
 Then you can connect and run your tests
 
 ## Install from release
+
 Add the repository
+
 ```
 helm repo add chainlink-cluster https://raw.githubusercontent.com/smartcontractkit/chainlink/helm-release/
 helm repo update
 ```
+
 Set default namespace
+
 ```
 kubectl create ns cl-cluster
 kubectl config set-context --current --namespace cl-cluster
 ```
 
 Install
+
 ```
 helm install -f values.yaml cl-cluster .
 ```
 
 ## Create a new release
+
 Bump version in `Chart.yml` add your changes and add `helm_release` label to any PR to trigger a release
 
 ## Helm Test
+
 ```
 helm test cl-cluster
 ```
 
 ## Uninstall
+
 ```
 helm uninstall cl-cluster
 ```
