+title: Deploy a Hyperledger Besu private network locally with Kubernetes
+description: Deploying a Hyperledger Besu private network locally with Kubernetes
+---
+
+# Deploy Besu with Kubernetes in a Local Environment
+
+The [playground](https://github.com/ConsenSys/quorum-kubernetes/tree/master/playground) was created to provide an
+opportunity to deploy [quorum-kubernetes](https://github.com/ConsenSys/quorum-kubernetes/) in a local environment before
+attempting in a live environment (such as in the cloud or on-premise).
+Local deployment can be done with any local Kubernetes tool.
+Minikube and Rancher Desktop have been tested to work, but any complete Kubernetes solution with support for `kubectl`
+should suffice.
+
+## How to deploy locally
+
+1. Navigate to the playground [`README`](https://github.com/ConsenSys/quorum-kubernetes/tree/master/playground).
+1. Ensure that your system meets the requirements specified.
+1. Choose your Ethereum client (Hyperledger Besu or GoQuorum): `quorum-besu` or `quorum-go`.
+1. Choose your consensus algorithm.
+   The playground supports Clique, Ethash (PoW), and IBFT2 for Besu, and IBFT for GoQuorum.
+1. Follow the instructions from the `README` for the chosen client and consensus algorithm folder.
+
+## Important notes
+
+Consider the following when deploying and developing with the playground:
+
+* The playground is created specifically for developers and operators to become familiar with the deployment of Besu in
+  a Kubernetes environment in preparation for going into a cloud or on-premise environment.
+  Thus, it should **not** be deployed into a production environment.
+* The playground is not a complete reflection of the `dev` and `prod` charts as it does not use `Helm`, but rather
+  static or non-templated code that is deployed through `kubectl apply -f`.
+  This means that without `Helm` there's a significant amount of repeated code.
+  This is fine for development but not ideal for a production environment.
+* The playground uses static/hard-coded keys.
+  Automatic key generation is only supported in `dev` and `prod` charts.
+* As the playground is for local development, no cloud integration or lifecycle support is offered.
