+# Kubernetes and Helm Container
+
+This sample dev container allows you to work with Kubernetes clusters and use the Kubernetes extension from within the container! 
+
+The container includes the kubectl for Kubernetes, Helm, and the Docker CLI and can be easily set up to work with a local Minikube install. Just follow the steps below for your operating system.
+
+
+## macOS Setup
+
+1. Install "Docker Desktop for Mac" locally if you have not.
+
+2. Start Docker, right-click on the Docker icon and select "Preferences..."
+
+3. Check **Kubernetes > Enable Kubernetes**
+
+4. Open this folder in VS Code
+
+5. Edit `.vscode/devConatiner.json` and change `$HOME` in the last item in the `runArgs` array to the absolute path of your home folder. e.g.
+    ```
+    "runArgs": ["-e", "SYNC_LOCALHOST_KUBECONFIG=true",
+        "-v","/var/run/docker.sock:/var/run/docker.sock", 
+        "-v", "/Users/clantz/.kube:/root/.kube-localhost"]
+    ```
+    > **Note:** Resolving [vscode-remote#670](https://github.com/Microsoft/vscode-remote/issues/670) will remove this step.
+
+6. Run the **Remote: Reopen folder in Container** command. Once connected, you should see your clusters in the Kubernetes explorer.
+
+7. [Optional] If you want to use [Helm](https://helm.sh), open a VS Code terminal and run:
+    ```
+    helm init
+    ```
+
+## Windows Setup
+
+1. Install "Docker Desktop for Windows" locally if you have not.
+   
+2. Right Click on Docker system tray icon and select "Settings"
+   
+3. Check **General > "Expose daemon on tcp://localhost:2375 without TLS"**
+
+4. Check **Kubernetes > Enable Kubernetes**
+   
+5. Open this folder in VS Code
+
+6. Edit `.vscode/devConatiner.json` replace the **entire** contents `runArgs` of with the following. Replace `C:\\Users\\clantz\\` with the path your your user directory.
+    ```
+    "runArgs": ["-e", "SYNC_LOCALHOST_KUBECONFIG=true",
+        "-e", "DOCKER_HOST=tcp://host.docker.internal:2375",         
+        "-v", "C:\\Users\\clantz\\.kube:/root/.kube-localhost"]
+    ```
+    > **Note:** Resolving [vscode-remote#670](https://github.com/Microsoft/vscode-remote/issues/670) and [vscode-remote#669](https://github.com/Microsoft/vscode-remote/issues/669) will remove this step.
+
+7. Run the **Remote: Reopen folder in Container** command. Once connected, you should see your clusters in the Kubernetes explorer.
+
+8. [Optional] If you want to use [Helm](https://helm.sh), open a VS Code terminal and run:
+    ```
+    helm init
+    ```
+
+## Linux Setup
+
+1. Install [Docker CE](https://docs.docker.com/install/linux/docker-ce/ubuntu/), [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/), and [Minikube](https://kubernetes.io/docs/tasks/tools/install-minikube/) on your local OS if you have not already.
+
+2. Start Minikube as follows:
+    ```
+    minikube start
+    kubectl config set-context minikube
+    ```
+
+4. Open this folder in VS Code
+
+5. Edit `.vscode/devConatiner.json` and change `$HOME` in the last item in the `runArgs` array to the absolute path of your home folder. e.g.
+    ```
+    "runArgs": ["-e", "SYNC_LOCALHOST_KUBECONFIG=true",
+        "-v","/var/run/docker.sock:/var/run/docker.sock", 
+        "-v", "/home/clantz/.kube:/root/.kube-localhost"]
+    ```
+    > **Note:** Resolving [vscode-remote#670](https://github.com/Microsoft/vscode-remote/issues/670) will remove this step.
+
+6. Run the **Remote: Reopen folder in Container** command. Once connected, you should see your clusters in the Kubernetes explorer.
+
+7. [Optional] If you want to use [Helm](https://helm.sh), open a VS Code terminal and run:
+    ```
+    helm init
+    ```
