Install the tools required for the following steps. + + - [Install kind](https://kind.sigs.k8s.io/docs/user/quick-start/), if not already installed. e.g. `brew install kind` on MacOS. + + - kind depends on Docker. If not already installed, [install Docker](https://docs.docker.com/get-docker/), e.g. `brew cask install docker` on MacOS. + + - This demo requires `kubectl`, which comes with Docker, or can be [installed separately](https://kubernetes.io/docs/tasks/tools/install-kubectl/). + + - This demo requires a tool capable of generating a `bcrypt` hash in order to interact with + the webhook. The example below uses `htpasswd`, which is installed on most macOS systems, and can be + installed on some Linux systems via the `apache2-utils` package (e.g., `apt-get install + apache2-utils`). + + - One of the steps below optionally uses `jq` to help find the latest release version number. It is not required. + Install `jq` if you would like, e.g. `brew install jq` on MacOS. + +1. Create a new Kubernetes cluster using `kind create cluster`. Optionally provide a cluster name using the `--name` flag. + kind will automatically update your kubeconfig to point to the new cluster as a user with admin-like permissions. + +1. Query GitHub's API for the git tag of the latest Pinniped + [release](https://github.com/vmware-tanzu/pinniped/releases/latest). + + ```bash + pinniped_version=$(curl https://api.github.com/repos/vmware-tanzu/pinniped/releases/latest -s | jq .name -r) + ``` + + Alternatively, [any release version](https://github.com/vmware-tanzu/pinniped/releases) + number can be manually selected. + + ```bash + # Example of manually choosing a release version... + pinniped_version=v0.2.0 + ``` + +1. Deploy the local-user-authenticator app. This is a demo identity provider. In production, you would use your + real identity provider, and therefore would not need to deploy or configure local-user-authenticator. + + ```bash + kubectl apply -f https://github.com/vmware-tanzu/pinniped/releases/download/$pinniped_version/install-local-user-authenticator.yaml + ``` + + The `install-local-user-authenticator.yaml` file includes the default deployment options. + If you would prefer to customize the available options, please + see [deploy/local-user-authenticator/README.md](https://github.com/vmware-tanzu/pinniped/blob/main/deploy/local-user-authenticator/README.md) + for instructions on how to deploy using `ytt`. + +1. Create a test user named `pinny-the-seal` in the local-user-authenticator identity provider. + + ```bash + kubectl create secret generic pinny-the-seal \ + --namespace local-user-authenticator \ + --from-literal=groups=group1,group2 \ + --from-literal=passwordHash=$(htpasswd -nbBC 10 x password123 | sed -e "s/^x://") + ``` + +1.

Create a `WebhookAuthenticator` object to configure Pinniped to authenticate using local-user-authenticator. + + ```bash + cat < /tmp/pinniped-kubeconfig + ``` + + If you are using MacOS, you may get an error dialog that says + `“pinniped” cannot be opened because the developer cannot be verified`. Cancel this dialog, open System Preferences, + click on Security & Privacy, and click the Allow Anyway button next to the Pinniped message. + Run the above command again and another dialog will appear saying + `macOS cannot verify the developer of “pinniped”. Are you sure you want to open it?`. + Click Open to allow the command to proceed. + + Note that the above command will print a warning to the screen. You can ignore this warning. + Pinniped tries to auto-discover the URL for the Kubernetes API server, but it is not able + to do so on kind clusters. The warning is just letting you know that the Pinniped CLI decided + to ignore the auto-discovery URL and instead use the URL from your existing kubeconfig. + +1. Try using the generated kubeconfig to issue arbitrary `kubectl` commands as + the `pinny-the-seal` user. + + ```bash + kubectl --kubeconfig /tmp/pinniped-kubeconfig get pods -n pinniped-concierge + ``` + + Because this user has no RBAC permissions on this cluster, the previous command + results in the error `Error from server (Forbidden): pods is forbidden: User "pinny-the-seal" cannot list resource "pods" in API group "" in the namespace "pinniped"`. + However, this does prove that you are authenticated and acting as the `pinny-the-seal` user. + +1. As the admin user, create RBAC rules for the test user to give them permissions to perform actions on the cluster. + For example, grant the test user permission to view all cluster resources. + + ```bash + kubectl create clusterrolebinding pinny-can-read --clusterrole view --user pinny-the-seal + ``` + +1.

Carry on issuing as many `kubectl` commands as you'd like as the `pinny-the-seal` user. + Each invocation will use Pinniped for authentication. + You may find it convenient to set the `KUBECONFIG` environment variable rather than passing `--kubeconfig` to each invocation. + + ```bash + export KUBECONFIG=/tmp/pinniped-kubeconfig + kubectl get namespaces + kubectl get pods -A + ``` + +1.
