In this example, we will walk through how to set up the Kubernetes Auth Method.

This assumes the following commands will be run inside a Vault pod running in Kubernetes.

Exec into the Vault pod:

kubectl exec -it vault-0 -- /bin/sh

If you didn't set server.dev.enabled=true, you'll need to log in to Vault first using vault login. Then run the following commands to configure the Kubernetes Auth Method:

vault auth enable kubernetes
vault write auth/kubernetes/config \
    kubernetes_host=https://$KUBERNETES_SERVICE_HOST:$KUBERNETES_SERVICE_PORT

From here you can continue to configure Vault from the Kubernetes Auth Method documentation.
