+---
+
+# Kubernetes Secrets Engine
+
+The Kubernetes Secrets Engine for Vault generates Kubernetes service account tokens, and
+optionally service accounts, role bindings, and roles. The created service account tokens have
+a configurable TTL and any objects created are automatically deleted when the Vault lease expires.
+
+For each lease, Vault will create a service account token attached to the
+defined service account. The service account token is returned to the caller.
+
+To learn more about service accounts in Kubernetes, visit the
+[Kubernetes service account](https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/)
+and [Kubernetes RBAC](https://kubernetes.io/docs/reference/access-authn-authz/rbac/)
+documentation.
+
+~> **Note:** We do not recommend using tokens created by the Kubernetes Secrets Engine to
+   authenticate with the [Vault Kuberenetes Auth Method](/docs/auth/kubernetes). This will
+   generate many unique identities in Vault that will be hard to manage.
+
+## Setup
+
+The Kubernetes Secrets Engine must be configured in advance before it
+can perform its functions. These steps are usually completed by an operator or configuration
+management tool.
+
+1. By default, Vault will connect to Kubernetes using its own service account.
+   If using the [standard Helm chart](https://github.com/hashicorp/vault-helm), this service account
+   is created automatically by default and named after the Helm release (often `vault`, but this can be
+   configured via the Helm value `server.serviceAccount.name`).
+
+   It's necessary to ensure that the service account Vault uses will have permissions to manage
+   service account tokens, and optionally manage service accounts, roles, and role bindings. These
+   permissions can be managed using a Kuberentes role or cluster role. The role is attached to the
+   Vault service account with a role binding or cluster role binding.
+
+   For example, a minimal cluster role to create service account tokens is:
+   ```yaml
+   apiVersion: rbac.authorization.k8s.io/v1
+   kind: ClusterRole
+   metadata:
+     name: k8s-minimal-secrets-abilities
+   rules:
+   - apiGroups: [""]
+     resources: ["serviceaccounts/token"]
+     verbs: ["create"]
+   ```
+
+   Similarly, you can create a more permissive cluster role with full permissions to manage tokens,
+   service accounts, bindings, and roles.
+
+   ```yaml
+   apiVersion: rbac.authorization.k8s.io/v1
+   kind: ClusterRole
+   metadata:
+     name: k8s-full-secrets-abilities
+   rules:
+   - apiGroups: [""]
+     resources: ["serviceaccounts", "serviceaccounts/token"]
+     verbs: ["create", "update", "delete"]
+   - apiGroups: ["rbac.authorization.k8s.io"]
+     resources: ["rolebindings", "clusterrolebindings"]
+     verbs: ["create", "update", "delete"]
+   - apiGroups: ["rbac.authorization.k8s.io"]
+     resources: ["roles", "clusterroles"]
+     verbs: ["bind", "escalate", "create", "update", "delete"]
+   ```
+
+   Create this role in Kubernetes (e.g., with `kubectl apply -f`).
+
+   ~> **Note:** Getting the right permissions for Vault will require some trial and error most
+      likely since Kubernetes has strict protections against privilege escalation. You can read more
+      in the
+      [Kubernetes RBAC documentation](https://kubernetes.io/docs/reference/access-authn-authz/rbac/#privilege-escalation-prevention-and-bootstrapping).
+
+   ~> **Note:** Protect the Vault service account, especially if you use broader permissions for it,
+      as it is essentially a cluster administrator account.
+
+1. Create a role binding to bind the role to Vault's service account and grant Vault permission
+   to manage tokens.
+
+   ```yaml
+   apiVersion: rbac.authorization.k8s.io/v1
+   kind: ClusterRoleBinding
+   metadata:
+     name: vault-token-creator-binding
+   roleRef:
+     apiGroup: rbac.authorization.k8s.io
+     kind: ClusterRole
+     name: k8s-minimal-secrets-abilities
+   subjects:
+   - kind: ServiceAccount
+     name: vault
+     namespace: vault
+   ```
+
+   For more information on Kubernetes roles, service accounts, bindings, and tokens, visit the
+   [Kubernetes RBAC documentation](https://kubernetes.io/docs/reference/access-authn-authz/rbac/).
+
+1. If Vault will not be automatically managing roles or service accounts (see
+   [Automatically Managing Roles and Service Accounts](#automatically-managing-roles-and-service-accounts)),
+   then you will need to set up a service account that Vault will issue tokens for.
+
+   ~> **Note**: It is highly recommended that the service account that Vault issues tokens for
+      is **NOT** the same service account that Vault itself uses.
+
+   The examples we will use will under the namespace `test`, which you can create if it does not
+   already exist.
+
+   ```shell-session
+   $ kubectl create namespace test
+   namespace/test created
+   ```
+
+   Here is a simple set up of a service account, role, and role binding in the Kubernetes `test`
+   namespace with basic permissions we will use for this document:
+   ```yaml
+   apiVersion: v1
+   kind: ServiceAccount
+   metadata:
+     name: test-service-account-with-generated-token
+     namespace: test
+   ---
+   apiVersion: rbac.authorization.k8s.io/v1
+   kind: Role
+   metadata:
+     name: test-role-list-pods
+     namespace: test
+   rules:
+   - apiGroups: [""]
+     resources: ["pods"]
+     verbs: ["list"]
+   ---
+   apiVersion: rbac.authorization.k8s.io/v1
+   kind: RoleBinding
+   metadata:
+     name: test-role-abilities
+     namespace: test
+   roleRef:
+     apiGroup: rbac.authorization.k8s.io
+     kind: Role
+     name: test-role-list-pods
+   subjects:
+   - kind: ServiceAccount
+     name: test-service-account-with-generated-token
+     namespace: test
+   ```
+
+   You can create these objects with `kubectl apply -f`.
+
+1. Enable the Kubernetes Secrets Engine:
+
+   ```shell-session
+   $ vault secrets enable kubernetes
+   Success! Enabled the kubernetes Secrets Engine at: kubernetes/
+   ```
+
+   By default, the secrets engine will mount at the same name as the engine, i.e.,
+   `kubernetes/` here. This can be changed by passing the `-path` argument when enabling.
+
+1. Configure the mount point. An empty config is allowed.
+
+   ```shell-session
+   $ vault write -f kubernetes/config
+   ```
+
+   Configuration options are available as specified in the
+   [API docs](/api-docs/secret/kubernetes).
+
+1. You can now configure Kubernetes Secrets Engine to create a Vault role (**not** the same as a
+   Kubernetes role) that can generate service account tokens for the given service account:
+
+   ```shell-session
+   $ vault write kubernetes/roles/my-role \
+       allowed_kubernetes_namespaces="*" \
+       service_account_name="test-service-account-with-generated-token" \
+       token_default_ttl="10m"
+   ```
+
+## Generating Credentials
+
+After a user has authenticated to Vault and has sufficient permissions, a write to the
+`creds` endpoint for the Vault role will generate and return a new service account token.
+
+```shell-session
+$ vault write kubernetes/creds/my-role \
+    kubernetes_namespace=test
+
+Key                        Value
+–--                        -----
+lease_id                   kubernetes/creds/my-role/31d771a6-...
+lease_duration             10m0s
+lease_renwable             false
+service_account_name       test-service-account-with-generated-token
+service_account_namespace  test
+service_account_token      eyJHbGci0iJSUzI1NiIsImtpZCI6ImlrUEE...
+```
+
+You can use the service account token above (`eyJHbG...`) with any Kubernetes API request that
+its service account is authorized for (through role bindings).
+
+```shell-session
+$ curl -sk $(kubectl config view --minify -o 'jsonpath={.clusters[].cluster.server}')/api/v1/namespaces/test/pods \
+    --header "Authorization: Bearer eyJHbGci0iJSUzI1Ni..."
+{
+  "kind": "PodList",
+  "apiVersion": "v1",
+  "metadata": {
+    "resourceVersion": "1624"
+  },
+  "items": []
+}
+```
+
+When the lease expires, you can verify that the token has been revoked.
+```shell-session
+$ curl -sk $(kubectl config view --minify -o 'jsonpath={.clusters[].cluster.server}')/api/v1/namespaces/test/pods \
+    --header "Authorization: Bearer eyJHbGci0iJSUzI1Ni..."
+{
+  "kind": "Status",
+  "apiVersion": "v1",
+  "metadata": {},
+  "status": "Failure",
+  "message": "Unauthorized",
+  "reason": "Unauthorized",
+  "code": 401
+}
+```
+
+## TTL
+
+Kubernetes service account tokens have a time-to-live (TTL). When a token expires it is
+automatically revoked.
+
+You can set a default (`token_default_ttl`) and a maximum TTL (`token_max_ttl`) when
+creating or tuning the Vault role.
+
+```shell-session
+$ vault write kubernetes/roles/my-role \
+    allowed_kubernetes_namespaces="*" \
+    service_account_name="new-service-account-with-generated-token" \
+    token_default_ttl="10m" \
+    token_max_ttl="2h"
+```
+
+You can also set a TTL (`ttl`) when you generate the token from the credentials endpoint.
+The TTL of the token will be given the default if not specified (and cannot exceed the
+maximum TTL of the role, if present).
+
+```shell-session
+$ vault write kubernetes/creds/my-role \
+    kubernetes_namespace=test \
+    ttl=20m
+
+Key                        Value
+–--                        -----
+lease_id                   kubernetes/creds/my-role/31d771a6-...
+lease_duration             20m0s
+lease_renwable             false
+service_account_name       new-service-account-with-generated-token
+service_account_namespace  test
+service_account_token      eyJHbGci0iJSUzI1NiIsImtpZCI6ImlrUEE...
+```
+
+
+You can verify the token's TTL by decoding the JWT token and extracting the `iat`
+(issued at) and `exp` (expiration time) claims.
+
+```shell-session
+$ echo 'eyJhbGc...' | cut -d'.' -f2 | base64 -d  | jq -r '.iat,.exp|todate'
+2022-05-20T17:14:50Z
+2022-05-20T17:34:50Z
+```
+
+## Automatically Managing Roles and Service Accounts
+
+When configuring the Vault role, you can pass in parameters to specify that you want to
+automatically generate the Kubernetes service account and role binding,
+and optionally generate the Kubernetes role itself.
+
+If you want to configure the Vault role to use a pre-existing Kubernetes role, but generate
+the service account and role binding automatically, you can set the `kubernetes_role_name`
+parameter.
+
+```shell-session
+$ vault write kubernetes/roles/auto-managed-sa-role \
+    allowed_kubernetes_namespaces="test" \
+    kubernetes_role_name="test-role-list-pods"
+```
+
+~> **Note**: Vault's service account will also need access to the resources it is granting
+access to. This can be done for the examples above with `kubectl -n test create rolebinding --role test-role-list-pods --serviceaccount=vault:vault vault-test-role-abilities`.
+This is how Kuberentes prevents privilege escalation.
+You can read more in the
+[Kubernetes RBAC documentation](https://kubernetes.io/docs/reference/access-authn-authz/rbac/#privilege-escalation-prevention-and-bootstrapping).
+
+You can then get credentials with the automatically generated service account.
+```shell-session
+$ vault write kubernetes/creds/auto-managed-sa-role \
+    kubernetes_namespace=test
+Key                          Value
+---                          -----
+lease_id                     kubernetes/creds/auto-managed-sa-role/cujRLYjKZUMQk6dkHBGGWm67
+lease_duration               768h
+lease_renewable              false
+service_account_name         v-token-auto-man-1653001548-5z6hrgsxnmzncxejztml4arz
+service_account_namespace    test
+service_account_token        eyJHbGci0iJSUzI1Ni...
+```
+
+Furthermore, Vault can also automatically create the role in addition to the service account and
+role binding by specifying the `generated_role_rules` parameter, which accepts a set of JSON or YAML
+rules for the generated role.
+
+```shell-session
+$ vault write kubernetes/roles/auto-managed-sa-and-role \
+    allowed_kubernetes_namespaces="test" \
+    generated_role_rules='{"rules":[{"apiGroups":[""],"resources":["pods"],"verbs":["list"]}]}'
+```
+You can then get credentials in the same way as before.
+```shell-session
+$ vault write kubernetes/creds/auto-managed-sa-and-role \
+    kubernetes_namespace=test
+Key                          Value
+---                          -----
+lease_id                     kubernetes/creds/auto-managed-sa-and-role/pehLtegoTP8vCkcaQozUqOHf
+lease_duration               768h
+lease_renewable              false
+service_account_name         v-token-auto-man-1653002096-4imxf3ytjh5hbyro9s1oqdo3
+service_account_namespace    test
+service_account_token        eyJHbGci0iJSUzI1Ni...
+```
