+    This is a kubectl plugin for Kubernetes OpenID Connect (OIDC) authentication.
+
+    ## Credential plugin mode
+    kubectl executes oidc-login before calling the Kubernetes APIs.
+    oidc-login automatically opens the browser and you can log in to the provider.
+    After authentication, kubectl gets the token from oidc-login and you can access the cluster.
+    See https://github.com/int128/kubelogin#credential-plugin-mode for more.
+
+    ## Standalone mode
+    Run `kubectl oidc-login`.
+    It automatically opens the browser and you can log in to the provider.
+    After authentication, it writes the token to the kubeconfig and you can access the cluster.
+    See https://github.com/int128/kubelogin#standalone-mode for more.
+
+  caveats: |
+    You need to setup the OIDC provider, Kubernetes API server, role binding and kubeconfig.

 This is a kubectl plugin for [Kubernetes OpenID Connect (OIDC) authentication](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#openid-connect-tokens), also known as `kubectl oidc-login`.
 
-This is designed to run as a [client-go credential plugin](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#client-go-credential-plugins).
+Here is an example of Kubernetes authentication with the Google Identity Platform:
+
+<img alt="screencast" src="https://user-images.githubusercontent.com/321266/85427290-86e43700-b5b6-11ea-9e97-ffefd736c9b7.gif" width="572" height="391">
+
+Kubelogin is designed to run as a [client-go credential plugin](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#client-go-credential-plugins).
 When you run kubectl, kubelogin opens the browser and you can log in to the provider.
 Then kubelogin gets a token from the provider and kubectl access Kubernetes APIs with the token.
+Take a look at the diagram:

-### CA Certificates
-
-You can use your self-signed certificate for the provider.
-
-```yaml
-      - --certificate-authority=/home/user/.kube/keycloak-ca.pem
-```
-
-### HTTP Proxy
-
-You can set the following environment variables if you are behind a proxy: `HTTP_PROXY`, `HTTPS_PROXY` and `NO_PROXY`.
-See also [net/http#ProxyFromEnvironment](https://golang.org/pkg/net/http/#ProxyFromEnvironment).
+You can verify kubelogin works with your provider using [acceptance test](acceptance_test).
 
 
-### Authentication flows
+## Docs
 
-#### Authorization code flow
-
-Kubelogin performs the authorization code flow by default.
-
-It starts the local server at port 8000 or 18000 by default.
-You need to register the following redirect URIs to the provider:
-
-- `http://localhost:8000`
-- `http://localhost:18000` (used if port 8000 is already in use)
-
-You can change the ports by the option:
-
-```yaml
-      - --listen-port 12345
-      - --listen-port 23456
-```
-
-#### Resource owner password credentials grant flow
-
-As well as you can use the resource owner password credentials grant flow.
-Keycloak supports this flow but you need to explicitly enable the "Direct Access Grants" feature in the client settings.
-Most OIDC providers do not support this flow.
-
-You can pass the username and password:
-
-```yaml
-      - --username USERNAME
-      - --password PASSWORD
-```
-
-If the password is not set, kubelogin will show the prompt.
-
-```
-% kubelogin --username USER
-Password:

+
+This is a manual test for verifying Kubernetes OIDC authentication with your OIDC provider.
+
+
+## Purpose
+
+This test checks the following points:
+
+1. You can set up your OIDC provider using [setup guide](../docs/setup.md).
+1. The plugin works with your OIDC provider.
+
+
+## Getting Started
+
+### Prerequisite
+
+You need to build the plugin into the parent directory.
+
+```sh
+make -C ..
+```
+
+You need to set up your provider.
+See [setup guide](../docs/setup.md) for more.
+
+You need to install the following tools:
+
+- Docker
+- Kind
+- kubectl
+
+You can check if the tools are available.
+
+```sh
+make check
+```
+
+### 1. Create a cluster
+
+Create a cluster.
+For example, you can create a cluster with Google account authentication.
+
+```sh
+make OIDC_ISSUER_URL=https://accounts.google.com \
+  OIDC_CLIENT_ID=REDACTED.apps.googleusercontent.com \
+  OIDC_CLIENT_SECRET=REDACTED \
+  YOUR_EMAIL=REDACTED@gmail.com
+```
+
+It will do the following steps:
+
+1. Create a cluster.
+1. Set up access control. It allows read-only access from your email address.
+1. Set up kubectl to enable the plugin.
+
+You can change kubectl configuration in generated `output/kubeconfig.yaml`.
+
+### 2. Run kubectl
+
+Make sure you can log in to the provider and access the cluster.
+
+```console
+% export KUBECONFIG=$PWD/output/kubeconfig.yaml
+% kubectl get pods -A
+```
+
+### Clean up
+
+To delete the cluster and generated files:
+
+```sh
+make delete-cluster
+make clean
+```

+# Kubernetes OpenID Connection authentication
+
+This document guides how to set up Kubernetes OpenID Connect (OIDC) authentication.
+Let's see the following steps:
+
+1. Set up the OIDC provider
+1. Verify authentication
+1. Bind a cluster role
+1. Set up the Kubernetes API server
+1. Set up the kubeconfig
+1. Verify cluster access
+
+
+## 1. Set up the OIDC provider
+
+### Google Identity Platform
+
+You can log in with a Google account.
+
+Open [Google APIs Console](https://console.developers.google.com/apis/credentials) and create an OAuth client with the following setting:
+
+- Application Type: Other
+
+Check the client ID and secret.
+Replace the following variables in the later sections.
+
+Variable                | Value
+------------------------|------
+`ISSUER_URL`            | `https://accounts.google.com`
+`YOUR_CLIENT_ID`        | `xxx.apps.googleusercontent.com`
+`YOUR_CLIENT_SECRET`    | random string
+
+### Keycloak
+
+You can log in with a user of Keycloak.
+Make sure you have an administrator role of the Keycloak realm.
+
+Open Keycloak and create an OIDC client as follows:
+
+- Client ID: `YOUR_CLIENT_ID`
+- Valid Redirect URLs:
+    - `http://localhost:8000`
+    - `http://localhost:18000` (used if the port 8000 is already in use)
+- Issuer URL: `https://keycloak.example.com/auth/realms/YOUR_REALM`
+
+You can associate client roles by adding the following mapper:
+
+- Name: `groups`
+- Mapper Type: `User Client Role`
+- Client ID: `YOUR_CLIENT_ID`
+- Client Role prefix: `kubernetes:`
+- Token Claim Name: `groups`
+- Add to ID token: on
+
+For example, if you have `admin` role of the client, you will get a JWT with the claim `{"groups": ["kubernetes:admin"]}`.
+
+Replace the following variables in the later sections.
+
+Variable                | Value
+------------------------|------
+`ISSUER_URL`            | `https://keycloak.example.com/auth/realms/YOUR_REALM`
+`YOUR_CLIENT_ID`        | `YOUR_CLIENT_ID`
+`YOUR_CLIENT_SECRET`    | random string
+
+### Dex with GitHub
+
+You can log in with a GitHub account.
+
+Open [GitHub OAuth Apps](https://github.com/settings/developers) and create an application with the following setting:
+
+- Application name: (any)
+- Homepage URL: `https://dex.example.com`
+- Authorization callback URL: `https://dex.example.com/callback`
+
+Deploy [Dex](https://github.com/dexidp/dex) with the following config:
+
+```yaml
+issuer: https://dex.example.com
+connectors:
+- type: github
+  id: github
+  name: GitHub
+  config:
+    clientID: YOUR_GITHUB_CLIENT_ID
+    clientSecret: YOUR_GITHUB_CLIENT_SECRET
+    redirectURI: https://dex.example.com/callback
+staticClients:
+- id: YOUR_CLIENT_ID
+  name: Kubernetes
+  redirectURIs:
+  - http://localhost:8000
+  - http://localhost:18000
+  secret: YOUR_DEX_CLIENT_SECRET
+```
+
+Replace the following variables in the later sections.
+
+Variable                | Value
+------------------------|------
+`ISSUER_URL`            | `https://dex.example.com`
+`YOUR_CLIENT_ID`        | `YOUR_CLIENT_ID`
+`YOUR_CLIENT_SECRET`    | `YOUR_DEX_CLIENT_SECRET`
+
+### Okta
+
+You can log in with an Okta user.
+Okta supports [the authorization code flow with PKCE](https://developer.okta.com/docs/guides/implement-auth-code-pkce/overview/)
+and this section explains how to set up it.
+
+Open your Okta organization and create an application with the following options:
+
+- Application type: Native
+- Initiate login URI: `http://localhost:8000`
+- Login redirect URIs:
+    - `http://localhost:8000`
+    - `http://localhost:18000` (used if the port 8000 is already in use)
+- Allowed grant types: Authorization Code
+- Client authentication: Use PKCE (for public clients)
+
+Replace the following variables in the later sections.
+
+Variable                | Value
+------------------------|------
+`ISSUER_URL`            | `https://YOUR_ORGANIZATION.okta.com`
+`YOUR_CLIENT_ID`        | random string
+
+You do not need to set `YOUR_CLIENT_SECRET`.
+
+If you need `groups` claim for access control,
+see [jetstack/okta-kubectl-auth](https://github.com/jetstack/okta-kubectl-auth/blob/master/docs/okta-setup.md) and [#250](https://github.com/int128/kubelogin/issues/250).
+
+### Ping Identity
+
+Login with an account that has permissions to create applications.
+Create an OIDC application with the following configuration:
+
+- Redirect URIs:
+    - `http://localhost:8000`
+    - `http://localhost:18000` (used if the port 8000 is already in use)
+- Grant type: Authorization Code
+- PKCE Enforcement: Required
+
+Leverage the following variables in the next steps.
+
+Variable                | Value
+------------------------|------
+`ISSUER_URL`            | `https://auth.pingone.com/<PingOne Tenant Id>/as`
+`YOUR_CLIENT_ID`        |  random string
+
+`YOUR_CLIENT_SECRET` is not required for this configuration.
+
+## 2. Verify authentication
+
+Run the following command:
+
+```sh
+kubectl oidc-login setup \
+  --oidc-issuer-url=ISSUER_URL \
+  --oidc-client-id=YOUR_CLIENT_ID \
+  --oidc-client-secret=YOUR_CLIENT_SECRET
+```
+
+It launches the browser and navigates to `http://localhost:8000`.
+Please log in to the provider.
+
+You can set extra options, for example, extra scope or CA certificate.
+See also the full options.
+
+```sh
+kubectl oidc-login setup --help
+```
+
+
+## 3. Bind a cluster role
+
+Here bind `cluster-admin` role to you.
+
+```sh
+kubectl create clusterrolebinding oidc-cluster-admin --clusterrole=cluster-admin --user='ISSUER_URL#YOUR_SUBJECT'
+```
+
+As well as you can create a custom cluster role and bind it.
+
+
+## 4. Set up the Kubernetes API server
+
+Add the following flags to kube-apiserver:
+
+```
+--oidc-issuer-url=ISSUER_URL
+--oidc-client-id=YOUR_CLIENT_ID
+```
+
+See [Kubernetes Authenticating: OpenID Connect Tokens](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#openid-connect-tokens) for the all flags.
+
+If you are using [kops](https://github.com/kubernetes/kops), run `kops edit cluster` and append the following settings:
+
+```yaml
+spec:
+  kubeAPIServer:
+    oidcIssuerURL: ISSUER_URL
+    oidcClientID: YOUR_CLIENT_ID
+```
+
+If you are using [kube-aws](https://github.com/kubernetes-incubator/kube-aws), append the following settings to the `cluster.yaml`:
+
+```yaml
+       oidc:
+         enabled: true
+         issuerUrl: ISSUER_URL
+         clientId: YOUR_CLIENT_ID
+```
+
+
+## 5. Set up the kubeconfig
+
+Add `oidc` user to the kubeconfig.
+
+```sh
+kubectl config set-credentials oidc \
+  --exec-api-version=client.authentication.k8s.io/v1beta1 \
+  --exec-command=kubectl \
+  --exec-arg=oidc-login \
+  --exec-arg=get-token \
+  --exec-arg=--oidc-issuer-url=ISSUER_URL \
+  --exec-arg=--oidc-client-id=YOUR_CLIENT_ID \
+  --exec-arg=--oidc-client-secret=YOUR_CLIENT_SECRET
+```
+
+
+## 6. Verify cluster access
+
+Make sure you can access the Kubernetes cluster.
+
+```sh
+kubectl --user=oidc cluster-info
+```
+
+You can switch the current context to oidc.
+
+```sh
+kubectl config set-context --current --user=oidc
+```
+
+You can share the kubeconfig to your team members for on-boarding.

+```
+
+
+## Options
+
+### Authentication timeout
+
+By default, you need to log in to your provider in the browser within 3 minutes.
+This prevents a process from remaining forever.
+You can change the timeout by the following flag:
+
+```yaml
+      - --authentication-timeout-sec=60
+```
+
+For now this timeout works only for the authorization code flow.
+
+### Extra scopes
+
+You can set the extra scopes to request to the provider by `--oidc-extra-scope`.
+
+```yaml
+      - --oidc-extra-scope=email
+      - --oidc-extra-scope=profile
+```
+
+### CA certificate
+
+You can use your self-signed certificate for the provider.
+
+```yaml
+      - --certificate-authority=/home/user/.kube/keycloak-ca.pem
+      - --certificate-authority-data=LS0t...
+```
+
+### HTTP proxy
+
+You can set the following environment variables if you are behind a proxy: `HTTP_PROXY`, `HTTPS_PROXY` and `NO_PROXY`.
+See also [net/http#ProxyFromEnvironment](https://golang.org/pkg/net/http/#ProxyFromEnvironment).
+
+### Home directory expansion
+
+If a value in the following options begins with a tilde character `~`, it is expanded to the home directory.
+
+- `--certificate-authority`
+- `--local-server-cert`
+- `--local-server-key`
+- `--token-cache-dir`
+
+
+## Authentication flows
+
+Kubelogin support the following flows:
+
+- Authorization code flow
+- Authorization code flow with a keyboard
+- Resource owner password credentials grant flow
+
+### Authorization code flow
+
+Kubelogin performs the authorization code flow by default.
+
+It starts the local server at port 8000 or 18000 by default.
+You need to register the following redirect URIs to the provider:
+
+- `http://localhost:8000`
+- `http://localhost:18000` (used if port 8000 is already in use)
+
+You can change the listening address.
+
+```yaml
+      - --listen-address=127.0.0.1:12345
+      - --listen-address=127.0.0.1:23456
+```
+
+You can specify a certificate for the local webserver if HTTPS is required by your identity provider.
+
+```yaml
+      - --local-server-cert=localhost.crt
+      - --local-server-key=localhost.key
+```
+
+You can change the hostname of redirect URI from the default value `localhost`.
+
+```yaml
+      - --oidc-redirect-url-hostname=127.0.0.1
+```
+
+You can add extra parameters to the authentication request.
+
+```yaml
+      - --oidc-auth-request-extra-params=ttl=86400
+```
+
+When authentication completed, kubelogin shows a message to close the browser.
+You can change the URL to show after authentication.
+
+```yaml
+      - --open-url-after-authentication=https://example.com/success.html
+```
+
+You can skip opening the browser if you encounter some environment problem.
+
+```yaml
+      - --skip-open-browser
+```
+
+For Linux users, you change the default browser by `BROWSER` environment variable.
+
+### Authorization code flow with a keyboard
+
+If you cannot access the browser, instead use the authorization code flow with a keyboard.
+
+```yaml
+      - --grant-type=authcode-keyboard
+```
+
+Kubelogin will show the URL and prompt.
+Open the URL in the browser and then copy the code shown.
+
+```
+% kubectl get pods
+Open https://accounts.google.com/o/oauth2/v2/auth?access_type=offline&client_id=...
+Enter code: YOUR_CODE
+```
+
+Note that this flow uses the redirect URI `urn:ietf:wg:oauth:2.0:oob` and some OIDC providers do not support it.
+
+You can add extra parameters to the authentication request.
+
+```yaml
+      - --oidc-auth-request-extra-params=ttl=86400
+```
+
+### Resource owner password credentials grant flow
+
+Kubelogin performs the resource owner password credentials grant flow
+when `--grant-type=password` or `--username` is set.
+
+Note that most OIDC providers do not support this flow.
+Keycloak supports this flow but you need to explicitly enable the "Direct Access Grants" feature in the client settings.
+
+You can set the username and password.
+
+```yaml
+      - --username=USERNAME
+      - --password=PASSWORD
+```
+
+If the password is not set, kubelogin will show the prompt for the password.
+
+```yaml
+      - --username=USERNAME
+```
+
+```
+% kubectl get pods
+Password:
+```
+
+If the username is not set, kubelogin will show the prompt for the username and password.
+
+```yaml
+      - --grant-type=password
+```
+
+```
+% kubectl get pods
+Username: foo
+Password:
+```
+
+## Run in Docker
+
+You can run [the Docker image](https://ghcr.io/int128/kubelogin) instead of the binary.
+The kubeconfig looks like:
+
+```yaml
+users:
+- name: oidc
+  user:
+    exec:
+      apiVersion: client.authentication.k8s.io/v1beta1
+      command: docker
+      args:
+      - run
+      - --rm
+      - -v
+      - /tmp/.token-cache:/.token-cache
+      - -p
+      - 8000:8000
+      - ghcr.io/int128/kubelogin
+      - get-token
+      - --token-cache-dir=/.token-cache
+      - --listen-address=0.0.0.0:8000
+      - --oidc-issuer-url=ISSUER_URL
+      - --oidc-client-id=YOUR_CLIENT_ID
+      - --oidc-client-secret=YOUR_CLIENT_SECRET
+```
+
+Known limitations:
+
+- It cannot open the browser automatically.
+- The container port and listen port must be equal for consistency of the redirect URI.

-  description: |
-    This is a kubectl plugin for Kubernetes OpenID Connect (OIDC) authentication.
-
-    ## Credential plugin mode
-    kubectl executes oidc-login before calling the Kubernetes APIs.
-    oidc-login automatically opens the browser and you can log in to the provider.
-    After authentication, kubectl gets the token from oidc-login and you can access the cluster.
-    See https://github.com/int128/kubelogin#credential-plugin-mode for more.
-
-    ## Standalone mode
-    Run `kubectl oidc-login`.
-    It automatically opens the browser and you can log in to the provider.
-    After authentication, it writes the token to the kubeconfig and you can access the cluster.
-    See https://github.com/int128/kubelogin#standalone-mode for more.
-
-  caveats: |
-    You need to setup the OIDC provider, Kubernetes API server, role binding and kubeconfig.
