-  shortDescription: Log in to the OpenID Connect provider
-  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.

+This is a kubectl plugin for [Kubernetes OpenID Connect (OIDC) authentication](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#openid-connect-tokens).
+It gets a token from the OIDC provider and writes it to the kubeconfig.

-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:
-
-![Diagram of the credential plugin](docs/credential-plugin-diagram.svg)

 ## Getting Started

-### Setup
+You need to setup the following components:

-Install the latest release from [Homebrew](https://brew.sh/), [Krew](https://github.com/kubernetes-sigs/krew), [Chocolatey](https://chocolatey.org/packages/kubelogin) or [GitHub Releases](https://github.com/int128/kubelogin/releases).
+- OIDC provider
+- Kubernetes API server
+- Role for your group or user
+- kubectl authentication
+
+You can install the latest release from [Homebrew](https://brew.sh/), [Krew](https://github.com/kubernetes-sigs/krew) or [GitHub Releases](https://github.com/int128/kubelogin/releases) as follows:

 ```sh
-# Homebrew (macOS and Linux)
+# Homebrew
+brew tap int128/kubelogin
 brew install kubelogin

-# Krew (macOS, Linux, Windows and ARM)
+# Krew
 kubectl krew install oidc-login

-# Chocolatey (Windows)
-choco install kubelogin
+# GitHub Releases
+curl -LO https://github.com/int128/kubelogin/releases/download/v1.9.1/kubelogin_linux_amd64.zip
+unzip kubelogin_linux_amd64.zip
+ln -s kubelogin kubectl-oidc_login
 ```

-If you install via GitHub releases, save the binary as the name `kubectl-oidc_login` on your path.
-When you invoke `kubectl oidc-login`, kubectl finds it by the [naming convention of kubectl plugins](https://kubernetes.io/docs/tasks/extend-kubectl/kubectl-plugins/).
-The other install methods do this for you.
+After initial setup or when the token has been expired, just run:

-You need to set up the OIDC provider, cluster role binding, Kubernetes API server and kubeconfig.
-Your kubeconfig looks like this:
-
-```yaml
-users:
-  - name: oidc
-    user:
-      exec:
-        apiVersion: client.authentication.k8s.io/v1
-        command: kubectl
-        args:
-          - oidc-login
-          - get-token
-          - --oidc-issuer-url=ISSUER_URL
-          - --oidc-client-id=YOUR_CLIENT_ID
+```
+% kubelogin
+Using current-context: hello.k8s.local
+Open http://localhost:8000 for authorization
+Got a token for subject 0123456789 (valid until 2019-04-12 11:00:49 +0900 JST)
+Updated ~/.kube/config
 ```

-See the [setup guide](docs/setup.md) for more.
+or run as a kubectl plugin:

-### Run
+```
+% kubectl oidc-login
+```

-Run kubectl.
+It opens the browser and you can log in to the provider.
+After authentication, it gets an ID token and refresh token and writes them to the kubeconfig.
+
+For more, see the following documents:
+
+- [Getting Started with Keycloak](docs/keycloak.md)
+- [Getting Started with Google Identity Platform](docs/google.md)
+- [Team Operation](docs/team_ops.md)
+
+
+## Configuration
+
+This supports the following options.
+
+```
+  kubelogin [OPTIONS]
+
+Application Options:
+      --kubeconfig=               Path to the kubeconfig file (default: ~/.kube/config) [$KUBECONFIG]
+      --listen-port=              Port used by kubelogin to bind its webserver (default: 8000) [$KUBELOGIN_LISTEN_PORT]
+      --insecure-skip-tls-verify  If set, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure
+                                  [$KUBELOGIN_INSECURE_SKIP_TLS_VERIFY]
+      --skip-open-browser         If set, it does not open the browser on authentication. [$KUBELOGIN_SKIP_OPEN_BROWSER]
+  -v, --v=                        If set to 1 or greater, show debug log (default: 0)
+
+Help Options:
+  -h, --help        Show this help message
+```
+
+This also supports the following keys of `auth-provider` in kubeconfig.
+See [kubectl authentication](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#using-kubectl).
+
+Key | Direction | Value
+----|-----------|------
+`idp-issuer-url`                  | Read (Mandatory) | Issuer URL of the provider.
+`client-id`                       | Read (Mandatory) | Client ID of the provider.
+`client-secret`                   | Read (Mandatory) | Client Secret of the provider.
+`idp-certificate-authority`       | Read | CA certificate path of the provider.
+`idp-certificate-authority-data`  | Read | Base64 encoded CA certificate of the provider.
+`extra-scopes`                    | Read | Scopes to request to the provider (comma separated).
+`id-token`                        | Write | ID token got from the provider.
+`refresh-token`                   | Write | Refresh token got from the provider.
+
+
+### Kubeconfig path
+
+You can set the environment variable `KUBECONFIG` to point the config file.
+Default to `~/.kube/config`.

 ```sh
-kubectl get pods
+export KUBECONFIG="$PWD/.kubeconfig"
 ```

-Kubectl executes kubelogin before calling the Kubernetes APIs.
-Kubelogin automatically opens the browser, and you can log in to the provider.

-After the authentication, kubelogin returns the credentials to kubectl.
-Kubectl then calls the Kubernetes APIs with the credentials.
+### Extra scopes

-```console
-% kubectl get pods
-Open http://localhost:8000 for authentication
-NAME                          READY   STATUS    RESTARTS   AGE
-echoserver-86c78fdccd-nzmd5   1/1     Running   0          26d
+You can set extra scopes to request to the provider by `extra-scopes` in the kubeconfig.
+
+```sh
+kubectl config set-credentials keycloak --auth-provider-arg extra-scopes=email
 ```

-Kubelogin stores the ID token and refresh token to the cache.
-If the ID token is valid, it just returns it.
-If the ID token has expired, it will refresh the token using the refresh token.
-If the refresh token has expired, it will perform re-authentication.
+Note that kubectl does not accept multiple scopes and you need to edit the kubeconfig as like:

-## Troubleshooting
-
-### Token cache
-
-Kubelogin stores the token cache to the file system by default.
-For enhanced security, it is recommended to store it to the keyring.
-See the [token cache](docs/usage.md#token-cache) for details.
-
-You can log out by deleting the token cache.
-
-```console
-% kubectl oidc-login clean
-Deleted the token cache at /home/user/.kube/cache/oidc-login
-Deleted the token cache from the keyring
+```sh
+kubectl config set-credentials keycloak --auth-provider-arg extra-scopes=SCOPES
+sed -i '' -e s/SCOPES/email,profile/ $KUBECONFIG
 ```

-Kubelogin will ask you to log in via the browser again.
-If the browser has a cookie for the provider, you need to log out from the provider or clear the cookie.

-### ID token claims
+### CA Certificates

-You can run `setup` command to dump the claims of an ID token from the provider.
+You can set your self-signed certificates for the OIDC provider (not Kubernetes API server) by `idp-certificate-authority` and `idp-certificate-authority-data` in the kubeconfig.

-```console
-% kubectl oidc-login setup --oidc-issuer-url=ISSUER_URL --oidc-client-id=REDACTED
-...
-You got a token with the following claims:
-
-{
-  "sub": "********",
-  "iss": "https://accounts.google.com",
-  "aud": "********",
-  ...
-}
+```sh
+kubectl config set-credentials keycloak \
+  --auth-provider-arg idp-certificate-authority=$HOME/.kube/keycloak-ca.pem
 ```

-You can set `-v1` option to increase the log level.
+If kubelogin could not parse the certificate, it shows a warning and skips it.

-```yaml
-users:
-  - name: oidc
-    user:
-      exec:
-        apiVersion: client.authentication.k8s.io/v1
-        command: kubectl
-        args:
-          - oidc-login
-          - get-token
-          - -v1
-```

-You can run the [acceptance test](acceptance_test) to verify if kubelogin works with your provider.
+### HTTP Proxy

-## Docs
+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).

-# kubelogin/acceptance_test
-
-This is a manual test to verify if the Kubernetes OIDC authentication works with your OIDC provider.
-
-## Purpose
-
-This test checks the following points:
-
-1. You can set up your OIDC provider using the [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 the [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 \
-  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
-
-Kubelogin supports the authentication flows such as Device Authorization Grant or Authorization Code Flow.
-For the details of flows supported in Kubelogin, see the [usage](usage.md).
-For the details of your provider, ask the administrator of your provider.
-
-## 2. Authenticate with the OpenID Connect Provider
-
-Run the following command to show the instruction to set up the configuration:
-
-```sh
-kubectl oidc-login setup --oidc-issuer-url=ISSUER_URL --oidc-client-id=YOUR_CLIENT_ID
-```
-
-Set the following flags:
-
- Set the issuer URL of your OpenID Connect provider to `--oidc-issuer-url`.
- Set the client ID for your OpenID Connect provider to `--oidc-client-id`.
- If your provider requires a client secret, set `--oidc-client-secret`.
-
-If your provider supports the Device Authorization Grant, set `--grant-type=device-code`.
-It launches the browser and navigates to the authentication page of your provider.
-
-If your provider supports the Authorization Code Flow, set `--grant-type=authcode`.
-It starts a local server for the authentication.
-It launches the browser and navigates to the authentication page of your provider.
-
-You can see the full options:
-
-```sh
-kubectl oidc-login setup --help
-```
-
-## 3. Bind a cluster role
-
-You can run the following command to bind `cluster-admin` role to you:
-
-```sh
-kubectl create clusterrolebinding oidc-cluster-admin --clusterrole=cluster-admin --user='ISSUER_URL#YOUR_SUBJECT'
-```
-
-## 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.
-
-## 5. Set up the kubeconfig
-
-Add `oidc` user to the kubeconfig.
-
-```sh
-kubectl config set-credentials oidc \
-  --exec-interactive-mode=Never \
-  --exec-api-version=client.authentication.k8s.io/v1 \
-  --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
-```
-
-If your provider requires a client secret, add `--oidc-client-secret=YOUR_CLIENT_SECRET`.
-
-For security, it is recommended to add `--token-cache-storage=keyring` to store the token cache to the keyring instead of the file system.
-If you encounter an error, see the [token cache](usage.md#token-cache) for details.
-
-## 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.

-# Standalone mode
-
-Kubelogin supports the standalone mode as well.
-It writes the token to the kubeconfig (typically `~/.kube/config`) after authentication.
-
-## Getting started
-
-Configure your kubeconfig like:
-
-```yaml
- name: keycloak
-  user:
-    auth-provider:
-      config:
-        client-id: YOUR_CLIENT_ID
-        client-secret: YOUR_CLIENT_SECRET
-        idp-issuer-url: https://issuer.example.com
-      name: oidc
-```
-
-Run kubelogin:
-
-```sh
-kubelogin
-
-# or run as a kubectl plugin
-kubectl oidc-login
-```
-
-It automatically opens the browser and you can log in to the provider.
-
-<img src="keycloak-login.png" alt="keycloak-login" width="455" height="329">
-
-After authentication, kubelogin writes the ID token and refresh token to the kubeconfig.
-
-```console
-% kubelogin
-Open http://localhost:8000 for authentication
-You got a valid token until 2019-05-18 10:28:51 +0900 JST
-Updated ~/.kubeconfig
-```
-
-Now you can access the cluster.
-
-```console
-% kubectl get pods
-NAME                          READY   STATUS    RESTARTS   AGE
-echoserver-86c78fdccd-nzmd5   1/1     Running   0          26d
-```
-
-Your kubeconfig looks like:
-
-```yaml
-users:
-  - name: keycloak
-    user:
-      auth-provider:
-        config:
-          client-id: YOUR_CLIENT_ID
-          client-secret: YOUR_CLIENT_SECRET
-          idp-issuer-url: https://issuer.example.com
-          id-token: ey... # kubelogin will add or update the ID token here
-          refresh-token: ey... # kubelogin will add or update the refresh token here
-        name: oidc
-```
-
-If the ID token is valid, kubelogin does nothing.
-
-```console
-% kubelogin
-You already have a valid token until 2019-05-18 10:28:51 +0900 JST
-```
-
-If the ID token has expired, kubelogin will refresh the token using the refresh token in the kubeconfig.
-If the refresh token has expired, kubelogin will proceed the authentication.
-
-## Usage
-
-You can set path to the kubeconfig file by the option or the environment variable just like kubectl.
-It defaults to `~/.kube/config`.
-
-```sh
-# by the option
-kubelogin --kubeconfig /path/to/kubeconfig
-
-# by the environment variable
-KUBECONFIG="/path/to/kubeconfig1:/path/to/kubeconfig2" kubelogin
-```
-
-If you set multiple files, kubelogin will find the file which has the current authentication (i.e. `user` and `auth-provider`) and write a token to it.
-
-Kubelogin supports the following keys of `auth-provider` in a kubeconfig.
-See [kubectl authentication](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#using-kubectl) for more.

-```
-
-## 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
-```
-
-### PKCE
-
-Kubelogin automatically uses the PKCE if the provider supports it.
-It determines the code challenge method by the `code_challenge_methods_supported` claim of the OpenID Connect Discovery document.
-
-If your provider does not return a valid `code_challenge_methods_supported` claim,
-you can enforce the code challenge method by `--oidc-pkce-method`.
-
-```yaml
- --oidc-pkce-method=S256
-```
-
-For the most providers, you don't need to set this option explicitly.
-
-### HTTP headers
-
-If your provider requires extra HTTP headers, you can set them by `--oidc-request-header`.
-
-For Azure AD Single Page Application with PKCE, you can set `Origin` header as follows:
-
-```yaml
- --oidc-request-header=Origin=localhost
-```
-
-### 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).
-
-### Token cache
-
-Kubelogin stores the token cache to the file system by default.
-
-You can store the token cache to the OS keyring for enhanced security.
-It depends on [zalando/go-keyring](https://github.com/zalando/go-keyring).
-
-```yaml
- --token-cache-storage=keyring
-```
-
-You can delete the token cache by the clean command.
-
-```console
-% kubectl oidc-login clean
-Deleted the token cache at /home/user/.kube/cache/oidc-login
-Deleted the token cache from the keyring
-```
-
-For systems with immutable storage and no keyring, a cache type of none is available.
-
-### 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:
-
- [Device Authorization Grant](#device-authorization-grant)
- [Authorization Code Flow](#authorization-code-flow)
- [Authorization Code Flow with a Keyboard](#authorization-code-flow-with-a-keyboard)
- [Resource Owner Password Credentials Grant](#resource-owner-password-credentials-grant)
- [Client Credentials Flow](#client-credentials-flow)
-
-### Device Authorization Grant
-
-It performs the [Device Authorization Grant (RFC 8628)](https://tools.ietf.org/html/rfc8628) when `--grant-type=device-code` is set.
-
-```yaml
- --grant-type=device-code
-```
-
-It automatically opens the browser.
-If the provider returns the `verification_uri_complete` parameter, you don't need to enter the code.
-Otherwise, you need to enter the code shown.
-
-If you encounter a problem with the browser, you can change the browser command or skip opening the browser.
-
-```yaml
-# Change the browser command
- --browser-command=google-chrome
-# Do not open the browser
- --skip-open-browser
-```
-
-### Authorization Code Flow
-
-It performs the [Authorization Code Flow](https://openid.net/specs/openid-connect-core-1_0.html#CodeFlowAuth) when `--grant-type=authcode` is set or the flag is not given.
-
-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
-```
-
-The redirect URL defaults to `http://localhost` with the listening port.
-You can override the redirect URL.
-
-```yaml
- --oidc-redirect-url=http://127.0.0.1:8000/
- --oidc-redirect-url=http://your-local-hostname:8000/
-```
-
-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 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
-```
-
-If you encounter a problem with the browser, you can change the browser command or skip opening the browser.
-
-```yaml
-# Change the browser command
- --browser-command=google-chrome
-# Do not open the browser
- --skip-open-browser
-```
-
-### 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
-```
-
-You need to explicitly set the redirect URL.
-
-```yaml
- --oidc-redirect-url=urn:ietf:wg:oauth:2.0:oob
- --oidc-redirect-url=http://localhost
-```
-
-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
-```
-
-You can add extra parameters to the authentication request.
-
-```yaml
- --oidc-auth-request-extra-params=ttl=86400
-```
-
-### Resource Owner Password Credentials Grant
-
-It performs the [Resource Owner Password Credentials Grant](https://datatracker.ietf.org/doc/html/rfc6749#section-4.3)
-when `--grant-type=password` or `--username` is set.
-
-Note that most OIDC providers do not support this grant.
-Keycloak supports this grant 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:
-```
-
-### Client Credentials Flow
-
-It performs the [OAuth 2.0 Client Credentials Flow](https://datatracker.ietf.org/doc/html/rfc6749#section-1.3.4) when `--grant-type=client-credentials` is set.
-
-```yaml
- --grant-type=client-credentials
-```
-
-Per specification, this flow only returns authorization tokens.
-
-## 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/v1
-        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.
