Nginx openid connect

Edit This Page. All Kubernetes clusters have two categories of users: service accounts managed by Kubernetes, and normal users. Normal users are assumed to be managed by an outside, independent service. An admin distributing private keys, a user store like Keystone or Google Accounts, even a file with a list of usernames and passwords. In this regard, Kubernetes does not have objects which represent normal user accounts.

Normal users cannot be added to a cluster through an API call. In contrast, service accounts are users managed by the Kubernetes API.

Configure Applications with OpenID Connect Discovery

Service accounts are tied to a set of credentials stored as Secretswhich are mounted into pods allowing in-cluster processes to talk to the Kubernetes API. API requests are tied to either a normal user or a service account, or are treated as anonymous requests.

This means every process inside or outside the cluster, from a human user typing kubectl on a workstation, to kubelets on nodes, to members of the control plane, must authenticate when making requests to the API server, or be treated as an anonymous user.

Kubernetes uses client certificates, bearer tokens, an authenticating proxy, or HTTP basic auth to authenticate API requests through authentication plugins. All values are opaque to the authentication system and only hold significance when interpreted by an authorizer.

You can enable multiple authentication methods at once. You should usually use at least two methods:. When multiple authenticator modules are enabled, the first module to successfully authenticate the request short-circuits evaluation. The API server does not guarantee the order authenticators run in.

The system:authenticated group is included in the list of groups for all authenticated users.

Integrations with other authentication protocols LDAP, SAML, Kerberos, alternate x schemes, etc can be accomplished using an authenticating proxy or the authentication webhook. The referenced file must contain one or more certificate authorities to use to validate client certificates presented to the API server.

If a client certificate is presented and verified, the common name of the subject is used as the user name for the request. As of Kubernetes 1. To include multiple group memberships for a user, include multiple organization fields in the certificate.

For example, using the openssl command line tool to generate a certificate signing request:. See Managing Certificates for how to generate a client cert. Currently, tokens last indefinitely, and the token list cannot be changed without restarting API server.

The token file is a csv file with a minimum of 3 columns: token, user name, user uid, followed by optional group names. For example: if the bearer token is 31ada4fd-adecca-9e56ceb then it would appear in an HTTP header as shown below. To allow for streamlined bootstrapping for new clusters, Kubernetes includes a dynamically-managed Bearer token type called a Bootstrap Token.Kubernetes Dashboard is a cool web UI for Kubernetes clusters. In this article, we configure the following stack:.

You can deploy a Keycloak server from the Helm chart. In this article, it assumes the followings:. Add a client with the following properties:. Then create a mapper. It allows group based access control. Now the Keycloak becomes an identity provider. As well as you can use your Google account. This is easier. If you are using kops, add the following by kops edit cluster :.

If you are using kube-aws, add the following to cluster. Now the kube-apiserver can authenticate by an ID token. Run an OpenID Connect proxy server. You can deploy a keycloak-proxy from the Helm chart as follows:. Above example uses an ingress to publish the proxy port but you can use a NodePort or LoadBalancer as well. You can configure that by the ConfigMap.

You can install a Kubernetes Dashboard from the Helm chart. Since no role is given to the current user or group, an Unauthorized warning will be shown on the dashboard. Assign the cluster-admin role to the current group. Now all objects are shown in the dashboard. Note that the cluster-admin role is a super administrator and can do everything. Consider a dedicated role in your actual operation.GitHub repository.

Signature validation ensures that the JWT was issued by Google and has not been modified since. Google publishes its public keys and refreshes them regularly. It explains how to proxy authenticated requests with user identity information obtained from the JWT, log JWT claims, and support multiple identity providers. Use these instructions as a reference and adapt them to the current GUI as necessary.

The page that opens depends on your history with Google APIs. You might have to create an account, accept terms of use, and perform other steps not shown in these instructions. Ultimately you need to access the Google APIs dashboard. The following screenshot shows the upper left corner of the dashboard. Create a new project.

After you click the Create button, it can take several seconds before a notification appears indicating your project has been created. Click the Create button you might need to click it more than once to make the creation process start.

You do not need the client secret. Provide your email address and a product name all other fields are optional. Return to the instructions for creating a sample application that uses the credentials.

This is what gives us the login button and can detect whether we are logged in or not. The line Cookies.I think there are 2, kind of, limitations that are worth mentioning: one is that it talks to a single provider only so no multi-provider setup is possible, the other is that it supports the Authorization Code grant type only.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I have a basic Nginx docker image, acting as a reverse-proxy, that currently uses basic authentication sitting in front of my application server.

Sure, there are open source codes, which you can use and customize for your case example. IMHO there are better implementations, which you can use as an "auth proxy" in front of your application. My favorite is keycloak-gatekeeper you can use it with any OpenID IdP, not only with the Keycloakwhich can provide authentication, authorization, token encryption, refresh token implementation, small footprint, When used as an OAuth 2.

So my keycloak authentication address is like:. I have setup a confidential client in keycloak with Authorization Code and the redirect url for it is:.

When my app takes a user to the Keycloak login page, I am getting:. Keycloak standalone-ha. I was able to fix this; probably not in the best way but it is working for now. I needed to also set in nginx config:. If anyone finds a way to do this without having the insecure valid redirect I would be very keen to know as I know this is not recommended.

Figure 2. OpenID Connect authorization code flow protocol. NGINX Plus then stores the ID token in the key-value store, issues a session cookie to the client using a random string, which becomes the key to obtain the ID token from the key-value store and redirects the client to the original URI requested prior to authentication.

Subsequent requests to protected resources are authenticated by exchanging the session cookie for the ID Token in the key-value store. JWT validation is performed on each request, as normal, so that the ID Token validity period is enforced. If a refresh token was received from the IdP then it is also stored in the key-value store. If the user's session is still valid at the IdP then a new ID token is received, validated, and updated in the key-value store.

The refresh process is seamless to the client.

Therefore, subsequent requests to protected resources will be treated as a first-time request and send the client to the IdP for authentication.

Note that the IdP may issue cookies such that an authenticated session still exists at the IdP. The njs module needs to be loaded by adding the following configuration directive near the top of nginx.

Switch to the correct branch to ensure compatibility with the features and syntax of each release. In this case you can skip the frontend. Review the following files copied from the GitHub repository so that they match your IdP configuration. This file can be automatically configured by using the configure.

The key-value store is used to maintain persistent storage for ID tokens and refresh tokens. The default configuration should be reviewed so that it suits the environment.

Each session will typically occupy KB, depending on the size of the JWT, so scale this value to exceed the number of unique users that may authenticate.

The NGINX Plus user account, typically nginxmust have write permission to the directory where the state file is stored. Consider creating a dedicated directory for this purpose.

This should be set to value slightly longer than the JWT validity period. JWT validation occurs on each request, and will fail when the expiry date exp claim has elapsed.

If JWTs are issued without an exp claim then set timeout to the desired session duration. If JWTs are issued with a range of validity periods then set timeout to exceed the longest period. The API can also be used to manage the current set of active sessions. Check the contents of this file as it may include error responses received by the IdP.
