Dex

Dex is an identity service that uses OpenID Connect to drive authentication for other apps.

You can use Dex for example to provide OIDC authentication using users from an LDAP backend.

ℹ️ Learn more about Dex in the official documentation.

Requirements

• Kubernetes >= 1.24.0
• Kustomize >= v3

Image repository and tag

• Dex repository: https://github.com/dexidp/dex
• Dex container image: registry.sighup.io/fury/dexidp/dex:v2.41.1

Configuration

Dex is deployed with the following default configuration:

• Replica number: 1
• Listens on port 5556
• Resource limits are 250m for CPU and 200Mi for memory

Dex is configured using a config.yml file. You can get a sample file from the official docs or check out the provided LDAP-based example configuration file

Once you have written the configuration file for your environment, create a Kubernetes secret named dex in the kube-system namespace with the contents of the file under the config.yml key.

ℹ️ We recommend you do this using Kustomize, either with a secretGenerator or as a resource.

The dex secret will then be mounted by the deployment as a volume in the right path.

Deployment

Once you have created the configuration file, you can deploy Dex by running the following command in the folder of this package:

kustomize build | kubectl apply -f -
