The charts in this folder install dex
with dex-k8s-authenticator
dex-k8s-authenticator is a helper application for dex. dex lets you use external
Identify Providers (like Google, Microsoft, GitHub, LDAP) to authenticate access to Kubernetes cluster
(e.g. for kubectl). This helper makes it easy to provide a web UI for one or more clusters.
It gives users the information and commands to configure kubectl to work with the credentials dex provides.
Each install of dex and/or dex-k8s-authenticator can support multiple Kubernetes clusters.
So you can install one of each for all your clusters, one in each cluster, or any combination.
git clone https://github.com/mintel/dex-k8s-authenticator.git
helm inspect values charts/dex > dex.yaml
helm inspect values charts/dex-k8s-authenticator > dex-k8s-authenticator.yaml
Edit the values files for your environment and requirements (dex.yaml and dex-k8s-authenticator.yaml).
Create the DNS names for your dex (e.g. 'dex.example.com') and dex-k8s-authenticator (e.g. 'login.example.com')
pointed at the ingress controller you are using. Be sure to enable HTTPS. You can install
cert-manager to automatically issue Lets Encrypt certificates.
You also need to configure each Kubernetes cluster to use dex at e.g. 'dex.example.com' by setting the OIDC parameters
for the Kubernetes API server.
This is easy using kube-aws installer.
helm install --namespace dex --values dex.yaml charts/dex
helm install --namespace dex --values dex-k8s-authenticator charts/dex-k8s-authenticator
Navigate to https://login.example.com and follow the instructions to authenticate using dex and configure kubectl.
