Usage

Prerequisites

Tool	Version	Description
furyctl	`>=0.6.0`	The recommended tool to download and manage KFD modules and their packages. To learn more about `furyctl` read the official documentation.
kustomize	`>=3.5.0`	Packages are customized using `kustomize`. To learn how to create your customization layer with `kustomize`, please refer to the repository.

Deployment

List the packages you want to deploy and their version in a Furyfile.yml:

versions:
    auth: "v0.2.0"
bases:
  - name: auth/pomerium
  - name: auth/dex
  - name: auth/gangplank

See furyctl documentation for additional details about Furyfile.yml format.

Execute furyctl vendor -H to download the packages
Inspect the download packages under ./vendor/katalog/auth/.
Define a kustomization.yaml that includes the ./vendor/katalog/auth directory as a resource.

resources:
  - ./vendor/katalog/auth/pomerium
  - ./vendor/katalog/auth/dex
  - ./vendor/katalog/auth/gangplank

Create the configuration file for Dex (here's an LDAP-based example) and add it as a secret to the kustomization.yaml file, like this:

secretGenerator:
  - name: dex
    namespace: kube-system
    files:
      - config.yml=./secrets/dex/config.yml

ℹ️ read more on Dex's readme.

⛔️ Before proceeding, follow the instructions in Pomerium's package readme and Gangplank's readme to configure them.

Finally, to deploy the module to your cluster, execute:

kustomize build . | kubectl apply -f -

Monitoring

KFD Auth module integrates out-of-the-box with KFD's Monitoring module. Providing metrics and dashboards to visualize the status of its components.

In particular:

Dex exposes standard Go adapter metrics, the metrics are automatically scrapped by Prometheus when using KFD Monitoring module but there are no Grafana dashboards nor alerts defined.
Pomerium exposes several metrics about Pomerium itself and its underlying envoy proxy. Metrics are scrapped automatically by Prometheus and 2 Grafana dashboards are available with the pomerium tag when using KFD Monitoring module. Here are some screenshots:
