Recommended production setup

To install Spire with the least privileges possible we deploy spire across 2 namespaces.

kubectl create namespace "spire-system"
kubectl label namespace "spire-system" pod-security.kubernetes.io/enforce=privileged
kubectl create namespace "spire-server"
kubectl label namespace "spire-server" pod-security.kubernetes.io/enforce=restricted

Update the example-your-values.yaml file with your values, then:

helm upgrade --install --namespace spire-server spire ../../charts/spire \
  -f values.yaml -f example-your-values.yaml --render-subchart-notes

If your using ingress-nginx and want to expose the spiffe oidc discovery provider outside the cluster, add the following to the end of the helm upgrade example:

-f values-export-spiffe-oidc-discovery-provider-ingress-nginx.yaml

If you want to expose your spire-server outside of Kubernetes and are using ingress-nginx, add following values file when running helm template/install/upgrade.

-f values-expose-spire-server-ingress-nginx.yaml

For example:

helm upgrade --install --namespace spire-server spire charts/spire -f values.yaml -f values-expose-spire-server-ingress-nginx.yaml

If you want to expose your federation endpoint outside of Kubernetes and are using ingress-nginx you have two options as described here: github.com/spiffe/spiffe/blob/main/standards/SPIFFE_Federation.md#52-endpoint-profiles

If you chose profile https_web, use:

-f values-expose-federation-https-web-ingress-nginx.yaml

For example:

helm upgrade --install --namespace spire-server spire charts/spire -f values.yaml -f values-expose-federation-https-web-ingress-nginx.yaml

If you chose profile https_spiffe, use:

-f values-expose-federation-https-spiffe-ingress-nginx.yaml

For example:

helm upgrade --install --namespace spire-server spire charts/spire -f values.yaml -f values-expose-federation-https-spiffe-ingress-nginx.yaml

See values.yaml for more details on the chart configurations to achieve this setup.
