Version support

Note

: This Chart is still in development and still subject to change the API (values.yaml). Until we reach a 1.0.0 version of the chart we can't guarantee backwards compatibility although we do aim for as much stability as possible.

Dependency	Supported Versions
SPIRE	1.5.3+, 1.6.3+
Helm	3.x
Kubernetes	1.22+

Note

: For Kubernetes, we will officially support the last 3 versions as described in k8s versioning. Any version before the last 3 we will try to support as long it doesn't bring security issues or any big maintenance burden.

Usage

To utilize Spire in your own workloads you should add the following to your workload:

 apiVersion: v1
 kind: Pod
 metadata:
   name: my-app
 spec:
   containers:
     - name: my-app
       image: "my-app:latest"
       imagePullPolicy: Always
+      volumeMounts:
+        - name: spiffe-workload-api
+          mountPath: /spiffe-workload-api
+          readOnly: true
       resources:
         requests:
           cpu: 200m
           memory: 32Mi
         limits:
           cpu: 500m
           memory: 64Mi
+  volumes:
+    - name: spiffe-workload-api
+      csi:
+        driver: "csi.spiffe.io"
+        readOnly: true

Now you can interact with the Spire agent socket from your own application. The socket is mounted on /spiffe-workload-api/spire-agent.sock.

Install notes

To do a quick non production install:

kubectl create namespace spire-system
helm install -n spire-system spire-crds charts/spire-crds
helm install -n spire-system spire charts/spire

For production installs, please see [the production example](examples/production/).

## Upgrade notes

0.14.X:

If coming from a chart version before 0.14.0, you must relabel your crds to switch to using the new spire-crds chart. To migrate to the spire-crds chart
run the following:

```shell
# Replace the spire-server namespace in the commands below with the namespace you want to install the spire-crds chart in.

kubectl label crd "clusterfederatedtrustdomains.spire.spiffe.io" "app.kubernetes.io/managed-by=Helm"
kubectl annotate crd "clusterfederatedtrustdomains.spire.spiffe.io" "meta.helm.sh/release-name=spire-crds"
kubectl annotate crd "clusterfederatedtrustdomains.spire.spiffe.io" "meta.helm.sh/release-namespace=spire-server"
kubectl label crd "clusterspiffeids.spire.spiffe.io" "app.kubernetes.io/managed-by=Helm"
kubectl annotate crd "clusterspiffeids.spire.spiffe.io" "meta.helm.sh/release-name=spire-crds"
kubectl annotate crd "clusterspiffeids.spire.spiffe.io" "meta.helm.sh/release-namespace=spire-server"
kubectl label crd "controllermanagerconfigs.spire.spiffe.io" "app.kubernetes.io/managed-by=Helm"
kubectl annotate crd "controllermanagerconfigs.spire.spiffe.io" "meta.helm.sh/release-name=spire-crds"
kubectl annotate crd "controllermanagerconfigs.spire.spiffe.io" "meta.helm.sh/release-namespace=spire-server"
helm install -n spire-server spire-crds charts/spire-crds
