Install with Helm

Add Helm repository

helm repo add opencve https://cleveritcz.github.io/opencve-helm/opencve
helm repo update

Download values.yaml, change host name in ingress section and what others you want to have

helm show values opencve/opencve > values.yaml

Install opencve with this command

helm install opencve opencve/opencve -n opencve --create-namespace -f values.yaml

Install with git

Download git repository

git clone https://github.com/cleveritcz/opencve-helm.git
cd opencve-helm

Change host in values.yaml under ingress section from opencve.cleverit.cz to your domain where the application will be running.

Check if everything is running except opencve-celery-beat

kubectl get pods -n opencve

Then run these commands:

export POD_NAME=$(kubectl get pods --namespace opencve -l "app=webserver" -o jsonpath="{.items[0].metadata.name}")
kubectl exec -it $POD_NAME -n opencve -- opencve create-user john john.doe@example.com --admin

Caveats

Please note that the initialization can take several minutes while OpenCVE downloads and imports the CVEs, CPEs and co.
Even when uninstalling the pvc will remain on the k8s cluster. If you change certain settings (like postgres passwords) you need to delete the pvc manually and let the init container reinitialize it.
Autoscaling is working from Kubernetes v1.23 and higher

Uninstallation

helm uninstall opencve -n opencve
kubectl delete pvc data-opencve-postgresql-0 -n opencve --force
kubectl delete ns opencve --force

We provide a documentation with the details of each step.
