Envoyproxy image definition helm

I am attempting to run the official vault helm chart in a private cluster. The pods fail to run due to - Back-off pulling image “envoyproxy/envoy-alpine:v1.13.0” error. Where exactly, if anywhere can I configure this image to be taken from a private repository.

Thanks

You could run the Helm Chart in template mode and then manually modify as I cannot see an option to override at https://www.vaultproject.io/docs/platform/k8s/helm/configuration or update your cluster to use a private registry
