This helm chart installs Ark version v0.9.0 https://github.com/heptio/ark/tree/v0.9.0

Prerequisites

Secret for cloud provider credentials

Ark server needs an IAM service account in order to run, if you don't have it you must create it. Please follow the official documentation: https://heptio.github.io/ark/v0.9.0/cloud-common

kubectl create secret generic cloud-credentials --namespace <ARK_NAMESPACE> --from-file cloud=credentials-ark
