Running helm install in sandbox-project-namespace on OPenShift 3.11

Error: unable to build kubernetes objects from release manifest: error validating “”: error validating data: [ValidationError(MutatingWebhookConfiguration.webhooks[0]): unknown field “admissionReviewVersions” in io.k8s.api.admissionregistration.v1beta1.Webhook, ValidationError(MutatingWebhookConfiguration.webhooks[0]): unknown field “sideEffects” in io.k8s.api.admissionregistration.v1beta1.Webhook]

Running across this error when trying to just run the helm install vault hashicorp/vault from my local console. Ive logged into my cluster and I’m currently in the write project. My helm version is 3.5. I’m new to trying to get Vault set up in Openshift 3.11 and cant seem to find any documentation geared towards integrating vault 1.6.0 into Openshift 3.x. Seems as most of the hashicorp docs is based more on 4.x. I can get the 1.6.0 vault deployed but I’m almost certain I have necessary components that aren’t getting deployed.

Could use some help here with a proper path to follow.

Thanks in advance.

Openshift 4.X is a requirement, so it won’t work in versions below.

There’s no current vault version that plays well with Openshift 3.11?

Hi there!
I’m zero at k8s, helm, vault, and all that things. Now I have the same error while installing the vault to the Kubernetes v1.10.13 and never thought it could be the reason without your answer. Is it compatible? Where can we find the system requirements for different vault versions?
