BUG REPORT

What happened:

Tried installing on OpenShift and received an error, installation did not complete.

helm install --debug my-release --set etcdEndPoint=etcd:http://192.168.70.90:2379,clusterName=$(uuidgen) ./helm/charts/portworx/ --set openshiftInstall=true --set registrySecret=sbu-pipeline

What you expected to happen:
I expect the install to be performed.

How to reproduce it (as minimally and precisely as possible):
I did the following:

git clone https://github.com/portworx/helm.git
helm install --debug my-release --set etcdEndPoint=etcd:http://192.168.70.90:2379,clusterName=$(uuidgen) ./helm/charts/portworx/ --set openshiftInstall=true --set registrySecret=sbu-pipeline

Anything else we need to know?:
I believe this can be fixed by amending https://github.com/portworx/helm/blob/master/charts/portworx/templates/portworx-ds.yaml#L219 from:

{{- if (semverCompare ">=1.9" .Capabilities.KubeVersion.GitVersion) or (.Values.openshiftInstall and semverCompare ">=1.8" .Capabilities.KubeVersion.GitVersion) }}

to

{{- if or (semverCompare ">=1.9" .Capabilities.KubeVersion.GitVersion) (and (.Values.openshiftInstall) (semverCompare ">=1.8" .Capabilities.KubeVersion.GitVersion)) }}

I have done this in my environment and the installation was then performed successfully.
