Filebeat: failed validation with Helm 2.14 / kubernet 1.14

[dperetti]

Chart version:
7.0.1-alpha1

Kubernetes version:
1.14.1

Kubernetes provider: E.g. GKE (Google Kubernetes Engine)
DigitalOcean

Helm Version:
2.14.0

Helm rejects the install with:

Error: validation failed: error validating "": error validating data: 
ValidationError(DaemonSet.spec.template.spec.containers[0].securityContext):
unknown field "fsGroup" in io.k8s.api.core.v1.SecurityContext

My understanding is that the podSecurityContext should be only set in spec.securityContext, not in spec.containers[].securityContext like it is here:
https://github.com/elastic/helm-charts/blob/master/filebeat/templates/daemonset.yaml#L108

Thanks for reporting this! I have removed it in #140. As this container needs to run as root I can't think of any valid reason to make this configurable.

That extra validation looks really nice! I'm guessing it is a 1.14 feature. Previous versions of Kubernetes will just silently ignore any fields that it doesn't know 👍 .
