I have verified templates code for elasticsearch in<br>
openstack-helm-infra and relevant helm-toolkit code, and didn't find<br>
any visible problems. Deployments in Kubernetes v1.18 do support<br>
"strategy: ...".<br>
Could you try to render locally with "helm template ..." command and<br>
check the resulting deployments?<br>
<br>
Best regards,<br>
