To allow for inplace upgrades of spire-server statefulset we are not allowed to make changes to all fields of the statefulset spec. When bumping from 0.8.1 to the latest version the `initContainers:` field is added in the spec and therefore does not allow for updating the statefulset. This fix prevents the empty initContainers block when bumping from a previous chart version. Signed-off-by: Marco Franssen <[email protected]> Co-authored-by: Faisal Memon <[email protected]>
