The issue was with type of upgrade strategy, which was rendered as empty.
It was due to wrong access to the pod_replacement_strategy, which was
out of modified scope:
daemonsets:
pod_replacement_strategy: RollingUpdate
dhcp_agent:
enabled: false
min_ready_seconds: 0
max_unavailable: 1
and the snippet was modifying the scope to daemonset.dhcp_agent, then
trying to access daemonsets.dhcpagent.pod_replacement_strategy, which was
not there:
{{- $upgradeMap := index $envAll.Values.pod.lifecycle.upgrades.daemonsets $component }}
updateStrategy:
type: {{ .pod_replacement_strategy }}
The fix is to evaluate the common variable before entering the scope
modification.
{{- $pod_replacement_strategy := $envAll.Values.pod.lifecycle.upgrades.daemonsets.pod_replacement_strategy -}}
type: {{ $pod_replacement_strategy }}
