Is there an existing issue for this?

• I have searched the existing issues

Version

equal or higher than v1.19.0 and lower than v1.20.0

What happened?

1. helm install cilium cilium/cilium --version 1.19.0
2. cilium operator crash

How can we reproduce the issue?

$ helm template cilium cilium/cilium --version 1.19.0 --set operator.unmanagedPodWatcher.intervalSeconds=15 | grep unmanaged-pod-watcher-interval
  unmanaged-pod-watcher-interval: "15"

This will cause cilium operator crash because "15" is not a valid time.Duration, it should be "15s"

Anything else?

This bug occurs because you're assuming Helm will always parse integers in values.yaml as float64. In reality, they could also be interpreted as int64 or json.Number depending on the context and helm version.

In certain Helm versions, this is even easier to reproduce.

$ helm template cilium cilium/cilium --version 1.19.0  | grep unmanaged-pod-watcher-interval
  unmanaged-pod-watcher-interval: "15"

In some other versions, it works as expected.

$ helm template cilium cilium/cilium --version 1.19.0  | grep unmanaged-pod-watcher-interval
  unmanaged-pod-watcher-interval: "15s"
