Improve Reloader controller logs

[SachithKasthuriarachchi]

In my AKS cluster with kubernetes version v1.25.6 the reloader seems to be stuck in the starting controller state.

time="2023-07-31T15:18:54Z" level=info msg="Environment: Kubernetes"
time="2023-07-31T15:18:54Z" level=info msg="Starting Reloader"
time="2023-07-31T15:18:54Z" level=warning msg="KUBERNETES_NAMESPACE is unset, will detect changes in all namespaces."
time="2023-07-31T15:18:54Z" level=info msg="created controller for: configMaps"
time="2023-07-31T15:18:54Z" level=info msg="Starting Controller to watch resource type: configMaps"
time="2023-07-31T15:18:54Z" level=info msg="created controller for: secrets"
time="2023-07-31T15:18:54Z" level=info msg="Starting Controller to watch resource type: secrets"

However, the version v0.0.58 works fine

it seems reloader does not work at all in kubernetes v1.24.9

[SachithKasthuriarachchi]

@stakater-user do you have an idea about this? the latest 1.0.34 also does not work

[SachithKasthuriarachchi]

Apologies for this issue. The reloader works fine. I was confused since the log was stopped at the above.

time="2023-07-31T15:18:54Z" level=info msg="Starting Controller to watch resource type: secrets"

Can we improve this log message to say that the controller is started and it is watching the resources?

@SachithKasthuriarachchi We try to follow standard logging that is generally used across k8s products. But feel free to raise a PR to add another log line after the one we already have:

time="2023-07-31T15:18:54Z" level=info msg="Starting Controller to watch resource type: secrets"
time="2023-07-31T15:18:54Z" level=info msg="Started Controller to watch resource type: secrets"
