에러해결 MountVolume.SetUp failed for volume "tls-assets" : secret "prometheus-kube-prometheus-stack-prometheus-tls-assets" not found

비슷한 에러로 

  MountVolume.SetUp failed for volume "tls-assets" : secret "alertmanager-kube-prometheus-stack-alertmanager-tls-assets" not found

가 있다

계속 pod가 다음과 같은 이유로 terminating 될 것이다.

 

해결방법

prometheusOperator:
  tls:
    enabled: false
  admissionWebhooks:
    enabled: false

이렇게 values.yaml파일을 변경하면 

helm-charts/charts/kube-prometheus-stack/templates/prometheus-operator/deployment.yaml

 

의 값이 변경되고 에러가 사라진다

 

위의 해결방법으로 안될때

helm 차트를 uninstall하고 재설치하면 된다

helm uninstall kube-prometheus-stack -n monitoring

 

차트만 uninstall하면 안되고 crd들을 지워야 완벽히 삭제된다
