I'm trying to upgrade Prometheus Blackbox Exporter to v0.24.0 using Helm chart v8.10.1 on my AWS EKS Kubernetes cluster v1.25 but it is failing with the following error:
helm upgrade -n monitoring prometheus-blackbox-exporter prometheus-community/prometheus-blackbox-exporter --version 8.10.1
Error: UPGRADE FAILED: unable to build kubernetes objects from current release manifest: resource mapping not found for name: "prometheus-blackbox-exporter" namespace: "monitoring" from "": no matches for kind "PodSecurityPolicy" in version "policy/v1beta1"
How to solve this?
First, you need install helm-mapkubeapis (one time action per AWS EKS Kubernetes cluster). Then you need to run helm mapkubeapis for the prometheus-blackbox-exporter Helm release and then you need to delete the prometheus-blackbox-exporter Helm release and then you need to install it again.
Below you can see all the commands for the above mentioned steps:
helm plugin install https://github.com/helm/helm-mapkubeapis
helm mapkubeapis -n monitoring prometheus-blackbox-exporter
helm del -n monitoring prometheus-blackbox-exporter
helm install -n monitoring prometheus-blackbox-exporter prometheus-community/prometheus-blackbox-exporter --version 8.10.1
Note: It is assumed that the Prometheus Helm charts repository is already added to your AWS EKS Kubernetes cluster. If not, you can run the following command to do so: helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
