部署 prometheus-adapter 的 custom-metrics-api 失败

Question

根据 custom-metrics-api 的 readme ，运行 ./deploy.sh 命令部署 custom-metrics-api 却失败。

kubectl get apiservices -n monitoring | grep metrics 输出如下：

v1beta1.custom.metrics.k8s.io          monitoring/prometheus-adapter   False (FailedDiscoveryCheck)   93s

kubectl describe apiservices v1beta1.custom.metrics.k8s.io -n monitoring 输出的错误信息如下：

failing or missing response from https://10.96.132.172:443/apis/custom.metrics.k8s.io/v1beta1: bad status from https://10.96.132.172:443/apis/custom.metrics.k8s.io/v1beta1: 404

kubectl get ev -n monitoring 发现下面的错误信息：

MountVolume.SetUp failed for volume "config" : configmap "adapter-config" not found

请问如何解决？

需要部署 k8s-prometheus-adapter ，详见 k8s 安装 prometheus 过程记录
