K8S环境部署Prometheus

K8S环境部署Prometheus

记录在K8S 1.18版本环境下部署Prometheus 0.5版本。

1. 下载kube-prometheus仓库

git clone https://github.com/coreos/kube-prometheus.git
cd kube-prometheus

笔者安装的K8S版本是1.18 ，prometheus选择配套的分支release-0.5：

# 切换到release-0.5
git checkout remotes/origin/release-0.5 -b 0.5

K8S和Pormetheus的配套关系：

kube-prometheus stack	Kubernetes 1.14	Kubernetes 1.15	Kubernetes 1.16	Kubernetes 1.17	Kubernetes 1.18
release-0.3	✔	✔	✔	✔	✗
release-0.4	✗	✗	✔	✔	✗
release-0.5	✗	✗	✗	✗	✔
HEAD	✗	✗	✗	✗	✔

最新的版本配套关系查看kube-prometheus官方仓库：https://github.com/prometheus-operator/kube-prometheus ，可以切换版本查看配套关系。

2. 查看manifest
