手动部署prometheus

docker方式部署

1. 先搭建k8s环境

https://blog.csdn.net/weixin_45842014/article/details/108757132

2. 创建kube-ops命名空间(master)

cd /usr/local/src

mkdir prometheus

cd prometheus

vim prom-ns.yaml -----编辑文件

apiVersion: v1
kind: Namespace
metadata:
  name: kube-ops
  labels:
    name: kube-ops

kubectl create -f prom-ns.yaml -----创建kube-ops命名空间

[root@k8s-master src]# kubectl get ns -A
NAME              STATUS   AGE
kube-ops          Active   12s

cd /usr/local/src

mkdir prometheus

cd prometheus

vim prom-sa.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: prometheus
  namespace: kube-ops

[root@k8s-master prometheus]# kubectl get sa -A|grep prometheus
kube-ops               prometheus                           1         4h46m

yum -y install rpcbind nfs-utils
systemctl start rpcbind
systemctl start nfs
vim /etc/exports

mkdir /data/k8s
cd
ls
ll /data
mkdir -p /data/k8s
showmount -e

 cd prometheus/
