k8s-1.25.0手撕yml方式部署最新版 Jenkins 2.346.3

k8s-1.25.0部署最新版 Jenkins 2.346.3

k8s版本：k8s-1.25.0（containerd运行时）

jenkins版本：Jenkins 2.346.3

1、先部署动态存储 local-path-provisioner

2、再部署 jenkins

Jenkins镜像

jenkins/jenkins:lts-jdk11

动态存储：Local Path Provisioner

基于HostPath使用动态PV

1、部署 local-path-provisioner

# 版本：local-path-provisioner-0.0.22
wget https://github.com/rancher/local-path-provisioner/archive/refs/tags/v0.0.22.tar.gz
# github.com下载加速地址
wget https://hub.fastgit.xyz/rancher/local-path-provisioner/archive/refs/tags/v0.0.22.tar.gz
tar xf v0.0.22.tar.gz && rm -rf v0.0.22.tar.gz
# 修改存储地址（/data/local-path-provisioner）
sed -i 's/opt/data/g' ~/local-path-provisioner-0.0.22/deploy/local-path-storage.yaml

kubectl apply -f ~/local-path-provisioner-0.0.22/deploy/local-path-storage.yaml
kubectl get pod -A -l app=local-path-provisioner
kubectl get pod -n local-path-storage
kubectl get storageclass

2、部署 Jenkins
