Jenkins远程管理K8S集群实现自动POD部署

大致思路

  1. 修改.kube/config 文件，增加新集群的context
  2. 建立隧道将集群控制端口映射到Jenkins服务器本地端口
  3. 测试jenkin 切换到新context 是否能控制该集群
  4. 新集群配置对接Harbor仓库
  5. 测试helm部署pod
  6. Jenkins测试配置流水线自动发版

1. 配置Jenkins与集群网络代理

网络代理脚本

#!/usr/bin/env bash
  
set -o xtrace

export AUTOSSH_LOGFILE="/root/autossh.log"
# 这个变量会被k8s自动设置，跟autossh本身的有冲突，这里取消k8s设置的
unset AUTOSSH_PORT

# ======= autossh options =========
# -M specifies the base monitoring port to use, this port and the port
#    immediately above it ( port + 1) should be something nothing else is using
# -f causes autossh to drop to the background before running ssh
# ======= ssh options ========
# -N Do not execute a remote command.  This is useful for just forwarding ports.
# -R 0.0.0.0:30080:192.168.118.180:30080 ztmoon 把远程服务器ztmoon上的30080端口指向本地局域网内192.168.118.180上的30080端口
autossh -M 10001 -f -N \
  -R 0.0.0.0:35443:127.0.0.1:6443 \
  -R 0.0.0.0:35222:127.0.0.1:22 \
  -R 0.0.0.0:35357:127.0.0.1:30357 \

set +o xtrace

查看Jenkins主机端口情况

[root@app-04 .ssh]# netstat -lntup | grep 35
tcp        0      0 0.0.0.0:35443           0.0.0.0:*               LISTEN      32546/sshd: zxx
tcp        0      0 0.0.0.0:35222           0.0.0.0:*               LISTEN      32546/sshd: zxx
tcp        0      0 0.0.0.0:35357           0.0.0.0:*               LISTEN      32546/sshd: zxx

2. 配置Jenkins远程管理集群

2.1 Jenkins-config文件中增加新集群信息

在kubeconfig中，context中将访问一个集群的参数进行分组。访问这个context名称就是访问这个参数组。context就是一组信息的别名，举例来说，当在高德中使用家的地址，公司的地址就是一个别名，就能迅速的定位到具体的地址信息。

kubeconfig中主要由如下部分组成：

  • clusters （集群）

  • users（用户）

  • context（上下文）

默认情况下，kubectl命令从current context中来获取参数，然后与集群进行通讯。

- cluster：

3. 初始化项目集群

3.1创建项目namespace和SA账号

# namespace
---
apiVersion: v1
kind: Namespace
metadata:
  name: jtcs-prod
  labels:
    name: jtcs-prod


# Default Memory Requests and Limits
---
apiVersion: v1
kind: LimitRange
metadata:
  name: mem-limit-range
  namespace: jtcs-prod
spec:
  limits:
    - default:
        memory: 4096Mi
      defaultRequest:
        memory: 128Mi
      type: Container

---
apiVersion: v1
kind: ServiceAccount
metadata:
  name: jtcs-prod
  namespace: jtcs-prod

---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: jtcs-prod-rolebinding
  namespace: jtcs-prod
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: edit
subjects:
  - kind: ServiceAccount
    name: jtcs-prod
    namespace: jtcs-prod

root@k8s-made-01-32:/yaml/namespace# kubectl apply -f jtcs.yaml

从 1.24 开始就不会自动生成 secret 了，chanagelog 在这里.

3.2 创建SA账户token

apiVersion: v1
kind: Secret
metadata:
  name: build-robot-secret
  namespace: jtcs-prod
  annotations:
    kubernetes.io/service-account.name: jtcs-prod
type: kubernetes.io/service-account-token

控制面会自动为该 ServiceAccount 生成一个令牌，并将其保存到相关的 Secret 中

root@k8s-made-01-32:/script# kubectl describe -n jtcs-prod secrets/build-robot-secret
Name:         build-robot-secret
Namespace:    jtcs-prod
Labels:       <none>
Annotations:  kubernetes.io/service-account.name: jtcs-prod
              kubernetes.io/service-account.uid: 95be2e94-1cfe-40ae-b181-a11fe82e1314

Type:  kubernetes.io/service-account-token

手动为 ServiceAccount 创建 API 令牌

3.3 创建管理员账号

# 1, kubectl apply -f jn-admin.serviceAccount.yaml
# 3, kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep jn-admin | awk '{print $1}')

---

apiVersion: v1
kind: ServiceAccount
metadata:
  name: jtcs-admin
  namespace: kube-system

---

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: jtcs-admin
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin

    name: jtcs-admin
    namespace: kube-system

3.4 测试Jenkins远程管理集群

4.Jenkins远程部署业务

4.1 创建Harbor secret

4.1.1 脚本中定义变量信息

imageName="${REGISTRY}/${NAMESPACE}/${PROJECT_NAME}:${ImageTag}"

REGISTRY="harbor.rmxc.tech"

4.2 部署mysql 57
