K8S中Jenkins该怎么安装-创新互联
今天就跟大家聊聊有关K8S中Jenkins该怎么安装，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。
一、Jenkins安装准备条件
#在运维主机操作： 1.准备镜像 ~]# docker pull jenkins/jenkins:2.190.3 ~]# docker images | grep jenkins ~]# docker tag 22b8b9a84dbe test-harbor.cedarhd.com/public/jenkins:v2.190.3 ~]# docker push test-harbor.cedarhd.com/public/jenkins:v2.190.3 2.自定义Dockerfile #官网拉取的镜像需要做些自定义操作，才能在k8s集群中部署(运维主机上运行) mkdir -p /data/dockerfile/jenkins cd /data/dockerfile/jenkins vim Dockerfile FROM test-harbor.cedarhd.com/public/jenkins:v2.190.3 USER root RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime &&\ echo 'Asia/Shanghai' >/etc/timezone ADD id_rsa /root/.ssh/id_rsa ADD config.json /root/.docker/config.json ADD get-docker.sh /get-docker.sh RUN echo "StrictHostKeyChecking no" >> /etc/ssh/ssh_config &&\ /get-docker.sh #解释： > - 设置容器用户为root > - 设置容器内的时区 > - 将ssh私钥加入（使用git拉代码时要用到，配对的公钥应配置在gitlab中） > - 加入了登录自建harbor仓库的config文件 > - 修改了ssh客户端的 > - 安装一个docker的客户端 > - 如果因为网络原因构建失败，可以在最后“ /get-docker.sh --mirror Aliyun” 3.生成ssh密钥对 jenkins]# ssh-keygen -t rsa -b 2048 -C "xxxxxxx@qq.com" -N "" -f /root/.ssh/id_rsa Generating public/private rsa key pair. Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: SHA256:bIajghsF/BqJouTeNvZXvQWvolAKWvhVSuZ3uVWoVXU 897307140@qq.com The key's randomart image is: +---[RSA 2048]----+ | ...E| |. o .| |.. o . o . | |..+ + oo +.. | |o=.+ +ooS+..o | |=o* o.++..o. o | |++...o .. + | |.o.= .. . o | |..o.o.... . | +----[SHA256]-----+ enkins]# cp /root/.ssh/id_rsa . 4.准备其它文件 jenkins]# cp /root/.docker/config.json . jenkins]# curl -fsSL get.docker.com -o get-docker.sh jenkins]# chmod +x get-docker.sh jenkins]# ll total 28 -rw------- 1 root root 160 Jan 28 23:41 config.json -rw-r--r-- 1 root root 355 Jan 28 23:38 Dockerfile -rwxr-xr-x 1 root root 13216 Jan 28 23:42 get-docker.sh -rw------- 1 root root 1675 Jan 28 23:38 id_rsa 5、登陆harbor创建infra私有仓库 创建infra的project，access level 为Private 6、生成jenkins镜像 jenkins]# docker build -t harbor.phc-dow.com/infra/jenkins:v2.190.3 . jenkins]# docker push test-harbor.cedarhd.com/infra/jenkins:v2.190.3 7、准备共享存储 yum install nfs-utils -y ~]# vim /etc/exports /data/nfs-volume 10.4.7.0/24(rw,no_root_squash) ###启动NFS服务 ~]# mkdir -p /data/nfs-volume ~]# systemctl start nfs ~]# systemctl enable nfs
二、Jenkins安装所需资源配置清单
mkdir /data/k8s-yaml/jenkins && mkdir -p /data/nfs-volume/jenkins_home && cd /data/k8s-yaml/jenkins ~]# vi dp.yaml #用于创建配置pod控制器与pod资源 kind: Deployment apiVersion: extensions/v1beta1 metadata: name: jenkins namespace: infra labels: name: jenkins spec: replicas: 1 selector: matchLabels: name: jenkins template: metadata: labels: app: jenkins name: jenkins spec: volumes: - name: data nfs: server: test-operator.cedarhd.com path: /data/nfs-volume/jenkins_home - name: docker hostPath: path: /run/docker.sock type: '' containers: - name: jenkins image: test-harbor.cedarhd.com/infra/jenkins:v2.190.3 imagePullPolicy: IfNotPresent ports: - containerPort: 8080 protocol: TCP env: - name: JAVA_OPTS value: -Xmx512m -Xms512m volumeMounts: - name: data mountPath: /var/jenkins_home - name: docker mountPath: /run/docker.sock imagePullSecrets: - name: harbor securityContext: runAsUser: 0 strategy: type: RollingUpdate rollingUpdate: maxUnavailable: 1 maxSurge: 1 revisionHistoryLimit: 7 progressDeadlineSeconds: 600 ----------------------------------------------------------------------------------------------- ~]# vim service.yaml #用于创建cluster ip与端口映射 kind: Service apiVersion: v1 metadata: name: jenkins namespace: infra spec: ports: - protocol: TCP port: 80 targetPort: 8080 selector: app: jenkins jenkins]# cat ingress.yaml #用于创建ingress转发规则 kind: Ingress apiVersion: extensions/v1beta1 metadata: name: jenkins namespace: infra spec: rules: - host: test-jenkins.cedarhd.com http: paths: - path: / backend: serviceName: jenkins servicePort: 80 -----------------------------------------------------------------------------------------------
三、在其中一个运算节点上创建资源
kubectl apply -f http://k8s-yaml.cedarhd.com/jenkins/dp.yaml kubectl apply -f http://k8s-yaml.cedarhd.com/jenkins/service.yaml kubectl apply -f http://k8s-yaml.cedarhd.com/jenkins/ingress.yaml
