K8S+Jenkins+Harbor+Docker+gitlab服务器集群部署

1.准备以下服务器

centos7系统：CentOS-7-x86_64-Minimal-2009.iso

所有服务器账号root 密码:123456

vmware17虚拟机

服务/结点	Ip地址	配置
k8s-master	192.168.85.141	2CPU/2核 4G内存
k8s-node1	192.168.85.142	2CPU/2核 4G内存
k8s-node2	192.168.85.143	2CPU/2核 4G内存
Jenkins	192.168.85.144	2CPU/2核 8G内存
Gitlab	192.168.85.145	2CPU/2核 8G内存
Harbor	192.168.85.146	2CPU/2核 8G内存

2.所有服务器统一处理执行

2.1 关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

2.2 关闭selinux

sed -i 's/enforcing/disabled/' /etc/selinux/config  #永久
setenforce 0  #临时

2.3 关闭swap（k8s禁止虚拟内存以提高性能）

sed -ri 's/.*swap.*/#&/' /etc/fstab #永久
swapoff -a #临时

2.4 更新yum (看需要更新)

yum -y update

2.5 时间同步

yum install ntpdate -y	#若是没有这个工具的需要下载
ntpdate time.windows.com

2.6 安装wget、vim

yum install wget -y
yum install vim -y

2.7 更新Docker的yum源

wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo

2.8 查看Docker版本

yum list docker-ce --showduplicates|sort -r

2.9 下载docker

yum install docker-ce-20.10.9 -y

2.10 进入/etc目录创建docker目录

cd /etc
mkdir docker

2.11 配置国内镜像加速器

sudo vim /etc/docker/daemon.json

{"registry-mirrors" : ["https://q5bf287q.mirror.aliyuncs.com", "https://registry.docker-cn.com","http://hub-mirror.c.163.com"],"exec-opts": ["native.cgroupdriver=systemd"]
}

2.12 docker自动启动

systemctl enable docker.service

2.13 启动docker

sudo systemctl daemon-reload
service docker start

2.14 安装rz上传插件

yum install lrzsz

3.k8s服务器配置

3.1 添加k8s的阿里云yum源

cat > /etc/yum.repos.d/kubernetes.repo << EOF
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF

3.2 安装 kubeadm，kubelet 和 kubectl

yum install kubelet-1.23.6 kubeadm-1.23.6 kubectl-1.23.6 -y

3.3 k8s自启动

systemctl enable kubelet.service

3.4 查询是否安装成功

yum list installed | grep kubelet
yum list installed | grep kubeadm
yum list installed | grep kubectl

3.5 修改三台主机名(ip自行配置)

cat >> /etc/hosts << EOF
192.168.85.141 k8s-master
192.168.85.142 k8s-node1
192.168.85.143 k8s-node2
EOF

3.6 设置网桥参数

cat > /etc/sysctl.d/k8s.conf << EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sysctl --system  #生效

3.7 k8s-master主节点初始化

kubeadm init --apiserver-advertise-address=192.168.85.141 --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.23.6 --service-cidr=10.96.0.0/16 --pod-network-cidr=10.244.0.0/16

运行结果

Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:https://kubernetes.io/docs/concepts/cluster-administration/addons/Then you can join any number of worker nodes by running the following on each as root:kubeadm join 192.168.85.141:6443 --token 2pw233.jhsl6y1ysijtafc7 \--discovery-token-ca-cert-hash sha256:230fdb6f83dd9e81ff421e0be7d681de6df630501395c51e6376c76ca2df81ee 

根据结果提示在master主节点上执行

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

查询节点是否成功

[root@localhost etc]# kubectl get nodes
NAME         STATUS   ROLES                  AGE    VERSION
k8s-master   Ready    control-plane,master   107s   v1.23.6

提示：

如果没有显示k8s-master而是显示localhost.localdomain

那么就执行：

kubeadm reset

然后重新初始化操作！！

在node节点上执行添加操作

kubeadm join 192.168.85.141:6443 --token j4e0j9.e0ixp8ythubqguo0 \--discovery-token-ca-cert-hash sha256:27eb6ef95e8c8ecbef3913c7a0a6921ce3dcbaf10d6534d33ef102e26c984e3e

成功添加显示

[root@localhost etc]# kubeadm join 192.168.85.141:6443 --token 2pw233.jhsl6y1ysijtafc7 \
> --discovery-token-ca-cert-hash sha256:230fdb6f83dd9e81ff421e0be7d681de6df630501395c51e6376c76ca2df81ee

* Certificate signing request was sent to apiserver and a response was received.
* The Kubelet was informed of the new secure connection details.Run 'kubectl get nodes' on the control-plane to see this node join the cluster.

主节点执行

[root@localhost etc]# kubectl get nodes
NAME         STATUS   ROLES                  AGE     VERSION
k8s-master   Ready    control-plane,master   6m22s   v1.23.6
k8s-node1    Ready    <none>                 22s     v1.23.6
k8s-node2    Ready    <none>                 18s     v1.23.6

如果没有显示node节点的话

就在node节点上执行

kubeadm reset

然后重新kubeadm join操作

如果node节点无法使用kubectl get nodes,那么就在node节点执行以下命令

mkdir ~/.kube
vim ~/.kube/config
# 复制master节点的内容 cat ~/.kube/config
# 将内容添加到node节点刚才创建的config里面即可！！！

3.8 部署网络插件 用于节点之间的项目通讯

(在master上操作)

wget https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

有时候可能会下载失败

[root@k8s-master docker]# wget https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
--2023-01-05 16:28:08--  https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
正在解析主机 raw.githubusercontent.com (raw.githubusercontent.com)... 0.0.0.0, ::

将该文件放在master上，然后应用执行

kubectl apply -f kube-flannel.yml

运行结果

[root@localhost home]# ls
kube-flannel.yml
[root@localhost home]# kubectl apply -f kube-flannel.yml
namespace/kube-flannel created
clusterrole.rbac.authorization.k8s.io/flannel created
clusterrolebinding.rbac.authorization.k8s.io/flannel created
serviceaccount/flannel created
configmap/kube-flannel-cfg created
daemonset.apps/kube-flannel-ds created
[root@localhost home]# 

3.9 此时k8s集群初始化完毕 休息下

3.10 安装kuboard图形化管理工具

在master节点上执行

kubectl apply -f https://addons.kuboard.cn/kuboard/kuboard-v3.yaml

查询是否安装完毕

kubectl get pods -n kuboard
[root@localhost etc]# kubectl get pods -n kuboard
NAME                          READY   STATUS              RESTARTS   AGE
kuboard-etcd-lkxmn            0/1     ContainerCreating   0          30s
kuboard-v3-56b4b954c9-jl6qw   0/1     ContainerCreating   0          30s
[root@localhost etc]# kubectl get pods -n kuboard

kuboard-v3-56b4b954c9-jl6qw   0/1     ContainerCreating   0          31s

全部加载完毕之后，访问 http://192.168.85.141:30080

因为默认30080端口

账号：admin 密码：Kuboard123

4.配置Jenkins服务器

采用Docker compose安装,最开始安装docker的时候，docker compose会伴随安装

4.1 jenkins内部使用本地docker

进入/var/run,找到docker.sock

[root@npy run]# ls
auditd.pid  containerd   cryptsetup          dmeventd-client  docker.pid   initramfs  lvm          netreport       sepermit  sudo         tmpfiles.d  user
chrony      crond.pid    dbus                dmeventd-server  docker.sock  lock       lvmetad.pid  NetworkManager  setrans   syslogd.pid  tuned       utmp
console     cron.reboot  dhclient-ens33.pid  docker           faillock     log        mount        plymouth        sshd.pid  systemd      udev        xtables.lock
[root@npy run]# pwd
/var/run

修改docker.sock文件所属组

chown root:root docker.sock

修改权限

chmod o+rw docker.sock

4.2 配置Jenkins挂载目录

mkdir -p /home/jenkins/jenkins_mount
chmod 777 /home/jenkins/jenkins_mount

4.3 编写docker-compose.yml文件

浏览器访问端口配置为:10240

容器名称为：npy_jenkins

version: '3.1'
services:jenkins:image: jenkins/jenkinsprivileged: trueuser: rootports:- 10240:8080- 10241:50000container_name: npy_jenkinsvolumes:- /home/jenkins/jenkins_mount:/var/jenkins_home- /etc/localtime:/etc/localtime- /var/run/docker.sock:/var/run/docker.sock- /usr/bin/docker:/usr/bin/docker- /etc/docker/daemon.json:/etc/docker/daemon.json                                                    

4.4 先启动一下compose

docker compose up -d

4.5 配置下镜像加速

# 修改挂载目录的hudson.model.UpdateCenter.xml文件 添加清华源加速
[root@localhost jenkins_mount]# pwd
/home/jenkins/jenkins_mount
[root@localhost jenkins_mount]# ls
config.xml               docker-compose.yml        hudson.model.UpdateCenter.xml  jenkins.telemetry.Correlator.xml  nodeMonitors.xml  plugins     secret.key.not-so-secret  updates      users
copy_reference_file.log  failed-boot-attempts.txt  identity.key.enc               jobs                              nodes             secret.key  secrets                   userContent  war
[root@localhost jenkins_mount]# 

<?xml version='1.1' encoding='UTF-8'?>
<sites><site><id>default</id><url>https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json</url></site>
</sites>

4.6 获取Jenkins登录密码

cat /home/jenkins/jenkins_mount/secrets/initialAdminPassword

[root@localhost jenkins_mount]# cat /home/jenkins/jenkins_mount/secrets/initialAdminPassword
296fcfb8b0a04a4b8716e33b53fa6743

4.7 登录Jenkins

选择安装推荐的插件就可以了

http://192.168.85.144:10240

4.8 升级Jenkins

首先下载jenkins的war包

下载地址:2.375.3版本

然后停止jenkins容器，记得是停止！

# docker stop 677c9d9ab474
[root@localhost jenkins_mount]# docker ps
CONTAINER ID   IMAGE             COMMAND                   CREATED          STATUS          PORTS                                                                                        NAMES
677c9d9ab474   jenkins/jenkins   "/sbin/tini -- /usr/…"   27 minutes ago   Up 27 minutes   0.0.0.0:10240->8080/tcp, :::10240->8080/tcp, 0.0.0.0:10241->50000/tcp, :::10241->50000/tcp   npy_jenkins
[root@localhost jenkins_mount]# docker stop 677c9d9ab474
f1c11a1c592b
[root@localhost jenkins_mou

然后把下载的jenkins.war包通过rz拉到服务器上，然后执行docker cp命令

[root@localhost jenkins]# ls
jenkins_mount
[root@localhost jenkins]# rz 
[root@localhost jenkins]# ls
jenkins_mount  jenkins.war
[root@localhost jenkins]# docker cp jenkins.war 677c9d9ab474:/usr/share/jenkins/jenkins.war

Copying to container - 98.3kB
Copying to container - 131.1kB

再重新启动容器

docker start 677c9d9ab474

4.9 重新登录Jenkins获取升级版本

账号是：admin 密码是：123456

4.10 Jenkins下载以下插件

第一个是为了连接gitlab,第二个是为了ssh连接目标服务器

Git Parameter

Publish Over SSH

4.11 jenkins暂时完成

5. 配置Gitlab服务器

5.1 拉取镜像

docker pull gitlab/gitlab-ce

5.2 创建共享卷目录

[root@localhost gitlab]# mkdir etc
[root@localhost gitlab]# mkdir log
[root@localhost gitlab]# mkdir data
[root@localhost gitlab]# ls
data  etc  log
[root@localhost gitlab]# chmod 777 data/ etc/ log/

5.3 编写docker-compose.yml

version: '3.1'
services:gitlab:image: 'gitlab/gitlab-ce'restart: alwayscontainer_name: npy_gitlabprivileged: trueenvironment:GITLAB_OMNIBUS_CONFIG: |external_url 'http://192.168.85.145'ports:- '80:80'- '443:443'- '33:22'volumes:- '/home/gitlab/etc:/etc/gitlab'- '/home/gitlab/log:/var/log/gitlab'- '/home/gitlab/data:/var/opt/gitlab'

5.4 启动docker compose

docker compose up -d

5.5 docker命令启动

docker run -itd --name=npy_gitlab --restart=always --privileged=true   -p 8443:443  -p 80:80 -p 222:22 -v /home/gitlab/etc:/etc/gitlab -v  /home/gitlab/log:/var/log/gitlab -v  /home/gitlab/data:/var/opt/gitlab  gitlab/gitlab-ce

5.6 访问界面

http://192.168.85.145:80

用户名为：root

获取密码：进入容器查看

sudo docker exec -it gitlab grep 'Password:' /etc/gitlab/initial_root_password

5.7 切换中文

6. 配置Harbor镜像仓库

6.1 安装docker、docker-compose

yum install docker-ce-20.10.9 -y
yum install epel-release -y
yum install docker-compose –y

6.2 下载Harbor安装包

下载地址
下载会有点慢，建议用迅雷下载
下载的harbor-offline-installer-v1.10.10.tgz 包通过ftp工具拉取到服务器上

6.3 解压安装包

6.9 访问测试

浏览器输入ip即可

7.gitlab服务器连接Harbor

7.1 修改gitlab服务器的daemon.json

目的：将CI服务器上的项目push到镜像harbor私仓

insecure-registries为harbor服务器的ip

vim /etc/docker/daemon.json

{"registry-mirrors" : ["https://q5bf287q.mirror.aliyuncs.com", "https://registry.docker-cn.com","http://hub-mirror.c.163.com"],"exec-opts": ["native.cgroupdriver=systemd"],"insecure-registries": ["192.168.85.146"]
}

7.2 加载配置文件使其生效

systemctl daemon-reload

7.3 重启docker

systemctl restart docker

7.4 连接测试

测试登录harbor服务器

账号密码就是部署harbor时的账号密码：admin Harbor12345

[root@localhost docker]# docker login 192.168.85.146
Username: admin
Password: Harbor12345
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.

8.3 将公钥添加到gitlab中

登录gilab,点击用户设置界面，执行一下步骤，增加一个ssh密钥.

8.4 为Jenkins 添加全局凭据（私钥）

登录jenkins,打开系统管理-Manage Credentials进入凭据管理页面

8.5 拉取代码测试

• 先去在gitlab中创建一个项目 并上传项目 注意分支一定要是master分支

复制项目地址

设置完之后进行构建 输出成功

查看工作空间，发现有代码了

8.6 对 jenkins 的安全做一些设置

依次点击 系统管理-全局安全配置-授权策略，勾选"匿名用户具有可读权限

8.7 完成拉取功能

9.Jenkins安装Maven以及Jdk

9.1 首先拉取两个安装包到服务器上

[root@localhost jenkins]# rz[root@localhost jenkins]# ls
apache-maven-3.9.0-bin.tar.gz  docker-compose.yml  jdk-8u11-linux-x64.tar.gz  jenkins_mount  jenkins.war

9.2 解压Maven与Jdk并改名

[root@localhost jenkins]# ls
apache-maven-3.9.0  apache-maven-3.9.0-bin.tar.gz  docker-compose.yml  jdk1.8.0_11  jdk-8u11-linux-x64.tar.gz  jenkins_mount  jenkins.war
[root@localhost jenkins]# mv apache-maven-3.9.0 maven
[root@localhost jenkins]# ls
apache-maven-3.9.0-bin.tar.gz  docker-compose.yml  jdk1.8.0_11  jdk-8u11-linux-x64.tar.gz  jenkins_mount  jenkins.war  maven
[root@localhost jenkins]# mv jdk1.8.0_11/ jdk
[root@localhost jenkins]# ls
apache-maven-3.9.0-bin.tar.gz  docker-compose.yml  jdk  jdk-8u11-linux-x64.tar.gz  jenkins_mount  jenkins.war  maven
[root@localhost jenkins]# 

9.3 maven并进入解压文件修改setting.xml

位置：home/jenkins/maven/conf/setting.xml

• 添加阿里云镜像地址

 </mirrors><mirror><id>alimaven</id><name>aliyun maven</name><url>https://maven.aliyun.com/repository/public/</url><mirrorOf>central</mirrorOf></mirror></mirrors>

• 添加jdk8编译

</profiles><profile><id>jdk8</id><activation><activeByDefault>true</activeByDefault><jdk>1.8</jdk></activation><properties><maven.compiler.source>1.8</maven.compiler.source><maven.compiler.target>1.8</maven.compiler.target><maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion></properties></profile>
</profiles>

• 激活profile

<activeProfiles><activeProfile>jdk8</activeProfile></activeProfiles>

9.4 将jdk还有maven拉取到jenkins的挂载目录

[root@localhost jenkins]# ls
apache-maven-3.9.0-bin.tar.gz  docker-compose.yml  jdk  jdk-8u11-linux-x64.tar.gz  jenkins_mount  jenkins.war  maven
[root@localhost jenkins]# mv jdk /home/jenkins/jenkins_mount/
[root@localhost jenkins]# mv maven/ /home/jenkins/jenkins_mount/
[root@localhost jenkins]# ls
apache-maven-3.9.0-bin.tar.gz  docker-compose.yml  jdk-8u11-linux-x64.tar.gz  jenkins_mount  jenkins.war
[root@localhost jenkins]# 

9.5 进入jenkins容器

docker exec -it b5a49147b7f5 bash

找到jdk与maven的目录

/var/jenkins_home/jdk

/var/jenkins_home/maven

root@b5a49147b7f5:/var/jenkins_home# cd jdk/
root@b5a49147b7f5:/var/jenkins_home/jdk# ls

9.6 在jenkins的全局配置中配置jdk与maven

* 9.7 jenkins服务器创建一个jar包存放目录(好像没什么用…)

[root@localhost jenkins]# mkdir MavenJar
[root@localhost jenkins]# chmod 777 -R MavenJar/
[root@localhost jenkins]# ll

[root@localhost jenkins]# 

* 9.8 进入系统配置修改Publish over SSH

9.9 测试maven打包

在Job的构建里面Build Steps->调用顶层Maven目标

clean package -DiskpTest

应用保存之后重新构建，就会执行打包操作，第一次打包下载会有点慢，不要急哦。

10.创建流水线 连接K8s 实现CI/CD

10.0 jenkins配置k8s SSH Servers

在系统配置里面

记得在k8s master上创建 /usr/local/k8s目录 并且 chmod 777 k8s

10.1 创建项目，选择流水线，下面构建pipline脚本

10.2 写一个流水线脚本大致流程 （参考）

// 所有脚本命令都放在pipline中
pipeline{// 指定任务在哪个集群节点中执行agent any// 声明全局变量，方便使用environment {key = 'value'}stages {stage('拉取git仓库代码') {steps {echo '拉取git仓库代码 - SUCCESS'}}stage('通过maven构建项目') {steps {echo '通过maven构建项目 - SUCCESS'}}stage('通过Docker制作自定义镜像') {steps {echo '通过Docker制作自定义镜像 - SUCCESS'}}stage('将自定义镜像推送到harbor') {steps {echo '将自定义镜像推送到harbor - SUCCESS'}}stage('将yml文件传到k8s-master上') {steps {echo '将yml文件传到k8s-master上 - SUCCESS'}}stage('远程执行k8s-master的kubectl命令') {steps {echo '远程执行k8s-master的kubectl命令 - SUCCESS'}}}
}

10.3 流水线语法 – 拉取git仓库代码

checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[url: 'http://192.168.85.145/root/lover.git']]])

10.4 流水线语法 --通过maven构建项目

sh '/var/jenkins_home/maven/bin/mvn clean package -DskipTests'

10.5 流水线语法 --通过Docker制作自定义镜像

sh '''mv ./target/*.jar ./docker/lover_story.jar
docker build -t ${JOB_NAME}:${tag} ./docker/'''

10.5 流水线语法 – 将自定义镜像推送到harbor

这个需要修改私服在jenkins服务器的/etc/docker/daemon.json

{"registry-mirrors" : ["https://q5bf287q.mirror.aliyuncs.com", "https://registry.docker-cn.com","http://hub-mirror.c.163.com"],"exec-opts": ["native.cgroupdriver=systemd"],"insecure-registries": ["192.168.85.146"]
}

# 重新加载
systemctl daemon-reload
systemctl restart docker
docker swarm init

先docker登录harbor

然后给镜像打标签

之后进行推送到指定的仓库中

sh '''docker login -u ${harborUser} -p ${harborPassword} ${harborAddress}
docker tag ${JOB_NAME}:${tag} ${harborAddress}/${harborRepo}/${JOB_NAME}:${tag}
docker push ${harborAddress}/${harborRepo}/${JOB_NAME}:${tag}'''

10.6 流水线语法 – 将yml文件发送到master节点

• 让jenkins无密码连接到k8s

进入jenkins容器复制其公钥

root@b5a49147b7f5:~/.ssh# cat id_rsa.pub 
ssh-rsa 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 root@b5a49147b7f5
root@b5a49147b7f5:~/.ssh# 

• master节点配置jenkins公钥

将id_rsa.pub 内容添加进去即可

[root@k8s-master ~]# cd ~
[root@k8s-master ~]# ls
anaconda-ks.cfg
[root@k8s-master ~]# mkdir .ssh
[root@k8s-master ~]# cd .ssh/

10.7 流水线语法 – 远程执行k8s-master的kubectl命令

sh 'ssh root@192.168.85.141 kubectl apply -f lover.yml'

记得Master也要配置/etc/docker/dameon.json文件的私仓地址

10.8 最终流水线脚本

// 所有脚本命令都放在pipline中
pipeline{// 指定任务在哪个集群节点中执行agent any// 声明全局变量，方便使用environment {harborUser = 'admin'harborPassword = 'Harbor12345'harborAddress = '192.168.85.146'harborRepo = 'lover'}stages {stage('拉取git仓库代码') {steps {checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[url: 'http://192.168.85.145/root/lover.git']]])}}stage('通过maven构建项目') {steps {sh '/var/jenkins_home/maven/bin/mvn clean package -DskipTests'}}stage('通过Docker制作自定义镜像') {steps {sh '''mv ./target/*.jar ./docker/

}

10.9 运行流水线即可完成k8s部署

ip link set cni0 down && ip link set flannel.1 down 
ip link delete cni0 && ip link delete flannel.1
systemctl restart containerd && systemctl restart kubelet

错误

1.docker service ls出错

没有正确加载/etc/docker/dameon.json,会无法从harbor拉取镜像

因此在k8s集群上每个节点执行以下操作,前提是配置好了harbor的地址

docker swarm init

2.无法从harbor拉取镜像

看看是否镜像仓库是公开的！！私有的镜像仓库是需要配置密钥的！
