第4天 CI/CD+K8S综合实战

一、部署流程

1、研发push到github代码库

2、Jenkins 构建，pull git代码 使用maven进行编译打包

3、打包生成的代码，生成一个新版本的镜像，push到本地docker仓库harbor

4、发布，测试机器 pull 新版本的镜像，并删除原来的容器，重新运行新版本镜像。

5、部署环境：

git+jenkins(git+mvn+docker)habor+k8s

二、环境说明

服务及服务器说明-Aliyun环境

1、代码仓库           

  • github 或者 git-server 或者 gitlab

  • 本次实验使用github仓库 https://github.com/

2、环境规划

#2、容器镜像仓库 
// centos7.x 私有：10.10.10.11  公有：192.168.1.11           // harbor服务器
#3、CI/CD服务器
// centos7.x 私有：10.10.10.12 公有：192.168.1.12            // jenkins服务器
# 软件：
// jdk
// jenkins
// git
// maven
// docker
#4、应用服务器
// centos7.x 私有：10.10.10.13 公有：192.168.1.13            // docker服务器
# 软件：
// jq  
// docker  OR  k8s集群
#5、Git服务器
// centos7.x 私有：10.10.10.14 公有：192.168.1.14            // Git服务器

三、部署Harbor镜像仓库

1、下载安装

#在 centos7.x 10.10.10.11 192.168.1.11 Harbor服务器部署操作


#官方地址：https://github.com/goharbor/harbor/releases              //下载离线安装包：需要翻墙
[root@harbor ~]# wget -c https://storage.googleapis.com/harbor-releases/release-1.8.0/harbor-offline-installer-v1.8.0.tgz
yum -y install  lrzsz


#1、安装compose
[root@harbor ~]# curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   633    0   633    0     0   1010      0 --:--:-- --:--:-- --:--:--  1011
100 11.2M  100 11.2M    0     0  89656      0  0:02:11  0:02:11 --:--:--  133k
// uname -s：查看系统版本
// uname -m：查看的是CPU平台，CPU架构
// -o：存储路径
[root@harbor ~]# chmod +x /usr/local/bin/docker-compose 


#2、启动harbor之前先启动docker：对版本要求不是很严格。
//配置阿里云docker仓库
[root@harbor ~]# yum install -y yum-utils device-mapper-persitent-data lvm2 git
//安装docker扩展源
[root@harbor ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
OR
[root@harbor ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@harbor ~]# yum list docker-ce --showduplicates|sort -r          // 查看可以选择的docker版本
//安装docker
[root@harbor ~]# yum install -y docker-ce-17.06.0.ce-1.el7.centos.x86_64 
[root@harbor ~]# systemctl start docker
[root@harbor ~]# docker -v
Docker version 17.06.0-ce, build 02c1d87


#3、配置harbor
[root@harbor ~]# tar -zxvf harbor-offline-installer-v2.0.0-rc3.tgz 
[root@harbor ~]# cd harbor/
[root@harbor harbor]# cp harbor.yml.tmpl harbor.yml
[root@harbor harbor]# vim harbor.yml                       // 主机名要可以解析(需要部署dns服务器，用/etc/hosts文件没有用)，如果不可以解析，可以使用IP地址,需要修改的内容如下
hostname: 10.10.10.11
#https:                                                    //如果要用https这里就需要改，现在我们先不用https，这里不需要改
# https port for harbor, default is 443                    //注销https
# port: 443
# The path of cert and key files for nginx
#certificate: /your/certificate/path
#private_key: /your/private/key/path

如何重启harbor

[root@harbor ~]# cd harbor/
[root@harbor harbor]# docker-compose down
[root@harbor harbor]# vim harbor.yml
[root@harbor harbor]# ./prepare
[root@harbor harbor]# docker-compose up -d

【扩展】重置Harbor登陆密码

// harbor现使用postgresql 数据库。不再支持mysql
#注：卸载重新重新安装也不可以，原因是没有删除harbor的数据，harbor数据在/data/目录下边，如果真要重新安装需要将这个也删除，备份或者迁移，请使用这个目录的数据。


#harbor版本为：1.8.0
#官方的安装包为：harbor-offline-installer-v1.8.0.tgz


#具体步骤：
#1、进入[harbor-db]容器内部
[root@harbor ~]# docker exec -it harbor-db /bin/bash
postgres [ / ]$


#2、进入postgresql命令行，
postgres [ / ]$  psql -h postgresql -d postgres -U postgres          #这要输入默认密码：root123
Password for user postgres: root123  
postgres [ / ]$  psql -U postgres -d postgres -h 127.0.0.1 -p 5432      #或者用这个可以不输入密码。
psql (9.6.14)
Type "help" for help
#3、切换到harbor所在的数据库
postgres=# \c registry
You are now connected to database "registry" as user "postgres".


#4、查看harbor_user表
registry=# select * from harbor_user;
 user_id | username  |       email        |             password             |    realname    |    comment     | deleted | reset_uuid |               salt               | sysadmin_
flag |       creation_time        |        update_time         | password_version 
---------+-----------+--------------------+----------------------------------+----------------+----------------+---------+------------+----------------------------------+----------
-----+----------------------------+----------------------------+------------------
       2 | anonymous |                    |                                  | anonymous user | anonymous user | t       |            |                                  | f        
     | 2021-03-31 08:22:54.937769 | 2021-03-31 08:22:55.189956 | sha1
       1 | admin     |                    | 5705da1ab03816503271011bb6a80ce9 | system admin   | admin user     | f       |            | u4ymc25ssuvgupbivm9kdhijx4t2xl3r | t

#5、例如修改admin的密码，修改为初始化密码Harbor12345 ，修改好了之后再可以从web ui上再改一次。
registry=#  update harbor_user set password='5705da1ab03816503271011bb6a80ce9', salt='u4ymc25ssuvgupbivm9kdhijx4t2xl3r'  where username='admin';
UPDATE 1
#6、退出 \q 退出postgresql，exit退出容器。
registry=# \q
postgres [ / ]$ exit


#完成后通过WEB UI，就可以使用admin 、Harbor12345 这个密码登录了，记得修改这个默认密码哦，避免安全问题。
#有更加狠点的招数，将admin账户改成别的名字，减少被攻击面：
registry=# update harbor_user set username='yanqi' where user_id=1;             #更改admin用户名为yanqi

3、Dockerfile文件

#在 centos7.x 10.10.10.12 jenkins服务器中配置
[root@jenkins ~]# mkdir -p /root/jenkins/docker-file/maven-docker-test_war
[root@jenkins ~]# vim /root/jenkins/docker-file/maven-docker-test_war/Dockerfile
# Version 1.0
# Base images.
FROM tomcat:8.0.36-alpine


# Author.
MAINTAINER yanqi <yanqi_vip@yeah.net>


# Add war.
ADD maven-docker-test.war /usr/local/tomcat/webapps/


# Define working directory.
WORKDIR /usr/local/tomcat/bin/


# Define environment variables.
ENV PATH /usr/local/tomcat/bin:$PATH


# Define default command.
CMD ["catalina.sh", "run"]


# Expose ports.
EXPOSE 8080

4、Harbor权限相关

harbor仓库的权限得配置一下，不然curl命令访问不到

四、业务服务器

1、安装软件

#在centos7.x 10.10.10.13 192.168.1.13 docker应用服务器部署。


#1、部署docker
[root@docker ~]# yum install -y yum-utils device-mapper-persitent-data lvm2 git
//安装docker扩展源
[root@docker ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
OR
[root@docker ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@docker ~]# yum list docker-ce --showduplicates|sort -r        #查看可以选择的docker版本
//安装docker
[root@docker ~]# yum install -y docker-ce-17.06.0.ce-1.el7.centos.x86_64
[root@docker ~]# systemctl start docker
[root@docker ~]# docker -v
Docker version 17.06.0-ce, build 02c1d87


# 安装jq
# jq官网：https://github.com/stedolan/jq/releases/download/jq-1.5/jq-1.5.tar.gz
[root@docker ~]# wget -c https://github.com/stedolan/jq/releases/download/jq-1.5/jq-1.5.tar.gz 
[root@docker ~]# tar -zxvf jq-1.5.tar.gz 
[root@docker ~]# cd jq-1.5
[root@docker jq-1.5]# yum install -y gcc*
[root@docker jq-1.5]# ./configure && make && sudo make install
// 后面的脚本会用到,jq类似于sed/awk专门处理json格式的文件

2、预先配置

#在centos7.x 10.10.10.13 192.168.1.13 docker业务机器上配置：
[root@docker ~]# visudo                                    #为了后期配置执行脚本，否则没有执行权限
#Defaults    requiretty
Defaults:root !requiretty


# 否则在机器业务机器上执行脚本时会报错：
[SSH] executing...
sudo: sorry, you must have a tty to run sudo
docker: invalid reference format.

五、Jenkins服务部署配置

1、软件安装

#在centos7.2 10.10.10.12 192.168.1.12 jenkins服务器配置


[root@jenkins ~]# wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
[root@jenkins ~]# rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
[root@jenkins ~]# yum install -y jenkins git maven
[root@jenkins ~]# java -version                            #查看java是否已经安装
openjdk version "1.8.0_282"
OpenJDK Runtime Environment (build 1.8.0_282-b08)
OpenJDK 64-Bit Server VM (build 25.282-b08, mixed mode) 
[root@jenkins ~]# systemctl start jenkins
[root@jenkins ~]# ps -ef|grep jenkins
jenkins   20817      1 99 21:40 ?        00:00:15 /etc/alternatives/java -Dcom.sun.akuma.Daemon=daemonized -Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins -jar /usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log --webroot=/var/cache/jenkins/war --daemon --httpPort=8080 --debug=5 --handlerCountMax=100 --handlerCountMaxIdle=20
root      20854  20503  0 21:40 pts/0    00:00:00 grep --color=auto jenkins
#查看启动的8080端口
[root@jenkins ~]# lsof -i:8080
COMMAND   PID    USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java    20817 jenkins  147u  IPv6  94236      0t0  TCP *:webcache (LISTEN)

2、预先配置

#由于在Jenkins机器上docker是使用root用户运行的，而Jenkins是使用普通用户jenkins运行的，所以要先配置下jenkins用户可以使用docker命令。
[root@docker ~]# visudo
jenkins ALL=(root)      NOPASSWD: /usr/bin/docker
#另外在Jenkins机器上配置：
Disable "ssh hostname sudo <cmd>", because it will show the password in clear.
        You have to run "ssh -t hostname sudo <cmd>".
#Defaults    requiretty
Defaults:jenkins !requiretty
#确认
[root@docker ~]# which docker                               #通过该命令查看docker的命令是否在/usr/bin/下
/usr/bin/docker  


#如果不配置这个，在执行下面脚本时，会报错误：
+ cp -f /home/jenkins/.jenkins/workspace/godseyeBranchForNov/godseye-container/target/godseye-container-wisedu.war /home/jenkins/docker-file/godseye_war/godseye.war
+ sudo docker login -u jkzhao -p Wisedu123 -e 01115004@wisedu.com 172.16.206.32
sudo: sorry, you must have a tty to run sudo

3、安装插件

  • 浏览器登录Jenkins：

    • http://10.10.10.12:8080，

    • http://192.168.1.12:8080进行初始化配置

  • 点击“系统管理”，点击“管理插件”，搜索插件"Maven Integration"和"SSH"，进行安装。



  • SSH安装完成后为：SSH Plugin

查看初始化密码

[root@jenkins ~]# cat /var/lib/jenkins/secrets/initialAdminPassword
4a19650966bb42978f33f7f5e879644b

4、配置远程机器：登录Jenkins，点击“Credentials”，点击“Add domain”。

  Dashboard——>Manage Jenkins——>Manage Credentials——>Jenkins:添加域：域名/描述/OK——>返回到添加凭据域列表——>docker——>添加凭据——>添加一些凭据——>确定——>END

点击“系统管理”，“系统配置”，找到“SSH remote hosts”。

Dashboard——>Manage Jenkins——>Configure System——>SSH remote hosts——>Check connection——>保存——>END

——>部署git服务器<——

1、部署GIT

#在centos7.x 10.10.10.14 git 服务器                                             // 服务器进行如下操作


#1.1、安装 git服务器端
[root@git ~]# yum install -y git
// 创建git用户并设置密码为1qaz2wsx（为开发人员拉代码时设置的用户）
[root@git ~]# useradd git

#1.5、补充：配置免秘钥
#1.5.1、10.10.10.12 客户端配置公钥
[root@jenkins ~]# ssh-keygen
[root@jenkins ~]# cat /root/.ssh/id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCqyWhdWhod3fz9YNygWhnQjXpZ4lko7SivNATIy1vVgyouEXkFeW2VujpxRU3VCvMXxO7C67iefahnLFm5UX4ZJTDzl9gXblzD3/GhJ0QL2BIjXidY0+eqtNYSx0bxvnYl9sCPXae9S0GyVmIfDyTh6gqWkusTvI3lIu4tfYfn4Y6W2ovBq+Cf/2oe1cFe6jtJnIscA2PeliOT90Gw3Y9wDRm/T1BE+V9Vr1kZ0kvTja+0zKd37sXL2oJwNnECK/kAgV7Paan3WdD9WQ4MhzWPMeuiPbf8MWBKssu8ZRnpQ5ZD4GcYQXqYLR5E3Kslpo9lsbXwpXBSOv4e/lg4Y6B7 root@jenkins


#1.5.2、10.10.10.14 git 服务器进行配置
[root@git ~]# su - git
[git@git ~]$ mkdir -p .ssh/
[git@git ~]$ chmod 700 .ssh/                                               // 给予目录700权限

#免密拉取测试
[root@jenkins ~]# git clone git@10.10.10.14:/home/git/easy-springmvc-maven.git


#2、无法建立连接解决方案
// 更改jenkins用户为root用户；
// 更改jenkins用户为正常的普通用户/bin/bash，将其的公钥加入到git服务器的git用户中。
// 此处暂时先用第一种解决办法，更改 jenkins 的运行用户为 root 用户，通过如下方式进行更改：
// 将/etc/sysconfig/jenkins文件由
[root@jenkins ~]# vim /etc/sysconfig/jenkins
JENKINS_USER="jenkins"
// 改为
JENKINS_USER="root"    
// 然后再重启即可。
[root@jenkins ~]# systemctl restart jenkins.service 


#报错：无法连接仓库：Invalid remote URL: git clone git@10.10.10.13:/home/git/repos/app.git
// 解决方案：配置秘钥

——>maven报错解决<——

#maven报错
#Dashboard——>maven-docker项目
// Build
//Maven Version
Jenkins needs to know where your Maven is installed.
Please do so from the tool configuration.
#解决方案
#Dashboard——>全局工具配置——>Maven安装——>name:maven3.0.5——>MAVEN_HOME：/usr/share/maven


#查看maven的安装地址
[root@jenkins ~]# which mvn
/usr/bin/mvn

六、Jenkins构建Job（通过jenkins向docker主机中部署项目）

1、构建Maven风格的Job:代码地址：git@10.10.10.14:/home/git/easy-springmvc-maven.git

Dashboard——>新建Item——>任务名称：maven-docker：构建一个maven项目——>

Goals and options填写：clean package -Dmaven.test.skip=true

只有前面执行成功之后才会执行下面部分。

2、配置Post Steps

注：脚本中用到的仓库和认证的账号需要先在harbor新建好。

——>配置dockerfile文件<——

#在 centos7.x 10.10.10.12 jenkins服务器中配置


[root@jenkins ~]# mkdir -pv /var/lib/jenkins/docker-file/maven-docker-test_war
[root@jenkins ~]# vim /var/lib/jenkins/docker-file/maven-docker-test_war/Dockerfile
# Version 1.0
# Base images.
FROM tomcat:8.0.36-alpine


# Author.
MAINTAINER yanqi <yanqi_vip@yeah.net>


# Add war.
ADD maven-docker.war /usr/local/tomcat/webapps/


# Define working directory.
WORKDIR /usr/local/tomcat/bin/


# Define environment variables.
ENV PATH /usr/local/tomcat/bin:$PATH


# Define default command.

ADD maven-docker-test.war /usr/local/tomcat/webapps/                 // 从jenkins本地文件系统拷贝它的war包到/usr/local/tomcat/webapps的目录下；项目名称是maven-docker  
ENV PATH /usr/local/tomcat/bin:$PATH                        // 设置环境变量
CMD ["catalina.sh", "run"]                                  // 最后去执行
EXPOSE 8080                                                 // 端口
#目的：是把新产生的war包增加到tomcat中去

——>Post Steps.配置shell脚本<——

本次实验yum安装方式修改工作目录后的脚本：

# Jenkins机器：编译完成后，build生成一个新版本的镜像，push到远程docker仓库

# Delete image early version.
sudo docker login -u ${HARBOR_USER} -p ${HARBOR_USER_PASSWD} ${HARBOR_IP}
IMAGE_ID=`sudo docker images | grep ${REPOSITORIES} | awk '{print $3}'`

sudo docker build -t ${HARBOR_IP}/${REPOSITORIES}:${TAG} . &>/dev/null


# Push to the harbor registry.
sudo docker push ${HARBOR_IP}/${REPOSITORIES}:${TAG} &>/dev/null

注：yanqi包的名字为git项目的名字

5、验证是否部署成功：在docker应用服务器上查看

[root@docker ~]# docker images
REPOSITORY                            TAG                 IMAGE ID            CREATED              SIZE

六、Jenkins构建Job（通过jenkins向ks8集群中部署项目）

——>Execute shell script on remote host using ssh.远程站点配置文件<——

Harbor2.0的API发生了变化，此处是新版脚本方式，修改了镜像tag获取的方式

# 拉取镜像，发布
HARBOR_IP='10.10.10.11'
REPOSITORIES='jenkins/maven-docker'
HARBOR_USER='yanqi'
HARBOR_USER_PASSWD='Harbor12345'


# 登录harbor
docker login -u ${HARBOR_USER} -p ${HARBOR_USER_PASSWD} ${HARBOR_IP}:80


# Stop container, and delete the container.
CONTAINER_ID=`docker ps | grep "maven-docker" | awk '{print $1}'`
if [ -n "$CONTAINER_ID" ]; then
    docker stop $CONTAINER_ID
    docker rm $CONTAINER_ID
else #如果容器启动时失败了，就需要docker ps -a才能找到那个容器
    CONTAINER_ID=`docker ps -a | grep "maven-docker" | awk '{print $1}'`
    if [ -n "$CONTAINER_ID" ]; then  # 如果是第一次在这台机器上拉取运行容器，那么docker ps -a也是找不到这个容器的
        docker rm $CONTAINER_ID
    fi
fi


# Delet eeasy-springmvc-maven image early version.
IMAGE_ID=`sudo docker images | grep ${REPOSITORIES} | awk '{print $3}'`
if [ -n "${IMAGE_ID}" ];then
    docker rmi ${IMAGE_ID}
fi


# Pull image.
# TAG=`curl -s http://${HARBOR_IP}/api/repositories/${REPOSITORIES}/tags | jq '.[-1]' | sed 's/\"//g'`
# TAG=`curl -s http://10.10.10.11/api/repositories/jenkins/maven-docker/tags | jq '.[-1]| {name:.name}' | awk -F '"' '/name/{print $4}'`
TAG=`curl -s http://10.10.10.11/api/v2.0/projects/jenkins/repositories/maven-docker/artifacts |awk -F'name":"' '{print $2}'|cut -d '"' -f1`
docker pull ${HARBOR_IP}:80/${REPOSITORIES}:${TAG} &>/dev/null


# Run.
docker run -d --name maven-docker -p 8080:8080 ${HARBOR_IP}:80/${REPOSITORIES}:${TAG}
kubectl set image


#配置说明：
// kubectl set image+port的名字+镜像的名字即可：（只需要把k8s中的镜像替换掉即可）
#其它的部署流程不会发生变化。

七、报错处理：

#错误一：
// 错误现象：
+ cp -f /var/lib/jenkins/workspace/maven-docker/target/easy-springmvc-maven.war /var/lib/jenkins/docker-file/maven-docker-test_war/maven-docker.war
+ sudo docker login -u yanqi -p Harbor12345 10.10.10.11:80
++ grep jenkins/maven-docker
+ cd /var/lib/jenkins/docker-file/maven-docker-test_war
+ sudo docker build -t 10.10.10.11:80/jenkins/maven-docker:20210401-144031 .
Build step 'Execute shell' marked build as failure          #脚本文件未能执行，权限被拒绝，需要给新建的目录授予读写权限
// 解决方案:
[root@jenkins ~]# cd /var/lib/jenkins
[root@jenkins jenkins]# chmod 777 docker-file/ -R
[root@jenkins jenkins]# ll docker-file/
drwxrwxrwx 2 root root 48 Apr  1 21:11 maven-docker-test_war


#错误二：
// 错误现象：
+ sudo docker build -t 10.10.10.11:80/jenkins/maven-docker:20210401-205209 .
Build step 'Execute shell' marked build as failure
Finished: FAILURE
#解决方案：
// 查看dock而file文件是不是配置有问题：该环境排查是
[root@jenkins maven-docker-test_war]# cat Dockerfile 
ADD maven-docker-test.war /usr/local/tomcat/webapps/
// 改为
ADD maven-docker.war /usr/local/tomcat/webapps/


#错误三：
// 错误现象：
Error response from daemon: Get https://10.10.10.11:80/v2/: http: server gave HTTP response to HTTPS client
parse error: Invalid numeric literal at line 1, column 10
docker: invalid reference format.
// 解决方案：#在docker应用服务器上修改对仓库的安全配置。
[root@docker ~]# vim /etc/docker/daemon.json
{ "insecure-registries":["10.10.10.11:80"] }
// 重启docker
[root@docker ~]# systemctl restart docker
