CI/CD + docker 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。

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、容器镜像仓库

​ ip:

​ 公 161.117.37.192

​ 私 172.21.39.43

​ 主机名：harbor

3、CI/CD服务器

​ ip：

​ 公 161.117.34.103

​ 私 172.21.39.44

​ 主机名：jenkins

​ 软件：

​ jdk

​ jenkins

​ git

​ maven

​ docker

4、应用服务器

​ ip：172.21.39.45

​ 主机名：docker

​ 软件：

​ jq

​ docker

​ 或者 k8s集群

三、部署Harbor镜像仓库

1、下载安装

官方地址：
	https://github.com/goharbor/harbor/releases

下载离线安装包：需要FQ
# wget https://storage.googleapis.com/harbor-releases/release-1.8.0/harbor-offline-installer-v1.8.0.tgz
# yum -y install  lrzsz

安装compose
# curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

# chmod +x /usr/local/bin/docker-compose

# tar xf harbor-offline-installer-v1.8.0.tgz

配置harbor
# cd 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 = 192.168.1.200
ui_url_protocol = 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）
# ./install.sh

浏览器访问测试：http://192.168.1.200

创建仓库

创建账户

项目授权

2、测试Harbor

上传测试

[root@qfedu.com ~]# vim /etc/docker/daemon.json
 { "insecure-registries":["172.21.39.43:80"] }
 
[root@jenkins ~]# docker login 172.21.39.43:80
    Username: wing
    Password:

在web界面中查看镜像是否被上传到仓库中

如何重启harbor

# docker-compose down
# vim harbor.yml
# ./prepare
# 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
     # docker exec -it harbor-db /bin/bash

2、进入postgresql命令行，
     psql -h postgresql -d postgres -U postgres  #这要输入默认密码：root123 。
     psql -U postgres -d postgres -h 127.0.0.1 -p 5432  #或者用这个可以不输入密码。

3、切换到harbor所在的数据库
     # c registry

4、查看harbor_user表
     # select * from harbor_user;

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。
     # update harbor_user set password='a71a7d0df981a61cbb53a97ed8d78f3e', salt='ah3fdh5b7yxepalg9z45bu8zb36sszmr'  where username='admin';

6、退出 q 退出postgresql，exit退出容器。
     # q 
     # 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：
     # update harbor_user set username='wing' where user_id=1;              #更改admin用户名为wing

3、Dockerfile文件

# cd /root/jenkins/docker-file/maven-docker-test_war
# vim Dockerfile
# Version 1.0
# Base images. 
FROM tomcat:8.0.36-alpine

# Author.
MAINTAINER wing <276267003@qq.com>

# 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

# yum install docker jq -y   //后面的脚本会用到,jq类似于sed/awk专门处理json格式的文件
# systemctl start docker

2、预先配置

在业务机器上配置：
# visudo
#
#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

[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 ~]# systemctl start jenkins
[root@jenkins ~]# ps -ef|grep jenkins

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@jenkins ~]# 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

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://161.117.34.103:8080，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。

4、配置远程机器

登录Jenkins，点击“Credentials”，点击“Add domain”。

点击“系统管理”，“系统配置”，找到“SSH remote hosts”。

六、Jenkins构建Job

1、构建Maven风格的Job

代码地址： https://github.com/yanqiang20172017/easy-springmvc-maven.git

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

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。

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
 
# Variables
JENKINS_WAR_HOME='/var/lib/jenkins/workspace/maven-docker/target'
DOCKERFILE_HOME='/var/lib/jenkins/docker-file/maven-docker-test_war'
HARBOR_IP='172.21.39.43'
REPOSITORIES='jenkins/maven-docker'
HARBOR_USER='wing'
HARBOR_USER_PASSWD='Harbor12345'
HARBOR_USER_EMAIL='276267003@qq.com'
 
# Copy the newest war to docker-file directory.
cp -f ${JENKINS_WAR_HOME}/easy-springmvc-maven.war ${DOCKERFILE_HOME}/maven-docker.war
 
# Delete image early version.
sudo docker login -u ${HARBOR_USER} -p ${HARBOR_USER_PASSWD} ${HARBOR_IP}:80 
IMAGE_ID=`sudo docker images | grep ${REPOSITORIES} | awk '{print $3}'`
if [ -n "${IMAGE_ID}" ];then
    sudo docker rmi ${IMAGE_ID}
fi
 
# Build image.
cd ${DOCKERFILE_HOME}
TAG=`date +%Y%m%d-%H%M%S`
sudo docker build -t ${HARBOR_IP}:80/${REPOSITORIES}:${TAG} . &>/dev/null
 
# Push to the harbor registry.
sudo docker push ${HARBOR_IP}:80/${REPOSITORIES}:${TAG} &>/dev/null

之前war包方式部署的jenkins里面的脚本：

# 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
 
# Variables
JENKINS_WAR_HOME='/root/.jenkins/workspace/maven-docker-test/target'
DOCKERFILE_HOME='/root/jenkins/docker-file/maven-docker-test_war'
HARBOR_IP='172.22.211.175'
REPOSITORIES='jenkins/maven-docker-test'
HARBOR_USER='wing'
HARBOR_USER_PASSWD='Harbor12345'
HARBOR_USER_EMAIL='276267003@qq.com'
 
# Copy the newest war to docker-file directory.
cp -f ${JENKINS_WAR_HOME}/easy-springmvc-maven.war ${DOCKERFILE_HOME}/maven-docker-test.war
 
# 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 $3}'`
if [ -n "${IMAGE_ID}" ];then
    sudo docker rmi ${IMAGE_ID}
fi
 
# Build image.
cd ${DOCKERFILE_HOME}
TAG=`date +%Y%m%d-%H%M%S`
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：war包的名字为git项目的名字
/root/.jenkins/workspace/maven-docker-test/target/easy-springmvc-maven.war

拉取镜像、发布

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='172.21.39.43'
REPOSITORIES='jenkins/maven-docker'
HARBOR_USER='wing'
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://172.21.39.43/api/repositories/jenkins/maven-docker/tags | jq '.[-1]| {name:.name}' | awk -F '"' '/name/{print $4}'`
TAG=`curl -s http://161.117.37.192/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}

这是旧版本的脚本

# 拉取镜像，发布
HARBOR_IP='172.22.211.175'
REPOSITORIES='jenkins/maven-docker-test'
HARBOR_USER='wing'
HARBOR_USER_PASSWD='Harbor12345'
 
# 登录harbor
docker login -u ${HARBOR_USER} -p ${HARBOR_USER_PASSWD} ${HARBOR_IP}
 
# Stop container, and delete the container.
CONTAINER_ID=`docker ps | grep "maven-docker-test" | 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-test" | 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
 
# Deleteeasy-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://172.22.211.175/api/repositories/jenkins/maven-docker-test/tags | jq '.[-1]| {name:.name}' | awk -F '"' '/name/{print $4}'`
docker pull ${HARBOR_IP}/${REPOSITORIES}:${TAG} &>/dev/null
 
# Run.
docker run -d --name maven-docker-test -p 8080:8080 ${HARBOR_IP}/${REPOSITORIES}:${TAG}
kubectl set image
