|NO.Z.00050|——————————|^^ 操作 ^^|——|CI/CD&Jenkins_Harbor操作.V07|--------------------------------------------|Jenkins向docker中部署專案.V01|

一、CI/CD.Jenkins.Jenkins向docker中部署專案

### --- Jenkins構建Job

~~~     # 通過jenkins向docker主機中部署專案
~~~     ——>構建Maven風格的Job:程式碼地址：[email protected]:/home/git/easy-springmvc-maven.git
~~~     Dashboard——>新建Item——>任務名稱：maven-docker：構建一個maven專案——>
~~~     ——>Goals and options填寫：clean package -Dmaven.test.skip=true
~~~     ——>只有前面執行成功之後才會執行下面部分。

~~~     # 配置Post Steps

~~~     ——>指令碼中用到的倉庫和認證的賬號需要先在harbor新建好。

### --- 建立dockerfile：centos7.x 10.10.10.12 jenkins伺服器中配置
~~~     建立dockerfile

[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 <[email protected]>

# 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.
CMD ["catalina.sh", "run"]

# Expose ports.
EXPOSE 8080

~~~     # 解釋說明  
~~~     # 目的：是把新產生的war包增加到tomcat中去

FROM tomcat:8.0.36-alpine                                // 從官方下載tomcat8.0.36
MAINTAINER yanqi <[email protected]>                    // 作者：作者郵箱
ADD maven-docker-test.war /usr/local/tomcat/webapps/     // 從jenkins本地檔案系統拷貝它的war包到/usr/local/tomcat/webapps的目錄下；專案名稱是maven-docker  
ENV PATH /usr/local/tomcat/bin:$PATH                     // 設定環境變數
CMD ["catalina.sh", "run"]                               // 最後去執行
EXPOSE 8080                                              // 埠

二、Post setps.配置shell指令碼

### --- 該實驗環境yum安裝方式修改工作目錄後的指令碼
~~~     Jenkins機器：編譯完成後，build生成一個新版本的映象，push到遠端docker倉庫

# Variables
JENKINS_WAR_HOME='/var/lib/jenkins/workspace/maven-docker/target'
DOCKERFILE_HOME='/var/lib/jenkins/docker-file/maven-docker-test_war'
HARBOR_IP='10.10.10.11'
REPOSITORIES='jenkins/maven-docker'
HARBOR_USER='yanqi'
HARBOR_USER_PASSWD='Harbor12345'
HARBOR_USER_EMAIL='[email protected]'
 
# 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

### --- 配置檔案說明

JENKINS_WAR_HOME='/var/lib/jenkins/workspace/maven-docker/target'           // 定義環境變數：設定工作目錄
DOCKERFILE_HOME='/var/lib/jenkins/docker-file/maven-docker-test_war'        // dockerfile檔案建立，上面已經建立完成。
HARBOR_IP='10.10.10.11'                                                     // 定義harbor伺服器的地址
REPOSITORIES='jenkins/maven-docker'                                         // 庫的名字
HARBOR_USER='yanqi'                                                         // harbor倉庫的使用者名稱：yanqi
HARBOR_USER_PASSWD='Harbor12345'                                            // Harbor倉庫的密碼：Harbor12345
sudo docker login -u ${HARBOR_USER} -p ${HARBOR_USER_PASSWD} ${HARBOR_IP}:80  // jenkins主機登入harbor伺服器所用到的${HARBOR_USER}：Harbor主機的使用者 ${HARBOR_USER_PASSWD}主機的密碼 ${HARBOR_IP}:80主機的地址+埠
Login Succeeded                                                             //登入成功
IMAGE_ID=`sudo docker images | grep ${REPOSITORIES} | awk '{print $3}'`     // IMAGE_ID，通過awk拿去第三列。作為唯一的標識
sudo docker build -t ${HARBOR_IP}:80/${REPOSITORIES}:${TAG} . &>/dev/null   // .標識之前的那個目錄
sudo docker push ${HARBOR_IP}:80/${REPOSITORIES}:${TAG} &>/dev/null         //push的時候也需要埠號

三、Post setps.配置shell指令碼

### --- 該實驗環境war包安裝方式修改工作目錄後的指令碼（war包部署時所使用的的指令碼檔案）
~~~     Jenkins機器：編譯完成後，build生成一個新版本的映象，push到遠端docker倉庫
 
# Variables
JENKINS_WAR_HOME='/root/.jenkins/workspace/maven-docker-test/target'
DOCKERFILE_HOME='/root/jenkins/docker-file/maven-docker-test_war'
HARBOR_IP='10.10.10.11'
REPOSITORIES='jenkins/maven-docker-test'
HARBOR_USER='yanqi'
HARBOR_USER_PASSWD='Harbor12345'
HARBOR_USER_EMAIL='[email protected]'
 
# 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
