1. dev主机至gitlab-ce密钥配置
1.2 dev主机生成密钥对
# ssh-keygen
# cat /root/.ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD4kVDnVDU/K3bidZJQy6EiGkGrwUI/m7X5vuhZBepW0KaYOouznICuXqKxjc9kiSVv+rAKtP8AkQFJcbZM0ige5rS1LrsIkKIxbGW8hUDyrRuz1iTMl96Upk+FkG907RDrxFUGGkly9Ykjkhh0RRLNdrlw95zXXr4o9I2fCBHMa5u2cZCSVMACgTLnnn8ntE37b3Zrh4fHzFPhFK8SF/eyso8EJXXXfSXLjqZimr7Fb0AMgvLWa0OTTYmBessvS4aU0Fq4P6Kfiua6fJSBa0nn67UqZumUoTC/cUfYJyYk/FYavfEW/2OULBRZ9LyXNSpz97JhEZDBeDj+DBv0WO1/ root@dev

2.创建项目数据库
2.1 安装mysql （略）
2.2 创建业务库并授权
MySQL [(none)]> create database if not exists solo default charset utf8 collate utf8_general_ci;
Query OK, 1 row affected (0.02 sec)
MySQL [(none)]> grant all on solo.* to 'root'@'%' identified by "123456";
Query OK, 0 rows affected, 1 warning (0.05 sec)
MySQL [(none)]> grant all on solo.* to 'root'@'localhost' identified by "123456";
Query OK, 0 rows affected, 2 warnings (0.01 sec)
3.获取项目代码并修改
# 1.代码获取
# git clone --recurse-submodules https://gitee.com/dl88250/solo.git
#2.代码修改
# ls
solo
# vim solo/src/main/resources/local.properties 修改数据库信息

#### MySQL runtime #### 修改这里的信息
runtimeDatabase=MYSQL
jdbc.username=root
jdbc.password=123456
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.URL=jdbc:mysql://10.0.0.31:3306/solo?useUnicode=yes&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true
#### H2 runtime ####
#runtimeDatabase=H2
#jdbc.username=root
#jdbc.password=
#jdbc.driver=org.h2.Driver
#jdbc.URL=jdbc:h2:~/solo_h2/db;MODE=MYSQL
# The minConnCnt MUST larger or equal to 3
jdbc.minConnCnt=5
jdbc.maxConnCnt=10
# The specific table name prefix
jdbc.tablePrefix=b3_solo
4.项目代码上传到gitlab

git config --global user.name "Administrator"
git config --global user.email "admin@example.com"
[root@dev solo]# git remote remove origin
[root@dev solo]# git remote add origin git@10.0.0.102:root/solo.git 这里ip是gitlab的
[root@dev solo]# git add -A .
[root@dev solo]# git commit -m "new"
[master 96d18ba] new
1 file changed, 1 insertion(+), 1 deletion(-)
[root@dev solo]# git tag 1.0.0
[root@dev solo]# git push origin 1.0.0
[root@dev solo]# git push -u origin --all

5.构建项目运行基础应用容器镜像
在harbor主机上操作
5.1.创建项目目录
[root@harbor ~]# mkdir /tomcatdir
[root@harbor ~]# cd /tomcatdir/
5.2 生成Dockerfile文件
root@harbor tomcatdir]# echo "tomcat is running" >> index.html
[root@harbor ~]# tar xf jdk-8u231-linux-x64.tar.gz
[root@harbor ~]# mv jdk1.8.0_231 /tomcatdir/jdk
[root@harbor tomcatdir]# vim Dockerfile
FROM centos:centos7
MAINTAINER "www.zege.com"
ENV VERSION=8.5.81
ENV JAVA_HOME=/usr/local/jdk
ENV TOMCAT_HOME=/usr/local/tomcat
RUN yum -y install wget
RUN wget https://dlcdn.apache.org/tomcat/tomcat-8/v${VERSION}/bin/apache-tomcat-${VERSION}.tar.gz --no-check-certificate
RUN tar xf apache-tomcat-${VERSION}.tar.gz
RUN mv apache-tomcat-${VERSION} /usr/local/tomcat
RUN rm -rf apache-tomcat-${VERSION}.tar.gz /usr/local/tomcat/webapps/*
RUN mkdir /usr/local/tomcat/webapps/ROOT
ADD ./index.html /usr/local/tomcat/webapps/ROOT/
ADD ./jdk /usr/local/jdk
RUN echo "export TOMCAT_HOME=/usr/local/tomcat" >> /etc/profile
RUN echo "export JAVA_HOME=/usr/local/jdk" >> /etc/profile
RUN echo "export PATH=${TOMCAT_HOME}/bin:${JAVA_HOME}/bin:$PATH" >> /etc/profile
RUN echo "export CLASSPATH=.:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar" >> /etc/profile
RUN source /etc/profile
EXPOSE 8080
CMD ["/usr/local/tomcat/bin/catalina.sh","run"]
[root@harbor tomcatdir]# ls
Dockerfile index.html jdk
5.3 使用docker build构建容器镜像
[root@harbor tomcatdir]# docker build -t 10.0.0.10/library/tomcat:8581 .
5.4 构建时如果拉取基础镜像失败解决方法
#创建或修改 /etc/docker/daemon.json 文件，修改为如下形式
{
"registry-mirrors": [
"http://hub-mirror.c.163.com",
"https://docker.mirrors.ustc.edu.cn",
"https://registry.docker-cn.com"
]
}
# systemctl daemon-reload
# systemctl restart docker
5.5 推送镜像至harbor仓库
# docker push 10.0.0.10/library/tomcat:8581
5.6 验证容器镜像可用性
[root@harbor tomcatdir]# docker run -d 10.0.0.10/library/tomcat:8581
2881b67f14f65b407b1cd867918e11bbeffbd2a73197987fce72477414fafe65
[root@harbor tomcatdir]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

[root@harbor tomcatdir]# docker inspect 2881b67f14f6|grep IPAddress
"SecondaryIPAddresses": null,
"IPAddress": "172.17.0.2",
"IPAddress": "172.17.0.2",
[root@harbor tomcatdir]# curl 172.17.0.2:8080
tomcat is running
6.jenkins项目构建及发布
6.1 项目构建及发布步骤
第一步：jenkins从gitlab上拉取项目代码
第二步：jenkins对项目代码编译，由maven完成
第三步：jenkins使用docker对编译完成的项目代码进行打包，打包成容器应用镜像
第四步：jenkins把打包的容器应用镜像上传到harbor
第五步：jenkins通过ssh插件完成对web-server进行运行容器应用镜像的操作
6.2 创建项目任务
