基于docker容器DevOps应用方案

环境

主机名	IP地址	功能	安装的软件	系统版本
gitlab.server	192.168.179.13	本地代码仓库	gitlab-ce	centos8
jenkins.server	192.168.179.14	编译代码、打包镜像、项目发布	jenkins、docker、git、maven	centos8
harbor.server	192.168.179.15	本地容器镜像仓库（存储镜像）	harbor、docker-compose、docker	centos8
docker	192.168.179.16	制作镜像、上传镜像	docker	centos8
webs	192.168.179.10	测试环境（项目发布在此主机）	docker	centos8

基础配置

1.所有主机永久关闭防火墙和selinux

bash 复制代码

//永久关闭防火墙
systemctl disable --now firewalld.service 

//永久关闭selinux
setenforce 0
sed -i 's/^SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

2.配置yum源

所有主机配置对应系统的yum源，gitlab主机需要安装epel源

bash 复制代码

//删除自带的默认yum源
rm -rf /etc/yum.repos.d/*

//配置国内yum源（阿里云源）
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo


//安装epel源
yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm

sed -i 's|^#baseurl=https://download.example/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*

sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*

3.docker的安装教程

不是每一台都要安装docker

bash 复制代码

//centos系统安装docker过程（不是每一台都要装）
yum install -y yum-utils device-mapper-persistent-data lvm2

yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo

yum makecache

yum -y install docker-ce

systemctl enable --now docker.service

配置主机名与IP地址解析

所有主机都写在/etc/hosts 文件里面添加如下内容

bash 复制代码

//编辑 /etc/hosts 文件
[root@gitlab ~]# vi /etc/hosts 
[root@gitlab ~]# cat /etc/hosts 
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
#添加如下内容
192.168.179.13	gitlab.server
192.168.179.14	jenkins.server
192.168.179.15	harbor.server
192.168.179.16	docker
192.168.179.10	webs
[root@gitlab ~]#

部署gitlab.server主机

1.安装gitlab

安装和使用的详细过程请阅读GitLab版本控制

powershell 复制代码

//安装依赖包
[root@gitlab ~]# yum -y install git wget curl vim openssh-server openssh-clients postfix cronie perl

//启动postfix并设置开机自启
[root@gitlab ~]# systemctl enable --now postfix
 

//下载并安装policycoreutils-python
[root@gitlab ~]# wget http://mirror.centos.org/centos/7/os/x86_64/Packages/policycoreutils-python-2.5-34.el7.x86_64.rpm

[root@gitlab ~]# rpm -ivh --nodeps policycoreutils-python-2.5-34.el7.x86_64.rpm --force 


//下载gitlab软件包
[root@gitlab ~]# wget https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-16.4.1-ce.0.el7.x86_64.rpm

[root@gitlab ~]# rpm -ivh gitlab-ce-16.4.1-ce.0.el7.x86_64.rpm

4.验证web页面

安装完毕

部署jenkins.server主机

安装与使用的详细过程请阅读Jenkins部署与应用

1.部署tomcat

Jenkins是一个Java程序，所以要依赖tomcat

bash 复制代码

//安装Java环境
[root@jenkins ~]# yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel wget
[root@jenkins ~]# java -version
openjdk version "1.8.0_312"
OpenJDK Runtime Environment (build 1.8.0_312-b07)
OpenJDK 64-Bit Server VM (build 25.312-b07, mixed mode)
[root@jenkins ~]# 

//下载tomcat软件包
[root@jenkins ~]# wget https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.79/bin/apache-tomcat-9.0.79.tar.gz
[root@jenkins ~]# ls
anaconda-ks.cfg  apache-tomcat-9.0.79.tar.gz

//解压部署，解压到哪个目录，该目录就是安装目录
[root@jenkins ~]# tar -xf apache-tomcat-9.0.79.tar.gz -C /usr/local/
[root@jenkins ~]# cd /usr/local/
[root@jenkins local]# ls
apache-tomcat-9.0.79  etc    include  lib64    sbin   src
bin                   games  lib      libexec  share

//软链接
[root@jenkins local]# ln -s apache-tomcat-9.0.79/ tomcat
[root@jenkins local]# ls
apache-tomcat-9.0.79  etc    include  lib64    sbin   src
bin                   games  lib      libexec  share  tomcat

[root@jenkins local]#

2.安装jenkins

bash 复制代码

//安装Jenkins所需要的Java17
[root@jenkins ~]# yum -y install java-17-openjdk java-17-openjdk-devel

//由于安装tomcat时安装的Java1.8，但是Jenkins需要Java17，所以切换一下Java版本
[root@jenkins ~]# alternatives --config java

There are 2 programs which provide 'java'.

  Selection    Command

[root@jenkins ~]# java -jar jenkins.war

//把Jenkins包cp到 /usr/local/tomcat/webapps/去
[root@jenkins ~]# cp jenkins.war /usr/local/tomcat/webapps/

//重启tomca服务，就会自动解压Jenkins.war
[root@jenkins ~]#/usr/local/tomcat/bin/shutdown.sh
[root@jenkins ~]#/usr/local/tomcat/bin/startup.sh

[root@jenkins ~]# cd /usr/local/tomcat/webapps/
[root@jenkins webapps]# ls
docs  examples  host-manager  jenkins  jenkins.war  manager  ROOT

3.验证web页面

查看临时密码，登录进去，后面会重新设置一个管理员密码的

bash 复制代码

[root@jenkins ~]# cat /root/.jenkins/secrets/initialAdminPassword
fc67568de10348528e5735461cde70d9

建议直接安装全部插件

额外安装ssh、maven integration插件

4.安装git、maven、docker

bash 复制代码

//安装git
[root@jenkins ~]# yum -y install git

//安装maven
[root@jenkins ~]# yum -y install maven

//验证
[root@jenkins ~]# git version
git version 2.27.0

[root@jenkins ~]# mvn -v

OS name: "linux", version: "4.18.0-499.el8.x86_64", arch: "amd64", family: "unix"
[root@jenkins ~]#

5.安装docker

bash 复制代码

[root@jenkins ~]# yum install -y yum-utils device-mapper-persistent-data lvm2

[root@jenkins ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

[root@jenkins ~]# sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo

[root@jenkins ~]# yum makecache

[root@jenkins ~]# yum -y install docker-ce

[root@jenkins ~]# systemctl enable --now docker.service

6.配置免密登录

配置Jenkins主机可以从harbor主机拉取镜像，以及免密登录

bash 复制代码

//配置可以拉取harbor的镜像
[root@jenkins ~]# vi /etc/docker/daemon.json
[root@jenkins ~]# cat /etc/docker/daemon.json
{
    "insecure-registries": ["harbor.server"]
}
[root@jenkins ~]#



//配置免密登录，先生成密钥
[root@jenkins ~]# ssh-keygen -t rsa

[root@harbor harbor]# ./prepare 
[root@harbor harbor]# ./install.sh

2.访问web页面

安装完毕

部署docker主机

1.安装docker服务

bash 复制代码

//安装docker，前面有教程
...

//配置连接harbor-server所有镜像仓库
[root@docker ~]# vim /etc/docker/daemon.json
[root@docker ~]# cat /etc/docker/daemon.json
{
    "insecure-registries": ["harbor.server"]
}
[root@docker ~]# 
[root@docker ~]# systemctl daemon-reload 
[root@docker ~]# systemctl restart docker.service

2.制作一个基础的tomcat镜像，并上传到私有镜像仓库

bash 复制代码

//制作tomcat镜像，并上传到harbor-server主机
[root@docker ~]# vim dockerfile
[root@docker ~]# cat dockerfile
FROM centos:8

RUN rm -rf /etc/yum.repos.d/* && \
    curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo && \
    sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo && \
    yum clean all && \
    yum makecache && \
    yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel && \
    yum -y install wget && \
    wget https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.79/bin/apache-tomcat-9.0.79.tar.gz && \
    tar -xf apache-tomcat-9.0.79.tar.gz && \
    mv apache-tomcat-9.0.79 /usr/local/tomcat && \
    /usr/local/tomcat/bin/startup.sh
    
CMD ["/usr/local/tomcat/bin/catalina.sh","run"]
[root@docker ~]# docker build -t harbor.server/library/tomcat:v1.0 .

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

//上传到私有镜像仓库
[root@docker ~]# docker push harbor.server/library/tomcat:v1.0

部署webs主机

bash 复制代码

//安装docker，前面有教程

//配置连接私有镜像仓库
[root@webs ~]# vim /etc/docker/daemon.json 
[root@webs ~]# cat /etc/docker/daemon.json 
{
  "insecure-registries": ["harbor.server"]
}
[root@webs ~]# 

//重启docker服务
[root@webs ~]# systemctl daemon-reload 
[root@webs ~]# systemctl restart docker.service

企业业务代码项目发布流程

1.将代码上传到gitlab主机

这通常是代码开发人员的事情

如何在gitlab创建项目请阅读GitLab版本控制

bash 复制代码

//从公共代码仓库拉取需要的代码
[root@gitlab ~]# git clone 'https://gitee.com/forgotten/tomcat-java-demo.git'


//上传代码到本地代码仓库的操作
[root@gitlab ~]# git config --global user.name "root"
[root@gitlab ~]# git config --global user.email "[email protected]"
[root@gitlab ~]# git clone http://192.168.179.13/root/wanf.git
[root@gitlab ~]# mv tomcat-java-demo/* wanf/
mv: overwrite 'wanf/README.md'? y
[root@gitlab ~]# cd wanf/
[root@gitlab wanf]# ls
db  deploy.yaml  Dockerfile  jenkinsfile  LICENSE  pom.xml  README.md  src

[root@gitlab wanf]# 
[root@gitlab wanf]# git add *
[root@gitlab wanf]# git commit -m "test"
[root@gitlab wanf]# git push --set-upstream origin

[root@gitlab wanf]#

后期开发人员上传的新代码会自动更新在此

2.在Jenkins创建项目，并写流水线脚本，运行项目

Jenkins使用方法请阅读Jenkins部署与应用

Jenkins流水线脚本如下：

bash 复制代码

pipeline {
    agent any
    stages {
        stage("pull code"){
            steps {
                sh """
                    git clone http://192.168.179.13/root/wanf.git && mv /root/.jenkins/workspace/wanf/wanf /root/wanf
                """
            }
        }
        stage("pull images"){
            steps {
                sh """
                    docker pull harbor.server/library/tomcat:v1.0
                """
            }
        }
        stage("make .war pkgs"){
            steps {
                sh """
                    cd /root/wanf && mvn clean package -Dmaven.test.skip=true && mv /root/wanf/target/ly-simple-tomcat-0.0.1-SNAPSHOT.war /root/test.war
                """
            }
        }
        stage("vim dockerfile"){
            steps {
                sh """
                    echo "FROM harbor.server/library/tomcat:v1.0" >> /root/dockerfile && echo "RUN rm -rf /usr/local/tomcat/webapps/ROOT" >> /root/dockerfile && echo "COPY ./test.war /usr/local/tomcat/webapps/ROOT.war" >> /root/dockerfile && echo 'CMD ["/usr/local/tomcat/bin/catalina.sh","run"]' >> /root/dockerfile
                """
            }
        }
        stage("make new images"){
            steps {
                sh """
                    cd /root && docker build -t harbor.server/library/wanf:v0.1 .
                """
            }
        }
        stage("push images"){
            steps {
                sh """
                    docker login harbor.server -u admin -p 123456 && docker push harbor.server/library/wanf:v0.1
                """
            }
        }
        stage("webs pull and run"){
            steps {
                sh """
                    ssh webs "docker pull harbor.server/library/wanf:v0.1" && ssh webs "docker run -d --name test -p 80:8080 -it harbor.server/library/wanf:v0.1"
                """
            }
        }
    }
}

3.在webs服务器上测试

在浏览器访问webs服务器的IP地址
