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.server192.168.179.13本地代码仓库gitlab-cecentos8
jenkins.server192.168.179.14编译代码、打包镜像、项目发布jenkins、docker、git、mavencentos8
harbor.server192.168.179.15本地容器镜像仓库(存储镜像)harbor、docker-compose、dockercentos8
docker192.168.179.16制作镜像、上传镜像dockercentos8
webs192.168.179.10测试环境( 项目发布在此主机)dockercentos8

基础配置

1.所有主机永久关闭防火墙和selinux
//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

//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.reposed -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.rpmsed -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

//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 lvm2yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.reposed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repoyum makecacheyum -y install docker-cesystemctl 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

//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

//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

2.配置gitlab
//修改 /etc/gitlab/gitlab.rb 的第32行、1011行、1115行
[root@gitlab ~]# vim /etc/gitlab/gitlab.rb 
##! https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instancedata-data-retrieval.html
external_url 'http://192.168.179.13'   //改成自己主机的域名或ip## Roles for multi-instance GitLab
(省略)
# gitlab_workhorse['listen_addr'] = "/var/opt/gitlab/gitlab-workhorse/sockets/socket"gitlab_workhorse['auth_backend'] = "http://localhost:8080"   //取消注释##! Enable Redis keywatcher, if this setting is not present it defaults to true
(省略)
# puma['listen'] = '127.0.0.1'puma['port'] = 8080     //取消注释
# puma['socket'] = '/var/opt/gitlab/gitlab-rails/sockets/gitlab.socket'
(省略)//重载配置文件
[root@gitlab ~]# gitlab-ctl reconfigure

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

//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

[root@jenkins local]# 
2.安装jenkins
//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 javaThere 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

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

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

建议直接安装全部插件

在这里插入图片描述

额外安装ssh、maven integration插件

4.安装git、maven、docker
//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
[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

//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
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):

部署docker主机

1.安装docker服务
//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
//制作tomcat镜像,并上传到harbor-server主机
[root@docker ~]# vim dockerfile
[root@docker ~]# cat dockerfile
FROM centos:8RUN 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.shCMD ["/usr/local/tomcat/bin/catalina.sh","run"]
[root@docker ~]# docker build -t harbor.server/library/tomcat:v1.0 .[root@docker ~]# docker images

部署webs主机

//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

//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 "12345678@qq.com"
[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
Username for 'http://192.168.179.13': root
Password for 'http://root@192.168.179.13': 
Enumerating objects: 849, done.

Branch 'main' set up to track remote branch 'main' from '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:

pipeline {agent anystages {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""""}}}
}
