jenkins自动化构建docker镜像并部署到k8s集群
一、集群规划
二、安装gitlab并上传代码
1. 下载安装包，并安装
[root@kub_node2 tools]# wget https://mirror.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-11.9.11-ce.0.el7.x86_64.rpm --2020-10-04 21:13:08-- https://mirror.tuna.tsinghua.edu.cn/gitlab-ce/yum/el7/gitlab-ce-11.9.11-ce.0.el7.x86_64.rpm Resolving mirror.tuna.tsinghua.edu.cn (mirror.tuna.tsinghua.edu.cn)... 101.6.8.193, 2402:f000:1:408:8100::1 Connecting to mirror.tuna.tsinghua.edu.cn (mirror.tuna.tsinghua.edu.cn)|101.6.8.193|:443... connected.

GitLab was unable to detect a valid hostname for your instance. Please configure a URL for your GitLab instance by setting `external_url` configuration in /etc/gitlab/gitlab.rb file. Then, you can start your GitLab instance by running the following command: sudo gitlab-ctl reconfigure For a comprehensive list of configuration options please see the Omnibus GitLab readme https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
2. 修改配置文件
[root@kub_node2 tools]# vim /etc/gitlab/gitlab.rb [root@kub_node2 tools]# sed -n 13p /etc/gitlab/gitlab.rb external_url 'http://192.168.0.208' [root@kub_node2 tools]# sed -n 1535p /etc/gitlab/gitlab.rb prometheus_monitoring['enable'] = false
3.启动gitlab
[root@kub_node2 tools]# gitlab-ctl reconfigure
4.访问gitlab，修改root密码，创建project
http://192.168.0.208
5.gitlab上传代码
[root@kub_node2 tools]# cd /opt [root@kub_node2 opt]# mkdir xiaoniao [root@kub_node2 opt]# cd xiaoniao/ [root@kub_node2 xiaoniao]# git config --global user.name "Administrator" [root@kub_node2 xiaoniao]# git config --global user.email "admin@example.com" [root@kub_node2 xiaoniao]# rz [root@kub_node2 xiaoniao]# ll total 92 -rw-r--r-- 1 root root 91014 Oct 4 21:48 xiaoniaofeifei.zip [root@kub_node2 xiaoniao]# unzip xiaoniaofeifei.zip Archive: xiaoniaofeifei.zip inflating: sound1.mp3 creating: img/ inflating: img/bg1.jpg inflating: img/bg2.jpg inflating: img/number1.png inflating: img/number2.png inflating: img/s1.png inflating: img/s2.png inflating: 21.js inflating: 2000.png inflating: icon.png inflating: index.html [root@kub_node2 xiaoniao]# ll total 236 -rw-r--r-- 1 root root 15329 Aug 2 2014 2000.png -rw-r--r-- 1 root root 51562 Aug 2 2014 21.js -rw-r--r-- 1 root root 254 Aug 2 2014 icon.png drwxr-xr-x 2 root root 4096 Aug 8 2014 img -rw-r--r-- 1 root root 3049 Aug 2 2014 index.html -rw-r--r-- 1 root root 63008 Aug 2 2014 sound1.mp3 -rw-r--r-- 1 root root 91014 Oct 4 21:48 xiaoniaofeifei.zip [root@kub_node2 xiaoniao]# rm -rf xiaoniaofeifei.zip [root@kub_node2 xiaoniao]# ls 2000.png 21.js icon.png img index.html sound1.mp3

三、安装jenkins并拉取代码
1. 安装jenkins
[root@kub_node1 ~]# mkdir -p /server/tools [root@kub_node1 ~]# cd /server/tools/

4. 构建docker镜像并测试
1）编写dockerfile
[root@kub_node2 xiaoniao]# vim dockerfile [root@kub_node2 xiaoniao]# cat dockerfile FROM 192.168.0.212:5000/nginx:1.15 ADD . /usr/share/nginx/html
2）添加docker build构建时不add的文件
[root@kub_node2 xiaoniao]# vim .dockerignore
[root@kub_node2 xiaoniao]# cat .dockerignore
dockerfile
3）创建docker镜像，并启动容器
[root@kub_node2 xiaoniao]# docker build -t xiaoniao:v1 .

5. jenkins自动化构建docker镜像
1）推送当前代码到gitlab仓库
[root@kub_node2 xiaoniao]# git add . [root@kub_node2 xiaoniao]# git commit -m 'first update' [master a76dbc4] first update 2 files changed, 3 insertions(+) create mode 100644 .dockerignore create mode 100644 dockerfile [root@kub_node2 xiaoniao]# git push -u origin master Username for 'http://192.168.0.208': root Password for 'http://root@192.168.0.208': Counting objects: 5, done. Delta compression using up to 2 threads. Compressing objects: 100% (3/3), done. Writing objects: 100% (4/4), 384 bytes | 0 bytes/s, done. Total 4 (delta 1), reused 0 (delta 0) To http://192.168.0.208/root/xiaoniao.git 9568708..a76dbc4 master -> master Branch master set up to track remote branch master from origin.
2）修改jenkins配置
3）构建镜像
点击立即构建，查看控制台输出
私有仓库查看镜像
[root@kub_master ~]# ls /opt/myregistry/docker/registry/v2/repositories/ busybox heapster_grafana kubernetes-dashboard-amd64 nginx tomcat-app xiaoniao heapster heapster_influxdb mysql pod-infrastructure wordpress [root@kub_master ~]# ls /opt/myregistry/docker/registry/v2/repositories/xiaoniao/ _layers _manifests _uploads [root@kub_master ~]# ls /opt/myregistry/docker/registry/v2/repositories/xiaoniao/_manifests/ revisions tags [root@kub_master ~]# ls /opt/myregistry/docker/registry/v2/repositories/xiaoniao/_manifests/tags/ v1
6.自动化构建docker镜像解决版本问题
注：使用jenkins环境变量 BUILD_ID，此参数为构建次数
1）修改jenkins配置
2）构建
[root@kub_master ~]# ls /opt/myregistry/docker/registry/v2/repositories/xiaoniao/_manifests/tags/
v1 v4
版本已更新，版本号为构建次数
7. 防止误操作立即构建
1）修改jenkins配置
#!/bin/bash if [ $GIT_PREVIOUS_SUCCESSFUL_COMMIT == $GIT_COMMIT ];then echo "no change，skip build" exit 0 else docker build -t 192.168.0.212:5000/xiaoniao:v$BUILD_ID . docker push 192.168.0.212:5000/xiaoniao:v$BUILD_ID fi
2）构建，查看控制台输出
3）修改站点目录文件，并上传至远程仓库
[root@kub_node2 xiaoniao]# vim index.html [root@kub_node2 xiaoniao]# cat index.html |grep dokcer <title>小鸟飞飞飞-dokcer image 小游戏</title> [root@kub_node2 xiaoniao]# git add . [root@kub_node2 xiaoniao]# git commit -m 'second update' [master 8220d7d] second update 1 file changed, 1 insertion(+), 1 deletion(-) [root@kub_node2 xiaoniao]# git push -u origin master Username for 'http://192.168.0.208': root Password for 'http://root@192.168.0.208': Counting objects: 5, done. Delta compression using up to 2 threads. Compressing objects: 100% (3/3), done. Writing objects: 100% (3/3), 304 bytes | 0 bytes/s, done. Total 3 (delta 2), reused 0 (delta 0) To http://192.168.0.208/root/xiaoniao.git a76dbc4..8220d7d master -> master Branch master set up to track remote branch master from origin.
4）jenkins重新构建
[root@kub_master ~]# ls /opt/myregistry/docker/registry/v2/repositories/xiaoniao/_manifests/tags/
v1 v4 v6
8. k8s集群部署项目
