一、构建docker镜像并测试
1、在node2上编辑dockerfile
[root@node02 opt]# cd xiaoniao/ [root@node02 xiaoniao]# ls 2000.png 21.js icon.png img index.html sound1.mp3 [root@node02 xiaoniao]# vim dockerfile [root@node02 xiaoniao]# vi .dockerignore [root@node02 xiaoniao]# cat dockerfile FROM 192.168.118.188:5000/nginx:1.13 ADD . /usr/share/nginx/html [root@node02 xiaoniao]# cat .dockerignore dockerfile
2、jenkins web页面配置

二、自动化构建docker镜像问题
1、自动化构建docker镜像版本问题
使用jenkins环境变量
BUILD_ID
查看可用变量
http://192.168.118.19:8080/env-vars.html/ BUILD_ID The current build ID, identical to BUILD_NUMBER for builds created in 1.597+, but a YYYY-MM-DD_hh-mm-ss timestamp for older builds

重点看版本:+ docker push 192.168.118.188:5000/xiaoniao:v9
构建版本查询
[root@master _manifests]# ls /opt/myregistry/docker/registry/v2/repositories/xiaoniao/_manifests/tags/ v1 v10 v9
2、防止误操作立即构建
配置截图
#!/bin/bash if [ $GIT_PREVIOUS_SUCCESSFUL_COMMIT == $GIT_COMMIT ];then echo "no change,skip build" exit 0 else docker build -t 192.168.118.18:5000/xiaoniao:v$BUILD_ID . docker push 192.168.118.18:5000/xiaoniao:v$BUILD_ID fi

三、k8s集群部署项目
1、部署项目
[root@master _manifests]# kubectl run xiaoniao --image=192.168.118.188:5000/xiaoniao:v1 --replicas=2 --record deployment "xiaoniao" created [root@master _manifests]# kubectl rollout history deployment xiaoniao deployments "xiaoniao" REVISION CHANGE-CAUSE 1 kubectl run xiaoniao --image=192.168.118.188:5000/xiaoniao:v1 --replicas=2 --record
2、设置对外访问
[root@master _manifests]# kubectl expose deployment xiaoniao --port=80 --type=NodePort service "xiaoniao" exposed [root@master _manifests]# kubectl get svc NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE glusterfs 10.254.122.179 <none> 49152/TCP 2d kubernetes 10.254.0.1 <none> 443/TCP 9d mysql 10.254.168.177 <none> 3306/TCP 5d myweb 10.254.202.136 <nodes> 8080:30008/TCP 5d readiness 10.254.199.105 <none> 80/TCP 3d xiaoniao 10.254.22.194 <nodes> 80:32392/TCP 9s
3、测试访问:
[root@master _manifests]# curl 192.168.118.19:32392|grep '小鸟' % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 3049 100 3049 0 0 707k 0 --:--:-- --:--:-- --:--:-- 992k <title>小鸟飞飞飞-文章库小游戏</title> "tTitle": "小鸟飞飞飞-文章库小游戏", document.title = "我玩小鸟飞飞飞过了"+t+"关!你能超过洒家我吗?";
4、测试截图
四、k8s 版本升级和回滚
1、版本更新
[root@master _manifests]# ls /opt/myregistry/docker/registry/v2/repositories/xiaoniao/_manifests/tags/ v1 v10 v13 v9 [root@master _manifests]# kubectl set image deploy xiaoniao xiaoniao=192.168.118.188:5000/xiaoniao:v13 deployment "xiaoniao" image updated

[root@master _manifests]# curl 192.168.118.19:32392|grep '小鸟' % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 3049 100 3049 0 0 706k 0 --:--:-- --:--:-- --:--:-- 992k <title>小鸟飞飞飞-文章库小游戏</title> "tTitle": "小鸟飞飞飞-文章库小游戏", document.title = "我玩小鸟飞飞飞过了"+t+"关!你能超过洒家我吗?";
2、回滚指定版本
[root@master _manifests]# kubectl rollout undo deployment xiaoniao --to-revision=1 deployment "xiaoniao" rolled back
[root@master _manifests]# curl 192.168.118.19:32392|grep '小鸟' % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 3049 100 3049 0 0 744k 0 --:--:-- --:--:-- --:--:-- 992k <title>小鸟飞飞飞-文章库小游戏</title> "tTitle": "小鸟飞飞飞-文章库小游戏", document.title = "我玩小鸟飞飞飞过了"+t+"关!你能超过洒家我吗?";
[root@master _manifests]# kubectl rollout undo deployment xiaoniao deployment "xiaoniao" rolled back
[root@master _manifests]# curl 192.168.118.19:32392|grep '小鸟' % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 3049 100 3049 0 0 849k 0 --:--:-- --:--:-- --:--:-- 992k <title>小鸟飞飞飞-文章库小游戏</title> "tTitle": "小鸟飞飞飞-文章库小游戏", document.title = "我玩小鸟飞飞飞过了"+t+"关!你能超过洒家我吗?";
3、回滚到上一个版本
[root@master _manifests]# kubectl rollout history deployment xiaoniao deployments "xiaoniao" REVISION CHANGE-CAUSE 1 kubectl run xiaoniao --image=192.168.118.188:5000/xiaoniao:v1 --replicas=2 --record 2 kubectl set image deploy xiaoniao xiaoniao=192.168.118.188:5000/xiaoniao:v13 3 kubectl set image deploy xiaoniao xiaoniao=192.168.118.188:5000/xiaoniao:v10 [root@master _manifests]# kubectl rollout history View rollout history pause Mark the provided resource as paused resume Resume a paused resource status Show the status of the rollout undo Undo a previous rollout [root@master _manifests]# kubectl rollout undo deployment xiaoniao --to-revision=1 deployment "xiaoniao" rolled back
