1.rs控制器

1.作用

可以实现Pod的副本控制。相比rc资源，其功能性更强且更加轻量级。

2.案例1-rs实现类似rc的功能

[root@master231 rs]# cat 01-rs-xiuxian-matchLabels.yaml 
apiVersion: apps/v1
kind: ReplicaSet
metadata:
  name: rs-xiuxian
spec:
  # 指定Pod的副本数量
  replicas: 3
  # 定义如何关联Pod
  selector:
    # 基于标签关联Pod
    matchLabels:
      apps: xiuxian
  # 定义Pod的模板
  template:
    metadata:
      labels:
        apps: xiuxian
        version: v1
    spec:
       containers:
       - name: c1
         image: registry.cn-hangzhou.aliyuncs.com/yinzhengjie-k8s/apps:v1
[root@master231 rs]#

3.案例2-rs实现优于rc的功能

	3.1 准备测试环境

[root@master231 ~]# kubectl run xiuxian01 --image=registry.cn-hangzhou.aliyuncs.com/yinzhengjie-k8s/apps:v1
pod/xiuxian01 created
[root@master231 ~]#
[root@master231 ~]# kubectl run xiuxian02 --image=registry.cn-hangzhou.aliyuncs.com/yinzhengjie-k8s/apps:v2
pod/xiuxian02 created
[root@master231 ~]#
[root@master231 ~]# kubectl run xiuxian03 --image=registry.cn-hangzhou.aliyuncs.com/yinzhengjie-k8s/apps:v3
pod/xiuxian03 created
[root@master231 ~]#
[root@master231 ~]#
[root@master231 ~]# kubectl label pod xiuxian01 apps=v1
pod/xiuxian01 labeled
[root@master231 ~]#
[root@master231 ~]# kubectl label pod xiuxian02 apps=v2
pod/xiuxian02 labeled
[root@master231 ~]#
[root@master231 ~]# kubectl label pod xiuxian03 apps=v3
pod/xiuxian03 labeled
[root@master231 ~]#
[root@master231 ~]# kubectl get pods --show-labels
NAME READY STATUS RESTARTS AGE LABELS
xiuxian01 1/1 Running 0 75s apps=v1,run=xiuxian01
xiuxian02 1/1 Running 0 69s apps=v2,run=xiuxian02
xiuxian03 1/1 Running 0 63s apps=v3,run=xiuxian03
[root@master231 ~]#
[root@master231 ~]# kubectl run xiuxian04 --image=registry.cn-hangzhou.aliyuncs.com/yinzhengjie-k8s/apps:v2
pod/xiuxian04 created
[root@master231 ~]#
[root@master231 ~]# kubectl label pod xiuxian04 apps=v4
pod/xiuxian04 labeled
[root@master231 ~]#
[root@master231 ~]# kubectl get pods --show-labels
NAME READY STATUS RESTARTS AGE LABELS
xiuxian01 1/1 Running 0 6m23s apps=v1,run=xiuxian01

xiuxian04 1/1 Running 0 28s apps=v4,run=xiuxian04
[root@master231 ~]#

		3.2 创建rs资源

[root@master231 rs]# cat 02-rs-xiuxian-matchExpressions.yaml
apiVersion: apps/v1
kind: ReplicaSet
metadata:
name: rs-xiuxian-matchexpressions
spec:

指定Pod的副本数量

replicas: 5

定义如何关联Pod

selector:
# 基于标签表达式关联Pod
matchExpressions:
# 代表的是标签的key
- key: apps
# 代表的是标签的value
values:
- v1
- v2
- v3
# 指定key和value之间的关系: In, NotIn, Exists and DoesNotExist
# In:
# key的值必须在value的列表之中。
# NotIn:
# 和In相反。
# Exists:
# 只要存在key即可，value任意，因此可以省略value字段。
# DoesNotExist:
# 不存在指定的key，和Exists相反，因此可以省略value字段。
operator: In

定义Pod的模板

template:
metadata:
labels:
apps: v1
school: oldboyedu
class: linux92
spec:
containers:
- name: c1
image: registry.cn-hangzhou.aliyuncs.com/yinzhengjie-k8s/apps:v1
[root@master231 rs]#
[root@master231 rs]# kubectl apply -f 02-rs-xiuxian-matchExpressions.yaml
replicaset.apps/rs-xiuxian-matchexpressions created
[root@master231 rs]#
[root@master231 rs]# kubectl get pods --show-labels
NAME READY STATUS RESTARTS AGE LABELS
rs-xiuxian-matchexpressions-6rgx2 1/1 Running 0 16s apps=v1,class=linux92,school=oldboyedu
rs-xiuxian-matchexpressions-md6jh 1/1 Running 0 16s apps=v1,class=linux92,school=oldboyedu
xiuxian01 1/1 Running 0 8m6s apps=v1,run=xiuxian01
xiuxian02 1/1 Running 0 8m apps=v2,run=xiuxian02
xiuxian03 1/1 Running 0 7m54s apps=v3,run=xiuxian03
xiuxian04 1/1 Running 0 2m11s apps=v4,run=xiuxian04
[root@master231 rs]#

  • deploy控制器
    1.作用
    用于部署服务，底层基于rs控制来控制Pod副本数量，并不会直接控制Pod。

相比于rc和rs而言， deploy支持声明式更新。

2.案例1-基于matchLabels匹配

[root@master231 deploy]# cat 01-deploy-xiuxian-matchLabels.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: deloy-xiuxian
spec:

2.案例2-基于matchLabels匹配

hint:
hint: git config --global init.defaultBranch
hint:
hint: Names commonly chosen instead of 'master' are 'main', 'trunk' and
hint: 'development'. The just-created branch can be renamed via this command:

2.访问测试

http://10.0.0.233:30080/

3.Jenkins更新K8S应用
	3.1 下载kubect的详细步骤

https://www.cnblogs.com/yinzhengjie/p/17981419#31-下载k8s二进制软件版

svip:
[root@jenkins211 ~]# wget http://192.168.16.253/Linux92/Kubernetes/day19-/softwares/jenkins/kubectl-1.23.17

	3.2 将kubectl放到PATH环境变量

[root@jenkins211 ~]# mv kubectl-1.23.17 /usr/local/sbin/kubectl
[root@jenkins211 ~]#
[root@jenkins211 ~]# chmod +x /usr/local/sbin/kubectl

	3.3 拷贝master节点的证书

[root@jenkins211 ~]# mkdir -pv ~/.kube/
[root@jenkins211 ~]#
[root@jenkins211 ~]# scp 10.0.0.231:/root/.kube/config ~/.kube/

	3.4 修改Jenkins脚本内容

docker image build -t harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:v3 .
docker push harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:v3
kubectl -n yiliao set image deploy deploy-yiliao yiliao=harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:v3

	3.5 测试验证

略。

  • Jenkins自定义文本参数进行版本构建
    1.添加文本参数变量
    略，见视频。

      2.脚本内容

docker image build -t harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:$version .
docker push harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:$version
kubectl -n yiliao set image deploy deploy-yiliao yiliao=harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:$version

  • Jenkins自定义选项参数进行版本构建
    1.添加选项参数变量
    略，见视频。

      2.脚本内容

docker image build -t harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:$tag .
docker push harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:$tag
kubectl -n yiliao set image deploy deploy-yiliao yiliao=harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:$tag

  • Jenkins基于git参数化构建
    1.添加git参数变量
    注意选择分支，参数类型是"修订"，可以基于"标签"，前提是你推过标签。

    2.脚本内容
    docker image build -t harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:$release .
    docker push harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:$release
    kubectl -n yiliao set image deploy deploy-yiliao yiliao=harbor.oldboyedu.com/oldboyedu-jenkins/yiliao:$release

  • Jenkins实现回滚
    略。

  • 今日内容回顾:

    • rs和rc的区别 *

    • deploy控制器 ****

      • 1.底层调用的是rs;
      • 2.支持声明式更新;
      • 3.默认有滚动更新策略;

    • Jenkins和K8S集成实现CI/CD *****

      • Jenkins的环境部署
      • 插件导入
      • 推送代码到gitee
      • Jenkins拉取代码编译推送到habor仓库
      • Jenkins更新K8S应用
      • Jenkins回滚

    • 镜像拉取策略：**
      Always
      IfNotPresent
      Never

周末作业:
- 完成课堂的所有练习并整理思维导图;
- 将Jenkins实现邮件，钉钉，企业微信告警功能，可以集成sonerQube，maven，...进行集成;

扩展:
- 1.使用pipeline语法改写自由风格的代码;
- 2.在网上找一个开发代码再跑一遍咱们的环境;
