#### 1 docker启动

```bash
docker stop $(docker ps -q) & docker rm $(docker ps -aq) #停用并删除全部容器
docker rmi $(docker images | grep "^<none>" | awk "{print $3}") #删除镜像

#build镜像
docker build -t msaservice.v06282024 -f
/elevenopen/0628/project/Zhaoxi.MicroService.ServiceInstance/Dockerfile

#### 4 各种操作

```bash
yml拷贝到241--elevenopen--0628
kubectl apply -f /elevenopen/0628/client.yaml

curl:
http://192.168.3.241:32200/Api/Test/index
http://192.168.3.241:32200/Api/Users/All

kubectl scale Deployment zhaoxinet6pre5msa-client-deployment --replicas=5 -n zhaoxinet6pre5msa

kubectl set image deploy zhaoxinet6pre5msa-client-deployment namezhaoxinet6pre5msa-client-pod=192.168.3.254:9999/zhaoxims/zhaoxinet6pre3msa:V202106280424 -n zhaoxinet6pre5msa
```

### 课堂脚本0629

#### 1 基础流程演示

```bash
kubectl apply -f /elevenopen/0415/client.yaml

curl http://192.168.3.241:32200/Api/Test/index

# 快速伸缩
kubectl scale Deployment zhaoxinet6pre5msa-client-deployment --replicas=5 -n zhaoxinet6pre5msa
kubectl scale Deployment zhaoxinet6pre5msa-client-deployment --replicas=2 -n zhaoxinet6pre5msa

失效转移---删除Pod---关闭docker

# 回滚&滚动发布
kubectl set image deploy zhaoxinet6pre5msa-client-deployment namezhaoxinet6pre5msa-client-pod=192.168.3.254:9999/zhaoxims/zhaoxinet6pre5msa:V202104151004 -n zhaoxinet6pre5msa
```

#### 2 流量自适应

```bash
# 删除指数收集deployment--命名空间kube-system--名字metrics
kubectl delete -n kube-system deployment metrics-server

# 创建HPA，安装components.yaml：
kubectl apply -f /elevenopen/0415/components.yaml  

# 给应用设置个资源限制380M内存 cpu限制
       resources:
           requests:
             cpu: 200m
             memory: 380Mi
           limits:
             cpu: 200m
             memory: 380Mi
            
# 重新创建：
kubectl apply -f /elevenopen/0415/client.yaml
kubectl apply -f /elevenopen/0415/client-hpa.yaml

# master查看
kubectl get pods -l app=label-zhaoxinet6pre5msa-client-pod -n zhaoxinet6pre5msa -w
#增加内存使用
http://192.168.3.241:32200/Api/Test/GC?id=1
```

#### 3 滚动发布

```bash
删除指数收集

# 准备新的images---默认滚动发布,重新创建(修改镜像名称)：
kubectl apply -f /elevenopen/0415/client.yaml
http://192.168.3.241:32200/Api/Test/Index

kubectl set image deploy zhaoxinet6pre5msa-client-deployment namezhaoxinet6pre5msa-client-pod=192.168.3.254:9999/zhaoxims/zhaoxinet6pre5msa:V202104152038 -n zhaoxinet6pre5msa

kubectl set image deploy zhaoxinet6pre5msa-client-deployment namezhaoxinet6pre5msa-client-pod=192.168.3.254:9999/zhaoxims/zhaoxinet6pre5msa:V202104151004 -n zhaoxinet6pre5msa

# 新窗口监控pod变化---可以看到滚动效果
kubectl get pods -l app=label-zhaoxinet6msa-client-pod -n zhaoxinet6msa -w
```

#### 4 灰度(金丝雀)发布

```bash
灰度发布，从V2到V3--动态换镜像---
# 先扩容一下：
kubectl scale Deployment zhaoxinet6pre5msa-client-deployment --replicas=5 -n zhaoxinet6pre5msa

kubectl set image deploy zhaoxinet6pre5msa-client-deployment namezhaoxinet6pre5msa-client-pod=192.168.3.254:9999/zhaoxims/zhaoxinet6pre5msa:V202104151004 -n zhaoxinet6pre5msa && kubectl rollout pause
deploy zhaoxinet6pre5msa-client-deployment -n zhaoxinet6pre5msa

# 查看更新情况(新增加一个资源，但是没执行。是因为pause暂停命令，所以发布一个，这样形成了金丝雀发布，这个金丝雀就是让真实用户验证的)
kubectl get pods -l app=label-zhaoxinet6pre5msa-client-pod -n zhaoxinet6pre5msa -w
# 那个金丝雀没问题，继续发布全部内容
kubectl rollout resume deploy zhaoxinet6pre5msa-client-deployment -n zhaoxinet6pre5msa
# 回滚：看历史版本
kubectl rollout history deploy zhaoxinet6pre5msa-client-deployment -n zhaoxinet6pre5msa
# 回滚到第0版(默认回滚上一版，可以通过 --to-revision指定版本)
kubectl rollout undo deploy zhaoxinet6pre5msa-client-deployment -n zhaoxinet6pre5msa --to-revision=4
```
