Cloud相关内容，简化部分代码 6 | * 修改程序配置，适应k8s容器环境 7 | * 修改Docker打包相关配置，将镜像上传至阿里云的私有镜像 8 | * 增加用于本地minikube和阿里云k8s的部署文件 9 | 10 | 执行命令打包： 11 | ``` 12 | mvn clean package docker:build -Dmaven.test.skip 13 | ``` 14 | 15 | 在minikube中执行部署命令： 16 | ``` 17 | kubectl create -f takeout-minikube.yml 18 | ``` 19 | 20 | 部署到阿里云（需要事先在k8s上配置私有镜像的secret）： 21 | ``` 22 | kubectl create -f takeout-aliyun.yml 23 | ``` 24 | 25 | 在阿里云上如果部署了Istio，先设置自动注入SideCar： 26 | 27 | ``` 28 | kubectl label namespace default istio-injection=enabled 29 | ``` 30 | 31 | 在`istio`目录中有一些Istio的演示，先运行`kubectl create -f istio-destination.yml`创建Destination，随后再运行其他的Yaml。 32 | 33 | 可以用下面的命令开启Grafana，观察服务的调用情况： 34 | ``` 35 | kubectl -n istio-system port-forward $(kubectl -n istio-system get pod -l app=grafana -o jsonpath='{.items[0].metadata.name}') 3000:3000 & 36 | ``` 37 | -------------------------------------------------------------------------------- /section-12/customer-service/.gitignore:
