# spring-cloud-kubernetes
> 本项目仅讨论 kubernetes 的落地实现，关于各项组件含义配置使用见 [ToQuery/example-kubernetes](https://github.com/ToQuery/example-kubernetes)
## 快速使用 Hello World 服务
```shell script
# 创建命名空间
kubectl apply -f https://raw.githubusercontent.com/ToQuery/example-spring-cloud-kubernetes/master/hello-world/k8s/example-spring-cloud-kubernetes-hello-world-ns.yaml
# 创建角色访问资源
kubectl apply -f https://raw.githubusercontent.com/ToQuery/example-spring-cloud-kubernetes/master/hello-world/k8s/example-spring-cloud-kubernetes-hello-world-rbac.yaml
# 创建服务
kubectl apply -f https://raw.githubusercontent.com/ToQuery/example-spring-cloud-kubernetes/master/hello-world/k8s/example-spring-cloud-kubernetes-hello-world-svc.yaml
# 创建访问入口
kubectl apply -f https://raw.githubusercontent.com/ToQuery/example-spring-cloud-kubernetes/master/hello-world/k8s/example-spring-cloud-kubernetes-hello-world-ingress.yaml
# 创建配置
kubectl apply -f https://raw.githubusercontent.com/ToQuery/example-spring-cloud-kubernetes/master/hello-world/k8s/example-spring-cloud-kubernetes-hello-world-cm.yml
```
等待服务部署完毕后（或通过命令行 `kubectl get pods -w`），查看服务的部署情况
```shell script
kubectl get services example-spring-cloud-kubernetes-hello-world
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
example-spring-cloud-kubernetes-hello-world ClusterIP 10.102.61.4 8080:31730/TCP 51m
```
这里有两种方式访问服务：
1. (推荐）通过 Ingress 访问
配置 hosts 文件(`/etc/hosts`)，添加访问域名：
```shell script
cat /etc/hosts
127.0.0.1 kubernetes-hello-world.toquery.com
```
- 访问 `http://kubernetes-hello-world.toquery.com` 即可 `Hello World`
- 访问 `http://kubernetes-hello-world.toquery.com/services` 可查看所有注册的服务
- 访问 `http://kubernetes-hello-world.toquery.com/services/{name}` 可查看 `name` 服务的信息
- 访问 `http://kubernetes-hello-world.toquery.com/configs/message` 获取项目配置信息，或k8s的config-map配置
2. 通过 PORT 端口，例如： http://localhost:31730
- 访问 `http://localhost:31730` 即可 `Hello World`
- 访问 `http://localhost:31730/services` 可查看所有注册的服务
- 访问 `http://localhost:31730/services/{name}` 可查看 `name` 服务的信息
- 访问 `http://localhost:31730/configs/message` 获取项目配置信息，或k8s的config-map配置
