实践Kong for Kubernetes（K8S），kong最新2.1版本和kong-ingress-controller:0.9.1版本
先决条件
- Kubernetes集群：您可以使用Minikube或GKE集群。Kong与Kubernetes的所有发行版兼容。
- kubectl访问权限：您应该已经
kubectl安装并配置为与Kubernetes集群通信。
为Kubernetes安装Kong
使用以下安装方法之一安装Kong for Kubernetes：
YAML清单
要通过部署Kong kubectl，请使用：
kubectl apply -f https://bit.ly/kong-ingress-dbless
重要！这不是生产级部署。根据您的用例调整“参数”：
- 副本：确保您正在运行Kong的多个实例，以防止由于单个节点故障而造成的中断。
- 性能优化：调整Kong的内存设置，并根据使用情况定制部署。
- 负载均衡器：确保在Kong前面运行基于4层或TCP的均衡器。这使Kong可以提供TLS证书并与证书管理器集成。
helm部署
Kong有一个官方的Helm Chart。要将Kong部署到带有Helm的Kubernetes集群上，请使用：
$ helm repo add kong https://charts.konghq.com
$ helm repo update
# Helm 2
$ helm install kong/kong
# Helm 3
$ helm install kong/kong --generate-name --set ingressController.installCRDs=false
Kustomize
可以使用Kubernetes的kustomize声明性地修补Kong的Kubernetes清单。远程定制构建的一个示例是：
kustomize build github.com/kong/kubernetes-ingress-controller/deploy/manifests/base
在Kong的存储库中可以使用Kustomization 进行不同类型的部署。
使用托管的Kubernetes云产品
如果您正在使用云提供商将Kong安装在托管的Kubernetes产品上，例如Google Kubernetes Engine（GKE），Amazon EKS（EKS），Azure Kubernetes Service（AKS）等，请确保已设置Kubernetes群集在云提供程序上，并已kubectl在您的工作站上进行了配置。
一旦您配置了Kubernetes集群并配置了kubectl，任何云提供商的安装都将使用上述方法之一（YAML manifests，Helm Chart或Kustomize）来安装Kong。
每个云提供商在允许如何配置特定资源（例如负载均衡器，存储卷等）方面都有一些细微的不同。我们建议您参考其文档来调整这些设置。
关于Kong的数据库使用
如果您使用的是数据库，我们建议您在Kubernetes内部以内存模式（也称为无DB）运行Kong，因为所有配置都存储在Kubernetes控制面板中。此设置简化了Kong的操作，因此无需担心数据库的设置，备份，可用性，安全性等。如果您决定使用数据库，建议您在Kubernetes之外运行数据库。您可以从云提供商使用Amazon RDS之类的服务或类似的托管Postgres服务来自动执行数据库操作。
我们不建议在Kubernetes部署中将Kong与Cassandra一起使用，因为Kong的Cassandra使用所涵盖的功能是通过Kubernetes中的其他方式处理的。
采用yaml清单方式实践
- 通过浏览器打开官方下载地址https://bit.ly/kong-ingress-dbless，下载对应的yaml文件
wget https://raw.githubusercontent.com/Kong/kubernetes-ingress-controller/master/deploy/single/all-in-one-dbless.yaml
- 当前kong:2.1，kong-ingress-controller:0.9.1，修改service配置为NodePort，默认是LoadBalancer，整体配置文件如下：
[root@localhost kong-gateway]# cat all-in-one-dbless.yaml
