要在AKS中使用Ocelot API网关,可以按照以下步骤进行操作:
ocelot.json的文件,其中定义了API网关的路由配置。下面是一个示例配置文件:{
"Routes": [
{
"DownstreamPathTemplate": "/api/users",
"DownstreamScheme": "http",
"DownstreamHostAndPorts": [
{
"Host": "users-service",
"Port": 80
}
],
"UpstreamPathTemplate": "/users",
"UpstreamHttpMethod": [ "GET" ]
},
{
"DownstreamPathTemplate": "/api/products",
"DownstreamScheme": "http",
"DownstreamHostAndPorts": [
{
"Host": "products-service",
"Port": 80
}
],
"UpstreamPathTemplate": "/products",
"UpstreamHttpMethod": [ "GET", "POST" ]
}
]
}
在这个示例配置中,定义了两个路由:/users和/products,它们分别转发到了users-service和products-service。
FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build-env
WORKDIR /app
COPY . ./
RUN dotnet restore
RUN dotnet publish -c Release -o out
FROM mcr.microsoft.com/dotnet/aspnet:5.0
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "APIGateway.dll"]
kubectl apply -f ocelot-deployment.yaml
其中,ocelot-deployment.yaml是一个Kubernetes部署文件,示例如下:
apiVersion: apps/v1
kind: Deployment
metadata:
name: ocelot-gateway
labels:
app: ocelot-gateway
spec:
replicas: 1
selector:
matchLabels:
app: ocelot-gateway
template:
metadata:
labels:
app: ocelot-gateway
spec:
containers:
- name: ocelot
image: /ocelot-gateway:latest
ports:
- containerPort: 80
将替换为你的Docker镜像仓库地址。
kubectl apply -f ocelot-service.yaml
ocelot-service.yaml是一个Kubernetes服务配置文件,示例如下:
apiVersion: v1
kind: Service
metadata:
name: ocelot-service
spec:
selector:
app: ocelot-gateway
ports:
- protocol: TCP
port: 80
targetPort: 80
type: LoadBalancer
完成以上步骤后,就可以通过访问API网关的域名来访问后端服务了。例如,使用http://来访问users-service的API。
