新建webapi项目
- 建项目时取消https支持，勾选docker支持，
TP request pipeline. //if (app.Environment.IsDevelopment()) { app.UseSwagger(); app.UseSwaggerUI(); }using Dapr; using Dapr.Client; using Microsoft.AspNetCore.Mvc; namespace backend.Controllers { [ApiController] [Route("[controller]")] public class WeatherForecastController : ControllerBase { private readonly DaprClient _daprClient; public WeatherForecastController(DaprClient daprClient) { _daprClient = daprClient; } [HttpGet(Name = "GetWeatherForecast")] public object Get() { return new { message = "Hello Dapr!" }; } [HttpPost(nameof(SaveStateValue))] public async Task SaveStateValue(StateModel stateModel) { await _daprClient.SaveStateAsync("statestore", stateModel.Key, stateModel.Value);//statestore } [HttpDelete(nameof(DeleteStateValue) + "/{stateKey}")] public async Task DeleteStateValue(string stateKey) { await _daprClient.DeleteStateAsync("statestore", stateKey); } [HttpGet("GetStateValue/{stateKey}")] public async Task<string> GetStateValue(string stateKey) { return await _daprClient.GetStateAsync<string>("statestore", stateKey); } [HttpGet(nameof(GetStateValueFromState) + "/{stateKey}")] public async Task<string> GetStateValueFromState([FromState("statestore", "stateKey")] StateEntry<string> stateEntry) { return await Task.FromResult(stateEntry.Value); } } }增加文件StateModel.csnamespace backend.Controllers { public class StateModel { public string Key { get; set; } public string Value { get; set; } } }
- Program.cs中注释下面语句，这样部署后才能访问Swagger
- 添加Dapr.Client与Dapr.AspNetCore两个nuget包
- 修改Program.cs文件，增加dapr sdk支持
- 修改WeatherForecastController.cs文件
dapr自托管部署
修改launchSettings.json文件，端口改成5002，如下图
dapr init
dapr run --app-id front --app-port 5002 dotnet run 访问http://localhost:5002/swagger/index.html
操作各个方法，都符合预期就对了
部署到k8s
docker build -t daprfrontend:v1 -f backend/Dockerfile .
dapr init -k
kubectl apply -f redis.yaml
kubectl apply -f statestore.yaml
kubectl apply -f dapr-front.yaml#redis.yaml 文件

我是nat到虚拟机
测试接口，如果都能正常设置状态，获取状态，删除状态就OK了
常用命令
docker build -t daprfrontend:v1 -f backend/Dockerfile .
::kubectl delete all --all
::dapr uninstall --all
::dapr init -k
kubectl apply -f namespace.yaml
kubectl apply -f dapr-config.yaml
kubectl apply -f zipkin.yaml
kubectl apply -f redis.yaml
kubectl apply -f statestore.yaml
::kubectl apply -f dapr-statestore-test.yaml
:: kubectl delete -f dapr-front.yaml
kubectl apply -f dapr-front.yaml
