.NET 8 インプロセスの Azure Functions を 分離ワーカーに移行する検証をしてみた
.NET 6 インプロセスの Azure Functions は、.NET 8 のインプロセスに移行しました。
次は、.NET 8 インプロセスから .NET 8 分離ワーカーに移行して、次の LTS バージョンとなる .NET 10 分離ワーカーの移行に備えておきたいと思います。
移行元となる検証用の .NET 8 インプロセスを作成
bash
func init mnrdn8in --target-framework net8.0 --worker-runtime dotnet
cd mnrdn8in
func new --name Sample --template HttpTrigger
func start
curl http://localhost:7071/api/Sample
.NET 8 インプロセスの検証用アプリ
Sample.cs
using System;
using System.IO;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
namespace mnrdn8in
{
public static class Sample
{
[FunctionName("Sample")]
public static async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
string name = req.Query["name"];
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
name = name ?? data?.name;
string responseMessage = string.IsNullOrEmpty(name)
? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
: $"Hello, {name}. This HTTP triggered function executed successfully.";
return new OkObjectResult(responseMessage);
}
}
}
移行先となる .NET 8 分離ワーカーを作成
bash
cd ..
func init mnrdn8iso --target-framework net8.0 --worker-runtime dotnet-isolated
cd mnrdn8iso
func new --name Sample --template HttpTrigger
func start
curl http://localhost:7071/api/Sample
Sample.cs を分離ワーカー用に最低限の修正
Sample.cs
using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.Logging;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Newtonsoft.Json;
namespace mnrdn8iso
{
public class Sample
{
private readonly ILogger<Sample> log;
public Sample(ILogger<Sample> logger)
{
log = logger;
}
[Function("Sample")]
public async Task<IActionResult> Run([HttpTrigger(AuthorizationLevel.Function, "get", "post")] HttpRequest req)
{
log.LogInformation("C# HTTP trigger function processed a request.");
string? name = req.Query["name"];
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic? data = JsonConvert.DeserializeObject(requestBody);
name = name ?? data?.name;
string responseMessage = string.IsNullOrEmpty(name)
? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
: $"Hello, {name}. This HTTP triggered function executed successfully.";
return new OkObjectResult(responseMessage);
}
}
}
動作確認
bash
$ func start
