Как совместить приложение ASP.NET Core и Redis?

Question

Я работаю с Docker и пытаюсь подключить Redis и веб-приложение.Это мой файл docker-compose:

version: '3.7'

services:  
  web:
    image: redistest:latest
    depends_on:
      - "redis_image"
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "9901:80"

  redis_image:
    image: redis
    container_name: cache
    ports:
      - "6379:6379"

Это мои ConnectionStrings:

"ConnectionStrings": {
    "redis": "localhost:6379,abortConnect=False"
  },

Dockerfile выглядит следующим образом:

FROM microsoft/dotnet:sdk AS build-env
WORKDIR /app
EXPOSE 80

COPY *.csproj ./
RUN dotnet restore RedisTest.csproj

COPY . ./
RUN dotnet publish RedisTest.csproj -c Release -o out

FROM microsoft/dotnet:aspnetcore-runtime
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT ["dotnet", "RedisTest.dll"]

Подключение к Redis при запуске.cs: ​​

services.AddDistributedRedisCache(option =>
{
    option.Configuration = Configuration.GetConnectionString("redis");
}); 

Для подключения к докеру я пишу в cmd следующие команды:

docker-compose build
docker-compose up

Эти команды работают хорошо, но после перехода на "localhost: 9901" я получаюследующие ошибки в консоли

web_1          | fail: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[1]
web_1          |       An unhandled exception has occurred while executing the request.

Как я могу исправить эту проблему?Я не знаю, как заставить приложение ASP.NET Core увидеть Redis в Docker.

Answer 1

Необходимо изменить 2 вещи:

1: файл Docker-compose должен быть обновлен и должен содержать ссылки для связи с контейнером.

version: '3.7'

services:  
  web:
    image: redistest:latest
    depends_on:
      - "redis_image"
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "9901:80"
    links:
      - "redis_image"

  redis_image:
    image: redis
    container_name: cache
    ports:
      - "6379:6379"

2: ConnectionStringsдолжно быть обновлено.Вместо localhost используйте имя службы redis_image, как показано ниже

"ConnectionStrings": {
    "redis": "redis_image:6379,abortConnect=False"
  },

Дайте мне знать результаты
