. net Core 5 Web Api AppSettings.在docker容器中找不到Json

Question

我正在为我的学校项目在。net Core 5做一个API。对于这个项目，我使用了一个模板，其中包含基础设施、领域、应用程序等多个项目。对于数据库，我使用MySQL，一切都在本地主机上工作得很好。现在我想要Dockerize这个项目，所以我将学习如何使用Docker。

我创建了以下两个文件:

FROM mcr.microsoft.com/dotnet/aspnet:5.0-focal AS base
WORKDIR /app
EXPOSE 5000
EXPOSE 5001
ENV ASPNETCORE_URLS=http://+:5000
ENV ASPNETCORE_ENVIRONMENT=Development
# Creates a non-root user with an explicit UID and adds permission to access the /app folder
# For more info, please refer to https://aka.ms/vscode-docker-dotnet-configure-containers
RUN adduser -u 5678 --disabled-password --gecos "" appuser && chown -R appuser /app
USER appuser
FROM mcr.microsoft.com/dotnet/sdk:5.0-focal AS build
WORKDIR /src
COPY ["HabitAPI.Api/HabitAPI.Api.csproj", "HabitAPI.Api/"]
COPY ["HabitAPI.Application/HabitAPI.Application.csproj", "HabitAPI.Application/"]
COPY ["HabitAPI.Domain/HabitAPI.Domain.csproj", "HabitAPI.Domain/"]
COPY ["HabitAPI.Infrastructure/HabitAPI.Infrastructure.csproj", "HabitAPI.Infrastructure/"]
COPY ["HabitAPI.Infrastructure.Shared/HabitAPI.Infrastructure.Shared.csproj", "HabitAPI.Infrastructure.Shared/"]
RUN dotnet restore "HabitAPI.Api/HabitAPI.Api.csproj"
COPY . .
WORKDIR "/src/HabitAPI.Api"
RUN dotnet build "HabitAPI.Api.csproj" -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "HabitAPI.Api.csproj" -c Release -o /app/publish
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "HabitAPI.Api.dll"]

:

# docker-compose up -d
# docker-compose down
version: "3.6"
services:
db:
image: mysql/mysql-server:5.7
restart: always
container_name: habitapi-db
environment:
- MYSQL_USER=root
- MYSQL_PASSWORD=user
- MYSQL_ROOT_PASSWORD=user
- MYSQL_DATABASE=habitapi_db
ports:
- "3306"
phpmyadmin:
image: phpmyadmin/phpmyadmin
container_name: habitapi-pma
ports:
- "81:80"
external_links:
- db:mysql
environment:
PMA_HOST: "db"
PMA_PORT: 3306
habitapi-api:
build:
context: .
dockerfile: HabitAPI.Api/Dockerfile
container_name: habitapi-api
environment:
- ASPNETCORE_ENVIRONMENT=Development
- ASPNETCORE_URLS=http://+:5000;
ports:
- 5000:5000
- 5001:5001
links:
- db
depends_on:
- db

当我执行以下命令时:

docker compose up——build

在api上得到以下错误:

habitapi-api    | Unhandled exception. System.IO.FileNotFoundException: The 
configuration file 'AppSettings.json' was not found and is not optional. The physical path is '/app/AppSettings.json'.

habitapi-api    |    at HabitAPI.Api.Program.<Main>(String[] args)

奇怪的是，当我打开Docker Desktop并进入cli并执行ls命令时，文件就在那里。会是什么呢?

replace "app/publish"与"app/"在docker文件
