Docker Compose在复制时失败

我正在尝试设置docker compose部署，但其中一个项目中的副本存在问题。我尝试过几次改变路线，但都没有任何运气。我继续得到以下问题：

ERROR: Service 'cryptoappapi' failed to build : COPY failed: file not found in 
build context or excluded by .dockerignore: stat 
CryptoApp.Api/CryptoApp.Api.csproj: file does not exist

这是我的布局

这是我的docker文件是标准的：

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY ["CryptoApp.Api/CryptoApp.Api.csproj", "CryptoApp.Api/"]
RUN dotnet restore "CryptoApp.Api/CryptoApp.Api.csproj"
COPY . .
WORKDIR "/src/CryptoApp.Api"
RUN dotnet build "CryptoApp.Api.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "CryptoApp.Api.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "CryptoApp.Api.dll"]

这是我的docker compose：

services:
  # First the AspNet Core app
  cryptoappapi:
    ## Get the image to use and set the container name
    image: cryptoappapi:latest
    container_name: cryptoappapi

    # State a dependancy on Redis working
    depends_on:
      - "redis_image"
      - "postgres_image"

    # Location of the Dockerfile
    build:
      context: ./CryptoApp.Api
      dockerfile: Dockerfile

    # Set access ports for localhost on the left
    ports:
      - "80:5000"
      - "443:5001"

    # Configure a link to Redis
    links:
      - "redis_image"
      - "postgres_image"

    # The Application needs a connection string for Redis, this just needs to be the Redis Service name as defined below
    # Pass it in as an Environmental Variable
    environment:
      - RedisConnection=redis_image
      - DB_CONNECTION_STRING="host=postgres_image;port=5432;database=xx;username=xxx;password=xxx"
    
    # Set them all to the same network
    networks:
      - dockerapi-dev  

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY ["CryptoApp.Api.csproj", "CryptoApp.Api/"]
RUN dotnet restore "CryptoApp.Api/CryptoApp.Api.csproj"

在docker compose文件中，

build

可以指定为包含生成上下文路径的字符串，也可以指定为具有在

context

下指定的路径的对象，还可以选择

Dockerfile

如果设置了上下文，则该上下文将发送到Docker守护进程，并从指定的目录合成生成的映像

另外，将csproj复制到docker时，不需要包含该目录名 如果不想更改docker文件，可以编辑docker compose文件，将上下文更改为当前目录，并设置完整的docker文件目录

services:
  # First the AspNet Core app
  cryptoappapi:
    ## Get the image to use and set the container name
    image: cryptoappapi:latest
    container_name: cryptoappapi

    # State a dependancy on Redis working
    depends_on:
      - "redis_image"
      - "postgres_image"

    # Location of the Dockerfile
    build:
      context: .
      dockerfile: /CryptoApp.Api/Dockerfile

...

如果您不想更改docker compose，也可以通过这种方式更改docker文件：

services:
  # First the AspNet Core app
  cryptoappapi:
    ## Get the image to use and set the container name
    image: cryptoappapi:latest
    container_name: cryptoappapi

    # State a dependancy on Redis working
    depends_on:
      - "redis_image"
      - "postgres_image"

    # Location of the Dockerfile
    build:
      context: ./CryptoApp.Api
      dockerfile: Dockerfile

    # Set access ports for localhost on the left
    ports:
      - "80:5000"
      - "443:5001"

    # Configure a link to Redis
    links:
      - "redis_image"
      - "postgres_image"

    # The Application needs a connection string for Redis, this just needs to be the Redis Service name as defined below
    # Pass it in as an Environmental Variable
    environment:
      - RedisConnection=redis_image
      - DB_CONNECTION_STRING="host=postgres_image;port=5432;database=xx;username=xxx;password=xxx"
    
    # Set them all to the same network
    networks:
      - dockerapi-dev  

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY ["CryptoApp.Api.csproj", "CryptoApp.Api/"]
RUN dotnet restore "CryptoApp.Api/CryptoApp.Api.csproj"

您可以在物理级别共享文件夹结构吗？如果您的

构建：{context:}

是

CryptoApp.Api

目录，则在

复制

时不需要同时包含该目录名；只需

将./CryptoApp.Api.csproj

复制到映像树中。@DavidMaze因此，如果我删除，我会得到下一个错误服务“cryptoapppi”无法生成：命令“/bin/sh-c dotnet build”CryptoApp.Api.csproj”-c Release-o/app/build'返回非零代码：1此CSC:error CS5001:程序不包含适合入口点的静态“Main”方法[/src/CryptoApp.Api/CryptoApp.Api.csproj]已添加副本。在跑步之前，现在很开心
