I am trying to deploy ASPNETZERO to Digital Ocean but I am getting an error. Here is the docker file on the host folder: #See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.

FROM mcr.microsoft.com/dotnet/aspnet:7.0 AS base WORKDIR /app EXPOSE 80 EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build WORKDIR /src COPY ["src/WebPortal.Web.Host/WebPortal.Web.Host.csproj", "src/WebPortal.Web.Host/"] COPY ["src/WebPortal.Web.Core/WebPortal.Web.Core.csproj", "src/WebPortal.Web.Core/"] COPY ["src/WebPortal.Application/WebPortal.Application.csproj", "src/WebPortal.Application/"] COPY ["src/WebPortal.Application.Shared/WebPortal.Application.Shared.csproj", "src/WebPortal.Application.Shared/"] COPY ["src/WebPortal.Core.Shared/WebPortal.Core.Shared.csproj", "src/WebPortal.Core.Shared/"] COPY ["src/WebPortal.Core/WebPortal.Core.csproj", "src/WebPortal.Core/"] COPY ["src/WebPortal.EntityFrameworkCore/WebPortal.EntityFrameworkCore.csproj", "src/WebPortal.EntityFrameworkCore/"] COPY ["src/WebPortal.GraphQL/WebPortal.GraphQL.csproj", "src/WebPortal.GraphQL/"] RUN dotnet restore "src/WebPortal.Web.Host/WebPortal.Web.Host.csproj" COPY . . WORKDIR "/src/src/WebPortal.Web.Host" RUN dotnet build "WebPortal.Web.Host.csproj" -c Release -o /app/build

FROM build AS publish RUN dotnet publish "WebPortal.Web.Host.csproj" -c Release -o /app/publish

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

Below is the deployment file

    Hi mmorales

    1- Ensure that the paths in the COPY commands match the actual structure of your repository. For instance, if the WebPortal.Web.Host.csproj file is actually located in /src/WebPortal.Web.Host/ relative to your repository root, your Dockerfile's COPY command should correctly reflect this.

    2- If the .csproj files are in the correct locations, try adjusting the COPY paths in your Dockerfile as follows:

    • Removed the src/ directory from the COPY statements:
    • Adjusted WORKDIR paths: Changed the WORKDIR from /src/src/WebPortal.Web.Host to /src/WebPortal.Web.Host to align with the correct directory structure during the Docker build.
    FROM mcr.microsoft.com/dotnet/aspnet:7.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build
WORKDIR /src
COPY ["WebPortal.Web.Host/WebPortal.Web.Host.csproj", "WebPortal.Web.Host/"]
COPY ["WebPortal.Web.Core/WebPortal.Web.Core.csproj", "WebPortal.Web.Core/"]
