I am building a simple DotnetCore application with docker-compose support with VS2017.
I have two Dockerfile, one for the app and one for an NGINX proxy. On top of that, there is a docker-compose.yml file that wraps both of these together.
This is the aspnetcore app Dockerfile, there’s many COPY statement in there and they all work properly!
FROM microsoft/dotnet:2.0-runtime AS base WORKDIR /app FROM microsoft/dotnet:2.0-sdk AS build WORKDIR /src COPY CoreServer.sln ./ COPY CoreServer/CoreServer.csproj CoreServer/ RUN dotnet restore -nowarn:msb3202,nu1503 COPY . . WORKDIR /src/CoreServer RUN dotnet build -c Release -o /app FROM build AS publish RUN dotnet publish -c Release -o /app FROM base AS final WORKDIR /app COPY --from=publish /app . ENTRYPOINT ["dotnet", "CoreServer.dll"]
This is the nginx Dockerfile which can’t manage to copy files properly. Instead, it outputs the following error:
COPY failed: stat /var/lib/docker/tmp/docker-builder780242597/nginx.conf: no such file or directory. #1859
FROM nginx WORKDIR /etc/nginx COPY nginx.conf ./ COPY server.crt ./ COPY server.key ./
I tried building this Dockerfile by itself and it works, but when I use docker-compose it gives the error above.
This is what the docker-compose.yml file looks like
version: '3' services: coreserver: image: coreserver build: context: . dockerfile: CoreServer/Dockerfile expose: - "5000" nginx: build: context: . dockerfile: nginx/Dockerfile ports: - "80:80" - "443:443" links: - coreserver
If you want to look at the full project, it’s a dotnetcore websocket server test application with a server and a client application.
Can somebody tell me what I’m doing wrong to have docker send give this particular error ?
