Operating System: Docker for Windows. OSType: linux. Architecture: x86_64
I have an ASP.NET core web app running inside a Docker container. The below is my Dockerfile.
FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base WORKDIR /app EXPOSE 6002 FROM microsoft/dotnet:2.1-sdk AS build WORKDIR /src COPY ["AdvPersonApi.csproj", "AdvPersonApi/"] RUN dotnet restore "AdvPersonApi/AdvPersonApi.csproj" COPY . ./AdvPersonApi/ WORKDIR "/src/AdvPersonApi" RUN dotnet build "AdvPersonApi.csproj" -c Release -o /app FROM build AS publish RUN dotnet publish "AdvPersonApi.csproj" -c Release -o /app FROM base AS final WORKDIR /app COPY --from=publish /app . EXPOSE 6002 ENTRYPOINT ["dotnet", "AdvPersonApi.dll"]
The app builds successfully. I also am able to create the Docker image, and run it. I want the app to be accessible at localhost:6002. I used the below command to create the container:
docker run -p 6002:6002 --name advpersonapicontainerv2 advpersonapi:v2
I see that the containers are created and running.
The below is the result of docker ps:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 0484b184aeb8 advpersonapi:v2 "dotnet AdvPersonApi…" About a minute ago Up About a minute 0.0.0.0:6002->6002/tcp advpersonapicontainerv2
The issue is that I am not able to access the app at Container port 6002. The below command gives connection refused:
docker exec 0484b184aeb8 curl http://localhost:6002/api/person/time % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 curl: (7) Failed to connect to localhost port 6002: Connection refused
However, if I try
docker exec 0484b184aeb8 curl http:// localhost:80 /api/person/time
I get the response. What should I do to map the host port 6002 correctly to the container port 6002?
I also tried getting into the container, by using docker exec -it 0484b184aeb8 bash. I tried netstat -a, and I don’t see port 6002 in the listening list. I tried resetting Docker to factory settings, but issue still persists.
