Please create the network manually using `docker network create frontend` and try again. If this is right, how should I create the frontend network? Right now if I try to run docker-compose up I get this error because the network does not exist: $ docker-compose upĮRROR: Network frontend declared as external, but could not be found. Is this right? Basically, I want (A) to have access to (B) and the outside world to have access to (A) but not (B). To get everything up and running I wrote the following docker-compose: version: '3.7' Then shinyapptest makes its API calls to ". To do this I created a network backend by running the following command: docker network create -d bridge -subnet 192.168.0.0/24 -gateway 192.168.0.1 backend HTTP request sent, awaiting response.Suppose I have 2 docker containers: (A) shinyapptest is a front end that needs to communicate with (B) testapi and be accessible to the outside world. # wget -O /tmp/test.html - 16:56:27- Resolving localhost (localhost). Now listening on: # docker port radiusnet # docker run -name radiusnet -network host radiusnet When started with "-network host", "docker port" may report nothing, while the docker is servicing nicely. If this fails, the wrong ports have been published. # wget -O /tmp/test.html - 16:22:46- Resolving localhost (localhost). # docker run -name radiusnet -p 8001-8009:5000/tcp radiusnet The listening ports are reported by "docker port", but they don't guarantee they will be serviced. "-p 8000:80" when a service is running on port 5000
it's no use publishing a port the docker isn't servicing (eg. in Dockerfile, "EXPOSE 80" is used by "docker run -P", "publish all". Link to github project (if it's needed): Īny help - at this point will be greatly appreciated If any more information is needed please ask, I'm pretty new to Docker so I just did a bit of a knowledge dump of my current situation. RUN dotnet publish -c Release -o out -r linux-armįROM microsoft/dotnet:2.0.0-runtime-stretch-arm32v7ĬOPY -from=build-env /app/src/RadiusNet.Web/out. # copy csproj and restore as distinct layers Here's my docker file for anyone interested: FROM microsoft/aspnetcore-build:2.0 AS build-env The docker documentation does suggest running `docker inspect -f "" myapp gives me a different ip address to my ips internal ip address, which I've tried on port 8080 and get the same resultĭoing a curl on both addresses gives me the same result of connection refused: #Docker network internal how to#
I think at this point I'm at a bit of a lose as to how to access this thing.
adding -network=host to the docker run command. When I've been searching around for this people have suggested adding these flags (which I have tried and come up with the same results: I have docker pulled my repository onto my pi:ĭocker run -d -p 8080:80 joro550/radiusnet -network=hostīut when I go to my pi's ip address on port 8080 then I get this: You therefore need to listen on the external IP inside the container, and the easiest way to do that is by listening on all interfaces: 0.0.0.0. I have setup an account on docker cloud which build everytime I push to my github repo. docker run -p 5000:5000 will forward from all interfaces in the main network namespace (or more accurately, the one where the Docker daemon is running) to the external IP in the container. I have a repository on github that is a simplistic asp.net core project. I'm attempting to run a asp.net core application from a raspberry pi using docker, I think I have the main parts down.
