I have a program running inside a docker container and I expose the port 8888. However, when I try to connect the program from a device (in the same LAN as host machine but not the host machine) it failed.
Here is my docker file
FROM golang:1.10.1
…
RUN go build -buildmode=plugin -o plugin.so plugin.go
EXPOSE 8666:8888
And I start the container with
docker run -it -P --network host plugin:v0.3 bash
and run
go run program.go
in bash.
It says
2018/07/30 01:51:43 listening port 8888
But I cannot connect to the port from other device(which is in the same LAN as host machine but not the host machine)
then I tried
docker ps -a
It looks different in that the ports column are empty(Usually there should be a mapping?)
Docker version 18.06.0-ce, build 0ffa825
docker network inspect host
