The parameters are split into two halves, separated by a colon, the left hand side representing the host and the right the container side. For example with a port -p external:internal - what this shows is the port mapping from internal to external of the container. So -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 http://192.168.x.x:8080 would show you what's running INSIDE the container on port 80.
-v /data- Path to persistant data-e BRIDGE_ADDRESS="172.21.1.1/24"- Configure the internal NAT network bridge for GNS3
It is based on alpine-linux edge, for shell access whilst the container is running do docker exec -it gns3 /bin/sh.
This container works best when run priviledged and on a network other then dockers' default (host or macvtap for example). If you run on docker's default network you need to expose all ports used by gns3 and consoles yourself.
- To monitor the logs of the container in realtime
docker logs -f gns3.
