add Dockerfile and notes

[inceabdullah]

Hello,

I generally use openfortivpn with docker. There are some fortivpnclient docker images but not openfortivpn. So I would like to add Dockerfle to use it everywhere.

in Docker needed two param --privileged --cap-add=NET_ADMIN and --net host

There two options to run it

docker run --privileged --cap-add=NET_ADMIN --net host -d -v config:/etc/openfortivpn/config openforticlient

or could be run with other params like --set-dns=0 --pppd-use-peerdns=1

docker run --privileged --cap-add=NET_ADMIN --net host -d -v config:/etc/openfortivpn/config openforticlient -c /etc/openfortivpn/config --set-dns=0 --pppd-use-peerdns=1

Thank you.

Hello,

Having a Docker image for openfortivpn is a good idea, but like for distribution packages (rpm, deb, flatpak, etc.) I believe it's better not to maintain them here.
