Just build it or pull it from andrey0001/pritunl. Run it something like this:

docker run --privileged --name pritunl --restart unless-stopped  --net=host -d -t andrey0001/pritunl

If you have a mongodb somewhere you'd like to use for this rather than starting the built-in one you can do so through the MONGODB_URI env var like this:

docker run --privileged -e MONGODB_URI=mongodb:https://some-mongo-host:27017/pritunl --name pritunl --restart unless-stopped  --net=host -d -t andrey0001/pritunl

Then you can login to your pritunl web ui at https://docker-host-address/ Username: pritunl Password: pritunl

Then change 443 port to 9700 in Settings

To disable listen on 80 port, enter to the container:

docker exec -it pritunl bash

and run:

pritunl set app.redirect_server false

To enable LZO compression, create server and organization, attach organization to the server, then connect to the container:

docker exec -it pritunl bash

connect to mongo:

mongo pritunl

and run:

db.servers.update({}, {$set: {"lzo_compression" : true}}, { multi: true })

Then you're on your own, but take a look at http:https://pritunl.com or https://github.com/pritunl/pritunl
