How to generate keys (if you don't have them)

For newbies who don't use ssh, here's the incantation to create your own key pair:

$ ssh-keygen -t rsa -C "your@email.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/yourusername/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in test_rsa.
Your public key has been saved in test_rsa.pub.
The key fingerprint is:
3b:1a:42:c2:54:b4:db:9c:10:a0:56:0d:5d:ec:73:32 your@email.com

Requirements

To get this server to work without internet connectivity the following repos need to be installed:

• eugeneware/buildstep - custom buildpack builder which will use a custom node.js heroku buildpack which bypasses the dependenciesd on semver.io and s3pository.heroku.com for node buildpacks. This needs to be built as a docker image and installed on the dokku server as progrium/buildstep.
• semver.io - needs to be running, preferably on the dokku server, and also running SSL.
• s3pository.heroku.com a mirror of the node.js linux binaries needs to running as well (preferably on the dokku server).
• npm - A local mirror of npm needs to exist and be listening on npm.campjs.com. The .npmrc of the custom nodejs buildpack has been modified to point to this address.
• dnsmasq to fool the servers into thinking that they are connected, we need to reroute some DNS entries to our local servers. There also needs to be an entry in /etc/default/docker to change the DNS server passed to docker containers to be the local dnsmasq server. (NB: This should probably be a docker-args hook). To be run like:

docker run -name dnsmasq -v=/etc/dnsmasq.hosts:/dnsmasq.hosts -p='53:5353/udp' -d eugeneware/dnsmasq

TODO

• Make dokku resolve against local npm server
• Local APT repo?
• Download a bunch of common build packs
• Local www server to store these instructions or even provide a web interface to add the keys.
