Underware

... and pants

A lightweight vanilla NodeJS microservicing platform. Each pair of "pants" are the building blocks for the services, and are meant to be modular and expandable.

Installing on Linux

There are two methods to get Underware setup and running on linux

NPM scripts (with sudo)

coming soon

Manual

Painful, however allows you to run Underware with out root access (still does require root access, but from your part not a script).

#install
npm install underware

#start (from within project root)
underware -http <port> -https <port>[ -u <uid>]

The start command changes slightly since you have to route port 80 and 443 to a port above 1024 to get around root. Optionally you can supply a uid for underware to use for services otherwise it will run as user (still not recommended).

#your homework:
#redirect port traffic (not the only way, but the easiest)
sudo iptables -t nat -A PREROUTING -i <interface> -p tcp --dport 80 -j REDIRECT --to-port <destination>
sudo iptables -t nat -A PREROUTING -i <interface> -p tcp --dport 443 -j REDIRECT --to-port <destination>

#create underware user (if using)
sudo useradd -u <uid> underware

As long as underware gets this uid, it is up to you to deescalate permissions.

Installing on Windows

Since privileged ports and user traversal are not existent in windows, the process is automated regardless.

#install
npm install underware

#start (from within project root)
underware

Important Notes

• On windows you cant run-as so any operations done, will be done with your permissions.
• Under no circumstance should the bulk of this script be run with root, there is a kill clause to prevent this DO NOT OVERRIDE!
• Root is only being requested to listen on priveleged ports and set up a low permission user (on linux). Permissions are dropped before any actual operations are done.
• pants-slacks package uses eval for templating. If you opt to use this feature be aware of the danger and design around it. This is the main reason a lower permission user is recommended.

What's in the Box?

• jeans - basic service meant to be long running
• shorts - start when needed, do their job, exit
• pjs - same thing as shorts, but in response to a clock
