What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

Rancher

Rancher is an open source project that provides a complete platform for operating Docker in production. It provides infrastructure services such as multi-host networking, global and local load balancing, and volume snapshots.

This documentation describes how to run Rancher localy for development and evaluation propuses.

I'm using Docker for OSX (native) but even for this to work you will need to install VirtualBox.

#System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

##Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Overview

This gist demonstrates how to run a docker container with nomad, using a wrapper script.

Why would you want to use this?

With the wrapper, we can more easily run the container in the way we need to and without being limited by Nomad's docker driver. For example, while Nomad will have great support for volumes in the future, it has no such support right now, and the driver does not expose a config parameter to tune the volumes mounted in the docker container. This is also a great way to use consul to lookup services before starting your app, or to retrieve credentials from Vault. When running legacy applications with nomad, the wrapper script is the place to put that type of look-up logic.

We use a wrapper script and the raw_exec driver to run the container with the parameters we need.
