Your environment runs on Ubuntu 16.04 in a Docker container as a non-root user. Each of your containers will run in a separate network namespace, but the same mount and PID namespace.
Your job is to make a highly available distributed database...of counters. We will run N instances of the database. You are to build your challenge so that it extracts into the following layout:
challenge
challenge/bin
challenge/bin/challenge-executable
Your challenge, should you choose to accept it, involves building a storage service. The storage server is meant to store arbitrary data. You are to build a REST API (HTTP/1.1, or 2.0, your choice) that presents a data storage, and retrieval API.
Your environment runs on Ubuntu 16.04 in a Docker container as a non-root user. You are allowed to write to the current working directory.
You are to build your deliverable so that it extracts into the following layout:

This document offers rules for choosing host names, so that Netops can better manage the hosts in production. View the rules below through the eyes of Netops. They need to know, from the host name, what the host does and where it fits in the big picture. No matter how familiar a name is to you, if it means nothing to Netops, there may be better choices for your host name.
The Naming Czar has the power to enforce these rules, and is the final authority for host names.
This document sets rules only for host names, that is, the part of a full domain name up to the first dot. For example, for the domain name app01.p001.us-west-1.aws.xyz.com, the rules cover the name app01. This document does not set rules for for anything else, such as network names, DNS subdomain names, or appliance names.
This is a document currently under review. It is a draft document and may be updated, replaced, or obsoleted by other documents at any time.
