Overcast is a simple command line program designed to make it easy to spin up, configure and manage clusters of machines, without the learning curve or complexity of existing server management tools.

Features

Create, reboot and destroy instances across DigitalOcean, Linode and Amazon, or locally using Vagrant + Virtualbox.

# Spin up a new Ubuntu 14.04 instance on DigitalOcean: $ overcast digitalocean create db-01 # Spin up a new Ubuntu 14.04 instance on Linode: $ overcast linode create db-02 # Spin up a new Ubuntu 14.04 instance on EC2: $ overcast aws create db-03 --user ubuntu $ overcast run db-03 allow_root_access_on_ec2 $ overcast instance update db-03 --user root # Spin up a new locally-running Ubuntu 14.04 Virtualbox instance: $ overcast virtualbox create db-04 # Upgrade and install Redis across all of those instances in parallel: $ overcast run db- * install/core install/redis --parallel

Run multiple commands or multiple scripts on any of your instances over SSH. Commands can be run sequentially or in parallel. Avoid vendor lock-in by running and testing your deployment scripts across different providers.

# Run bundled scripts, e.g. a LAMP stack: $ overcast run lamp-01 install/core install/apache install/mysql install/php # Run scripts relative to the current working directory or using absolute path: $ overcast run app-cluster ./recipes/my-app/install /path/to/script # Run sequences of commands and scripts across multiple machines in parallel: $ overcast run db ./script.sh uptime " free -m " " df -h " --parallel

Quickly SSH in to any instance by name.

$ overcast ssh app-01

Push and pull files between your local machine and any of your instances using SCP or rsync. Dynamically rewrite file paths to include the instance name using {instance} in either source or destination.

$ overcast push app nginx/myapp.conf /etc/nginx/sites-enabled/myapp.conf $ overcast pull all /etc/nginx/sites-enabled/myapp.conf nginx/{instance}.myapp.conf

Overcast is a thin wrapper around your SSH client and doesn't install or leave anything on the servers you communicate with, so Overcast itself has no real attack surface.

A library of scripts and recipes are included which make it easy to deploy a number of common software stacks and applications. The libraries were written for and tested against Ubuntu/Debian systems, but you can just as easily run your own custom scripts.

$ overcast run all /absolute/path/to/script ./relative/path/to/other/script

Concepts

Instances are any machine you can SSH into.

are any machine you can SSH into. Clusters are sets of instances.

Installation (OS X/Linux)

Install Node.js if not already installed. Install Overcast using npm. $ npm -g install overcast You can now use Overcast from any directory. Running any overcast command from anywhere will create the ~/.overcast config directory if it doesn't already exist. Add your API keys to ~/.overcast/variables.json to use their respective commands, either manually or using the var command: $ overcast var set AWS_KEY my_aws_key $ overcast var set AWS_SECRET my_aws_secret $ overcast var set DIGITALOCEAN_CLIENT_ID abc123 $ overcast var set DIGITALOCEAN_API_KEY abc123 $ overcast var set LINODE_API_KEY abc123 To make working with Overcast easier, you can add bash tab completion by adding the following to your .bash_profile : # Overcast Tab completion _overcast_completions () { local cur= ${COMP_WORDS[COMP_CWORD]} COMPREPLY=( $( compgen -W " ` overcast completions ` " -- " $cur " ) ) return 0 } complete -F _overcast_completions overcast

Installation (Windows)

Using Overcast on Windows is possible, but unsupported. Instructions TBD.

Uninstallation

Since Overcast is just a wrapper around SSH, there is nothing on your remote machines to uninstall. To uninstall Overcast from your local machine:

# To remove the Overcast package: $ npm -g remove overcast # Optionally delete your Overcast SSH keys and configuration files: $ rm -rf ~ /.overcast

Configuration

Overcast looks for an .overcast directory in the current directory, a parent directory, or ~/.overcast , in that order. This means you can have multiple configurations and treat your server infrastructure like source code.

The command overcast init will create a new configuration in the current directory. The config directory looks like this:

/.overcast /files # Files to be pushed to / pulled from instances /keys # SSH keys, can be your own or auto-generated by overcast overcast.key overcast.key.pub /scripts # Scripts to be run on instances clusters.json # Cluster/instance definitions (see example.clusters.json) variables.json # API keys, etc (see example.variables.json)

Design Goals

There are many server management frameworks out there already, but they generally involve a complex server-client implementation, a steep learning curve, or a giant, monolithic conceptual framework that requires taking a course to understand.

I wanted something that had little to no learning curve, that did only what you asked it to do on the remote machines and nothing more, that just focused on multi-server provisioning and communication and leaves problems like process/state management and system monitoring to tools designed specifically for those problems.
