Ctrl

This is a simple gem to ease listing and sshing to instances in an AWS VPC.

Installation

$ gem install infra-ctrl

Add environment variables for AWS (direnv.net FTW):

• AWS_DEFAULT_REGION
• AWS_SECRET_ACCESS_KEY
• AWS_ACCESS_KEY_ID

As well as a couple for specifying the users to log in as when sshing to the nat and internal instances:

• CTRL_SSH_USER
• CTRL_SSH_NAT_USER

Notes

Assumptions about your infrastructure:

1. Instances with public ips are connected to directly using the CTRL_SSH_USER
2. Each instance has a tag:Environment
3. VPC private instances use the same user to log in
4. You have the necessary keys locally, and are fine forwarding your agent

Usage

$ ctrl ls <env> <instance name>
$ ctrl ssh <env> <instance name>
