Instances

Simple Deploy is built to manage Instances with the following assumptions:

  • A stack is comprised of Instances performing one role (App Tier, Web Tier, Etc.) per Cloud Formation stack.
  • Multiple Cloud Formation stacks are loosly coupled to build more complex topoligies.
  • Instances within a Cloud Formation Stack are part of an Auto Scaling Group.

All operations Simple Deploy performs which affect an instnace (Deploy, Exec) are performed against all instances in a Stack.

Listing Instances

To list all instances within a stack:

# simple_deploy instances -n app-stack -e default
[
  "54.241.84.40",
  "50.18.22.164"
]

Deploy

To execute a deploy against a stack and update the Chef Repo to Version 1.0.0:

# simple_deploy deploy -n app-stack -e default -a chef_repo=1.0.0
2012-12-13 09:05:02 -0800 INFO : Read chef_repo=1.0.0

Execute

To execute 'uname -a' across all instances in a given stack:
