deploy_artifact

Overview

This cookbook provides a simple deploy_artifact resource that will deploy a single binary or tar.gz file. The deployment process is designed to mirror the Deploy Resource except designed to be used only for local deployments and not GIT. It is assumed that a directory called cached-copy will already contain the contents of what is to be deployed. It is left up to you on how to deliver the artifact while the resource will do the work to deploy it.

Given a file location and path, the resource will:
- Create a directory structure:

path\
cached-copy\
releases\
<CHECKSUM>\
current -> releases\<CHECKSUM>

- Assume the file is a single binary or gziped tar file
- Create a releases directory and release directory named as the MD5 checksum of the deployed file in path
- On successful completion, symlink the release directory releases\<CHECKSUM> to path\current
