A release is a complete build of the application being -# deployed. This can be a clone of a repository for example, or a sync of a local folder on your filesystem. -# Having timestamped folders is one way of having distinct releases, but you could choose your own strategy like -# git tags or commit hashes. -# -# During a deploy, a new folder should be created in the releases folder and any build steps required should be -# performed. Once the new build is ready, the deploy procedure is 'finalized' by replacing the 'current' symlink -# with a link to this build. -# -# The 'shared' folder holds any resource that is shared between releases. Examples of this are web-server -# session files, or files uploaded by users of your application. It's quite common to have symlinks from a release -# folder pointing to a shared/subfolder, and creating these links would be automated as part of the build steps. -# -# The 'current' symlink points to one of the releases. Probably the latest one, unless a deploy is in progress. -# The web-server's root for the project will go through this symlink, so the 'downtime' when switching to a new -# release is reduced to the time it takes to switch the link. -# -# To distinguish between successful builds and unfinished ones, a file can be placed in the folder of the release -# that is currently in progress. The existence of this file will mark it as unfinished, and allow an automated -# procedure to remove it during cleanup. - - -# Typical usage -- name: Initialize the deploy root and gather facts - deploy_helper: -
