exdm - Elixir Deployment Manager

exdm is intended to complement exrm, by simplifying deployment of releases.

exdm provides a set of mix tasks to deploy applications, check their status and start and stop them.

Releases created by exrm are pushed to remote servers and applications can be upgraded.

exdm allows the definition of multiple stages for your appplication, e.g. production, staging and ci.

Usage

deps:

defp deps do
  [{:exdm, "~> 0.0.1"}]
end

Add a section to your application config:

config :exdm, :production,
  host: "example.com",
  user: "deploy",
  application_path: "/srv/my_app"

Build the release using exrm:

MIX_ENV=prod mix release

mix deployment.deploy production

This checks the following:

• is a release available of the current version of the application?
• is the application running on the remote host?
• if so, is it possible to upgrade from the local release from the current state?
• if not, exdm will try to run the initial deployment.

Other tasks

mix deployment.local              # prints the latest release version built locally
mix deployment.remote {stage}     # prints the version running on the remote host
mix deployment.can_deploy {stage} # are we ready to deploy?
mix deployment.start {stage}      # start the application
mix deployment.stop {stage}       # stop the application
mix deployment.is_running {stage} # stop the application
