-DeployEx is a lightweight tool designed for managing deployments in Beam applications (Elixir, Gleam and Erlang) without relying on additional deployment tools like Docker or Kubernetes. Its primary goal is to utilize the release package for executing full deployments or hot-upgrades, depending on the package's content, while leveraging OTP distribution for monitoring and data extraction.

 DeployEx acts as a central deployment runner, gathering crucial deployment data such as the current version and release package contents. The content of the release package enables it to run for a full deployment or a hot-upgrade. Meanwhile, on the development front, your CI/CD pipeline takes charge of crafting and updating packages for the target release. This integration ensures that DeployEx is always equipped with the latest packages, ready to facilitate deployments.
