View Source mix phx.gen.release (Phoenix v1.7.7)

Generates release files and optional Dockerfile for release-based deployments.

The following release files are created:

  • lib/app_name/release.ex - A release module containing tasks for running migrations inside a release

  • rel/overlays/bin/migrate - A migrate script for conveniently invoking the release system migrations

  • rel/overlays/bin/server - A server script for conveniently invoking the release system with environment variables to start the phoenix web server

Note, the rel/overlays directory is copied into the release build by default when running mix release.

To skip generating the migration-related files, use the --no-ecto flag. To force these migration-related files to be generated, the use --ecto flag.



When the --docker flag is passed, the following docker files are generated:

  • Dockerfile - The Dockerfile for use in any standard docker deployment

  • .dockerignore - A docker ignore file with standard elixir defaults

For extended release configuration, the mix release.init task can be used in addition to this task. See the Mix.Release docs for more details.
