Returns the options of a Lambda release.

strip_iex(release)

Release step removing the :iex application from the release and its boot scripts, for a smaller package. bin/lambda remote won't work without it.

Functions

lambda(opts \\ [])

@spec lambda(keyword()) :: keyword()

Returns the options of a Lambda release.

The defaults are include_erts: false (ERTS comes from the OTP layer), include_executables_for: [:unix], strip_beams: true, quiet: true and a rel_templates_path providing the vm.args, env.sh and bootstrap files Lambda expects. Any mix release option given in opts overrides them.

The release must be named lambda, as bootstrap starts bin/lambda.

Options

  • :strip_iex - when true, removes IEx from the release with strip_iex/1.
  • :before_steps - a list of steps to run before the other steps.
  • :after_steps - a list of steps to run after the other steps.

Call it from an anonymous function in mix.exs, so it only runs once :aws_lambda_runtime is compiled:

releases: [lambda: fn -> AWS.Lambda.Runtime.Release.lambda(strip_iex: true) end]

strip_iex(release)

@spec strip_iex(Mix.Release.t()) :: Mix.Release.t()

Release step removing the :iex application from the release and its boot scripts, for a smaller package. bin/lambda remote won't work without it.
