alertlogic/erllambda repository overview

⁠AWS Lambda Erlang docker

This is used as docker base image for developing AWS Lambda⁠ functions running on BEAM.

The goal is to provide images which can be used to build zip packages suitable for deployment as AWS Lambda functions with a provided BEAM runtime.

Please see erllambda⁠ for further details on how to run and deploy Erlang AWS Lambda functions.

⁠Usage example

⁠Obtain an image

⁠Pull from official docker hub registry

Simply pull image from docker hub with a required Erlang version:

$ docker pull alertlogic/erllambda:20.3

⁠Build image from sources

To build image locally clone repository:

$ git clone https://github.com/alertlogic/erllambda_docker.git

Specify path to a Dockerfile with a required version to build an image:

$ docker build -t alertlogic/erllambda:20.3 ./erllambda_docker/20

⁠Running

⁠Erlang shell

$ docker run -it --rm alertlogic/erllambda:20.3
Erlang/OTP 20 [erts-9.3.3.5] [source] [64-bit] [smp:3:3] [ds:3:3:10] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V9.3.3.5  (abort with ^G)

⁠Build a package (rebar3_erllambda⁠ example)

$ docker run -it --rm -v `pwd`:/buildroot -w /buildroot alertlogic/erllambda:20.3 \
      rebar3 as prod erllambda zip

⁠Design

1. Erlang images are based on lambci/lambda-base:build image⁠, which replicates the live AWS Lambda environment almost identically.
2. Erlang OTP is built from source code⁠.
3. Elixir images are based on alertlogic/erllambda:<version> images.
4. rebar⁠ and rebar3⁠ tools are built from source and bundled in Erlang images.
5. mix⁠ tool is installed from hex⁠ and bundled in Elixir images.
