Erlang/OTP in Docker
This project provides images of Erlang/OTP for Docker.
Key features
The project supplies pre-built releases for Docker platforms. You can also assemble Docker images by yourself, see the Getting started.
Serverless runtime
docker pull fogfish/erlang-serverless
The runtime is compatible with https://github.com/fogfish/serverless
Docker runtime
docker pull fogfish/erlang-alpine
The development and distribution of Erlang applications is achieved using release. The release contains complete application and all its dependencies, which makes it a perfect distribution package.
Erlang runtime environment to package and ship Erlang releases as Docker containers. Environments provides a minimal alpine image about 100MB.
<!-- Erlang **toolchains** to build Erlang application within the Docker environment. These toolchains are compatible with [Erlang Workflow](https://github.com/fogfish/makefile) and they are assembled from Erlang/OTP **sources**. Erlang/OTP **runtime**: - `fogfish/erlang-alpine-rt` - `fogfish/erlang-centos-rt` Erlang/OTP **toolchain** - `fogfish/erlang-alpine` - `fogfish/erlang-centos` Erlang/OTP **serverless** - `fogfish/erlang-serverless` -->Getting started
The project supplies pre-built releases for Docker platforms. You can also assemble Docker images by yourself running make command.
Ship your Erlang release with Dockerfile
FROM fogfish/erlang-alpine-rt
COPY _build/default/rel /rel
ENTRYPOINT spawn-erlang-node my-app
Do not forget to exclude ERTS when you are assembling release
{include_erts, false}.
As part of your application configuration vm.args set a node name:
-name ${ERL_NODE}
Build a docker images and run it using
docker run -it my-app
Bootstrap script spawns Erlang node container_id@hostname. You can customize the behavior
docker run -it -h=`hostname` my-app
docker run -it -h=`hostname` -e "NODE=app" my-app
docker run -it -e "NODE=app@localhost.localdomain" my-app
See Erlang Workflow for details about usage of Erlang toolchains. It assumes that rebar3 and relx tools are used for development.
