FakeLogger

This repository provides an application that uses Elixir GenStages to print fake logs to stdout.

Installation

To run locally, I recommend installing Elixir and Erlang as described here .tool-versions file. ASDF is the simplest way to execute Elixir; you can read about ASDF with Elixir here:

• Using ASDF to Manage Programming Language Runtime Versions

So run the following command to install Elixir requirements.

# install rebar and hex
mix local.hex --force &&  mix local.rebar --force

# get all deps
mix deps.get --all

How to run?

After that, we can run the project with mix.

mix run --no-halt

You may test a Docker image from my DockerHub repository:

• willsenabr/fake-logger

# docker with delay
docker run -it --rm --env DELAY=5000 docker.io/willsenabr/fake-logger

# podman default delay
podman run -it --rm  docker.io/willsenabr/fake-logger

Tests

Of course, there is test coverage, which you can run using the command:

mix test

Release

Elixir enables us to produce releases from your project, which is awesome.

MIX_ENV=prod mix release

# starting release
_build/prod/rel/fake_logger/bin/fake_logger start
