Image with Phoenix elixir library in an Alpine distribution and wkhtmltopdf library
3.3K
A docker image based on alpine with everything you need to develop phoenix apps, with tools like nodejs and wkhtmltopdf out of the box.
Erlang and elixir are installed with asdf so new versions are easy to manage and upgrade.
Just add a docker-compose.yml to your project with something like this, and start developing!
version: '3.7'
volumes:
deps:
builds:
node_modules:
services:
phx:
image: hackvan/phoenix-alpine:1.5.4
ports:
- ${HTTP_PORT:-4000}:${HTTP_PORT:-4000}
volumes:
- ./:/app/src
- deps:/app/src/deps
- builds:/app/src/_build
- node_modules:/app/src/assets/node_modules
depends_on:
- postgres
environment:
- MIX_ENV=${ENV:-dev}
- POSTGRES_URL=ecto://postgres:postgres@postgres/your_app_name_${ENV:-dev}
- HTTP_PORT=${HTTP_PORT:-4000}
working_dir: /app/src
postgres:
image: postgres:9.6
ports:
- ${DATABASE_EXTERNAL_PORT:-5432}:5432
environment:
POSTGRES_HOST_AUTH_METHOD: "trust"
Then execute your app with simple commands:
# Commands to set-up your app
docker-compose run --rm phx sh -c "mix ecto.create"
docker-compose run --rm phx sh -c "mix ecto.migrate"
docker-compose run --rm phx sh -c "cd assets/node_modules && npm install"
# Start your server
docker-compose run --service-ports phx iex --sname your_app -S mix phx.server
# To run tests
ENV=test docker-compose run --rm phx sh -c "mix test"
Use this base image to build everything you need before deploy. Since the image is based on alpine, you can use a clean alpine image to deploy your app.

You can build, deploy or run your image locally, or using some CI tool like Drone to deploy wherever you want, everything with a unique Dockerfile
# Build with required envs.
docker build --build-arg GOOGLE_SECRET_JSON=$GOOGLE_SECRET_JSON --build-arg GH_TOKEN=${GH_TOKEN} --tag hackvan/elixir_app:latest .
# Test and run your image on localhost
docker run -it --env-file .env.prod -p 4080:4080 hackvan/elixir_app:latest
# Deploy your image to dockerhub
docker push hackvan/elixir_app:latest
