Docker Compose config for Rails app

Create files with current user as owner on Linux

Use UID (or --user in run) flag on Linux as follows, so docker creates files with host user as the owner docker/compose#1532

UID=$(id -u) docker-compose run website bin/install

Debugging with pry

Two options:

1. Attach to running server container with

docker attach $(docker-compose ps | grep website_1 | awk '{print $1}')

2. Run server with this command instead of docker-compose up

UID=$(id -u) docker-compose run --use-aliases --service-ports website

Running tests

See spec/rails_helper.rb

You want to run feature tests in live mode and see how they go
Two options:

1. on your local machine

LIVE_CHROME=true rspec spec/features/reports_spec.rb

2. via VNC (not implemented) https://hub.docker.com/r/siomiz/chrome/

Issues

• wkhtmltopdf
  • wkhtmltopdf-binary - "file not found", alpine doesn't have some shared libraries
  • apk add wkhtmltopdf - blank page rendered

TODO

• remove password for postgres
• run chrome via VNC for tests
