# How to install FarmBot Web API on a Fresh Ubuntu 18.04.1 LTS Machine

# IMPORTANT NOTE: Resources are limited and Farmbot, inc. cannot provide
# longterm support to self-hosted users. For users who have never administered a
# Ruby on Rails applications, this presents an extremely high risk of data loss.
#
# IF YOU ARE NOT A DEVELOPER you are highly encouraged to use the my.farm.bot
# servers. Self hosted documentation is provided with the assumption that you
# have experience with Ruby/Javascript development. Self-hosting a Farmbot
# server is not a simple task.

# Remove old (possibly broke) docker versions
sudo apt-get remove docker docker-engine docker.io

# Install docker
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common --yes

#  http://YOUR_HOST:3000/.

# You can optionally verify installation by running unit tests.

# Create the database for the app to use:
sudo docker-compose run -e RAILS_ENV=test web bundle exec rails db:setup
# Run the tests in the "test" RAILS_ENV:
sudo docker-compose run -e RAILS_ENV=test web rspec spec
# Run user-interface unit tests:
sudo docker-compose run web npm run test
