Rainforest Docker Scripts

README.md

Why

Docker allows us to setup a consistent dev environment that is easy to start, upgrade and reset when required. It also does not pollute your local machines with rubishness if you dont work actively work on the backend.

1. Install Docker & Clone Gist

Install docker through docker toolbox here

Then clone this gist, at the same directory level as Rainforest & Regenwald (https://github.com/rainforestapp/regenwald) So the directory looks like

> folder
  > Rainforest
  > regenwald
  > docker-scripts

2. Build Docker Containers

Run the following command to pre-build docker containers for Redis, Postgres & Rails

docker-compose build

3. Setup DB

Setup your docker db container

docker-compose run --rm --service-ports web /rainforest/script/reset_db.sh

4. Setup DNS

Add the following lines to your hosts file. On Mac/Linux the file is located at /etc/hosts and on windows you can find it at C:\Windows\System32\Drivers\etc\hosts

127.0.0.1	app.rainforest.dev
127.0.0.1	admin.rainforest.dev
127.0.0.1	portal.rainforest.dev
127.0.0.1	vendor.rainforest.dev

Note: You may have to edit the file as root/Administrator

5. Start/Stop/Reset Docker

To start rainforest in docker, run

docker-compose up

This will start docker containers, and attach the logs to your terminal. Close the app (Ctrl + c) to stop the containers gracefully.

To reset your local rainforest docker setup, run

docker-compose rm -f -v
docker volume rm rainforest_data-volume
rm -f tmp/pids/server.pid
docker-compose run --rm --service-ports web /rainforest/script/reset_db.sh
