Docker configuration

We have a several Docker configurations.

You need docker and docker-compose installed (for MacOS just use the official app).

Setup

# clone and go to gg
git clone https://github.com/StanfordSNR/gg.git
cd gg

# build containers
docker-compose build

To continue, you should set environment variables to access AWS. One way is to create a .env file at the root of the project. Read more about these environment variables here.

Here is an example:

# cat .env
GG_LAMBDA_ROLE=arn:aws:iam::238398044701:role/gg
GG_STORAGE_URI=s3:https://gg-ruby/?region=eu-north-1
AWS_ACCESS_KEY_ID=sXZaZmYdssmxviw
AWS_SECRET_ACCESS_KEY=msKDhYhwQeQZwvh/TOas6TO/dpIYn8n
AWS_REGION=eu-north-1
# compile gg
docker-compose run --rm runner -c ./docker/bin/compile

# setup serverless functions
docker-compose run --rm runner -c ./docker/bin/ggfunctions

# GEN      ggfunctions
# Installing lambda function gg-lambda-function... arn:aws:lambda:eu-north-1:12345678:function:gg-lambda-function
# done.
# Installing lambda function gg-meow-function... arn:aws:lambda:eu-north-1:12345678:function:gg-meow-function
# done.

Use

After successful completion of the commands above you can use gg

docker-compose run --rm runner -c /bin/bash
root@88d653b86453:/app/gg# gg
gg COMMAND [ARG]...

TIP: Docker doesn't cleanup after itself well, so you have to do it manually.

# to monitor disk usage
docker system df

# to stop and clean application related containers
docker-compose down

# and with volumes (useful to reset databases state)
docker-compose down --volumes

# or even clean the whole docker system (it'll affect other applications too!)
docker system prune

TIP2: Use --rm flag with run command to automatically destroy the container on exit, e.g. docker-compose run --rm runner.

TIP3: Out of the box Dockerfile contains two stages:

  • build-env provides a minimal environment to build & run gg framework. Used for TravisCI.
  • sandbox-env provides a container with all dependencies to play with gg's examples.

If you are interested in other behaviors, you can use multi-stage build feature to build your own containers.
