Check

A collaborative media annotation platform.

This is a Docker Compose configuration that spins up the whole Check app locally. Tested on Linux and Mac OS X. The repo contains two Docker Compose files, one for development (docker-compose.yml) and the other for testing (docker-test.yml).

DO NOT USE IN PRODUCTION! THIS IS ONLY MEANT AS A DEVELOPMENT ENVIRONMENT.

Quick start

• Install docker-compose
• Update your virtual memory settings, e.g. by setting vm.max_map_count=262144 in /etc/sysctl.conf
• git clone --recursive git@github.com:meedan/check.git && cd check
• bin/first-build.sh and wait (for about one hour this first time!!) for a string in the log that looks like web_1_88cd0bd245b7 | [21:07:07] [webpack:build:web:dev] Time: 83439ms
• Open http://localhost:3333
• Click "Create a new account with email" and enter your desired credentials
• docker-compose exec api bash
• bundle exec rails c
• me = User.last; me.confirm; me.is_admin = true; me.save
• Go back to http://localhost:3333
• Click "I already have an account" and login using your credentials
• Enjoy Check! 🎉

Available services and container names

• Check service Admin UI (container api) at http://localhost:3000/admin
• Check service GraphQL at http://localhost:3000/graphiql
• Check Slack Bot (container bot) at check-bot/dist, a ZIP file that should be deployed to AWS Lambda
• Pender service API (container pender) at http://localhost:3200/api - use dev as API key
• Alegre service API (container alegre) at http://localhost:3100
• MinIO storage service UI (container minio) at http://localhost:9000 - use AKIAIOSFODNN7EXAMPLE / wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY to login
• Elasticsearch API (container elasticsearch) at http://localhost:9200
• Kibana Elasticsearch UI (container kibana) at http://localhost:5601
• PostgreSQL (container postgres) at localhost:5432 (use a standard Pg admin tool to connect)
• Chromedriver (container chromedriver in test mode) at http://localhost:4444/wd/hub
• Chromedriver VNC at localhost:5900 (use a standard VNC client to connect with password secret)
• Narcissus screenshot service (container narcissus) at http://localhost:8687
• Fetch fact-checking service (container fetch) at http://localhost:8687/about

Testing

• Start the app in test mode: docker-compose -f docker-compose.yml -f docker-test.yml up
• Check web client: docker-compose exec web npm run test
• Check browser extension: docker-compose exec mark npm run test
• Check service API: docker-compose exec api bundle exec rake test
• Pender service API: docker-compose exec pender bundle exec rake test
• Check Slack Bot: docker-compose exec bot npm run test
• Narcissus: docker-compose exec narcissus npm run test
• Fetch: docker-compose exec fetch bundle exec rake test
• Running a specific Check web client test: docker-compose exec web bash -c "cd test && rspec --example KEYWORD spec/integration_spec.rb"
• Running a specific Check API or Pender test (from within the container): bundle exec ruby -I"lib:test" test/path/to/specific_test.rb -n /.*KEYWORD.*/

Helpful one-liners and scripts

• Update submodules to their latest commit: ./bin/git-update.sh
• Pack your local config files: ./bin/tar-config.sh
• Restart a service, e.g. Check API: docker-compose run api bash -c "touch tmp/restart.txt"
• Invoke the Rails console on a service, e.g. Check API: docker-compose run api bundle exec rails c d
• Update the Relay schema file on Check API: docker-compose run api bundle exec rake lapis:graphql:schema

Upgrading databases in development environment

We have recently upgraded to Postgres version 11 from 9.5. This necessitates a migration of existing databases to the new version. The migration will create a new data volume, so make sure you have enough storage space for a second copy of your databases. To migrate run these commands:

docker-compose down
docker-compose -f docker-upgradedb.yml up
docker run --rm -v check_postgres11:/var/lib/postgresql/data -u postgres -it postgres:11 bash -c "echo host all all 0.0.0.0/0 md5 >> /var/lib/postgresql/data/pg_hba.conf"
docker-compose up --remove-orphans --abort-on-container-exit

This will leave behind your original data volume and which you can clean up by running docker volume rm check_postgres.

Troubleshooting

• If you're having trouble starting Elasticsearch on macOS, with the error container_name exited with code 137, you will need to adjust your Docker settings, as per https://www.petefreitag.com/item/848.cfm
• If you're getting an error starting chromedriver in test mode, like the following:

docker-compose -f docker-compose.yml -f docker-test.yml up --abort-on-container-exit
Starting check_elasticsearch_1_2e69e84ccb56 ...
Starting check_chromedriver_1_6a1e9d8f5fd4  ... error
