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 [email protected]: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! 🎉

Note 1: For security reasons, not all credentials and configuration values are provided by copying .example files during the initial build. For Meedan members, you need to set your AWS_PROFILE environment variable, login to AWS (aws sso login) and then the script bin/first-build.sh will retrieve and set the required values for you. If you're not a Meedan member, you need to set at least the google_client_id and google_client_secret values in check-api/config/config.yml, here is how you can get those. Other optional features can be enabled by setting the required credentials, for example, the FACEBOOK APP ID is needed to get Facebook social metrics and to run the Facebook related tests.

Note 2: For performance reasons, some services (that are not needed to run the application with its basic functionality) are disabled by default (e.g., commented in the Docker Compose file). If you need those services, please uncomment them in docker-compose.yml. If you may need to increase the amount of memory allocated for Docker in order for it to work.

Note 3: There is a seed file you can run to create a new user and fake data, or to add fake data to an existing user. You can do that by running docker compose run api bundle exec rake db:seed. If you picked the option to create a new user it will print the user information when the script is done. If you picked the option to add data to a user, it will let you know it was successfully added when it's done.

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 -f docker-compose.yml -f docker-test.yml exec geckodriver bash -c "cd /home && chown -R root seluser" && 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 check-slack-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 test: docker-compose exec web bash -c "cd test && rspec --example KEYWORD spec/integration_spec.rb"
• Running a specific Check Mark test: docker-compose exec mark bash -c "cd test && rspec --example KEYWORD spec/app_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 and check if any example configuration files have been updated: ./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
• Update the JSON API schema file on Check API: docker-compose run api bundle exec rake jsonapi:resources:update_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
