Nagini is a snake who battles at: http://battlesnake.io

To start your Phoenix server:

• Install dependencies with mix deps.get
• Set up the event store with mix do event_store.create, event_store.init
• Start Phoenix endpoint with mix phx.server

Now you can use localhost:4000 as a Battlesnake endpoint.

The logger is configured to log at the debug level (very verbose) and logs are stored in /tmp/nagini.log. This is a workaround for Nanobox stdout log streaming being broken.

To start your Ember admin frontend:

• Change to the frontend directory with cd admin
• Install dependencies with npm install
• Start Ember with ./node_modules/.bin/ember serve

Now you can view localhost:4200/admin/

To customize your snake, set these environment variables:

• SNAKE_COLOR
• SNAKE_HEAD
• SNAKE_TAIL

To tune the solver, set these environment variables:

• SOLVER_TIMEOUT=infinity
• SOLVER_DEPTH=0

• Install Docker
• Install Nanobox CLI and log in
• nanobox dns add local nagini.local
• nanobox run
• Install dependencies and run start commands as normal

Note that Nanobox's Elixir engine may run a different version of Elixir than this project's .tool-versions lock file expects. This may not behave as intended.

Test with a dry-run first:

• nanobox evar add dry-run PORT=8080 MIX_ENV=prod EMBER_ENV=production
• nanobox evar add dry-run ADMIN_USER=fixme ADMIN_PASS=fixme
• nanobox evar add dry-run APPSIGNAL_APP_NAME="Nagini" APPSIGNAL_APP_ENV="dry-run" APPSIGNAL_PUSH_API_KEY="FIXME"
• nanobox deploy dry-run
• Test the dry-run deployed endpoint

Update the release version:

• Edit mix.exs

Deploy:

• nanobox remote add app-name
• nanobox evar add app-name PORT=8080 MIX_ENV=prod EMBER_ENV=production
• nanobox evar add app-name ADMIN_USER=fixme ADMIN_PASS=fixme
• nanobox evar add app-name APPSIGNAL_APP_NAME="Nagini" APPSIGNAL_APP_ENV="prod" APPSIGNAL_PUSH_API_KEY="FIXME"
• nanobox deploy

Monitoring is set up to work with AppSignal if the environment is configured.

To read the Nanobox server logs:

• nanobox console app-name web.main
• tail -f /tmp/nagini.log

• nanobox console app-name web.main
• iex -S mix phx.server --no-start

The --no-start option prevents the normal applications from being started because that would throw errors such as the port being in use.

• Find IP and password with nanobox info local
• PGPASSWORD="" psql -h IP -p 5432 -U nanobox gonano

• Start the tunnel with nanobox tunnel data.event_store -p 5432
• Find the password from Nanobox dashboard
• psql -p 5432 -h 127.0.0.1 gonano nanobox
• Enter the password`
