⁠moby-counter

A simple app that is used to demonstrate keeping state inside a docker-compose app.

⁠run

$ docker-compose build
$ docker-compose up

This will expose the web application on port 80.

⁠Database backends

There are two versions of the moby app - one that saves data to Redis and one that saves it to Postgres.

⁠Redis

The default is to use the Redis connection - the envrionment variables that control this:

• USE_REDIS_HOST
• USE_REDIS_PORT

⁠Postgres

If any of the following variables are defined - it will force the app to use the Postgres backend:

• USE_POSTGRES_HOST
• USE_POSTGRES_PORT
• POSTGRES_USER
• POSTGRES_PASSWORD
