Counter is a web application that increases the value of a counter every time it is clicked. The application uses PostgreSQL as its store.
This is configured by setting the environment variable POSTGRES_URL to a postgres endpoint such
as postgres://localhost.
# With binary and local Postgres
$ POSTGRES_URL=postgres://localhost counter-linux
# With docker and local Postgres
docker run -d -e POSTGRES_URL=postgres://localhost stigkj/counter
# Or with link, assuming a Postgres container named postgres is running
docker run -d --link postgres -e POSTGRES_URL=postgres://postgres@postgres stigkj/counter
