# create a redis app
flynn create --remote "" redis

# create a release using the latest (at the time of writing) Docker Redis image
flynn -a redis release add -f config.json "https://registry.hub.docker.com/_/redis?tag=3.0.2"

# scale the server to one process. This may time out initially as the server pulls the image, but watch "flynn -a redis ps" and should come up.
flynn -a redis scale server=1

# redis should now be running in the cluster at redis.discoverd:6379

Producer consumer pattern

Question: Can you write code implementing the consumer and producer pattern?

This is a classic concurrency problem where we have threads generating data to be consumed (producers) by other threads (consumers).

The implementation with POSIX threads can be a pain in the ass but it is quite straight forward in golang thanks to its concurrency constructs.
