What it is

Problem: Terraform doesn't play nicely with pre-existing infrastructure.

Solution: Officially there isn't one - but here's a work-around that does the trick.

Summary

• Declare a new, temporary resource in your Terraform plan that is nearly identical to the extant resource.
• Apply the plan, thus instantiating the temporary "twinned" resource and building a state file.

-- Optimized MYSQL schema for datomic
-- Unfortunately the bin/sql/mysql-*.sql bootstrapping files for datomic are not

A Quick and Dirty Lens primer

Why does Lens exist? Well, Haskell records suck, for a number of reasons. I will enumerate them using this sample record.

data User = User { login    :: Text
                 , password :: ByteString
                 , email    :: Text
                 , created  :: UTCTime
 }
