* chore: tune up the hobby deploy testing * quick fix * put everything in the class * include release tag in name * split this out into stages for GA * test throwing ci off * fix * test destroy * check env * exit if things don't work out * debug * somewhat important to create the dns record here hah * record name as well * maybe? * update user_data * set dns ttl to 30 sec * silly dns mistake * correct DNS error
