# NOT FOR PRODUCTION, JUST FOR LOCAL RACKS!!!!!
# I use this convox.yml to setup local gen2 rack services.  
# NOT for apps that have their own resources defined, these are resources are shared across multiple apps
# In production, these are either non-convox SaaS (e.g., I use Elastic cloud for my prod elasticsearch)
#  *or* I set them up with `convox resources create` (e.g., my shared redis)
# This config is just a handy way to have local dev services running that my local convox rack can use.
resources:
  # Any resources here exposed locally as <resourcename>.resource.<appname>.convox
  redis:
    type: redis
