Hello,
Curious why you ended up leaving Rails and Redis in one container instead of using ElasticCache and having your docker images based on the web_only template...?
I was thinking of using your model here, but since you've got Rails and Redis tied together in one image, you can't create lots of images in parallel for auto-scaling... Curious if you tried to make that happen or not...
Thanks for taking the time to read this.
Sincerely,
Ryan
