Title: Engineering Elixir Applications: Docker swarm services don’t come up (page 261)
Hi, I’m really enjoying the book and getting great practice. I’m to the point of setting up CD. But when I try to deploy to the stack in AWS I get messages similar to:
image postgres:15.2 could not be accessed on a registry to record
its digest. Each node will access postgres:15.2 independently,
possibly leading to different nodes running different
versions of the image.
Am I missing a step? Is the book missing a step? Have I messed up my environment in some way?

Finally - FYI I had the protocol on the terraform egress block for the security group set to “tcp”, probably from copypasta from the other blocks. As you have in the book it should be “-1”, although I don’t quite understand that yet.
Problem solved.
