Docker: Finding the URI for Redis image to reference in ECS

Question

I am using Redis locally for a caching service in my Docker project. For my other services, I built the images, and pushed them to ECR. The Redis service is the standard service.

services:

  redis:
    image: redis:3.2

Question How do you find the URI for a standard image like this to reference in the container to my Task Definition?

Answer 1

According to the ECS documentation you should be able to use “short” names for images on Docker Hub: try just typing in redis:3.2 there and see if it works.

If all of the parts (server hostname, namespace, image name) are really required, docker.io/library/redis:3.2 is the exact same image, just with the typical Docker Hub defaults filled in.
