Where do default Kubernetes container images come from

svenmathijssen

Whenever we specify container images, where are they pulled from by default? For example in exercise 2.4, we are pulling an image called fluent/fluentd. Is there some sort of central registry for default Kubernetes images?

image: fluent/fluentd

I think I found the answer to my own question . They come from the docker.io central registry found at hub.docker.com

For fluentd: https://hub.docker.com/search?q=fluent/fluentd

The typical naming convention for images is:

registry/useraccount/repository:Tag

Container runtime has defaults configured. You can override the defaults by specifying full image names or modify the default configurations.
