What's the default registry and images used for both the operator and ES itself.
Where can I find the Dockerfiles for the ES images ?
I've skimmed the operator repo but not sure where I'd find these in the code.
Am I correct they come from docker.elastic.co ?
Dockerfile for ES would be this ?
ECK is using the official Elasticsearch docker images as listed here https://www.docker.elastic.co/
And yes, that's the Dockerfile you linked to.
