MyNotes:

• yugabyte RF minimum 3 with 4 node if we want 1 node failover. because table data split to tablets evey tablet should have leader and follower node. we should have minimum 2 copy to accessing data.
• all documentation run with docker run --bla --blabla ... ok it's run & i can test it. but i want to create config for portability
• docker compose file and all images build from .Dockerfile is good idea for portability and development.
• i try create a configuration in this repository.

fresh start

docker compose down --rmi all --volumes --remove-orphans
