Docker cluster definitions
This directory contains multiple docker cluster definitions to start local pseudo cluster with different configuration.
It helps to start local (multi-node like) pseudo cluster with docker and docker-compose and obviously it's not for production.
You may find more information in the specific subdirectories but in generic you can use the following commands:
Usage
To start a cluster go to a subdirectory and start the cluster:
docker-compose up -d
You can check the logs of all the components with:
docker-compose logs
In case of a problem you can destroy the cluster an delete all the local state with:
docker-compose down
(Note: a simple docker-compose stop may not delete all the local data).
You can scale up and down the components:
docker-compose scale datanode=5
Usually the key webui ports are published on the docker host.
