stups-crate

stups appliance for the Crate.IO database.

This stups appliance is used to create a docker image that can be deployed to AWS using the senza definition in stups-crate.yaml.

In its current form it creates a 3 node cluster on c3.2xlarge instances storing data on 2 instance storage ssd drives that are combined into 1 level 0 raid.

All nodes are master and data nodes.

It uses aws discovery to discover other nodes of the cluster.

Data is stored in the following paths:

path:
  conf: /crate/config
  data: /data/data
  logs: /data/logs
  blobs: /data/blobs

Docker

It is important to have a stups-compliant docker image to include a current scm-source.json in the root folder. Use make to build your docker image:

$ DOCKER_IMAGE=pierone.stups.example.org/team/stups-crate:0.54.6 make build
