Setup a Scylla Cluster

This section describes how to set up the three-node cluster, which will be used throughout this course. This isn’t a stand-alone lesson, and some other lessons use the procedure below.


Before we proceed with the Scylla installation, please ensure that your environment meets the following prerequisites:

  1. Docker for MacWindows, or Unix. Please note that running Scylla in Docker is recommended for testing and evaluation. Use caution when doing this in a production environment.
  2. This Git repository.
  3. 3GB of RAM or greater for Docker.
  4. If you are using Linux, you will need docker-compose.

Now let’s proceed and get a three-node cluster up and running in Docker.

If you haven’t done so yet, download the example from git:

git clone

Setting up a Cluster

If you have already set up a cluster in previous lessons, stop and remove it by stopping all the containers.

Note: the following stops and removes all containers in the system. Make sure that you don’t delete other non-Scylla related containers!

docker stop $(docker ps -aq)
docker rm $(docker ps -aq)

Now, use docker-compose to set up the cluster:

cd scylla-code-samples/mms
docker-compose up -d

After a minute or so, the MMS should be up and running. Let’s verify this:

docker exec -it scylla-node1 nodetool status

Using nodetool, we can see that all three nodes are up and running in the cluster.
