Notice
Running Scylla in Docker is the simplest way to experiment with Scylla and we highly recommend it. However, running stateful containers is complex and tuning is needed to maximize the performance. Please follow our documentation before running it in production. We recommend that you use packages and follow Best Practices for Running Scylla on Docker.
Running a Single Instance
$ docker run --name scylla -d scylladb/scyllaAdding Nodes
$ docker run --name scylla-node2 -d scylladb/scylla --seeds="$(docker inspect --format='{{ .NetworkSettings.IPAddress }}' scylla)"$ docker run --name scylla-node3 -d scylladb/scylla --seeds="$(docker inspect --format='{{ .NetworkSettings.IPAddress }}' scylla)"Using Scylla in Docker
- You can verify that the cluster is up and running with the following command:
$ docker exec -it scylla nodetool statusDatacenter: datacenter1

Choose AMI
Amazon EC2 AMIs
Note that the Scylla AMIs will not work without an attached drive(s) for XFS.
Choose an Instance Type
For a production system, instances with a fast network and large SSD are recommended. The following instance is pre-tuned in the Scylla AMI and recommended for highest performance:
- i3 [i3.xlarge .. i3.16xlarge]
Other instance types will work, but with lesser permanence. If you do choose such a type, make sure to run scylla_io_setup.
Configure Instance Details
- Number of instances – base on your cluster planning
- Network – Select “Launch into EC2-Classic”, or your own VPC.
- Advanced Details – Open and add the following options (as text) to the User Data section.
| Option | Description |
| clustername | Required. The name of the cluster. |
| totalnodes | Required. The number of nodes you are adding to cluster. Use the same value as the “Number of instances” above. |
| seeds | Optional. An ip address of a node in an existing cluster. This will instruct Scylla to join an existing cluster. The “clustername” option must match that of the existing cluster. |
| stop-services | Optional. Do not start Scylla service on the nodes |
Example:
--clustername test-cluster
--totalnodes 3EC2 Configure Instance Details Capture
Add Storage
Scylla AMI require XFS to work. You Must attach at least one drive for Scylla to use as XFS for the data directory. When attaching more than one drive, AMI setup will install RAID0 on all of them.
The Scylla AMI requires at least two instance store volumes. The Scylla data directory will be formatted with XFS when the instance first boots. Scylla will fail to start if only one volume is configured.
Tag Instance
Configure Security Group
Make sure all Scylla Ports are open.
Review
Launch! You now have a running Scylla cluster on EC2.
To connect to the servers, use the username centos.
ssh -i your-key-pair.pem centos@ec2-public-ipDefault file paths:
- scylla.yaml at
/etc/scylla/scylla.yaml - data at
/var/lib/scylla/
To check that the Scylla server and the JMX component are running, run nodetool.
nodetool statusNote: This Scylla AMI does not support automatic multi-zone deployment.
Monitoring
It is highly recommended to have a Scylla monitoring stack in place. For more on how to setup Scylla monitoring with Grafana here
Reference
Scylla servers set up using this method have the system configuration covered on System Configuration Guide already applied. See the guide for a complete reference on settings used.
Scylla is a 100% open source project. You are welcome to run on Docker, Amazon EC2, or browse the source code and compile it directly from GitHub.
For binary downloads, we ask you to register so we can help you be as successful as possible and let you know about patches and fixes, learning resources, new features, and capabilities. We also invite you to share your feedback to help us improve Scylla.
