Run in Docker

New in version 1.3.1: Scylla Manager

The best way to run Scylla Manager in a Docker container is by using the official Scylla Manager Docker image. You can pull the image directly from Docker Hub.

docker pull scylladb/scylla-manager

Scylla Manager is using Scylla as backend storage. When running Scylla Manager in a Docker container, you can either use an existing Scylla cluster as a backend or run a dedicated Scylla container and link them. This can be done automatically with docker-compose (refer to Running with docker-compose) or manually with plain Docker command (refer to Running with docker).


Scylla Manager for Scylla Open Source users is limited to 5 nodes. See the Scylla Manager Proprietary Software License Agreement.

Running with docker-compose

Docker compose is a tool for defining and running multi-container applications.


  1. Copy the following snippet and save it to your current working directory as docker-compose.yaml.

version: '3'

    image: scylladb/scylla-manager
    container_name: scylla-manager
      - scylla-manager-db

    image: scylladb/scylla
    container_name: scylla-manager-db

This file instructs Docker to create two containers, scylla-manager that runs the Scylla Manager Server, and scylla-manager-db that Scylla Manager uses to save its data.

  1. Create and start the containers by running the docker-compose command.

docker-compose up -d
  1. Verify that Scylla Manager started by using the docker-compose logs command.

docker-compose logs -f scylla-manager
  1. Continue to using sctool.

Running with Docker


  1. Start a Scylla container to use as the datastore for Scylla Manager data.

docker run -d --name scylla-manager-db scylladb/scylla

  1. Start Scylla Manager container and link with the scylla-manager-db container.

docker run -d --name scylla-manager --link scylla-manager-db scylladb/scylla-manager

Scylla Manager expects a Scylla node available as scylla-manager-db.


You can give the Scylla container a different name or connect scylla-manager-db container to an already existing container. To do so, use the scylla-manager-db alias in the following link flag: --link some-scylla:scylla-manager-db.

  1. Verify that Scylla Manager stared by using docker logs command.

docker logs -f scylla-manager

Using sctool

Sctool is the Scylla Manager commandline tool. To learn more about it, see sctool reference.

Use docker exec to invoke sctool in a running container.

docker exec -it scylla-manager sctool version

You can also use exec bash and run sctool from within a bash session in the container. This would give you the benefit of bash completion for sctool.

docker exec -it scylla-manager bash
[root@49910e75d06f /]# sctool
cluster  repair   status   task     version
[root@49910e75d06f /]# sctool version

Using a remote database

If you with to persist Scylla Manager data on a remote cluster you need to adjust the configuration options. The configuration file document covers all the Scylla Manager configuration options.


  1. Open editor and create an empty yaml file.

  2. Copy the database and ssl sections from the configuration file document.

  3. Follow the procedure in edit scylla manager configuration and adjust the configuration file.

  4. Optionally, you can remove any comments or not changed lines leaving only relevant changes.

  5. Save the file as scylla-manager-user.yaml in an appropriate location.

  6. Start scylla-manager container with file scylla-manager-user.yaml you created earlier mounted as a volume. Pass it as an additional Docker command (docker run) parameter.

docker run -d --name scylla-manager --link scylla-manager-db scylladb/scylla-manager -c /etc/scylla-manager/scylla-manager-user.yaml

Exposed ports

Scylla Manager exposes the following ports, which are used for integrating Scylla Manager with other services such as Scylla Monitoring.






HTTP server



HTTPS server



Prometheus metrics



Diagnostic port

Exposed volumes

It is often useful to attach host files and directories to the Scylla Manager container. The following volumes are exposed from Scylla Manager.




SSH identity files and SSL key pairs to access the managed clusters


HTTPS certificate



Example for mapping Scylla Manager a volume in docker run command:

docker run -d --name scylla-manager -v certs:/var/lib/scylla-manager/.certs:Z \
-v scylla-manager-user.yaml:/etc/scylla-manager/scylla-manager-user.yaml \
--link scylla-manager-db scylladb/scylla-manager -c /etc/scylla-manager/scylla-manager-user.yaml
