Kasm Workspaces Requirements

Kasm Workspaces can be installed in a single server or multi server setup.

Operating System

Kasm Services and end user sessions are Docker containers. Access to the Docker registry is required for installation.

Installation is supported on the following operating systems:

Supported Operating Systems

Ubuntu 18.04 / 20.04 / 22.04 (amd64/arm64)

Debian 9 / 10 / 11 (amd64/arm64)

CentOS 7 / 8 / 9 (amd64/arm64)

Oracle Linux 7 / 8 / 9 (amd64/arm64)

Raspberry Pi OS (Debian) 10 / 11 (arm64)



Not all published Workspaces Docker Images are available on all architectures. Please see Default Images for the support matrix.

Resource Requirements

Minimum Requirements


2 cores




50GB (SSD)


Although the requirements for the Kasm services are quite modest, provisioning each end-user session requires additional compute resources as specified in the Workspace configuration. The default Kasm Workspaces are configured to require 2768MB of memory and 2 cores. Sessions will not be provisioned if the minimum resources requirements on the Agent are not met.

Docker and Docker Compose

During the installation, the installer will install known compatible versions of docker and docker compose if the programs do not already exist on the machine. However, if the programs already exist, the installer will not replace them.

It is recommended that you install Kasm on a single-purpose machine and let the installer install the docker and docker compose programs. Below are the minimum requirements.

Minimum Version Requirements


> 18.06

docker compose

> 2.1.1

Run the following commands to check the versions of the programs if installed.

sudo docker --version
sudo docker info | grep "Docker Compose"
