# project information project_name: kasm project_url: "https://www.kasmweb.com/?utm_campaign=LinuxServer&utm_source=listing" project_logo: "https://kasm-ci.s3.amazonaws.com/kasm_wide.png" project_blurb: | [{{ project_name|capitalize }}]({{ project_url }}) Workspaces is a docker container streaming platform for delivering browser-based access to desktops, applications, and web services. Kasm uses devops-enabled Containerized Desktop Infrastructure (CDI) to create on-demand, disposable, docker containers that are accessible via web browser. Example use-cases include Remote Browser Isolation (RBI), Data Loss Prevention (DLP), Desktop as a Service (DaaS), Secure Remote Access Services (RAS), and Open Source Intelligence (OSINT) collections. The rendering of the graphical-based containers is powered by the open-source project [KasmVNC](https://www.kasmweb.com/kasmvnc.html?utm_campaign=LinuxServer&utm_source=kasmvnc). project_lsio_github_repo_url: "https://github.com/linuxserver/docker-{{ project_name }}" project_categories: "Remote Desktop,Business" # supported architectures available_architectures: - {arch: "{{ arch_x86_64 }}", tag: "amd64-latest"} - {arch: "{{ arch_arm64 }}", tag: "arm64v8-latest"} # development version development_versions: false # container parameters common_param_env_vars_enabled: false param_container_name: "{{ project_name }}" param_usage_include_net: false param_usage_include_env: true param_env_vars: - {env_var: "KASM_PORT", env_value: "443", desc: "Specify the port you bind to the outside for Kasm Workspaces."} param_usage_include_vols: true param_volumes: - {vol_path: "/opt", vol_host_path: "/path/to/{{ project_name }}/data", desc: "Docker and installation storage."} param_usage_include_ports: true param_ports: - {external_port: "3000", internal_port: "3000", port_desc: "Kasm Installation wizard.

This container also requires an initial setup that runs on port 3000. **Unlike other containers the web interface port (default 443) needs to be set for the env variable `KASM_PORT` and both the inside and outside port IE for 4443 `KASM_PORT=4443` `-p 4443:4443`** **Unraid users due to the DinD storage layer `/opt/` should be mounted directly to a disk IE `/mnt/disk1/appdata/path` or optimally with a cache disk at `/mnt/cache/appdata/path`** Access the installation wizard at https://`your ip`:3000 and follow the instructions there. Once setup is complete access https://`your ip`:443 and login with the credentials you entered during setup. The default users are: * admin@kasm.local * user@kasm.local Currently Synology systems are not supported due to them blocking CPU scheduling in their Kernel. ### Updating KASM In order to update kasm, first make sure you are using the latest docker image, and then perform the in app update in the admin panel. Docker image update and recreation of container alone won't update kasm. ### GPU Support During installation an option will be presented to force all Workspace containers to mount in and use a specific GPU. If using an NVIDIA GPU you will need to pass `-e NVIDIA_VISIBLE_DEVICES=all` or `--gpus all` and have the [NVIDIA Container Runtime](https://github.com/NVIDIA/nvidia-container-runtime) installed on the host. Also if using NVIDIA, Kasm Workspaces has [native NVIDIA support](https://www.kasmweb.com/docs/latest/how_to/gpu.html) so you can optionally opt to simply use that instead of he manual override during installation. ### Gamepad support In order to properly create virtual Gamepads you will need to mount from your host `/dev/input` and `/run/udev/data`. Please see [HERE](https://www.kasmweb.com/docs/develop/guide/gamepad_passthrough.html) for instructions on enabling gamepad support. ### Persistant profiles In order to use persistant profiles in Workspaces you will need to mount in a folder to use from your host to `/profiles`. From there when configuring a workspace you can set the `Persistant Profile Path` to IE `/profiles/ubuntu-focal/{username}/`, more infomation can be found [HERE](https://www.kasmweb.com/docs/latest/how_to/persistent_profiles.html). ### Reverse proxy A sample for [SWAG](https://github.com/linuxserver/docker-swag) can be found [here](https://raw.githubusercontent.com/linuxserver/reverse-proxy-confs/master/kasm.subdomain.conf.sample). Post installation you will need to modify the "Proxy Port" setting under the default zone to 0 as outlined [here](https://www.kasmweb.com/docs/latest/how_to/reverse_proxy.html#update-zones) to launch Workspaces sessions. # init diagram init_diagram: | "kasm:latest": { docker-mods base { fix-attr +\nlegacy cont-init } docker-mods -> base legacy-services custom services init-services -> legacy-services init-services -> custom services custom services -> legacy-services legacy-services -> ci-service-check init-migrations -> init-adduser init-os-end -> init-config init-config -> init-config-end init-config-kasm -> init-config-end init-crontab-config -> init-config-end init-config -> init-config-kasm init-config -> init-crontab-config init-mods-end -> init-custom-files init-adduser -> init-device-perms base -> init-envfile base -> init-migrations init-config-end -> init-mods init-mods-package-install -> init-mods-end init-mods -> init-mods-package-install init-adduser -> init-os-end init-device-perms -> init-os-end init-envfile -> init-os-end init-custom-files -> init-services init-services -> svc-cron svc-cron -> legacy-services init-config-kasm -> svc-docker init-services -> svc-docker svc-docker -> legacy-services init-config-kasm -> svc-kasm-wizard init-services -> svc-kasm-wizard svc-kasm-wizard -> legacy-services } Base Images: { "baseimage-ubuntu:noble" } "kasm:latest" <- Base Images # changelog changelogs: - {date: "13.11.25:", desc: "Pin docker to v28 to avoid API deprecation issues."} - {date: "22.10.25:", desc: "Update for 1.18.0 release."} - {date: "08.06.25:", desc: "Deprecate develop branch."} - {date: "03.06.25:", desc: "Rebase to Ubuntu Noble.
