What is Kasm Workspaces?

Kasm Workspaces is a docker container streaming platform that enables you to deliver browser-based access to desktops, applications, and web services. Kasm uses a modern DevOps approach for programmatic delivery of services via Containerized Desktop Infrastructure (CDI) technology to create on-demand, disposable, docker containers that are accessible via web browser. -https://github.com/kasmtech/workspaces-core-images

Installing Docker

1. Log into the Linux based device
2. Run the following commands in the terminal

# install prerequisites
sudo apt install apt‐transport‐https ca‐certificates curl software‐properties‐common gnupg‐agent ‐y
# add docker gpg key
curl ‐fsSL https://download.docker.com/linux/$(awk ‐F'=' '/^ID=/{ print $NF }' /etc/os‐release)/gpg | sudo apt‐key add ‐
# add docker software repository
sudo add‐apt‐repository "deb [arch=$(dpkg ‐‐print‐architecture)] https://download.docker.com/linux/$(awk ‐F'=' '/^ID=/{ print $NF }' /etc/os‐release) $(lsb_release ‐cs) stable"
# install docker
sudo apt install docker‐ce docker‐compose containerd.io ‐y
# enable and start docker service
sudo systemctl enable docker && sudo systemctl start docker
# add the current user to the docker group
sudo usermod ‐aG docker $USER
# reauthenticate for the new group membership to take effect
su ‐ $USER

Deploying Kasm Workspaces [Simple Method]

This is the recommended installation method, but requires the most disk space. I choose to be more selective about the Kasm images running, so I use the second installation option outlined later on.

1. Continue with the following commands in a terminal window

# change directory to /tmp
cd /tmp
# download the latest kasm workspaces release
curl ‐O https://kasm‐static‐content.s3.amazonaws.com/kasm_release_1.11.0.18142e.tar.gz
# extract the downloaded tar.gz
tar ‐xf kasm_release*.tar.gz
# execute the installation script
sudo bash kasm_release/install.sh

2. Take note of the credentials displayed in the output
3. Open a web browser and navigate to https://DNSorIP
4. Log in using username admin@kasm.local and the password found in the installation output

Deploying Kasm Workspaces [Selective Method]

This method can use far less disk space, but requires more time and setup to add Kasm images manually. I only add the Kasm images I use regularly.

1. Continue with the following commands in a terminal window

# change directory to /tmp
cd /tmp
# download the latest kasm workspaces release
curl ‐O https://kasm‐static‐content.s3.amazonaws.com/kasm_release_1.11.0.18142e.tar.gz
# extract the downloaded tar.gz
tar ‐xf kasm_release*.tar.gz
# execute the installation script
# installing only the core images
# and setting a custom https port
sudo bash kasm_release/install.sh ‐I ‐L 8443

2. Take note of the credentials displayed in the output
3. Open a web browser and navigate to https://DNSorIP:8443
4. Log in using username admin@kasm.local and the password found in the installation output

Adding Kasm Desktop/Application Images

1. Navigate to https://hub.docker.com/u/kasmweb to view the available Kasm images
