Your main ROS 2 installation will be your underlay for this tutorial. Understanding of basic terminal commands ( here’s a guide for Linux) It’s also possible to have several layers of underlays and overlays, with each successive overlay using the packages of its parent underlays. Packages in your overlay will override packages in the underlay. Your underlay must contain the dependencies of all the packages in your overlay.

You also have the option of sourcing an “overlay” - a secondary workspace where you can add new packages without interfering with the existing ROS 2 workspace that you’re extending, or “underlay”. This makes ROS 2’s packages available for you to use in that terminal.

However, even a host with more than enough system memory can run Swap Partition Īdministrators can configure sessions to provision with any amount of cpu or memory allocations by editing the in the When using a custom set of Workspaces this storage requirement can vary. Please review the partition layout for the host operating system and ensure this requirement is met. If not enough space is available in Docker’s storage directory (default /var/lib/docker) this can potentially block the entire installation and lead to undesired behavior. Storage requirements are related directly to using the default set of Workspaces optionally downloaded during installation. Provisioned if the minimum resources requirements on the Agent are not met. Workspaces are configured to require 2768MB of memory and 2 cores. Requires additional compute resources as specified in the Workspace configuration. Although the requirements for the Kasm services are quite modest, provisioning each end-user session
