Clara Deploy SDK is being consolidated into Clara Holoscan SDK

More info


This asset requires the Clara Deploy SDK. Follow the instructions on the Clara Ansible page to install the Clara Deploy SDK.


clara is a command line interface for managing and interacting with the Clara Deploy SDK. clara looks for a file named config.yaml in ~/.clara/. You can specify alternate configuration by setting the --config flag and can point to a remote host using the --host flag. You can execute commands with --verbose flag to get command output with additional details.


Clara CLI itself does not have any prerequisites in general, but there can be prerequisites depending on the functionality of CLI you want to use. For example, if you want to create a pipeline, then Clara Platform must be running for the command to function successfully.

Download the latest file and extract the binaries into /usr/bin/

sudo unzip -d /usr/bin/ && sudo chmod 755 /usr/bin/clara*

Generate clara completion script for Bash

sudo bash -c 'clara completion bash > /etc/bash_completion.d/clara-completion.bash' && exec bash

Configure CLI

Configure clara CLI to use your NGC credentials.

clara config --key NGC_API_KEY [--orgteam NGC_ORG/NGC_TEAM] [-y|--yes]

Please note the slash (/) between ORG and TEAM. If --orgteam is not specified, the orgteam defaults to 'nvidia/clara' which points to the publicly available Clara NGC artifacts.

Configuration for Private NGC Org/Team

If the desired Clara component (e.g. platform, render server, etc.) resides in a private org/team within NGC, ensure to run clara config with the correct private --orgteam parameter otherwise Kubernetes will fail to pull the container image for the desired Clara component.


The following table includes short descriptions and the general syntax for all of the clara commands.
