Requirements

Python 3.9+

Pre-requisites

Ensure that following are installed

• virtualenv
• virtualenvwrapper

NOTE: Any of the virtual environment tools ([venv], [virtualenv], or [virtualenvwrapper]) should work.

Installation

Multiple installation options possible. For CF development the recommended method is to install from GitHub MASTER branch:

$ mkvirtualenv fabrictestbed
$ workon fabrictestbed
$ pip install git+https://github.com/fabric-testbed/fabric-cli.git

For inclusion in tools, etc, use PyPi

$ mkvirtualenv fabrictestbed
$ workon fabrictestbed
$ pip install fabrictestbed

Usage (API)

User API supports token and orchestrator commands. Please refer to Jupyter Notebooks here for examples.

Usage (CLI)

Configuration

User CLI expects the user to set following environment variables:

export FABRIC_ORCHESTRATOR_HOST=orchestrator.fabric-testbed.net
export FABRIC_CREDMGR_HOST=cm.fabric-testbed.net
export FABRIC_TOKEN_LOCATION=<location of the token file downloaded from the Portal>
export FABRIC_PROJECT_ID=<Project Id of the project for which resources are being provisioned>

Alternatively, user can pass these as parameters to the commands.

To enable CLI auto-completion, add following line to your ~/.bashrc

eval "$(_FABRIC_CLI_COMPLETE=source_bash fabric-cli)"

Open a new shell to enable completion. Or run the eval command directly in your current shell to enable it temporarily.
