Tapis CLI

Tapis CLI is a human-friendly, scriptable command line interface, implemented in Python, that helps scientists and engineers build and manage scalable computational and data science workflow projects using the Tapis platform. It is a replacement for a pure-Bash CLI environment known as agave-cli that we hope brings you new features, better reliability, and dramatically enhanced productivity.

Tapis CLI provides a unified interface to multiple web service APIs, allowing them to be easily orchestrated and composed into higher-order constructs combining HPC, data management, cloud computing, and other aspects of computing.

Installation

The latest stable release of Tapis CLI is available on PyPi and is the recommended way for most people to install it.

$ pip install tapis-cli

Stable but possibly as-yet unreleased updates are available via the main branch of the Tapis CLI GitHub repository.

$ git clone https://github.com/TACC-Cloud/tapis-cli.git
$ cd tapis-cli
$ pip install --user .

Container Image

As an alternative to local installation, the CLI is available as a public Docker image tacc/tapis-cli:latest on DockerHub:

docker run --rm -it -v ${PWD}:/work -v ${HOME}/.agave:/root/.agave \
    tacc/tapis-cli:latest bash

Initialize a Session

You must set up a Tapis session on each host where you will use Tapis CLI. This is a scripted process implemented by tapis auth init. Here's an example:

$ tapis auth init

Use of Tapis requires acceptance of the TACC Acceptable Use Policy,
which can be found at https://portal.tacc.utexas.edu/tacc-usage-policy
