iReceptorPlus for Tapis

Scripts and JSON definitions for deploying iReceptorPlus systems and apps in Tapis.

Tapis (formerly called Agave) is an open source, science-as-a-service API platform.

Contents

• systems: JSON definitions for execution/storage systems.

• apps: JSON definitions and application wrapper for tools.

Using the docker image

This repository has a corresponding docker image which can be used to access Tapis. The image contains the Tapis command-line interface (CLI), agavepy python library, and other useful tools. Immune repertoire analysis tools do not reside within this image, as they will be provided in separate images that can be run on HPC.

Requirements

To use the docker image, you need these requirements:

• Docker Desktop installed on your computer.

• VDJServer user account.

Pull down the latest image from docker hub.

docker pull ireceptorplus/tapis

Initialize Tapis CLI and User Authentication

When you initialize Tapis and login with your VDJServer user account, Tapis returns an authentication token for all subsequence requests. This token is managed for you and is saved to disk. However, by default, files created in the docker container are deleted when exiting the container. To avoid having to initialize Tapis every time you use the docker image, we mount a local directory into the docker container where the files are saved.

# Create a local directory to hold Tapis initialization and token data
mkdir tapis-token

Run a bash shell and initialize Tapis. The initialization will ask a few questions. When it asks for the tenant name, pick vdjserver.org. It will then ask for your VDJServer username and password for login. The prompts for container registry access and git server access can be left blank or left as the provided defaults.

docker run -v $PWD/tapis-token:/root/.agave -it ireceptorplus/tapis bash

tapis auth init

With Tapis initialized, you can now try some commands:

# help for the Tapis CLI
tapis --help

# show your authentication token
tapis auth show

# refresh your authentication token when it expires
tapis auth tokens refresh

# create a new authentication token (requires password)
tapis auth tokens create

# list of systems available
tapis systems list

# list of apps available
tapis apps list

# list files in the irplus directory (you need permission to view)
tapis files list agave://data.vdjserver.org/irplus

App Development

While the docker image provides a copy of this repository, any changes you make to files within the image might be lost, so clone this repository to your local system and mount it in the docker container for doing development. You will generally want to perform git commands and use an editor outside of docker.

# clone the repository
git clone https://github.com/ireceptor-plus/tapis.git
cd tapis
git submodule update --init --recursive

# run docker with both your tapis token and source directories mounted
docker run -v $PWD/tapis-token:/root/.agave -v $PWD/tapis:/work -it ireceptorplus/tapis bash

# access local app development
cd /work

Hackathon Notes

The hackathon of Sep 2-4 provided a tutorial presentation and hands-on session for app development. Here are some notes and a Jupyter notebook put together by Marco Amaro Oliveira.
