phyapps-cloud

Cloud computing platform for software development for physics applications on accelerators.

Overview

• After login this platform, each user can create/update their own Jupyter-Notebook service with physics applications development environment included, w/ or w/o virtual accelerator running or not.

• Each user has the private space to work with, e.g., the virtual accelerator which the user is manipulating will not affect other users.

• Each user has the flexibility to adjust their own service settings, e.g., start/stop/pause/resume virtual accelerator with different LINAC sections.

• The Jupyter-Notebook can only be accessed by the user who created.

• Within Jupyter-Notebook, user can do anything based on the provisioned Python packages.

• The extensibility to support more services, currently, only supports VA with FRIB LINAC configurations.

• Available services:

  • phyapps-va
  • phyapps-nb

Prerequisites

• Install Docker & Pull Docker images:

  docker pull tonyzhang/phyapps:<tagname>

  where, <tagname> could be nb, va.

• Initialize Swarm environment for deployment: docker swarm init .

Deployment

1. Clone this repository: git clone https://github.com/archman/phyapps-cloud.git, locate Makefile.

2. Set environmental variables in terminal or change in-place:

   • SRV_IP: IP address of the workstation as the swarm server
   • TOKEN: secret string for authentication
   • MYSQL_ROOT_PASSWORD: root password for MySQL service
   • DATABASE_NAME: database name for phyapps-gateway service
   • DATABASE_USER: database user account
   • DATABASE_PASS: DATABASE_USER's password

3. Type make deploy to deploy.

4. Type make stop to stop.

5. The URL should be https://<SRV_IP>:8000

Here is an example to deploy the phyapps_cloud stack on the workstation with serving IP of 10.20.30.40, with default configurations of MySQL service.

SRV_IP=10.20.30.40 TOKEN=6eec0c438f2e59711a1838d1207e1c make deploy

It is recommended to redirect the output to a file, e.g. make deploy 2>&1 | tee log

6. Only do once Database configuration: https://<SRV_IP>:8000/init, first initialize the database and then set up administrator account.
