Abstract

This page describes the configuration files required by the production deployment of the ChRIS backend services. Those files can contain secret variables such as API keys and authentication passwords as well as other configuration variables.

Currently required files

  • .chris.env
  • .chris_db.env
  • .chris_store.env
  • .chris_store_db.env
  • .pfcon.env
  • .pman.env
  • .swift_service.env

Those files should be copied within a secrets folder created under the appropriate path inside the source of the repo, like:

git clone https://github.com/FNNDSC/ChRIS_ultron_backend
cd ChRIS_ultron_backend
mkdir swarm/prod_deployments/secrets

Reverse Proxy Settings

If the app is behind a reverse-proxy to enable HTTPS upgrade, in .chris.env and .chris_store.env set

DJANGO_SECURE_PROXY_SSL_HEADER=HTTP_X_FORWARDED_PROTO,https
DJANGO_USE_X_FORWARDED_HOST=true

Automatic Script

If you're using ./deploy.sh and want things to "just work," use this script to set random values to all the required variables.

#!/bin/bash
# purpose: set up swarm/prod_deployments/secrets/*.env

DJANGO_CORS_ORIGIN_WHITELIST=${DJANGO_CORS_ORIGIN_WHITELIST:-"babymri.org"}

# Create a random mixed-case alphanumieric string of given length (default 60)
function generate_password () {
  head /dev/urandom | tr -dc A-Za-z0-9 | head -c "${1:-60}"
}
