rubin-rucio-deploy

Deployment framework for Rubin USDF Rucio.

This project requires a Kubernetes cluster with permissions to run operators as needed. Once you have access to your Kubernetes cluster, you can deploy Rucio for a given overlay (found in overlays/[dev,prod]) using the Makefile found there with (most simply)

make apply

This will run multiple steps, downloading Secrets from Vault and ending up using Kustomize to create or update rucio, rucio-db, kafka, and other namespaces, as well as the resources (servers/daemons) to run a Rucio application in those namespaces. Rucio application containers will run in the rucio namespace, while the rucio-db namespace is used for a CloudNativePG operator managed PostgreSQL database. The kafka namespace contains a Strimzi-deployed Kafka cluster definition to serve as the transfer messaging portion of the Rubin Data Backbone.

This framework uses kustomize to allow modification of Helm template outputs from the official Rucio Helm chart. Secrets stored in Vault are downloaded by the controlling Makefile for a given overlay. Secrets are then created in the cluster and provided to the Rucio application through a combination of Kustomize creating the Secret objects, and the Rucio Helm chart values determining which containers/daemons those secrets are mounted to.

Before deploying Rucio, the secrets and credentials needed for the application will need to be pushed to Vault. Vault-resident secrets will be downloaded when make apply in the controlling Makefile for a given overlay is run.

If you update the values-*.yaml files, be sure to also update the rucio helm templates with the following Makefile command for your chosen overlay:

make rucio  # update from upstream helm charts
