Once you have access to your Kubernetes cluster, you can deploy Rucio for a given overlay (found in overlays/[dev,prod,int,dune,etc...]) using the Makefile found in that overlays/<experiment> directory.
make apply
This will run multiple steps, downloading Secrets from Vault, building K8s resourece manifests with Helm templates, ending by using Kustomize to create or update the Rucio application resources.
This framework uses kustomize to allow modification of Helm template outputs from the official Rucio Helm chart. This is used in particular to patch the environment of containers such that they are configured to have the database connection string passed in via the value of a Secret. This allows us to keep the Kubernetes resource manifests generated by the Helm templates under version control, without exposing a base64 encoded password as compared with a --values injection to the Helm template process.
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 is run and then loaded into the cluster via SecretGenerator definitions in the kustomization.yaml files.
The hostcert.pem, hostkey.pem, ca.pem, and db-connstr files should be placed in <rucio-ams>/overlays/<experiment>/rucio/etc/.secrets/
This directory is setup in .gitignore to not be commited for obvious reasons.
These secrets should optimally be downloaded from Vault at deployment time for centrailized distribution, rather than being stored locally.
For selection of a policy package, simply add __init.py__, permission.py, and schema.py to
<rucio-ams>/overlays/<experiment>/etc/policy-package. No other configuration is required, as the files are
mounted as a secret. All policy packages will be referred to in the containers/config files as "fermilab",
regardless of the experiment-specific policy package implementation files mounted.
