Proposal for a single rucio chart with complete reproducible deployment of rucio

[volodymyrss]

Related to #228

We decided to split this PR into multiple smaller PRs. This PR will be just a reordering of charts.

Original comment below.

The principle agreed with @bari12 on Rucio-Dirac workshop, but not the technical details of the chart implementation.

In CTAO we made a chart of our Bulk Data Management System (BDMS) including as subcharts rucio charts, optional dependencies charts, and adding jobs for bootstrap and configure. See a talk.

This would require several changes ported to upstream rucio chart:

• put existing rucio-server, rucio-demons, etc charts to be subcharts of rucio chart.
• add bootstrap and configure jobs
• add certificate generation/issuer/manager subchart with options:
  • self-signed CA
  • admin-provider certificates
  • letsencrypt (where possible)
  • IAM x509 certificates (RCAuth-based)
• appropriate documentation

Please let me know if this set of changes makes sense!
The PR is started as a draft, just starting to move.

Hey @volodymyrss, I am not able to access the link to the talk ( probably due to access restrictions). Could you please highlight what are the global variables you'd use that are accessible to all the sub-charts?

Hi @maany , thanks for having a look on this draft proposal! Please see updated link, it should work.

Could you please highlight what are the global variables you'd use that are accessible to all the sub-charts?

For example, database configuration and rucio version.

Please have a look here of our integrated chart we use : https://gitlab.cta-observatory.org/cta-computing/dpps/bdms/bdms/-/tree/main/chart (this one with test values)

We will merge this branch into 228-unified-rucio-helm-charts in order to test.
