Discussion items

jroot explained that Tamu is working on an implementation timeline for Folio - with a go-live goal of Summer 2020.

Production-ready K8s/Rancher infrastructure needs to be in place by the Fall 2019.
Decided on a stand-alone production K8s cluster for live Folio, with separate clusters for Folio testing, Folio training, other projects and so on.
Using Rancher Server for control plane, RancherOS for the K8s nodes and VMware provisioner.

Anton Emelianov (Deactivated) discussed benefits of CI/CD deployments using K8s and multi-tenants.

Current CI/CD builds from merging on Master, with a single tenant, can create problems - as we've all seen.

Taras Spashchenko outlined the work he has been doing with module schema versioning, upgrading of schemas and data when a back-end module is upgraded and introduces db changes.

Started with simple use-case, changing the structure of the jsonb.
Modules should be in charge of validating and migrating the data between themselves.
Anton Emelianov (Deactivated) relayed that Hongwei Ji suggested for a module to connect to more than one db, so data migrations could happen from one db instance to another in the event of jsonb structure or schema changes.
At present, a back-end storage module cannot connect to more that one db at a time. If this needs to change, a lot of work will have to be done from the development side. Perhaps there could be a single "migration" module that could do this for storage module schema upgrades?
Currently, no way to validate the data from within Postgres once it has been migrated. Maybe there are Postgres extensions for this?

Ian Hardy updated us on the core-team's work with K8s integration with Jenkins CI/CD. There are several tickets in Jira that are being looked at.
