Notes

Rationale

  • Open edX Architecture moving from a centralized model to a decentralized model.

    • Similarly for the edX SRE team

  • Many of our teams own backend and frontend components, within and outside of the monolith

    • Each may want to do things differently - their pace, their testing, their definition of done, etc.

  • Hence, our centralized Configuration repo is problematic and bottlenecked

  • Changes to repo

    • Need to work with last 2 old releases, multiple OSes, multiple environments (sandboxes, etc).

      • Only the latest community release is supported, but some internal edX uses use older releases.

    • In the past, have taken OSPR changes but haven’t tested ourselves, but has added to our maintenance burden

    • Also realized that any change in configuration needed a long deprecation process

  • Configuration state in production

    • Many teams just couldn’t figure out what the state of a configuration was in production or in other environments

    • It was difficult to parse this from the code since the settings were tangled in Ansible files, YAML files, etc, etc.

    • So… moved to detangling the settings (De-DRY)

...

  • OEP-45 follow-up

    • NGinx configuration - what are the plans for this?

      • Would this be with sample Helm charts?

      • edX would be using nginx ingress

      • Possible Options

        • A: Provide an example chart

        • B: Provide an open chart that edX also consumes

  • Myth: Entire configuration for an IDA can be stored in a given repo

    • Example: Authentication is coupled across repos

      • operation was in the Ansible playbooks

    • Note: decentralized devstack has a similar issue

  • In addition to Helmcharts, you are also using Consul Templates to pull in secrets from Vault?

    • Yes, those go into as values in the Helmcharts.

  • Timeline for deprecation?

    • Let’s discuss this together and work together on accelerating and converging on this effort

  • Currently evaluating Tutor as a community-supported deployment mechanism

    Sane defaults

    • Usual questions: Testing, Devstack, Docker files, etc.

    • It seems similar problems underneath, no?

    • For example, should Tutor be the next Devstack?

      • Tutor - make it easy to install

        • Devstack is trying to address the same issue

    • Currently, not a hard blocker since we are pushing images in our current Devstack.

Open Questions

    • edX Architecture team is the newly designated “owner” for Devstack and plans to look into addressing short-term issues as well as long-term plans. Nim will ask the team to watch the recording from today and follow-up with this group in order to converge paths.
