Subject: [Starlingx-discuss] Questions on StarlingX upgrades
[Please note: This e-mail is from an EXTERNAL e-mail address]
Hi,
Looking at the URL below, I had a few questions to understand the overall upgrade strategy.
https://docs.starlingx.io/specs/specs/stx-4.0/approved/starlingx-2007403-platform-upgrades.html
Q1: Can I assume that from R4.0 onwards, the intent is that all future releases will support seamless upgrades for both minor and major versions.
[Bart] You can’t assume this because:
Q2: Is downgrade an explicit non-goal?
[Bart] Correct – starlingx does not support downgrades.
Q3: Any hooks for non-stx applications to backup and restore their state?
[Bart] No
Q4: For a simplex edge node, it involves a N+1 ISO (re)installation. Is a more seamless option on the roadmap
[Bart] No
Q5. For a simplex edge subcloud, possible to orchestrate this from the central cloud?
[Bart] Similar to upgrades, there is an infrastructure for this (i.e. dcmanager upgrade-strategy commands). These commands haven’t been included in the starlingx documentation yet and similar to upgrades, the starlingx community
does not test or support these commands.
Q6: Any non-goals for the seamless upgrade, like say CentOS upgrade?.
[Bart] There has been no decision yet on whether starlingx will be moving to a new version of CentOS or to a different Linux distribution so I can’t comment on this yet.
Any pointers to additional info are very welcome.
Thanks in advance
Pratik
