LSobanski moved T378769: scap / puppet dependency issue on reimaged phabricator hosts from Incoming to Backlog on the Collaboration-Services board.
Fri, Aug 14, 3:15 PM · Release-Engineering-Team, Collaboration-Services, Scap
LSobanski placed T378769: scap / puppet dependency issue on reimaged phabricator hosts up for grabs.

Confirmed with @Arnoldokoth that this is still a problem. I think there's more value in pursuing single-method deployment or migration to Docker than there is in fixing this, leaving it around as Low priority.

LSobanski added a comment to T425441: gitlab behind CDN.

Calling this out explicitly so it doesn't get lost in the list of changes: @ABran-WMF disabled the legacy nftables throttling on the replicas as it was causing envoy timeouts, see https://gerrit.wikimedia.org/r/c/operations/puppet/+/1325454.

LSobanski changed the status of T431003: zuul-client encrypt fails to retrieve public key from Open to Stalled.

Re-enabled puppet on zuul1001 where I had applied gerrit:1314120 to showcase it as a possible fix.

Antoine has indicated he wants to keep following the approach of upstream though, which uses RewriteRules rather than pure ProxyPass config. Afaict using rewrite rules caused the problem described in this ticket though.

Unless I misunderstood we are therefore just waiting for a fix in upstream.

Not entirely sure if this is blocking switch to new zuul or just a nice to have.
