ayounsi added a comment to T324655: Spicerack: don't IRC log start/stop of cookbook.

For the latter part, you can move all the RO pre-requisite checks in the cookbook's init that is run before the START !log, so that the failure will be shown only to you.

FYI, there are outstanding Homer diffs for asw1-eqsin:

-   ge-0/0/16 {

[edit interfaces xe-0/0/19]
-   description cp5029;
+   description "cp5029 {#2022110007}";

Thanks! Not sure why and how these specific ones were not committed. I am guessing these should be safe to merge?

ayounsi added a comment to T313114: Analyze possible bot traffic for frwiki article Cookie (informatique).

@Ladsgroup rate limiting or blocking at the edge should be used only for traffic putting the infrastructure at risk (eg. DDoS). So I don't think we should throttle this.
Such rate limit seems like hiding the problem under the rug, and will become a whack-a-mole game (see. T313114#8316051) adding extra load on SRE and cluttering critical tools.

Some notes/thoughts from a chat with @jbond:

  • Based on P36282 and except Data Engineering,Machine Learning all servers have 1 clear team owner
  • role_contacts has been extremely useful in scheduling maintenance (upgrades, network, etc)
  • In light of https://gerrit.wikimedia.org/r/c/operations/puppet/+/849020 there is a need to assign team owner right during or before provisioning

I agree on the MOTD, it's not a significant change, the last of the 3 options in term of priority/usefulness, but maybe also a low hanging fruit.
Maybe a bit more modern (we can call it the "MOTD of 2022") would be the ability to add it in the Spicerack library. For example if we fetch a host from Netbox using any cookbook and its status is XXX display it.

ayounsi added a comment to T234207: Investigate improvements to how puppet manages network interfaces.

For physical servers we indeed need to keep the whole lifecycle/provisioning process in mind (racking/provisioning/re-imaging) etc.
Which means being able to map the real world interface to the logical one, from previous conversations it's one of the tricky points (eg. where there are multiple cards with multiple NICs).
Having a first iteration with VMs only could allow to test the software side mechanisms without having to solve the "physical" part.
I also agree with @cmooney ideal end state.
