@jbartosik something like that?
Let me know and I'll add some test coverage and docs.

@jbartosik can check and tell me what's missing, please?

Thanks. Mostly looking good, I made a few, hopefully small suggestions.

Please ping me when I should take another look

Thanks @jbartosik I've missed that... does my change suit you?

jbartosik

I think we're getting close. I left a few comments but I saw just some small stuff to change.

-			targetSelectorFetcher.EXPECT().Fetch(vpa).Return(tc.selector, tc.fetchSelectorError)
+			if !tc.expectNoVpaFetch {


I'd strongly prefer to avoid having variables with negations in names. So expectVpaFetch instead of expectNoVpaFetch. It's easier to read & reason about variables that say something positive than about negated ones. I know it's some more writing for this commit but I think making code easier to maintain is worth it.

@jbartosik thanks for your help, I think we're good to go :)

jbartosik

Looks good to me. But I don't want to merge it for a while more. I want to finish releasing VPA 0.12.0 (I think code is good but e2e tests are timing out) before merging any changes to VPA that are not necessary for the release.

So

/hold

for now. I plan to unhold and merge after I publish the release

@jbartosik can you also change the "Draft" status of the PR? I cannot do it, strangely :(

/lgtm

jbartosik · 2022-09-26T13:53:00Z

@matthyx can you add some documentation on running multiple recommenders.

I think it can be quite simple, something like:

a yaml with recommender with different cpu percentile and name in flag
a short .md file pointing to the yaml and highlighting the flags and what they do.
