Hi @carreter. Thanks for your PR. I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with Once the patch is verified, the new status will be reflected by the I understand the commands that are listed here. DetailsInstructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository. |

@tallclair for visibility. Working on cleaning up the PR to see if we can avoid upgrading the go version and minimize the vendored dependencies! |

Seems like Here are the new packages that are getting pulled into @cheftako Where can I check if these are ok to include? |

Nope, just didn't know about it. Added the -race flag.

thoughts on having just a single renderTemplate where callers pass a file path relative to templates like "agent/service.yaml"?

Sounds like this would be significantly easier to use. Will do!

StatefulSets give the pods a unique identifier we can reach them with.

thoughts on having this return a friendlier type? Current usage always fetches a gauge so we could have this be getMetrics(url, name) (int, error). That would keep the int(connectionsMetric.GetMetric()[0].GetGauge().GetValue()) complexity all in this func

@avrittrohwer Addressed your comments. Working on including this in the GitHub workflows now. |

Excluded the e2e tests from the main test runners (fast-test and test) in the Makefile. Hopefully that fixes this. |

Could you add a short README.md to the e2e directory that goes over what maint_test.go sets up (RBAC and service) and what each specific test is expected to set up?

Done, could you take a look?

nit: I don't see 'KinD' capitalization used on the linked docs, keep it 'kind' for consistency

Hmm, unsure why the tests are failing suddenly. They were working locally. Will do some digging. |

Debuggability is easier if you include the url in with the error.

Again debuggability goes up if you have a reference to relevant request (server pods) with the error.

Added a reference to the label selector being used to discover the pods.

nout found is the obvious error but there could be other reasons we got an error here and we did not check the error type. I would suggest logging it.

%v can mask some interesting errors in a case like this. They may be unequal because they are of different types but their toString method generates the same string. If you believe they should both be ints then it is better to use %d.

Not wrong but its not clear to me why your type converting what appears to be a constant?

Compiler complains that adminPort is an int if I don't conver it.

Had to run
go mod tidyandgo mod vendoralong the way to pull in some dependencies, couldn't figure out how to do this without bumping the go patch version. Hope this is ok, I can try and rework it if not!
