Prow seems to assign Assignees who are not in OWNERS file

[adelton]

In opendatahub-io/notebooks#587, after adding my LGTM review, openshift-ci (bot) came and "assigned adelton" as Assignee.

I'm not even listed in https://github.com/opendatahub-io/notebooks/blob/main/OWNERS so this is quite surprising and does not seem to match the referenced pull request process at https://github.com/kubernetes/community/blob/master/contributors/guide/owners.md#the-code-review-process.

Should the prow behaviour (perhaps in https://github.com/kubernetes-sigs/prow/tree/main/pkg/plugins/assign) be modified, or should this be brought for clarification to https://github.com/kubernetes/community/?

Right, Prow does that for approvers after they approve a PR. I am actually not sure why it does that :D I'm not sure how your Prow is configured, it can be configured to consider GH approves as Prow approves, which I think is the case here; your review was a GH approve.

For completeness, here's our Prow configs for the repo.

First, https://github.com/openshift/release/tree/master/ci-operator/config/opendatahub-io/notebooks (that's just CI jobs, probably not relevant).

And second, here's our global prow config https://github.com/openshift/release/blob/master/core-services/prow/02_config/_config.yaml and here's the repo specific config https://github.com/openshift/release/blob/master/core-services/prow/02_config/opendatahub-io/notebooks/_prowconfig.yaml and plugin config https://github.com/openshift/release/blob/master/core-services/prow/02_config/opendatahub-io/notebooks/_pluginconfig.yaml
