Maybe the runner has a different rust version than your local version?

I built locally on x86_64 and aarch64 using rust 1.64.0 and rust 1.61.0 (the version in the Bottlerocket SDK) prior to the rebase, but the weird linking error is still occurring. Since this isn't a high priority I'll drop it into draft and we can poke at it a bit more.

Dropped integ commit (for now).

Is this the linking error you saw? https://github.com/bottlerocket-os/bottlerocket-update-operator/actions/runs/3184235579/jobs/5192405098#step:5:343

Those look to have started a few hours ago 👀

The very same. We merged a couple dependabot updates this morning, but each of those were rebased and retested prior to merge.

Checking to see if bumping the builder image helps.

Temporarily taking caching out of the picture to make sure we aren't running out of disk space.

[jpculp]

Removed testing commit and rebased now that we've cleared the cache.

Deployed the controller / resources and all looks well! Thanks Patrick! 👏🏼
