When an ImageUpdateAutomation is specified in namespace A, the image-automation controller will select imagepolicy setters which match the namespace of the ImageUpdateAutomation object (A), and silently skip any
{"$imagepolicy":"nota:whatever"}
commentsThis caused me some confusion for a while - in our case we have a single
flux-system
ImageUpdateAutomation resource in our bootstrapped flux repositories, and because this wasn't explicitly mentioned at this point in the docs, I assumed it would make more sense to put the ImagePolicy and ImageRepository resources in the namespaces of their relevant deployments, rather than in theflux-system
one, however these aren't found by the image-automation setters.The language could be improved, but I was struggling to word the explanation.
