Documentation: ArgoCD apps in any namespace incompatibility

[seanmorton]

For those using Applications in any namespace, the docs should mention that Image Updater is not compatible with any Application resources installed in namespaces other than argocd.

[ElanHasson]

That is unfortunate. This is exactly what I'm doing and I just installed and deployed it :D

This is a dupe of #601 and #612 cover this.

Looks like most recent effort to add support for this was closed: https://github.com/argoproj-labs/argocd-image-updater/pull/672

Could we merge this warning so folks are at least aware? My latest change also adds a brief warning about this to the documentation root.

Thanks @seanmorton @ElanHasson @JStacy86 for the fix and review!

[mcanevet]

Hasn't #687 added the support of Applications in any Namespace?

[chengfang]

@mcanevet thanks for pointing that out. @seanmorton @ElanHasson @JStacy86 could you please verify if the current master branch works for you when using image-updater for apps in any namespace?

I can confirm the image-updater can work with apps in any namespace if you use the APPLICATIONS_API approach. https://github.com/argoproj-labs/argocd-image-updater/issues/601#issuecomment-2249819819
