Can flux kustomization dry-run be performed in cmdline?

[maplewf]

Hi,

As I know, flux kustomization controller will execute dry-run before really applying manifests, this is very nice since it can prevent malformed configuration is applied. But I wonder if this dry-run check can be executed with cmdline, since I want to integrate this great check with my git source code workflow.

I know there is flux build kustomization for building/checking manifest against with cluster or offline, but the check result of this cmdline doesn't reach my expectation. For example, if I add a manifest with kind A, but CRD for A is missing from cluster, then dry-run from flux kustomization controller can detect it but flux build kustomization can't.

So is there way for us to do same check in source code as flux kustomization controller dry-run did? Thanks

Yes the dry-run is implemented in the CLI with flux diff kustomization which runs against the live cluster without modifying its state, the diff is what the controller does before the actual server-side apply.
