When something is wrong

Start here:

kubectl -n <your-namespace> describe kvsync

The resource reports one reason, and the reasons are kept apart because each sends you somewhere different — the network, the token, your cluster, or the manifest.

Synced

Nothing is wrong: the last sync succeeded.

If values still are not reaching your application, the Secret is current and your pods are not. See Restarting workloads.

Find the reason

You can also paste a reason into the search box: every one of them has a section named after it.
