We can’t use skaffold labels to narrow down the list of pods. Signed-off-by: David Gageot <david@gageot.net>

I forgot to add this but if we get an error here, we should add that dirty artifact back to the rebuild list

How would you do that?

You mean I'm rebased on old code?

Yeah just maybe the last commit. I changed this message to the debug and info statement.

Oh, the one I asked you to add? It didn't work well in reality :-) Didn't give enough feedback

use the skaffold labelselector here

I removed it because it wasn't working. What I saw is that when I use a deployment, this deployment gets the labels but not the pods.

I don't think you need to count here. errgroup handles this

The check is to make sure that we try to perform the sync for n files. It has nothing to do with errors. For example, with the code that filters on skaffold labels, it always syncs zero files without giving an error.

Hm, I guess this is a bit tricky. What if we have 2 replicas?

Good point, I'll see how to fix it. Each file should be synced at least once, I guess.

Yeah I think thats the best we can do. But making sure we sync at least once is a good check.

maybe move the len check into perform? a few lines of code saved
Sync files in a sequential manner, it makes the code simpler and anyway, the typical use case will be to sync one file with one pod. Signed-off-by: David Gageot <david@gageot.net>
