Is there anything like a `local-exec` in pulumi? I want to run a script after a resource gets updated. Specifically for kubernetes I want to refresh pods in an application namespaces after I update my istio helm chart.

not really, you can `.apply` and run a script in there, but it will get executed every `pulumi up`.

closest thing you can do is to create a custom dynamic provider, which is not super easy

Although not trivial, it's not very difficult either.  The docs here are lacking, but we have a simple example at <https://github.com/pulumi/pulumi/tree/master/tests/integration/explicit_provider>, and docs are available at <https://pulumi.io/reference/pkg/nodejs/@pulumi/pulumi/dynamic/>.

That said:

<@UBAJ7TD53> <@UE1LN7A22> Can you think of a good way of doing this with dynamic providers?

I did not realize that we had docs at all

I am not sure, we thought about having an `Invoke` that lets you do an apply, but that’s not quite the same.

I’m not quite sure how to get the semantics we’d want…

it’s almost like you’d want a kind of “patch” resource.

yeah a patch is exactly right. I’d basically want the effect of running a script like this against a set of namespaces: <https://gist.githubusercontent.com/jmound/ff6fa539385d1a057c82fa9fa739492e/raw/caed819555ecbaa8841c4dce07a367be6f639cc8/refresh.sh>
