I’m getting a list of namespaces for my EKS cluster and for each I’m calling:

namespace, err := corev1.NewNamespace(ctx, name, ...)
	if err != nil {
		return nil, nil
	}

to create them. But there are some exceptions, like

kube-system

, which is already in EKS. Pulumi is failing with:

namespaces "kube-system" already exists

because obviously this namespace is already there. I tried to catch error message like

if err.Error() == "…"

or/and

return nil, nil

. But it’s still the same error message. Is there any way to workaround this?

I usually try to lookup the resource and put a conditional import if I want to go this route. Error handling in a more “idiomatic go” way doesn’t seem to work
