This commit will introduce a simple retry mechanism that makes the
Kubernetes provider more tolerant to misordered resource creation, as is
particularly common in Helm and Kubernetes YAML. For example, if
Kubernetes YAML specifies to create a
Pod
before theNamespace
itresides in, it is likely this will cause
pulumi up
to fail. Anotherexample is creating
CustomResoruces
before an operator or controller hasthe opportunity to register the relevant
CustomResourceDefinition
s.We ameliorate this bug by retrying creation REST calls that fail, with
some backoff, and some maximum retry threshold. The effects of this are:
dependencies between resources.
CRDs, custom controllers, and custom operators, since the retry logic
can stand in for all but the most complex of these (which would still
require await logic).
This commmit represents major progress towards #240, and should (we
believe) fix #239.
