pod affinity/anti affinity is not supported?

[ezlo-eugenek]

I've spec in statefulset:
spec:
affinity:
podAntiAffinity:
requiredDuringSchedulingIgnoredDuringExecution:
- labelSelector:
matchExpressions:
- key: "service"
operator: In
values:
- kafka
topologyKey: "kubernetes.io/hostname"
podAffinity:
preferredDuringSchedulingIgnoredDuringExecution:
- weight: 1
podAffinityTerm:
labelSelector:
matchExpressions:
- key: "app"
operator: In
values:
- zk

And I get such error:
2:56PM Warn | excluding attribute [kubernetes_stateful_set.spec.template.spec.affinity.pod_affinity.preferred_during_scheduling_ignored_during_execution.pod_affinity_term.label_selector.match_expression] not found in Terraform schema field=StatefulSet.Spec.Template.Spec.Affinity.PodAffinity.PreferredDuringSchedulingIgnoredDuringExecution.PodAffinityTerm.LabelSelector.MatchExpressions name=kafka type=kubernetes_stateful_set

Noticed this too. I have the latest version.

What caught my eye is the reference to the "label_selector.match_expression" (note the lack of s at the end of expression), even though in my K8s file I definitely have it.

I tried searching the repository if there's something specific handling this case but this seems to be part of an automated schema translation, so that would require more code-reading I guess 🙂

I have the same issue

using:

> k2tf --version
k2tf version: dev

testing:
https://raw.githubusercontent.com/GoogleCloudPlatform/container-engine-accelerators/master/nvidia-driver-installer/cos/daemonset-preloaded.yaml

output :

        affinity {
          node_affinity {
            required_during_scheduling_ignored_during_execution {
              node_selector_term {}
            }
          }
        }

instead :

        affinity {
          node_affinity {
            required_during_scheduling_ignored_during_execution {
              node_selector_term {
                match_expressions {
                  key = "cloud.google.com/gke-accelerator"
                  operator = "Exists"
                }
              }
            }
          }
        }

$ k2tf --version
k2tf version: 0.5.0

ref: https://github.com/sl1pm4t/k2tf/blob/v0.5.0/hcl_writer.go#L213

if !includeUnsupported && current.unsupported {
// don't append this block or child blocks
w.warn().
	Str("field", current.FullFieldName()).
	Msgf("excluding attribute [%s] not found in Terraform schema", current.FullSchemaName())

}

There's a flag --include-unsupported, and as mentioned by others the match_expressions seems to be the cause as it's converted to match_expression

my scripts use

sed -e 's/match_expression/match_expressions/g'
