Kube Reconnect Support not detected on k3s 1.27.2+k3s1

[Klaas-]

Hi,
this is a follow up to ansible/awx#14057 and #683

I am running k3s:

# k3s --version
k3s version v1.27.2+k3s1 (213d7ad4)
go version go1.20.4
# kubectl version -o yaml
clientVersion:
  buildDate: "2023-05-26T22:14:11Z"
  compiler: gc
  gitCommit: 213d7ad499e166290872f51c63d8eaa2f1fe78b3
  gitTreeState: clean
  gitVersion: v1.27.2+k3s1
  goVersion: go1.20.4
  major: "1"
  minor: "27"

kustomizeVersion: v5.0.1
serverVersion:
  buildDate: "2023-05-26T22:14:11Z"

  gitCommit: 213d7ad499e166290872f51c63d8eaa2f1fe78b3

It seems the automatic detection in

receptor/pkg/workceptor/kubernetes.go

Lines 763 to 797 in 4addde8

	func isCompatibleK8S(kw *kubeUnit, versionStr string) bool {
	semver, err := version.ParseSemantic(versionStr)
	if err != nil {
	kw.w.nc.Logger.Warning("could parse Kubernetes server version %s, will not use reconnect support", versionStr)
	return false
	}
	// ignore pre-release in version comparison
	semver = semver.WithPreRelease("")
	// The patch was backported to minor version 23, 24 and 25. We must check z stream
	// based on the minor version
	// if minor version == 24, compare with v1.24.8
	// if minor version == 25, compare with v1.25.4
	// all other minor versions compare with v1.23.14
	var compatibleVer string
	switch semver.Minor() {
	case 24:
	compatibleVer = "v1.24.8"
	case 25:
	compatibleVer = "v1.25.4"
	default:
	compatibleVer = "v1.23.14"
	}
	if semver.AtLeast(version.MustParseSemantic(compatibleVer)) {
	kw.w.nc.Logger.Debug("Kubernetes version %s is at least %s, using reconnect support", semver, compatibleVer)
	return true
	}
	kw.w.nc.Logger.Debug("Kubernetes version %s not at least %s, not using reconnect support", semver, compatibleVer)
	return false
	}

is not working for me. With the latest AWX (22.3.0) I need to set the RECEPTOR_KUBE_SUPPORT_RECONNECT variable manually in my awx spec.

I believe we ended up disabling it by default due to some issues we found with certain k8s environments. @fosterseth @TheRealHaoLiu may be able to provide more details.

Yeah @shanemcd that is correct :) I did not see that change ...

receptor/pkg/workceptor/kubernetes.go

Lines 811 to 813 in 4addde8

	// Can override the detection by setting the RECEPTOR_KUBE_SUPPORT_RECONNECT
	// accepted values: "enabled", "disabled", "auto" with "disabled" being the default
	// all invalid value will assume to be "disabled"

I'll close this :)
