Description

I am trying to use CIS CRD to create kubernetets dashboard. I think it was working on CIS 2.3.x, but when I upgraded to 2.7.1, it stoped working with 422 declarationFullId error.

Steps To Reproduce

apiVersion: cis.f5.com/v1
kind: TLSProfile
metadata:
  labels:
    f5cr: "true"
  name: kubernetes-dashboard-certs
  namespace: kubernetes-dashboard
spec:
  hosts:
    - example.com
  tls:
    clientSSL: kubernetes-dashboard-certs
    reference: secret
    termination: edge

---
apiVersion: cis.f5.com/v1
kind: VirtualServer
metadata:
  labels:
    f5cr: "true"
  name: k8s-dashboard
  namespace: kubernetes-dashboard
spec:
  host: example.com
  pools:
    - monitor:
        interval: 15
        recv: ""
        send: "GET /oauth/health"
        timeout: 5
        type: http
    - path: /
      service: kubernetes-dashboard-proxy
      servicePort: 3000
  tlsProfileName: kubernetes-dashboard-certs
  httpTraffic: redirect
  virtualServerAddress: x.x.x.x
  virtualServerHTTPSPort: 443
  #virtualServerName: k8s-dashboard

Expected Result

The virtualserver, and pools should be created on BigIP.

Actual Result

The virtual server and pool are not created due to 422 error.

Diagnostic Information

It doesn't matter if I use virtualServerName: k8s-dashboard or not, the controller seems generate a name _0_kubernetes_dashboard that is not in any of the kubernetes VirtualServer configuration spec.

Observations (if any)

See the partial controller logs. Not sure if gtm has anything to do with it - we are using LTM, not GTM.

[mdditt2000]

Looking into this.

• GTM on BIG-IP is fine. no issues
• CRD names are fine. no issues
• Hostname is fine, no issues
• Namespace kubernetes-dashboard is fine, no issues
• Port 3000 no issues creating VS
• Redirect is fine
• Service name is fine..

i dont see the same issue.

Please use my CRDs at https://github.com/mdditt2000/kubernetes-1-19/tree/master/cis%202.8/github/2286/split/working

Please use CIS test image located here https://github.com/mdditt2000/kubernetes-1-19/blob/master/cis%202.8/github/2286/f5-bigip-ctlr-deployment.yaml

This should work fine!!

@mdditt2000

Compared with your dashboard CRD, I found a syntax error in my pools definition, , although it's not reported in the deployment:

- path: /
      service: kubernetes-dashboard-proxy
      servicePort: 3000

The dash in path is causing propertyName generation error, I think. path should be at the same level with monitor. Removing the leading dash AND using the new image 2.8.0 works!

I retested cis 2.7.1, it works too! Should I stay on 2.8.0 (not released yet), or revert to 2.7.1?

Thanks! Great help!

[mdditt2000]

@xueshanf do you have 30 min to chat? I am based in San Jose CA. Would like to understand your use-case and chat about 2.7x verse 2.8

Recommend validate with the latest CIS release.
