Kubeping on Kubernetes 1.17

[mauriciomag]

Hi, I tested Wildfly / Kubeping on Kubernetes 1.17 and got the following issue:

12:39:26,943 WARN  [org.jgroups.protocols.kubernetes.KUBE_PING] (thread-10,kubernetes,wildfly-deployment-f8d595bb5-s6ljn)
 failed getting JSON response from Kubernetes Client[masterUrl=https://kubernetes.default.svc:443/api/v1, headers={Authorization=#MASKED:999#}, 
connectTimeout=5000, readTimeout=30000, operationAttempts=3, operationSleep=1000, 
streamProvider=org.jgroups.protocols.kubernetes.stream.InsecureStreamProvider@39127235] for cluster [kubernetes],
 namespace [labs], labels [app=wildfly]; encountered [java.lang.Exception: 3 attempt(s) with a 1000ms sleep to execute 
[OpenStream] failed. Last failure was [javax.net.ssl.SSLHandshakeException: extension (5) should not be presented in certificate_request]] 

and I found the following threads:

• https://bugs.openjdk.java.net/browse/JDK-8234949
• https://github.com/golang/go/issues/35722

After that I tested it on Kubernetes 1.16 and it worked correctly.

My repo: GitHub - msmagnanijr/wildfly18-kubeping

I wonder if anyone has seen this before.

Best,

I believe this is a JDK issue, so you need to wait and then use a JDK version with the fix, i.e. JDK 11.0.7 or higher or JDK 14 or higher.
