.NET Core: GKE Autonomous Operator: UnsupportedAddressFamily


#1

I am port forwarding with my cluster using cb-cluster-member-0000 in GKE with the command
$ kubectl port-forward cb-cluster-member-0000 8091:8091
and am able to access the web UI and verify the buckets I’m requesting exist.

Whenever I attempt any operation on my GKE cluster, I get:

Bootstrapping failed from http://localhost:8091/pools: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Couchbase.Utils.UnsupportedAddressFamilyException: http://cb-cluster-member-0000.cb-cluster-member.default.svc

In my appsettings.json, I have the following config:

"Couchbase": {
   "Servers": [
     "http://localhost:8091/pools" // I also tried without "/pools"
    ],
   "Username": "username",
   "Password": "password",
   "UseSsl": false

},

The full stacktrace is as follows:

After that, I repeatedly see:

dbug: Couchbase.Configuration.Server.Monitoring.ConfigMonitor[0]
      Waiting to check configs...

Which tells me it’s connected to the cluster. The following line immediately pops out to me:
Bootstrapping failed from http://localhost:8091/pools: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Couchbase.Utils.UnsupportedAddressFamilyException: http://cb-cluster-member-0000.cb-cluster-member.default.svc

It looks like it’s having trouble resolving the DNS name of the cluster I’m connected to (cluster member 0000). The other members names are 0001 and 0002. Is this because I’m port forwarding with that member, and thus addressing it as localhost:8091? If so, how do I connect to the cluster as a whole and not this specific member.

Once again, this cluster is hosted in Kubernetes inside Google COntainer Engine (GKE) using the Couchbase Autonomous Operator from the Marketplace.

EDIT:

I’ve been digging through the github repo, I think I found where the error gets thrown, but I still don;t quite know what I’m looking at here:

I attempted to resolve this by forwarding port 53 as well, but it failed to forward with a bind: permission denied

@foxtrotuniform6969 -

Hi, I don’t have much Kubernetes/GKE/Autonomous operator experiance, but I can possibily help isolate the issue for you.

There are two means of authenticating with the cluster which happens behind the scenes in the SDK - using TCP and memcached extended protocol or using HTTP streaming and a REST endpoint. Your stacktrace indicates that your failing both: a) TCP: “Connection refused…Cannot bootstrap with CCCP” using 127.0.0.1:11210 and b) HTTP: “Could not resolve hostname to IP…Couchbase.Utils.UnsupportedAddressFamilyException: http://cb-cluster-member-0000.cb-cluster-member.default.svc.

So, to be clear your not connecting to the server from the SDK - the client itself is not even fetching a cluster map, so it doesn’t know what the server topology looks like. One thing that sticks out to me, is the URI that is failing - it looks nothing like what I would expect to see from the Couchbase SDK: http://cb-cluster-member-0000.cb-cluster-member.default.svc - which could be automous operator produced?

Anyways, it looks like the client cannot do the DNS lookup with that URI on the client for HTTP streaming and the client cannot via 127.0.0.1:11210. Hopefully that helps and somebody with more experiance with Kubernetes/GKE/Autonomous operator can comment as well!

Jeff,

Thanks for the quick response, and happy Thanksgiving.

You’re absolutely right. Once I pushed the containerized application that was using Couchbase to the same cluster that CB was installed on, and used the DNS names for each node (i.e. http://cb-cluster-member-0000.cb-cluster-member.default.svc), the application functioned as expected.

I was hoping to use kubctl port forwarding to interact with the cluster in the cloud while running the consuming application on my local development box, but it seems that I went about it the wrong way.

Thanks you.
