Cannot access redis in cluster from visual studio

[step42]

My services has a redis connection string configured like redis-headless.infra.svc.cluster.local:6379,password=xyz. I added

• name: REDIS value: $(services:redis-headless.infra) to the KubernetesLocalProcessConfig.yaml

The code throws socket exceptions Exception thrown: 'System.Net.Sockets.SocketException' in Pipelines.Sockets.Unofficial.dll Exception thrown: 'StackExchange.Redis.RedisConnectionException' in StackExchange.Redis.dll Exception thrown: 'System.Net.Sockets.SocketException' in System.Net.Sockets.dll Exception thrown: 'StackExchange.Redis.RedisConnectionException' in System.Private.CoreLib.dll

kubectl get services -n infra NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE ... redis-headless ClusterIP None 6379/TCP 5d1h redis-master ClusterIP 10.43.186.44 6379/TCP 5d1h redis-metrics ClusterIP 10.43.118.255 9121/TCP 5d1h

I am using Visual Studio 2022

@step42 Can you share the logs from the following location please ? C:\Users\youruserid\AppData\Local\Temp\Bridge To Kubernetes, please send all the logs from this location after getting this error. ex: bridge-*.txt files. Thank you.

[step42]

bridge-logs.zip Sorry for the late respone. Attached the logs. Please let me know if you need anything else

I can connect to redis if I change the connection string from redis-headless.infra:6379 to redis-master.infra:6379

@hsubramanianaks can you please update the state. I provided my response and would like to know how to proceed. Thanks

@step42 can you check your k8s cluster for pod you are deubgging , it would be running image lpkremoteagent-* and see if you grab the logs for it? I feel the remote agent pod running in your k8s cluster which communicates k8s cluster --> local ane vice versa is not coming up. I can see error in the logs

[step42]

I can see that the pod I am debugging got replaced with bridgetokubernetes.azurecr.io/lpkremoteagent:1.3.4 Here are the logs of the pod sysconfig.log I also attached the bridge logs files again from the same session

@step42 seems like connection between your local machine and k8s cluster is not happening, port forwarding is failing due to network issues. do you have any VPN/firewall that is blocking connections or is this some kind of private cluster only people with right access can port forward?

can you try normal port forward without bridge from your local machine to see if it works please ?

[step42]

Port Forwarding works. It also works if I connect to redis-master instead of redis-headless service through the bridge. The only difference I can see there is that redis-master has an IP and redis-headless has no IP

redis-headless                            ClusterIP      None            <none>           6379/TCP                     6d22h
redis-master                              ClusterIP      10.43.60.181    <none>           6379/TCP                     6d22h

Do you want any log files when connecting to redis-master through b2k?
