Dremio community edition in aks

1

I tried to deploy dremio in aks.I have used a VM B4ms ,size 4vcpu 16GB. Initially clone cloud tool and install dremio using helm install dremio_v2 .I had changed value.yml file with coordinator memory 4096 count 0 and volume 5gb…executor count 1 volume 5gb and mem 4096 and zk count 1 count 1…when installed using helm I saw pods dremio-master-0 ,dremio executor-0 ,zk.total 3 pods and dremio client also running. When I describe dremio client svc I can see loadbalancer with external ip and port 9047.but I am not able to see anything while opening that external ip in browser…

Is the pod count 3 what I got is correct?or do we need another coordinator for webapp…do you find any possible reason why I am not able to view web page.
I didn’t find any issues with vent inbound rules also…

I saw below when i get master logs
10.0..196 - - “GET / HTTP/1.1” 200 2592 “-” “kube-probe/1.21”

I have created AKS with advance networking(CNI) as we were not supposed to create our own vnet.

@ann These are not messages that causes master coordinator to not come up. Can you please provide the entire kubectl logs since startup?

5

For me master coordinator, executor and zk is up and running… Load balancer show external IP too .We have some company policy by which i cannot post entire logs… Let me check what can I give.

@ann Are you able to connect from a JDBC/OBDC tool and see if that works?

I tried connecting using Dbeaver with External Ip provided by loadbalancer… But I need password and username. With some default value it giving connection time out.

also conatiner logs show:
Readiness probe failed: Get "http://10.0..203:9047/": dial tcp 10.0..203:9047: connect: connection refused

@ann From the Master pod, are you able to get a response back for telnet localhost 9047 or does netstat -an | grep 9047 return that connection is established
