Unable to connect to DSS from container

[Krishna615]

Hi All,

I am trying to setup AKS in dataiku. I have successfully attached the AKS cluster with the dataiku from clusters tab in administration.

I am facing issue while testing it at the container execution tab in Setting. Below is the error I am getting while I try to test it.

Unable to connect to DSS from container : HTTPConnectionPool(host='xx.xx.xx.xx', port=10001): Max retries exceeded with url: /dip/api/tintercom/containers/get-execution (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f2ffae2fcf8>: Failed to establish a new connection: [Errno 110] Connection timed out',))

I have created the cluster from Azure portal UI. I have deployed the cluster in the same Vnet that my DSS instance is running. I have deployed DSS on Azure VM. I have also set the DSS IP in the env-set.sh file in bin folder.

I have been trying to fix it but could not. Can somebody please help me with the issue.

Thank you!

Hi,

the nodes of your AKS cluster need to be able to connect to the machine hosting DSS, which is not the case here. This points to a network setup issue, with either routes missing from the vnet or subnet where the AKS is deployed, or firewall rules on the DSS machine preventing inbound traffic from these nodes

So the test dataiku containers on the k8s cluster are trying to connect to the dataiku server on port 10001. Is this the only port that will be used for the cluster <--> dss_server communication or is there a range of ports that I should open so that when there is more containers running on the cluster, all of them could communicate with dss?

Thanks in advance.

No 10001 port is not just enough for dataiku to establish connection with the containers. There are range of ports that has to opened to allow communication between containers and dss instance. I don't have the list of ports but you can find the ports in the error traceback that, is where I have observed few ports.
