client node connects to server nodes behind NAT
Hi,
Is that possible for a non-Kubernetes client node connects to server nodes within Kubernetes ?
have read below docs seems impossible
https://ignite.apache.org/docs/latest/installation/kubernetes/azure-deployment#connecting-client-nodes
Have tried with thin client outside of Kubernetes - that works fine
client node(thick client) - always throw exceptions, most likely the internal ips bebind NAT cannot be detected from external , is there any workaround to implement that non-Kubernetes client node connects to server nodes within Kubernetes ? I'd like to utilise the power features of thick client. and They can be depoloyed everywhere if there is the way of making it.
Thanks,
Ma Jun

Hi Ma,
Streaming is supported for the thin clients (see a related discussion on
the user list). As for the peer-class-loading support, not sure that it's
coming. As an alternative, you can implement the UriDeploymentSpi interface
that will load/reload code from your custom location/repository:
https://ignite.apache.org/docs/latest/code-deployment/deploying-user-code
If you don't want to bother with the UriDeploymentSpi implementation, then
check this Deployment feature of GridGain Nebula (it will be available for
non-Nebula clusters through the same Control Center interface soon). That
feature implements the UriDeploymentSpi:

Finally, as Max suggested, configure the thick client and server nodes
following this documentation:
https://ignite.apache.org/docs/latest/clustering/running-client-nodes-behind-nat
(it should solve your networking problems).

Hi!
Unfortunately, support of peer class loading and data streams is limited
for thin clients. AFAIK, .Net thin client supports data streamer.
I found that Ignite has a special mode of running client nodes
`forceClientToServerConnections` [1]. But this feature is marked as
experimental since 2.9 and I don't see any updates there. Actually, I'm not
aware about this feature much. I found the feature discussion on dev list
[2]. Maybe somebody from the community can say more about this feature. But
looks like it can be a solution in your case.

That would be peer class loading && data stream .

Hi, I'll touch on a similar topic a little tomorrow on IgniteSummit [1], you're welcome :)
But, a thick client is part of topology, and it has to be able to connect every node in the cluster directly, then thick clients have to be run within the same kubernetes cluster. Thin clients were designed to eliminate this problem.
What features of thick clients do you want to use?
