[SOLVED] Apache Ignite: Getting the current nodeId

Issue

I have an Apache Ignite cluster running with 4 nodes on Kubernetes. I want to make sure that the node are alive for the liveness probe. Basically, if a node is no responding I need to remove it from the cluster. I am looking on getting the nodeId of the Apache Ignite using the curl command. On a Apache Ignite pod, I can run curl "http://localhost:8080/ignite?cmd=version"

Is there a curl command using the REST API to get the current nodeId? I looked at the documentation, but I could not find anything https://ignite.apache.org/docs/latest/restapi

Thank you

Solution

You can get nodeId by using the node command and providing the node's IP address:

http://host:port/ignite?cmd=node&ip={nodeIp}

More information related to this endpoint can be found here.

Regarding the detection and removal of unresponsive nodes from the cluster, Apache Ignite does that automatically using the discovery mechanism. You can find additional details about that in the Detecting and Removing Failed Nodes from Topology section here.
