Rundeck tries to connect to node using ssh

[gaspo53]

After configuring Kubernetes nodes, while trying to run a command in one of the nodes, I'm getting:
Failed: ConfigurationFailure: SSH Keyfile does not exist: /home/rundeck/.ssh/id_rsa
Execution failed: 30 in project devops: [Workflow result: , step failures: {1=Dispatch failed on 1 nodes: [rundeck-node-65d4c8769c-762bm-rundeck-node: ConfigurationFailure: SSH Keyfile does not exist: /home/rundeck/.ssh/id_rsa + {dataContext=MultiDataContextImpl(map={}, base=null)} ]}, Node failures: {rundeck-node-65d4c8769c-762bm-rundeck-node=[ConfigurationFailure: SSH Keyfile does not exist: /home/rundeck/.ssh/id_rsa + {dataContext=MultiDataContextImpl(map={}, base=null)} ]}, status: failed]

Why is it trying to use SSH?
