I am trying to setup the basic setup of minifi found at https://nifi.apache.org/minifi/getting-started.html. I am running nifi and minifi in a docker container. I’ve buit the config.yml file and put it in the minifi_home/conf directory. Here the log from minifi:

2024-06-05 15:21:37,718 WARN [Timer-Driven Process Thread-1] o.apache.nifi.remote.client.PeerSelector Available peers collection is empty; no peer available
2024-06-05 15:21:42,332 WARN [NiFi Site-to-Site Connection Pool Maintenance] o.apache.nifi.remote.client.PeerSelector Could not communicate with 192.168.210.xx:10000 to determine which node(s) exist in the remote NiFi instance, due to java.net.ConnectException: Connection refused (Connection refused)
2024-06-05 15:21:42,333 WARN [NiFi Site-to-Site Connection Pool Maintenance] o.apache.nifi.remote.client.PeerSelector Unable to refresh remote group peers due to: Unable to retrieve nodes from remote instance

I don’t understand why the nifi remote client is trying to communicate with the port 10000 and what should be behind this port.

I’ve read seen a post about the same problem but nothing seems to work.

I’ve tried to modify the nifi.properties inside the conf directoy of minifi to add the properties :
nifi.remote.input.host=

nifi.remote.input.secure=

nifi.remote.input.socket.port=

nifi.remote.input.http.enabled=

nifi.remote.input.http.transaction.ttl=

but the file is overwrited at run time..

Here my confi.yml if it helps:
