add worker-node to docker deployment

[doc dodo]

Hello,

Can I add worker node to docker deployment?

If I start another worker node then it start work, but all agent is connected to master and worker1. Worker2  is not in use.

Hi there!

As per your message, I understand that you want to add a new Wazuh Manager Worker node. I'm emphasizing this because the Indexer is also a cluster, and therefore can be extended or shrinked by adding/removing new nodes.

Did you add the new worker node to the nginx.conf file?

Yes, I added worker2:

    upstream mycluster {
        hash $remote_addr consistent;
        server wazuh.master:1514;
        server wazuh.worker:1514;
        server wazuh.worker2:1514;
    }

In ossec.conf (/opt/wazuh-docker/multi-node/config/wazuh_cluster/wazuh_worker2.conf)

  <cluster>
    <name>wazuh</name>
    <node_name>worker02</node_name>
    <node_type>worker</node_type>
    <key>397f2bc2849139592be7ae966d0c141d</key>
    <port>1516</port>
    <bind_addr>0.0.0.0</bind_addr>
    <nodes>
        <node>wazuh.master</node>
    </nodes>
    <hidden>no</hidden>
    <disabled>no</disabled>
  </cluster>

And added volumes in docker-compose:

  worker-wazuh-api-configuration2:
  worker-wazuh-etc2:
  worker-wazuh-framework2:
  worker-wazuh-queue2:
  worker-wazuh-var-multigroups2:
  worker-wazuh-integrations2:
  worker-wazuh-active-response2:
  worker-wazuh-agentless2:
  worker-wazuh-wodles2:
  worker-filebeat-etc2:
  worker-filebeat-var2:

New container started without errors, but agents connected onlt to manager and worker01.

Problem was resolved after manual adding configs to  worker-wazuh-etc2 and  worker-wazuh-integrations2.
