Docker upgrade from 4.7.4 to 4.8.1 issue

[Daniel D'Angeli]

Hi,

i am trying to upgrade the docker deployment of multi node Wazuh from 4.7.4 to 4.8.1 and this is what i have done so far:

- Replaced "vulnerability-detector" with the new " vulnerability-detection ":
<vulnerability-detection>
  <enabled>yes</enabled>
  <index-status>yes</index-status>
  <feed-update-interval>60m</feed-update-interval>
</vulnerability-detection>

- Added the new indexer blocked and configured as per the documentation:

  <indexer>
    <enabled>yes</enabled>
    <hosts>
      <host>https://wazuh1.indexer:9200</host>
      <host>https://wazuh2.indexer:9200</host>
      <host>https://wazuh3.indexer:9200</host>
    </hosts>
    <ssl>
      <certificate_authorities>
        <ca>/etc/ssl/root-ca.pem</ca>
      </certificate_authorities>
      <certificate>/etc/ssl/filebeat.pem</certificate>
      <key>/etc/ssl/filebeat.key</key>
    </ssl>
  </indexer>

Every service seems to work fine apart from the Wazuh master container, which keeps restarting and outputs the following error:

Hi Daniel,

Thanks for using wazuh!

This is a Filebeat error, as discussed here: https://github.com/wazuh/wazuh-packages/issues/1665#issuecomment-1165698879

An alternative solution is proposed, add the following lines in filebeat.yml:
seccomp: default_action: allow syscalls: - action: allow names: - rseq

Could you apply this, and confirm how it works?

Hi,

it seems to have worked but now there is an issue with the Wazuh Dashboard:

It seems like its trying to create a different index on Wazuh indexer for its settings but failing? And why should it do it?

Hi Daniel,

Sorry for the late response.

You can check the indexes with this command:

curl -X GET "https://localhost:9200/_cat/indices/.kibana*?v&s=index" -u user:pass -k

If you see that the index kibana_5 already exists, check the alias with this command and verify where it is pointing to:

curl -X GET "https://localhost:9200/_cat/aliases?pretty" -u user:pass -k

Check if kibana_5 has documents.

We want to check that the alias of kibana_5 is pointing to another kibana or not, then we need to check if kibana_5 has documents, in case it doesn't we can delete it, then restart wazuh-dashboard, and this will solve the problem, because wazuh-dashboard will recreate the Kibana_5, copy the objects from other kibana  and finally change the Alias to Kibana_5.

If you want to delete the index, run the following command:

curl -X DELETE -k -u <user>:<password> https://<wazuh-indexer-ip>:9200/.kibana_5

Then restart the wazuh dashboard:

systemctl restart wazuh-dashboard

Wait for few minutes and try to access the dashboard.

Let me know if this helps you.

Hi,

it seems to have worked but now there is another issue. When i login it says Application not found in the /app/wazuh URI.

Any tips?

Regards,

Daniel D.

[Delfina Lizarralde Bressan]

The message Application Not Found when accessing the wazuh dashboard after upgrading might be that the configuration file /etc/wazuh-dashboard/opensearch_dashboards.yml wasn't overwritten with new changes.

To resolve this issue, update the uiSettings.overrides.default route setting with the /app/wz-home value in the configuration file /etc/wazuh-dashboard/opensearch_dashboards.yml :
uiSettings.overrides.defaultRoute: /app/wz-home

Restart the wazuh-dashboard using the command:
systemctl restart wazuh-dashboard

Refer to https://documentation.wazuh.com/current/upgrade-guide/troubleshooting.html

[Delfina Lizarralde Bressan]

If this does not work, please share the output of these commands:
# tail /etc/wazuh-dashboard/opensearch_dashboards.yml

# cat /var/ossec/logs/ossec.log | grep -i -E "error|warn"

[Daniel D'Angeli]

Now everything seems up and running, thank you very much!
