IMPORTANT!: This is just FYI and is strongly not recommended.

The below error may be seen in the logs which is just a warning and don’t cause any harm.

2022-12-19_11:18:21.76897 Warnings: [Elasticsearch built-in security features are not enabled. Without authentication, your cluster could be accessible to anyone. See Set up minimal security for Elasticsearch | Elasticsearch Guide [7.17] | Elastic to enable security.]

The below morpheus.rb option that can be switched from false to true.

elasticsearch['secure_mode'] = false

However, we don’t recommend configuring this setting in All-in-One and HA environments as we haven’t documented the manual steps for configuring TLS on nodes two and three. But that’s just a warning and you can totally ignore that.

Is elasticsearch[‘secure_mode’] recommended/supported on a single-node installation?

Reason I ask, when I enabled this setting on a Morpheus v 5.4.15 installation, morpheus-ctl bombed with the following error:

  • execute the ruby block elasticsearch_wait

  • execute[update elastic user password] action run

    ================================================================================
    Error executing action run on resource ‘execute[update elastic user password]’

Seems like it’s not recommended for All-in-One as well. The content has been updated.
