Hello everybody We encountered a few issues with the security configuration required for Elasticsearch 7.17 since upgrading from ES6. We started with the minimal security setup documentation https://www.elastic.co/guide/en/elasticsearch/reference/7.17/security-minima... and we have a cluster with multiple nodes, so moved on to the basic security setup documentation https://www.elastic.co/guide/en/elasticsearch/reference/7.17/security-basic-... but found we were getting all kinds of errors that we didn't know how to handle. Has anyone else implemented security for a multi-node Elasticsearch 7 cluster that could provide some insights? -- *Aleisha Amohia (she/her)* Technical Lead | Rōpū kohinga *Catalyst.Net Limited - Expert Open Source Solutions* *Catalyst.Net Ltd - a Catalyst IT group company* Tel: +64 4 803 2259 or +61 3 9116 2642 | www.catalyst.net.nz <http://www.catalyst.net.nz> Follow Catalyst Koha on Twitter <https://twitter.com/catalystkoha> | Subscribe to the Catalyst Koha newsletter <https://catalyst.us4.list-manage.com/subscribe?u=62457ff5060d15ee3c07d3fc4&id=b73fbdcac8> Catalyst Logo CONFIDENTIALITY NOTICE: This email is intended for the named recipients only.
