7.4. Elasticsearch Cluster Update

If you are running an Elasticsearch Cluster with your Analysis Cockpit, we recommend to update the cluster members anytime you are installing an update on your Analysis Cockpit. Not only might an update for the Analysis Cockpit contain an update for Elasticsearch, but more importantly, system and security updates for the underlying debian system are also included.

To update your cluster members, run the following commands on each of them:

nextron@node-1:~$ sudo apt update
nextron@node-1:~$ sudo apt upgrade


Performing system updates is usually risk free. However, we still recommend that you create a backup/snapshot before updating your cluster nodes.
