Elasticsearch in HCL Connections Componentpack is secured with Searchguard and needs certificates to work properly. These certificates are generated by bootstrap during the initial container deployment with
These certificates are valid for 10 years (
chain_ca.pem) or 2 years (
elasticsearch*.pem) and stored in the Kubernetes secrets
elasticsearch-7-secret. So when your HCL Connections deployment is running for 2 years, the certficates stop working.
Last week I played around with the HCL Connections documentation to backup Elasticsearch in the article Backup Elasticsearch Indices in Component Pack .
In the end I found that I couldn’t get the snapshot restored and that I have to run a command outside of my Kubernetes cluster to get a snapshot on a daily basis. That’s not what I want.
During a migration from Cognos Metrics to Elasticsearch Metrics, I had some issues with the index. So I wanted to create a backup of the already migrated data and start over from scratch.
The official documentation has an article on the topic: Backing up and restoring data for Elasticsearch-based components , but I had to slightly adjust the commands to get a successful snapshot.
