Hello,

I have issues adding a PostgreSQL database to the ClusterControl. I am new to ClusterControl.
We have a backend that uses a PostgreSQL database and I was about to do a load test. Therefore, I wanted to monitor the system and the database and ClusterControl seems to do that just great.

I run ClusterControl and the PostgreSQL database using docker. I followed this tutorial (https://severalnines.com/database-blog/how-deploy-postgresql-docker-container-using-clustercontrol) to set it up, but when trying to add "Import cluster" it fails.

The job detail error log:

[11:21:56]:Adding existing cluster has failed.
[11:21:56]:<em style='color: #2ecc71;'>matrix-postgres</em>:5432: OS detection failure Failed to extract version information of the OS at host matrix-postgres. The received host information:

Hope someone can help. Thanks a lot!

  Hi Hanno.

  Alpine Linux v3.10 is not supported by ClusterControl, which explains why you saw those errors. You could use other supported operating systems like CentOS 6/7, RHEL 6/7, Debian and Ubuntu for the PostgreSQL host, and re-import it back into ClusterControl.

  Regards,
  Ashraf
