[plugin-barman-cloud] Readiness probe does not allow HA

[faymard]

Hi,

We are using the plugin-barman-cloud chart to use object storage for backups. For HA requirements, we increased the replicaCount to 2 or 3, and we notice that inactive pods do not open port 9090. They open it when they achieve lease acquisition, but until then they are marked as down, which triggers false positive alerts and noise.

Is there anything we can do to mitigate this ?

Regards,
