When our infrastructure team performs deployments for patch management the command firewall-cmd --reload is executed. The result is that all rules dynatrace in firewalld are destroyed.
Could you make the rules persistent to prevent this problem ?
Please align with your infrastructure team to ensure ./reconfigure.sh is run after system patching. This should apply required firewall rules at the cluster node.
It isn't possible for us we had considered this solution but given the number of customers our system team did not see to manage specificities for each of them. And
Yes it is, but our system team can't tell us when the reload is done so between the reload and time when the problem is detected the cluster is unavailable even if the problem is detected rapidly in production environement this isn't acceptable.
