Cluster version 1.320+
As you develop your infrastructure, we aim to adapt the Dynatrace Managed deployment to the dynamic nature of cloud-based data centers.
Dynatrace Managed relies on static IP addresses, but the IP reconfiguration feature allows you to dynamically reconfigure the IP address on a node without the need to remove the node and then install a new one.
For a successful IP address reconfiguration, your cluster must have at least three nodes.
If both the old and new IP addresses are assigned to the same machine, ensure that the routing table is configured to route all outgoing traffic to other cluster nodes exclusively through the new IP address.
The IP address reconfiguration can also serve as an alternative to:
Make sure all node data is available on the node you want to reconfigure. You can do it:
Run the script below on the node you want to reconfigure:
/opt/dynatrace-managed/installer/migrate-ip-local.sh --seed-auth <cluster-token>
The script takes some time, even up to one hour. When it finishes, the node should be visible in the cluster under the new IP address.
Additionally, the cluster administrator gets notified that IP reconfiguration is in progress by the cluster event.
You can find the main log in /var/log/dynatrace/install.log on the reconfigured machine. Many components on all nodes take part in this process, so details of each step can be found in the relevant logs.
Yes, you can run the script multiple times, but one at a time.
You need to specify the IP address you want to use for Dynatrace using the --cluster-ip <ip-for-dynatrace> parameter.
No, you can change only one node at a time.
Check the log and try to fix the issue. Then, you can run the script again.
