Changing the IP Address of a Master or Worker Node

You can assign a master or worker node a new IP address by deleting the node, and then re-adding the node with the new FQDN.

To change the IP address of a master or worker node:

  1. Note the FQDN, current IP address, and new IP address of the node for which you wish to assign a new IP address.
  1. Log in to the CDF Management Portal (https://<ha-address>:5443).
  2. Click Cluster > Nodes.
  3. Click + Add.
  4. Next to the node for which you plan to change the IP address, in the Operations column, click Delete.
  5. Enter the username and password/keyphrase to confirm node deletion. Remain on the page and verify that the node has been deleted. Give the process time to complete.
  6. Outside of CDF, perform the necessary changes within your network administration or host settings to change the old IP address of the node to the new IP address.
  7. In the CDF Management Portal, on Cluster > Nodes.
  8. Click + Add.
  9. Enter the FQDN of the node which you are re-adding.
  10. Enter values for the pop-up dialog as prompted. For host name, use the new (existing) FQDN of the node you deleted in Step 5.
  11. Click ADD, and then wait for the confirmation that new node has been added to the cluster.
  12. Ensure that you add the appropriate labels to the node that you re-added.
