Re-configuring deployment DNS through the TKGI Management console

Products

• VMware Tanzu Kubernetes Grid Integrated Edition

Issue/Introduction

Updating the DNS configurations for the TKGI deployment from the TKGI management console will show the input validation errors:

Input validation failed Validation errors found: Fail to parse network : invalid CIDR address:

Resolution

This is a bug from TKGI MC, we have a workaround as follows:

Step 1:  Change the deployment DNS in the TKGI MC deployment yaml, but they have to input the deployment CIDR (It can be any CIDR that does not contain the deployment DNS IP), this CIDR will not affect the user's original CIDR configuration, for example:

network:
  active_t0_edge_node: ""
  active_t0_edge_node_ip: ""
  additional_dep_reserved_ip_ranges: ""
  additional_sev_reserved_ip_ranges: ""
  autoprovision_nsx: false
  dep_dns: xx.xx.xx.xx
  dep_network_cidr: "x.x.x.x/24"
  dep_network_gateway: ""

Step 2:  After editing, click “APPLY CONFIGRATION“
