IPAM integration and ABX actions on Cloud Extensibility Proxy fail to access the network after k8s subnet CIDR addresses have been changed

Products

• VMware Aria Suite

Issue/Introduction

This article provides information on a workaround for the issue and correct the broken network access for ABX actions.

Symptoms:

• You have made changes to k8s subnet CIDR addresses
• In /data1/abx-agent-logs/abx-agent.log you see errors similar to:

java.net.UnknownHostException: data.mgmt.cloud.vmware.com

java.net.UnknownHostException: proxy-service.prelude.svc.cluster.local

Cause

ABX agent is started using a docker run command, which provides the hardcoded kube-dns address. When k8s subnets are changed, the kube-dns address is no longer valid and ABX actions have no access to the proxy and hence no network access.

Resolution

VMware is aware of this issue.

A resolution for this issue is being evaluated for inclusion in a future release.

Workaround:

To work around this issue you will need to follow these steps:

1. Log into the Cloud Extensibility Proxy appliance using SSH or console.
2. Execute the following command:
