Aria Automation creates DNS Flood with "contour" requests.

Products

• VMware Aria Suite

Issue/Introduction

After upgrading Aria Automation to version 8.18.1 the DNS servers are receiving thousands of IPv6 requests.

Environment

VMware Aria Automation 8.18.1

Cause

The new ingress controller "contour" was introduced in Aria Automation 8.18.1 in place of the old "traefik".

Resolution

This procedure is applicable to both single-node and clustered environments. In a clustered environment, it should be performed from any one of the nodes.

Workaround:

1. SSH into the Aria Automation appliance.
2. Edit the /opt/charts/contour/values.yaml file. Add/modify the configInline section as follows:
        configInline:
       cluster:
          dns-lookup-family: v4
3. Restart Aria Automation services with the following command:

                        /opt/scripts/deploy.sh

Post-validation:

1. SSH into any node of the Aria Automation appliance.
2. Run the command cat /opt/charts/contour/values.yaml to check if the changes have been applied. If the values are present, the changes have been successfully made.
