Simple go program to perform many DNS queries. This can be useful when trying to push load onto DNS servers. I need this container to simulate a DNS load on a GKE cluster.
To deploy in k8s:
kubectl create deployment dns-hammer --image=gcr.io/tyrionlannister-237214/dns-hammerThanks to OpenDNS for domains: https://github.com/opendns/public-domain-lists
- Periodically print out the performance instead of every resolution
- Print out average time to resolve
- For the above var, set the rate at which you want to print out the success rate
- Environment variable for concurrency
- Choose domains from the list randomly
- Set various log levels via an environment var
- Set a timeout for dns resolution, make the timeout configurable via argument
- Config map support
- Ability to do within cluster queries or out of cluster queries
