Similar to `--no-negcache` on dnsmasq, this prevents issues which poll DNS for orchestration such as operators with StatefulSets. It can also be very confusing for users when negative caching results in a change they just made seeming to be broken until the cache expires. This assumes that 5 seconds is reasonable and will still catch repeated AAAA negative responses. We could also set the denial cache size to zero which should effectively fully disable it like dnsmasq in kube-dns but testing shows this approach seems to work well in our (albeit small) test clusters.
Cluster Configuration
Deprecation Notice: This directory has entered maintenance mode and will not be accepting new providers. Deployments in this directory will continue to be maintained and supported at their current level of support.
The scripts and data in this directory automate creation and configuration of a Kubernetes cluster, including networking, DNS, nodes, and control plane components.
See the getting-started guides for examples of how to use the scripts.
cloudprovider/config-default.sh contains a set of tweakable definitions/parameters for the cluster.
