Go

Write a script in Go that redeploys all pods in a Kubernetes cluster that have the word database in the name.

Requirements:

• Assume local credentials in your kube config have full access. There is no need to connect via a service account, etc.
• You must use the client-go library.
• Your script must perform a graceful restart, similar to kubectl rollout restart. Do not just delete pods.
• You must use Go modules (no vendor directory).
