Code & tools
kail streams logs from all containers of all matched pods.
You can match pods by service, replicaset, deployment, and others.
Adjusts to a changing cluster - pods are added and removed from logging as they fall in or out of the selection.
kube-lock sits as an intermediary between you and kubectl, allowing you to lock and unlock contexts.
It prevents misfires to production / high-value Kubernetes clusters that you might have strong IAM privileges on.
