kubectl logs -f pod shows all logs from the beginning and it becomes a problem when the log is huge and we have to wait for a few minutes to get the last log. Its become more worst when connecting remotely. Is there a way that we can tail the logs for the last 100 lines of logs and follow them?

To get Kubectl pod logs, you can access them by adding the -p flag. Kubectl will then get all of the logs stored for the pod. This includes lines that were emitted by containers that were terminated.
kubectl logs –previous Well, kubectl logs will only show you the logs from a running container. But you can add –previous to the kubectl logs command to see the logs from a previously running container. It's a useful command for debugging purposes.
In a cluster best practices are to gather all logs in a single point through an aggregator and analyze them with a dedicated tool. For that reason in K8S, log command is quite basic.
Anyway kubectl logs -h shows some options useful for you:
# Display only the most recent 20 lines of output in pod nginx kubectl logs --tail=20 nginx # Show all logs from pod nginx written in the last hour kubectl logs --since=1h nginx Some tools with your requirements (and more) are available on github, some of which are:
