I have created a local Kubernetes cluster with kind. Following are changes you need to get metric-server running on Kind.

Deploy latest metric-server release.

kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.5.0/components.yaml

Within existing arguments to metric-server container, you need to add argument --kubelet-insecure-tls.

Follow the steps to increase or decrease the size of VM in Google Cloud :

1. Goto https://console.cloud.google.com
2. Goto Compute Engine tab, followed by VM Instances.
3. Select the VM for which you want to increase/decrease the disk size.
4. Under Boot disk, you will see one(or more) disks for the VM. Click on one for which you desire to update disk size.
5. Click Edit in the top. Then, modify the Size. At last, click on save.
6. Now, we just need to tell the OS to grow the partition to the total size. This can be done by executing following commands :

fdisk -l
growpart /dev/sda 1

GENERAL TIPS

Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups command.

1. List the topics to which the group is subscribed

kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe

Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

2. Reset the consumer offset for a topic (preview)
