Teardown Kubernetes

Edit online

Warning: Whenever you teardown the cluster be sure to back up your data first.

In order to change the default IP ranges, you must teardown your Kubernetes cluster.
```
$ sevone-cli cluster down
```
Ensure that the old IP address ranges are not left behind in any of your node’s routing tables.
```
$ ansible all --become -a "ip route del 192.168.96.0/24"
```

Adjust IP Ranges

Edit online

Create a file ip_ranges.yaml in /etc/ansible/group_vars/all directory with your new IP ranges.

Example

$ echo 'k3s_cluster_cidr: "10.42.0.0/16"' >> \
/etc/ansible/group_vars/all/ip_ranges.yaml

$ echo 'k3s_service_cidr: "10.43.0.0/16"' >> \
/etc/ansible/group_vars/all/ip_ranges.yaml

$ echo 'k3s_cluster_dns: "10.43.0.10"' >> \
/etc/ansible/group_vars/all/ip_ranges.yaml

You may then redeploy or proceed with your deployment as normal.

$ sevone-cli playbook up
