```sh
firewall-cmd --get-active-zones
```

This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is `public`, use

```sh
firewall-cmd --zone=public --add-port=9000/tcp --permanent
```

enabled (CentOS), you can use `firewall-cmd` command to allow traffic to specific ports. Use below commands to allow access to port 9000 ```sh firewall-cmd --get-active-zones ``` This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is `public`, use ```sh firewall-cmd --zone=public --add-port=9000/tcp --permanent ``` Note that `permanent` makes sure the rules are persistent across firewall start, restart or reload. Finally reload the firewall...

* Change eviction logic in NodeController and make it Zone-aware ([#28897](https://github.com/kubernetes/kubernetes/pull/28897), [@gmarek](https://github.com/gmarek))
    * Change eviction policies in NodeController:
      *  add a "partialDisruption" mode, when more than 33% of Nodes in the zone are not Ready
      *  add "fullDisruption" mode, when all Nodes in the zone are not Ready

- The new `-gce-zones` flag on the `e2e.test` binary instructs tests that check for information about how the cluster interacts with the cloud to limit their queries to the provided zone list. If not specified, the current behavior of asking the cloud provider for all available zones in multi zone clusters is preserved.
