@ -76,7 +76,7 @@ A few things to note here:
|
|||
- The "--master-zones=us-east-1a,us-east-1b,us-east-1c" KOPS argument will actually enforce we want 3 masters here. "--node-count=2" only applies to the worker nodes (not the masters). Again, real "HA" on Kubernetes control plane requires 3 masters.
|
||||
- The "--topology private" argument will ensure that all our instances will have private IP's and no public IP's from amazon.
|
||||
- We are including the arguments "--node-size" and "master-size" to specify the "instance types" for both our masters and worker nodes.
|
||||
- Because we are just doing a simple LAB, we are using "t2.micro" machines. Please DONT USE t2.micro on real production systems. Start with "t2.medium" as a minimum realistic/workable machine type.

- And finally, the "--networking kopeio-vxlan" argument. With the private networking model, we need to tell kops which networking subsystem to use. More information about kops supported networking models can be obtained from the [KOPS Kubernetes Networking Documentation](https://github.com/kubernetes/kops/blob/master/docs/networking.md). For this exercise we'll use "kopeio-vxlan" (or "kopeio" for short).

|

**NOTE**: You can add the "--bastion" argument here if you are not using "gossip dns" and create the bastion from start, but if you are using "gossip-dns" this will make this cluster to fail (this is a bug we are correcting now). For the moment don't use "--bastion" when using gossip DNS. We'll show you how to get around this by first creating the private cluster, then creation the bastion instance group once the cluster is running.

```bash
