- We will now create our cluster. There will be either one or two small changes. The first is that we will specify `-i inventory/kubespray-aws-inventory.py` as our inventory script. The other is conditional. If your AWS instances are public facing, you can set the `VPC_VISIBILITY` variable to `public` and that will result in public IP and DNS names being passed into the inventory. This causes your cluster.yml command to look like `VPC_VISIBILITY="public" ansible-playbook ... cluster.yml`

**Optional** Using labels and taints
|
||||
|
||||
To add labels to your kubernetes node, add the following tag to your instance:
|
||||
|
||||
- Key: `kubespray-node-labels`
|
||||
- Value: `node-role.kubernetes.io/ingress=`
|
||||
|
||||
To add taints to your kubernetes node, add the following tag to your instance:
|
||||
|
||||
- Key: `kubespray-node-taints`
|
||||
- Value: `node-role.kubernetes.io/ingress=:NoSchedule`
|
||||
|
||||
## Kubespray configuration
|
||||
|
||||
Declare the cloud config variables for the `aws` provider as follows. Setting these variables are optional and depend on your use case.
