Alibaba Cloud Managed Kubernetes Terraform - kubernetes

Question

I want to create Kubernetes cluster with Terraform,
Regarding the doc page here: https://www.terraform.io/docs/providers/alicloud/r/cs_managed_kubernetes.html
variable "name" {
default = "my-first-k8s"
}
data "alicloud_zones" main {
available_resource_creation = "VSwitch"
}
data "alicloud_instance_types" "default" {
availability_zone = "${data.alicloud_zones.main.zones.0.id}"
cpu_core_count = 1
memory_size = 2
}
Where do I insert vswitch id? and how to set the region id?

Answer 1

You can insert the vswitch id in the resource definition:
resource "alicloud_cs_managed_kubernetes" "k8s" {
name = "${var.name}"
availability_zone = "${data.alicloud_zones.main.zones.0.id}"
new_nat_gateway = true
worker_instance_types = ["${data.alicloud_instance_types.default.instance_types.0.id}"]
worker_numbers = [2]
password = "Test12345"
pod_cidr = "172.20.0.0/16"
service_cidr = "172.21.0.0/20"
install_cloud_monitor = true
worker_disk_category = "cloud_efficiency"
vswitch_ids = ["your-alibaba-vswitch-id"]
}
For the zones (if you want to override the defaults) based on this and the docs, you need to do something like this:
data "alicloud_zones" main {
available_resource_creation = "VSwitch"
zones = [
{
id = "..."
local_name = "..."
...
},
{
id = "..."
local_name = "..."
...
},
...
]
}

To set region:
While configuring Alicloud provider in Terraform itself you can set the region:
provider "alicloud" {
access_key = "${var.access_key}"
secret_key = "${var.secret_key}"
region = "${var.region}"
}
For instance, let me consider Beijing as the region:
provider "alicloud" {
access_key = "accesskey"
secret_key = "secretkey"
region = "cn-beijing"
}
To set vswitch IDs:
while defining the resource section we can insert the desired vswitches
resource "alicloud_instance"{
# ...
instance_name = "in-the-vpc"
vswitch_id = "${data.alicloud_vswitches.vswitches_ds.vswitches.0.id}"
# ...
}
For instance, let me consider vsw-25naue4gz as the vswitch id:
resource "alicloud_instance"{
# ...
vswitch_id = "vsw-25naue4gz"
# ...
}
