A terraform example to launching a kubernetes cluster in alibaba cloud.
These types of the module resource are supported:
This example can specify the following arguments to create user-defined kuberntes cluster
- alicloud_access_key: The Alicloud Access Key ID
- alicloud_secret_key: The Alicloud Access Secret Key
- region: The ID of region in which launching resources
- k8s_name_prefix: The name prefix of kubernetes cluster
- k8s_number: The number of kubernetes cluster
- k8s_worker_number: The number of worker nodes in each kubernetes cluster
- k8s_pod_cidr: The kubernetes pod cidr block. It cannot be equals to vpc's or vswitch's and cannot be in them. If vpc's cidr block is
172.16.XX.XX/XX, it had better to192.168.XX.XX/XXor10.XX.XX.XX/XX - k8s_service_cidr: The kubernetes service cidr block. Its setting rule is same as
k8s_pod_cidr - Other kubernetes cluster arguments
Note: In order to avoid some needless error, you had better to set new_nat_gateway to true.
Otherwise, you must you must ensure you specified vswitches can access internet before running the example.

terraform plan
Apply phase

This example can support the following creating kubernetes cluster scenario by setting different arguments.
You can specify the following user-defined arguments:
- vpc_name: A new vpc name
- vpc_cidr: A new vpc cidr block
- vswitch_name_prefix: The name prefix of several vswitches
- vswitch_cidrs: List of cidr blocks for several new vswitches
variable "profile" {
default = "default"
}
variable "region" {
default = "cn-hangzhou"
}
data "alicloud_vpcs" "default" {
is_default = true
}

new_nat_gateway = true
vpc_name = "tf-k8s-vpc"

k8s_service_cidr = "192.168.2.0/24"
k8s_worker_number = 2
}You can specify the following user-defined arguments:
- vpc_id: A existing vpc ID
- vswitch_ids: List of IDs for several existing vswitches
variable "profile" {

}
variable "region" {
default = "cn-hangzhou"
}
data "alicloud_vpcs" "default" {

}
module "k8s" {

vpc_id = data.alicloud_vpcs.default.vpcs.0.id

}You can specify the following user-defined arguments:
- vpc_id: A existing vpc ID
- vswitch_ids: List of IDs for several existing vswitches
- new_nat_gateway: Set it to false. But you must ensure you specified vswitches can access internet. In other words, you must set snat entry for each vswitch before running the example.
variable "profile" {
default = "default"
}
variable "region" {
default = "cn-hangzhou"
}
data "alicloud_vpcs" "default" {
is_default = true
}
module "k8s" {

new_nat_gateway = false

}From the version v1.4.0, the module has removed the following provider setting:
provider "alicloud" {
profile = var.profile != "" ? var.profile : null
shared_credentials_file = var.shared_credentials_file != "" ? var.shared_credentials_file : null
region = var.region
skip_region_validation = var.skip_region_validation
configuration_source = "terraform-alicloud-modules/kubernetes"
}If you still want to use the provider setting to apply this module, you can specify a supported version, like 1.3.0:
module "k8s" {
source = "terraform-alicloud-modules/kubernetes/alicloud"
version = "1.3.0"
region = "cn-hangzhou"
profile = "Your-Profile-Name"
new_nat_gateway = true
vpc_name = "tf-k8s-vpc"
// ...
}If you want to upgrade the module to 1.4.0 or higher in-place, you can define a provider which same region with previous region:
provider "alicloud" {
region = "cn-hangzhou"
profile = "Your-Profile-Name"
}
module "k8s" {
source = "terraform-alicloud-modules/kubernetes/alicloud"
new_nat_gateway = true
vpc_name = "tf-k8s-vpc"
// ...
}or specify an alias provider with a defined region to the module using providers:
provider "alicloud" {
region = "cn-hangzhou"
profile = "Your-Profile-Name"
alias = "hz"
}
module "k8s" {
source = "terraform-alicloud-modules/kubernetes/alicloud"
providers = {
alicloud = alicloud.hz
}
new_nat_gateway = true
vpc_name = "tf-k8s-vpc"
// ...
}and then run terraform init and terraform apply to make the defined provider effect to the existing module state.
More details see How to use provider in the module
| Name | Version |
|---|---|
| terraform | >= 0.12.0 |
| alicloud | >= 1.75.0 |
If you have any problems when using this module, please opening a provider issue and let us know.
