A terraform module to provide an Alicloud VPC, VSwitch and configure route entry for it.

• The module contains one VPC, several VSwitches and several custom route entries.
• If VPC is not specified, the module will launch a new one using its own parameters.
• The number of VSwitch depends on the length of the parameter vswitch_cidrs.
• The number of custom route entry depends on the length of the parameter destination_cidrs
• If you have no idea availability zones, the module will provide default values according to cpu_core_count and memory_size.

The module aim to build a VPC environment. Its input variables contains VPC, VSwitch and Route Entry.

• alicloud_access_key - The Alicloud Access Key ID to launch resources
• alicloud_secret_key - The Alicloud Access Secret Key to launch resources
• region - The region to launch resources - default to "cn-hongkong"
• availability_zones - List of availability zone IDs to launch several VSwitches in the different zones and its item is "" means the value will be from zones' data source - default to [""]
• number_format - The number format used to mark multiple resources - default to "%02d"

• vpc_id - VPC ID to launch a new VSwitch and Security Group
• vpc_cidr - VPC CIDR block to launch a new VPC when vpc_id is not specified - default to "172.16.0.0/12"
• vpc_name - VPC name to mark a new VPC when vpc_id is not specified - default to "TF-VPC"
• vpc_description - VPC description used to launch a new vpc when 'vpc_id' is not specified - default to "A new VPC created by Terrafrom module tf-alicloud-vpc-cluster"

• vswitch_name - VSwitch name prefix to mark a new VSwitch - default to "TF_VSwitch"
• vswitch_cidrs - List of VSwitch CIDR blocks to launch several new VSwitches
• vswitch_description - VSwitch description used to describe new vswitch - default to "New VSwitch created by Terrafrom module tf-alicloud-vpc-cluster."

• route_table_id - Route table ID of virtual router in the specified VPC. If vpc_id is not specified, you must specify route_table_id when to launch new route entries.
• destination_cidrs - List of destination CIDR blocks of virtual route table in the specified VPC
• server_ids -List of ECS instance IDs as route entry's next hop in the specified VPC

You can use this in your terraform template with the following steps.

1. Adding a module resource to your template, e.g. main.tf

    module "tf-vpc-cluster" {
       source = "github.com/alibaba/terraform-alicloud-vpc"
   
       alicloud_access_key = "${var.alicloud_access_key}"
       alicloud_secret_key = "${var.alicloud_secret_key}"
   
       vpc_name = "my_module_vpc"
   
       vswitch_name = "my_module_vswitch"
       vswitch_cidr = [
          "172.16.1.0/24",
          "172.16.2.0/24"
       ]
   
       destination_cidrs = "${var.destination_cidrs}"
       nexthop_ids = "${var.server_ids}"
   
    }
   

2. Setting values for the following variables, either through terraform.tfvars or environment variables or -var arguments on the CLI

• alicloud_access_key
• alicloud_secret_key
• destination_cidrs
• server_ids

• vpc_id - A new VPC ID
• vswitch_ids - A list of new VSwitch IDs
• router_id - The virtual router ID in which new route entries are launched
• route_table_id - The route table ID in which new route entries are launched
