Terraform

Terraform is a popular IaC tool. You can create VMs on public cloud with one command.

Aliyun & AWS templates are used as example providers. You can take terraform.tf as an example.

Get Started

You can install terraform with homebrew on macOS

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew install terraform

Then init terraform cloud provider, adjust the terraform.tf config file and apply it:

terraform init
terraform apply #-auto-approve

Print public IP Address:

terraform output | grep -Eo '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'

AWS Setup

You have to set up aws config & credential to use AWS provider.

# ~/.aws

# ~/.aws/config
[default]
region = cn-northwest-1

# ~/.aws/credentials
[default]
aws_access_key_id = <YOUR_AWS_ACCESS_KEY>
aws_secret_access_key =  <AWS_ACCESS_SECRET>

# ~/.aws/pigsty-key
# ~/.aws/pigsty-key.pub

There’s a contrib example for AWS (Amazon Web Services), but it’s not actively maintained.

• spec/aws-cn.tf : AWS 4 node CentOS7 environment

Aliyun Setup

You can add your aliyun credentials to the environment file, such as ~/.bash_profile

export ALICLOUD_ACCESS_KEY="<your_access_key>"
export ALICLOUD_SECRET_KEY="<your_secret_key>"
export ALICLOUD_REGION="cn-beijing"

Example config files:

• spec/aliyun-meta.tf : Aliyun 1 meta node template for all distro & amd/arm (default)
• spec/aliyun-full.tf : Aliyun 4-node sandbox template for all distro & amd/arm.
• spec/aliyun-oss.tf : Aliyun 5-node building template for all distro & amd/arm.

Here are example ECS public OS images used in Aliyun:

QCloud Setup

There’s a contrib example for QCloud (Tencent Cloud), but it’s not actively maintained.

• spec/tencentcloud.tf : QCloud 4 node CentOS7 environment
