以Terraform为代表的资源编排类
tf 文件在 Vim 中的语法加亮是安装的hashivim/vim-terraform;插件
Terraform被设计成一个多云基础设施编排工具，不像CloudFormation那样绑定AWS平台，Terraform可以同时编排各种云平台或是其他基础设施的资源。Terraform实现多云编排的方法就是Provider插件机制。

wget -c https://releases.hashicorp.com/terraform/0.15.4/terraform_0.15.4_linux_amd64.zip
unzip terraform_0.15.4_linux_amd64.zip
#sudo mv terraform /usr/bin/
mkdir /home/evan/data/apps/terraform && mv terraform /home/evan/data/apps/terraform/
echo 'export PATH=/home/evan/data/apps/terraform:$PATH' >> /etc/profile
echo 'export PATH=/home/evan/data/apps/:$PATH' >> /etc/profile #这个不行 少了一个目录 找不到了
写在你的home ~/.profile 也是可以的 为你本用户使用方便
export PATH=/home/evan/data/apps/terraform:$PATH

像 git 一样，每个 Terraform 项目需要自己单独的目录空间，所以我们创建一个 terraform-learning 目录
mkdir terraform-learning
cd terraform-learning
该目录下的所有 *.tf 文件都会被 Terraform 加载，在初始化 Terraform 工作空间之前必须至少要有一个 *.tf 文件。我们这里建立文件 main.tf, 内容如下
terraform的安装和应用

evan@myxps:~/.terraform.d$ cat terraform.tf

vpc_name = "tf_test_foo"
cidr_block = "172.16.0.0/12"
}
resource "alicloud_vswitch" "vsw" {
vpc_id = alicloud_vpc.vpc.id
cidr_block = "172.16.0.0/21"
zone_id = "cn-guangzhou-b"
}
evan@myxps:~/.terraform.d$ terraform init #自动安装了alicloud provider plugis

Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.

Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
terraform apply #
evan@myxps:~/.terraform.d$ terraform apply
alicloud_vpc.vpc: Refreshing state... [id=vpc-7xvsw3jjadaf53zjlido6]
Terraform used the selected providers to generate the following execution plan.
Resource actions are indicated with the following symbols:
+ create
Terraform will perform the following actions:
# alicloud_vswitch.vsw will be created
+ resource "alicloud_vswitch" "vsw" {
+ availability_zone = (known after apply)
+ cidr_block = "172.16.0.0/21"
+ id = (known after apply)
+ name = (known after apply)
+ status = (known after apply)
+ vpc_id = "vpc-7xvsw3jjadaf53zjlido6"
+ vswitch_name = (known after apply)
+ zone_id = "cn-guangzhou-b"
}
Plan: 1 to add, 0 to change, 0 to destroy.
Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.
Enter a value: yes
alicloud_vswitch.vsw: Creating...
alicloud_vswitch.vsw: Creation complete after 6s [id=vsw-7xvwa2oq0fsjm3xuhv9ss]
Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

打开 web 有了
terraform show ##查看已创建的专有网络和交换机
# alicloud_vpc.vpc:
resource "alicloud_vpc" "vpc" {
cidr_block = "172.16.0.0/12"
id = "vpc-7xvsw3jjadaf53zjlido6"
name = "tf_test_foo"
route_table_id = "vtb-7xvjpppz3q8kin5vi081k"
router_id = "vrt-7xvi5nvfqmvg0mox9rj5j"
router_table_id = "vtb-7xvjpppz3q8kin5vi081k"
secondary_cidr_blocks = []
status = "Available"
user_cidrs = []
vpc_name = "tf_test_foo"
}
# alicloud_vswitch.vsw:
resource "alicloud_vswitch" "vsw" {
availability_zone = "cn-guangzhou-b"
cidr_block = "172.16.0.0/21"
id = "vsw-7xvwa2oq0fsjm3xuhv9ss"
status = "Available"
vpc_id = "vpc-7xvsw3jjadaf53zjlido6"
zone_id = "cn-guangzhou-b"
}
2 在上一步创建的专有网络中创建一个安全组，并添加一个允许任何地址访问的安全组规则。
在terraform.tf文件中增加以下内容。
resource "alicloud_security_group" "default" {
name = "default"
vpc_id = alicloud_vpc.vpc.id
}
resource "alicloud_security_group_rule" "allow_all_tcp" {
type = "ingress"
ip_protocol = "tcp"
nic_type = "intranet"
policy = "accept"
port_range = "1/65535"
priority = 1
security_group_id = alicloud_security_group.default.id
cidr_ip = "0.0.0.0/0"
}
运行terraform apply #开始创建。 有时time out 再来一次就好了
运行terraform show查看已创建的安全组和安全组规则。
您也可以登录ECS控制台查看安全组和安全组规则。
https://ecs.console.aliyun.com/?spm=5176.10483814.recommend.decs.78e6124322cN4j#/securityGroup/region/cn-guangzhou
3.创建ECS实例。
在terraform.tf文件中增加以下内容。
resource "alicloud_instance" "instance" {
# cn-beijing
availability_zone = "cn-beijing-b"
security_groups = alicloud_security_group.default.*.id
# series III 能找个最小的么 ecs.s6-c1m1.small
instance_type = "ecs.s6-c1m1.small"
#instance_type = "ecs.n2.small"
system_disk_category = "cloud_efficiency"
image_id = "ubuntu_18_04_64_20G_alibase_20190624.vhd"
instance_name = "test_foo"
vswitch_id = alicloud_vswitch.vsw.id
internet_max_bandwidth_out =10
password = "$Eevan2240881"
}
说明
在上述示例中，指定了internet_max_bandwidth_out= 10，因此会自动为实例分配一个公网IP。
详细的参数解释请参见
image_id 指定ubuntu_16_0402_32，最终会匹配ubuntu_16_0402_32_40G_alibase_20170711.vhd。
最终比较完整的配置文件
evan@myxps:~/.terraform.d$ cat terraform.tf
resource "alicloud_vpc" "vpc" {
vpc_name = "tf_test_foo"
cidr_block = "172.16.0.0/12"
}
resource "alicloud_vswitch" "vsw" {
vpc_id = alicloud_vpc.vpc.id
cidr_block = "172.16.0.0/21"
zone_id = "cn-guangzhou-b"
}
resource "alicloud_security_group" "default" {
name = "default"
vpc_id = alicloud_vpc.vpc.id
}
resource "alicloud_security_group_rule" "allow_all_tcp" {
type = "ingress"
ip_protocol = "tcp"
nic_type = "intranet"
policy = "accept"
port_range = "1/65535"
priority = 1
security_group_id = alicloud_security_group.default.id
cidr_ip = "0.0.0.0/0"
}
#ec2 create
resource "alicloud_instance" "instance" {
# cn-beijing
availability_zone = "cn-guangzhou-b"
security_groups = alicloud_security_group.default.*.id
# series III 能找个最小的么 ecs.s6-c1m1.small
instance_type = "ecs.s6-c1m1.small"
#instance_type = "ecs.n2.small"
system_disk_category = "cloud_efficiency"
image_id = "centos_7_9_x64_20G_alibase_20201228.vhd"
instance_name = "test_foo"
vswitch_id = alicloud_vswitch.vsw.id
internet_max_bandwidth_out =10
password = "$1234567890"
}
用Module创建多台ECS实例。在本示例中，创建3台ECS实例。 https://help.aliyun.com/document_detail/95830.html?spm=a2c4g.11186623.6.550.17317c8cNSSlJu

NOTES 将秘钥直接填入到.tf文件中是十分不安全的，在多用户共同管理资源时，不建议把腾讯云API 的秘钥直接写到源代码里，以免一不小心更新到公开的版本中，造成安全风险。
腾讯云提供了另一种更为安全可靠的方式，把秘钥信息放在环境变量中配置
// Configure the secret key in the environment path
$ export TENCENTCLOUD_SECRET_ID="your_fancy_accessid"
$ export TENCENTCLOUD_SECRET_KEY="your_fancy_accesskey"
$ export TENCENTCLOUD_REGION="ap-hongkong"
这样在 provider.tf 文件中就可以省略掉相关信息
$ vim provider.tf
// provider.tf
provider "tencentcloud" {}

terraform local
ocal 局部变量可以引用variable，resource，data中的一些资源属性，从而拼接改造需要的样式以供一起资源引用，local比variable更灵活，但local不能从外部来赋值。 局部值可能有助于避免在配置中多次重复相同的值或表达式，但是如果过度使用局部值，也可能通过隐藏使用的实际值而使以后的维护人员难以读取配置。 仅在某些地方使用单个值或结果且将来可能会更改该值的情况下，才应适度使用局部值。易于在中心位置更改值的能力是本地值的主要优势。

proxmox
1. Proxmox-Provider
目前社区主要有两个 provider:
Telmate/terraform-provider-proxmox: 用户最多，但是只支持管理虚拟机资源。
danitso/terraform-provider-proxmox: stars 少，但是可以管理 PVE 的大部分资源，包括节点、用户、资源池、TLS证书等等。
代码更顺眼，但是作者忙，没时间合并 pr，导致 Bug 更多一些。
不能设置虚拟机开机自启(onboot)，而且目前不支持 disk resize
