Terraform 自定义provider 开发

terraform init

Initializing provider plugins...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 plan

Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.------------------------------------------------------------------------An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
+ createTerraform will perform the following actions: + example_server.my-server
id: <computed>
address: "110.2.3.4"Plan: 1 to add, 0 to change, 0 to destroy.------------------------------------------------------------------------Note: You didn't specify an "-out" parameter to save this plan, so Terraform
can't guarantee that exactly these actions will be performed if
"terraform apply" is subsequently run.


terraform apply

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
+ createTerraform will perform the following actions: + example_server.my-server
id: <computed>
address: "110.2.3.4"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: yesexample_server.my-server: Creating...
address: "" => "110.2.3.4"
example_server.my-server: Creation complete after 0s (ID: 110.2.3.4)Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

terraform destroy

example_server.my-server: Refreshing state... (ID: 110.2.3.4)An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
- destroyTerraform will perform the following actions: - example_server.my-serverPlan: 0 to add, 0 to change, 1 to destroy.Do you really want to destroy all resources?
Terraform will destroy all your managed infrastructure, as shown above.
There is no undo. Only 'yes' will be accepted to confirm. Enter a value: yesexample_server.my-server: Destroying... (ID: 110.2.3.4)
example_server.my-server: Destruction complete after 0sDestroy complete! Resources: 1 destroyed.
