So we created an AWS EC2 instance. We omitted specifying the keys because the AWS API is already authorized and this authorization will be used by Terraform.
Also, for code use, Terraform supports variables, data, and modules.
Let's create a separate network:
resource "aws_vpc" "my_vpc" {
cidr_block = "190.160.0.0/16"
instance_target = "default"
}
resource "aws_subnet" "my_subnet" {
vpc_id = "$ {aws_vpc.my_vpc.id}"
cidr_block = "190.160.1.0/24"
}
$ cat gce / provider.tf
provider "google" {
credentials = "$ {file (" account.json ")}"
project = "my-project-id"
region = "us-central1"
}
resource "google_compute_instance" "default" {
name = "test"
machine_type = "n1-standard-1"
zone = "us-central1-a"
}
$ cd gce
$ terraform init
$ terraform apply
$ cd ..
For distributed work, let's put the state in AWS S3 the state of the infrastructure (you can also put other data), but for security in a different region:
terraform {
backend "s3" {
bucket = "tfstate"
key = "terraform.tfstate"
region = "us-state-2"
}
}
provider "kubernetes" {
host = "https://104.196.242.174"
username = "ClusterMaster"
password = "MindTheGap"
}
resource "kubernetes_pod" "my_pod" {
spec {
container {
image = "Nginx: 1.7.9"
name = "Nginx"
port {
container_port = 80
}
}
}
}
Commands:
terraform init # downloading dependencies according to configs, checking them
terraform validate # syntax check
terraform plan # to see in detail how the infrastructure will be changed and why exactly so, for example,
whether only the service meta information will be changed or the service itself will be re-created, which is often unacceptable for databases.
terraform apply # applying changes
The common part for all providers is the core.
