As you asked, for example, there is a limit on the comment, so posting as the answer using local-exec
.
I assume that you already configure aws configure | aws configure --profile test
using aws-cli.
Here is the complete example to reboot an instance, change VPC SG ID, subnet and key name etc
provider "aws" {
region = "us-west-2"
profile = "test"
}
resource "aws_instance" "ec2" {
ami = "ami-0f2176987ee50226e"
instance_type = "t2.micro"
associate_public_ip_address = false
subnet_id = "subnet-45454566645"
vpc_security_group_ids = ["sg-45454545454"]
key_name = "mytest-ec2key"
tags = {
Name = "Test EC2 Instance"
}
}
resource "null_resource" "reboo_instance" {
provisioner "local-exec" {
on_failure = "fail"
interpreter = ["/bin/bash", "-c"]
command = <<EOT
echo -e "\x1B[31m Warning! Restarting instance having id ${aws_instance.ec2.id}.................. \x1B[0m"
# aws ec2 reboot-instances --instance-ids ${aws_instance.ec2.id} --profile test
# To stop instance
aws ec2 stop-instances --instance-ids ${aws_instance.ec2.id} --profile test
echo "***************************************Rebooted****************************************************"
EOT
}
# this setting will trigger script every time,change it something needed
triggers = {
always_run = "${timestamp()}"
}
}
Now Run terraform apply
Once created and you want later to reboot or stop just call
terraform apply -target null_resource.reboo_instance
