Terraform: provisioner couldn't be found

Question

I have resource "aws_instance" "webserver" in my .tf file which contains provisioner "install-apache":

    provider "aws" {
      access_key = "ACCESS_KEY"
      secret_key = "SECRET-KEY"
      region     = "us-east-1"
    }

    resource "aws_instance" "webserver" {
      ami           = "ami-b374d5a5"
      instance_type = "t2.micro"

      provisioner "install-apache" {
        command = "apt-get install nginx"
      }
    }

After running terraform plan I've got an error:

     * aws_instance.webserver: provisioner install-apache couldn't be found

According to the terraform documentation everything looks fine.

Answer 1

The provisioner value must be one of the following:

• chef
• file
• local-exec
• remote-exec

I believe in your case you want the remote-exec value

provider "aws" {
  access_key = "ACCESS_KEY"
  secret_key = "SECRET-KEY"
  region     = "us-east-1"
}

resource "aws_instance" "webserver" {
  ami           = "ami-b374d5a5"
  instance_type = "t2.micro"

  provisioner "remote-exec" {
    inline = [
      "apt-get install nginx"
    ]
  }
}
