Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Within this repository, under the Chapter-8 folder, there is just one subfolder called terraform.”

A block of code is set as follows:

provider "google" {
  credentials = file("project-service-account-key.json")
  project = "autoscaling-simulation-lab"
  region  = "southamerica-east1"
  zone    = "southamerica-east1-a"
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

resource "google_compute_autoscaler" "foobar" {
...
  autoscaling_policy {
    max_replicas    = 5
    min_replicas    = 1
    cooldown_period = 60

Any command-line input or output is written as follows:

$ terraform init

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “To do this, we navigate to the Settings tab in our GitHub repository. Then select Secrets on the left side, and choose Actions.”
