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: “Something that changed from the previous EC2 Windows-based task is that Fargate uses awsvpc; thereby, we need to add the proper porting mappings.”

A block of code is set as follows:

resource "aws_alb_listener" "ecs_alb_listener" {
  load_balancer_arn = aws_lb.ecs_alb.arn
  port              = 80
  protocol          = "HTTP"

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

apiVersion: node.k8s.io/v1 
kind: RuntimeClass 
metadata: 
   name: windows-2019 
handler: 'docker'

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

terraform init
terraform apply

Bold: Indicates a new term, an important word, or words that you see onscreen. Here is an example: “Assuming you have two Kubernetes deployments, Deployment 1 deploys the frontend, and Deployment 2 deploys the backend.”
