There are a number of text conventions used throughout this book.
CodeInText: 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: "Note that the current_version property, which contains the latest Terraform version, is a value."
A block of code is set as follows:
TERRAFORM_VERSION=$(curl -s https://checkpoint-api.hashicorp.com/v1/check/terraform | jq -r .current_version)
....
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
FROM golang:latest
ENV TERRAFORM_VERSION=0.12.29
RUN apt-get update && apt-get install unzip \
&& curl -Os
Any command-line input or output is written as follows:
docker exec tfapp terraform init
docker exec tfapp terraform plan
docker exec tfapp terraform apply --auto-approve
Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Do this by clicking on the Install button of the extension."
