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: “Let’s try to raise a pull request for merging our code from the feature/feature1 branch to the master branch.”

A block of code is set as follows:

import os
import datetime
from flask import Flask
app = Flask(__name__)
@app.route('/')
def current_time():
  ct = datetime.datetime.now()
  return 'The current time is : {}!\n'.format(ct)
if __name__ == "__main__":
  app.run(debug=True,host='0.0.0.0')

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

$ cp ~/modern-devops/ch13/install-external-secrets/app.tf \
terraform/app.tf
$ cp ~/modern-devops/ch13/install-external-secrets/\
external-secrets.yaml manifests/argocd/ 

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Click on the Create pull request button to create the pull request.”
