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: "We're doing two things in this command – first, we are running gcloud secrets versions access latest --secret=flask-app-secret to access the contents of the secret, and then we are piping it directly to kubectl apply -f -."

A block of code is set as follows:

...
    spec:
      containers:
        - image: '<your_docker_user>/flask-app-secret:1'
          name: flask-app
          ports:
            - containerPort: 5000
          env:
            - name: SECRET
              valueFrom:
                 secretKeyRef:
                   name: flask-app-secret
                   key: SECRET

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: "Click Flash from Etcher to write the image."

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

$ git clone https://github.com/PacktPublishing/Modern-DevOps-\
Practices.git modern-devops $ cd modern-devops/ch7
