What is the first step to post a message within a Pub/Sub topic?

Containers are being created and managed across multiple projects in Google Cloud. A requirement for the application under development is to access Google Cloud services from within Google Kubernetes Engine (GKE).

What actions are recommended?

An application is being managed on a Compute Engine instance, alongside multiple backend services that are run on stand-alone Docker containers in Compute Engine instances. These Compute Engine instances supporting the backend services are scaled by managed instance groups across several regions. In order to ensure a loosely coupled calling application, it is necessary to be able to invoke individual service implementations which are selected based on the value of an HTTP header located within the request.

What is the appropriate Google Cloud feature to activate the backend services?

A stateless web application for a marquee is being developed for Google Cloud. It is expected that the incoming user traffic will be unpredictable, with some days having no traffic while other days will have large spikes. The application should be able to automatically scale up and down, while minimizing the cost associated with running the application.

What actions do you need to take?

Your application is deployed in a Google Kubernetes Engine (GKE) cluster. When a new version of your application is released, your CI/CD tool updates the spec.template.spec.containers[0].image value to reference the Docker image of your new application version. When the Deployment object applies the change, you want to deploy at least 1 replica of the new version and maintain the previous replicas until the new replica is healthy. Which change should you make to the GKE Deployment object shown below?
