GCP Classroom Series – 10/Apr/2021 – Direct DevOps from Quality Thought

YAML tutorial Refer Here
As projects grow in size and complexity creating cloud resources manually or using a gcloud cli to create resources individually might not be a solution
In GCp there are several tool used for infrastructure managemetn which are collectively known as configuration management tools. These tool deliver value in the following areas
- Repeatability
- Transparency
- Testability
Declarative Configuration Management:
- Two primary approaches to infrastructure management are
  - imperative: how it has to be done
  - declarative: what has to be done
GCP Deployment manager is a declarative configuration management system.
The desired state is defined using configurations which are YAML files
The basic configuration file takes the following format

resources
  - name: <Resource_Name>
    type: <Resource_Type>
    properties:
      <key>: <value>

Refer Here for the official docs
In the documentation they use jinja which is closely related to yaml format
Resource types and properties
- This resource type defines the kind of the resource to be created. These resources include VMs, disk, netowork, BigQuery, AppEngine, Pub/Sub
- Manage base type takes the form of <API>.<VERSION>.<RESOURCE> eg compute.v1.instance
- Refer Here for the list of supported resource types
- Properties of the resource depends on the type used. Properties map directly to the types API representation.

Ensure Deployment Manager API is enabled for the project
Try to create a configuration to create a storage bucket Refer Here for the configuration created
Now deploy the configuration from gcloud for cli Refer Here
now lets update the deployment to create a new network
- Add the changes to the preview mode and the apply by executing update Refer Here for the changes done
Now delete the deployment
When we delete the deployment the resources created by the deployment will be deleted by deployment manager
