Is it not possible to create a postgres cloudsql via deployment manager?

Question

I've check in supported-gcp-types and supported-resource-types but I don't see any possibility at all

Answer 1

Deployment Manager supports PostgreSQL.

You need to specify the backendType as SECOND_GEN, databaseVersion as POSTGRES_9_6 and tier as db-custom-1-3840.

Documentation

Example (create-postgresql-instance.jinja):

{% set deployment_name = env['deployment']  %}
{% set instance_name = deployment_name + '-instance'  %}
{% set database_name = deployment_name + '-db'  %}
{% set region = 'us-central1'  %}
{% set tier = 'db-custom-1-3840'  %}

resources:
- name: {{ instance_name }}
  type: gcp-types/sqladmin-v1beta4:instances
  properties:
    region: {{ region }}
    backendType: SECOND_GEN
    databaseVersion: POSTGRES_9_6
    settings:
      tier: {{ tier }}
      backupConfiguration:
        enabled: true

- name: {{ database_name }}
  type: gcp-types/sqladmin-v1beta4:databases
  properties:
    name: {{ database_name }}
    instance: $(ref.{{ instance_name }}.name)
    charset: utf8

Deploy:

gcloud deployment-manager deployments create mydb --template create-postgresql-instance.jinja
