pragmatiks-gcp-provider 0.149.0

GCP provider for Pragmatiks

GCP Provider

Manage Google Cloud Platform resources declaratively through the Pragmatiks platform. This provider uses user-provided service account credentials (multi-tenant SaaS pattern) to create and manage GCP infrastructure.

Supported Services

Service	Resource	Description
Secret Manager	gcp/secret	Store and version sensitive data
GKE	gcp/gke	Kubernetes clusters (Autopilot and Standard)
Cloud SQL	gcp/cloudsql/database_instance	Managed database instances (PostgreSQL, MySQL, SQL Server)
Cloud SQL	gcp/cloudsql/database	Databases within a Cloud SQL instance
Cloud SQL	gcp/cloudsql/user	Database users within a Cloud SQL instance

Prerequisites

1. GCP Project with billing enabled.
2. Service account with appropriate IAM roles per resource:
   • Secret Manager: roles/secretmanager.admin
   • GKE: roles/container.admin
   • Cloud SQL: roles/cloudsql.admin
3. GCP APIs enabled on the project:
   • secretmanager.googleapis.com
   • container.googleapis.com
   • sqladmin.googleapis.com
   • logging.googleapis.com (for health checks and log streaming)
4. Service account key exported as JSON (passed via credentials field on each resource).

Installation

pragma providers install gcp

Resources

Secret (gcp/secret)

Manages secrets in GCP Secret Manager. Creates versioned secrets with automatic replication.

Config fields:

Field	Type	Required	Mutable	Description
project_id	string	yes	no	GCP project ID
secret_id	string	yes	no	Secret identifier (unique per project)
data	string	yes	yes	Secret payload to store
credentials	object/string	yes	yes	GCP service account credentials JSON

Outputs: resource_name, version_name, version_id

Example:

resources:
  - name: api-key
    provider: gcp
    type: secret
    config:
      project_id: my-gcp-project
      secret_id: api-key
      data: "sk-my-secret-value"
      credentials:
        $ref: gcp-credentials

Behavior:

• Create: Creates the secret and an initial version. Idempotent -- if the secret already exists, adds a new version.
• Update: Adds a new secret version when data changes. Previous versions are retained.
• Delete: Deletes the secret and all its versions.

---

GKE Cluster (gcp/gke)

Manages GKE clusters in either Autopilot (default) or Standard mode. Includes health checks and log streaming from Cloud Logging.

Config fields:

Field	Type	Required	Mutable	Default	Description
project_id	string	yes	no	--	GCP project ID
credentials	object/string	yes	yes	--	GCP service account credentials JSON
location	string	yes	no	--	Region or zone (e.g., europe-west4)
name	string	yes	no	--	Cluster name (lowercase, 1-40 chars)
autopilot	bool	no	no	true	Use Autopilot mode
network	string	no	no	"default"	VPC network name
subnetwork	string	no	yes	--	VPC subnetwork name
release_channel	string	no	yes	"REGULAR"	Release channel: RAPID, REGULAR, STABLE
initial_node_count	int	no	yes	1	Nodes in default pool (Standard only)
machine_type	string	no	yes	"e2-medium"	Node machine type (Standard only)
disk_size_gb	int	no	yes	100	Boot disk size in GB (Standard only)

Outputs: name, endpoint, cluster_ca_certificate, location, status, console_url, logs_url

Example (Autopilot):

resources:
  - name: prod-cluster
    provider: gcp
    type: gke
    config:
      project_id: my-gcp-project
      location: europe-west4
      name: prod-cluster
      autopilot: true
      release_channel: STABLE
      credentials:
        $ref: gcp-credentials

Example (Standard):

resources:
  - name: dev-cluster
    provider: gcp
    type: gke
    config:
      project_id: my-gcp-project
      location: europe-west4-a
      name: dev-cluster
      autopilot: false
      initial_node_count: 3
      machine_type: e2-standard-4
      disk_size_gb: 200
      credentials:
        $ref: gcp-credentials

Behavior:

• Create: Creates the cluster and polls until it reaches RUNNING state (up to 20 minutes). Idempotent -- if the cluster already exists, waits for RUNNING.
• Update: Returns current cluster state. Immutable fields (name, location, autopilot, network) require delete and recreate.
• Delete: Deletes the cluster and polls until fully removed.
• Health: Reports healthy (RUNNING), degraded (PROVISIONING/RECONCILING), or unhealthy (ERROR/not found).
• Logs: Streams cluster logs from Cloud Logging.

Cloud SQL Database Instance (gcp/cloudsql/database_instance)

      authorized_networks:
        - "10.0.0.0/8"
      credentials:
        $ref: gcp-credentials

Behavior:

• Create: Creates the instance and polls until RUNNABLE (up to 15 minutes). Generates a random root password. Idempotent.
• Update: Patches mutable settings (tier, availability, backups, network config) and waits for RUNNABLE.
• Delete: Deletes the instance. Respects deletion_protection -- disable it first to allow deletion.
• Health: Reports healthy (RUNNABLE), degraded (PENDING_CREATE/MAINTENANCE), or unhealthy.
• Logs: Streams instance logs from Cloud Logging.

Full Stack Example

A complete Cloud SQL setup with instance, database, user, and credentials stored in Secret Manager:

resources:
  - name: db-password
    provider: gcp
    type: secret
    config:
      project_id: my-gcp-project
      secret_id: db-password
      data: "my-secure-password"
      credentials:
        $ref: gcp-credentials

  - name: prod-instance
    provider: gcp
    type: cloudsql/database_instance
    config:
      project_id: my-gcp-project
      region: europe-west4
      instance_name: prod-postgres
      database_version: POSTGRES_15
      tier: db-custom-2-7680
      availability_type: REGIONAL
      backup_enabled: true
      credentials:
        $ref: gcp-credentials

  - name: app-db
    provider: gcp
    type: cloudsql/database
    config:
      instance:
        $ref: prod-instance
      database_name: myapp

  - name: app-user
    provider: gcp
    type: cloudsql/user
    config:
      instance:
        $ref: prod-instance
      username: app_service
      password: "my-secure-password"

Credentials

All resources require a credentials field containing GCP service account credentials as either a JSON object or a JSON string. In production, use a $ref to a secret resource to inject credentials securely.

The provider uses explicit credentials (not Application Default Credentials) to support multi-tenant deployments where each user operates in their own GCP project.
