This is a submission for the Pulumi Deploy and Document Challenge: Shhh, It's a Secret!

What I Built

A secret management orchestrator using Pulumi ESC that:

  • Securely stores/rotates credentials across multiple cloud providers
  • Implements automatic encryption at rest/in transit
  • Enforces RBAC policies with least privilege access
  • Integrates with existing CI/CD pipelines
  • Provides audit logging for all secret operations

My Journey

The Challenge

Managing sensitive data across hybrid environments posed three critical problems:

  1. Credential Sprawl - Secrets scattered across 15+ services
  2. Rotation Complexity - Manual key rotation causing downtime
  3. Compliance Risks - Lack of audit trails for regulatory requirements

Pulumi ESC Solution 

# Python SDK example for secret rotation
from pulumi_aws import secretsmanager

def rotate_secret(secret_name: str):
    secret = secretsmanager.Secret(secret_name)

    # Automatic rotation configuration
    secret.rotate_configuration = secretsmanager.RotationConfigurationArgs(
        automatically_after_days=7,
        rotation_type="AWS_DEFAULT"
    )

    # Access policy with least privilege
    secret.access_policy = secretsmanager.AccessPolicyArgs(
        secret_id=secret.id,
        policy_document={
            "Version": "2012-10-17",
            "Statement": [{
                "Effect": "Allow",
                "Principal": {"AWS": f"arn:aws:iam::{aws.get_caller_identity().account_id}:root"},
                "Action": "secretsmanager:GetSecretValue",
                "Resource": "*"
            }]
        }
    )

Technical Implementation

(Sample flow: Application → Vault → Encrypted Storage → Audit Log)

Key Components

  1. Secret Provider Engine 
// Multi-cloud secret provider setup
import * as esc from "@pulumi/esc";

const secretsConfig = new esc.SecretsConfiguration("prod-secrets", {
    providers: {
        aws: { region: "us-west-2" },
        azure: { subscriptionId: "..." }
    }
});
  1. Automated Rotation Workflow 
# Sample CI/CD pipeline step
pulumi up --secrets-provider=aws-vault \
          --secret-rotation-policy=30d \
          --enable-audit-logging

Security Features

✅ Zero-Knowledge Encryption - Secrets encrypted client-side before storage

✅ Granular RBAC - Fine-grained access control through IAM integration

✅ Immutable Auditing - Write-once-read-many audit logs stored separately

✅ Automatic Key Phasing - Seamless transitions between encryption keys

Best Practices

  1. Secret Versioning 
# Python rotation example with versioning
secret_version = secret.latest_version
secret_version.enable_auto_rotation(
    rotation_type="AWS_DEFAULT",
    automatically_after_days=14
)
  1. Cross-Cloud Protection 
# Environment variable encryption
export DB_PASSWORD=$(pulumi config get aws:secretsmanager:db-password --secret)
  1. Disaster Recovery 
// Backup/restore configuration
const backup = new esc.SecretBackup("prod-backup", {
    secretArn: secret.arn,
    storageLocation: "s3://secure-backups-bucket"
});
