DBInstance

Source: src/AWS/RDS/DBInstance.ts

An RDS database instance — either a standalone (non-Aurora) database or a member of an Aurora DBCluster.

Exposes the full storage, backup, monitoring, performance-insights, encryption, networking, and log-export surface of createDBInstance / modifyDBInstance. Mutable fields are reconciled in place against the observed cloud state; immutable fields (engine, dbName, masterUsername, availabilityZone, storageEncrypted, kmsKeyId, dbSubnetGroupName) force a replacement.

Standalone Instance

const db = yield* DBInstance("Db", {
  engine: "mysql",
  dbInstanceClass: "db.t3.micro",
  allocatedStorage: 20,
  storageType: "gp3",
  masterUsername: "admin",
  masterUserPassword: Redacted.make("supersecret"),
  backupRetentionPeriod: 7,
  deletionProtection: false,
});

Cluster Member

const writer = yield* DBInstance("Writer", {
  dbClusterIdentifier: cluster.dbClusterIdentifier,
  dbInstanceClass: "db.serverless",
  engine: "aurora-postgresql",
});

Monitoring & Logs

const db = yield* DBInstance("Db", {
  engine: "postgres",
  dbInstanceClass: "db.t3.micro",
  allocatedStorage: 20,
  monitoringInterval: 60,
  monitoringRoleArn: monitoringRole.roleArn,
  enablePerformanceInsights: true,
  enableCloudwatchLogsExports: ["postgresql", "upgrade"],
});
