DatabaseInstanceBase L2 construct ​

A new or imported database instance.

Example ​

ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_ec2 as ec2 } from 'aws-cdk-lib';
import { aws_rds as rds } from 'aws-cdk-lib';

declare const instanceEngine: rds.IInstanceEngine;
declare const securityGroup: ec2.SecurityGroup;
const databaseInstanceBase = rds.DatabaseInstanceBase.fromDatabaseInstanceAttributes(this, 'MyDatabaseInstanceBase', {
  instanceEndpointAddress: 'instanceEndpointAddress',
  instanceIdentifier: 'instanceIdentifier',
  port: 123,

Construct Props ​

accountstringaccountstraccountStringAccountstringAccount*string= the resource is in the same acco…#
The AWS account ID this resource belongs to.
default

Default: the resource is in the same account as the stack it belongs to

environmentFromArnstringenvironment_from_arnstrenvironmentFromArnStringEnvironmentFromArnstringEnvironmentFromArn*string= take environment from `account`,…#
ARN to deduce region and account from.

The ARN is parsed and the account and region are taken from the ARN. This should be used for imported resources.

Cannot be supplied together with either account or region.

default

Default: take environment from account, region parameters, or use Stack environment.

The value passed in by users to the physical name prop of the resource.
notes · default
  • undefined implies that a physical name will be allocated by CloudFormation during deployment.
  • a concrete value implies a specific physical name
  • PhysicalName.GENERATE_IF_NEEDED is a marker that indicates that a physical will only be generated by the CDK if it is needed for cross-environment references. Otherwise, it will be allocated by CloudFormation.

Default: The physical name will be allocated by CloudFormation at deployment time

The AWS region this resource belongs to.
default

Default: the resource is in the same region as the stack it belongs to

May be not known for imported Instances if it wasn't provided explicitly, or for read replicas.

The environment this resource belongs to.
notes

For resources that are created and managed in a Stack (those created by creating new class instances like new Role(), new Bucket(), etc.), this is always the same as the environment of the stack they belong to.

For referenced resources (those obtained from referencing methods like Role.fromRoleArn(), Bucket.fromBucketName(), etc.), they might be different than the stack they were imported into.

Methods ​

addProxy(id: string, options: DatabaseProxyOptions): DatabaseProxydef add_proxy(self, id: str, options: DatabaseProxyOptions) -> DatabaseProxypublic DatabaseProxy addProxy(String id, DatabaseProxyOptions options)public DatabaseProxy AddProxy(string id, DatabaseProxyOptions options)func AddProxy(Id *string, Options DatabaseProxyOptions) DatabaseProxy#

applyCrossStackReferenceStrength(strength: ReferenceStrength): voiddef apply_cross_stack_reference_strength(self, strength: ReferenceStrength) -> Nonepublic void applyCrossStackReferenceStrength(ReferenceStrength strength)public void ApplyCrossStackReferenceStrength(ReferenceStrength strength)func ApplyCrossStackReferenceStrength(Strength ReferenceStrength)#
Override the cross-stack reference strength for this resource.
notes · 1 parameter

When set, any cross-stack reference to this resource will use the specified mechanism instead of the global default determined by the @aws-cdk/core:defaultCrossStackReferences context key. This is useful for selectively weakening specific references to avoid the "deadly embrace" problem without changing the app-wide default.

Parameters

  • strengthstrengthstrengthstrengthStrength — - The reference strength to use for this resource.
applyRemovalPolicy(policy: RemovalPolicy): voiddef apply_removal_policy(self, policy: RemovalPolicy) -> Nonepublic void applyRemovalPolicy(RemovalPolicy policy)public void ApplyRemovalPolicy(RemovalPolicy policy)func ApplyRemovalPolicy(Policy RemovalPolicy)#
Apply the given removal policy to this resource.
notes

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Checks if `x` is a construct.
notes · 1 parameter · returns

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters

  • xxxxX — Any object.

Returns: true if x is an object created from a class which extends Construct.

Mixins are applied in order. The list of constructs is captured at the start of the call, so constructs added by a mixin will not be visited. Use multiple with() calls if subsequent mixins should apply to added constructs.
