Construct to create a private asset S3 bucket. A cognito token can be used to allow access to he S3 asset.
Project description
cdk-private-asset-bucket
A construct to create a private asset S3 bucket. Cognito will be used for token validation with Lambda@Edge.
Architecture
Example
import { ProwlerAudit } from 'cdk-prowler';
...
const app = new core.App();
const stack = new core.Stack(app, 'PrivateAssetBucket-stack2', {
env: {
account: '981237193288',
region: 'us-east-1',
},
});
const userPool = new cognito.UserPool(stack, 'userPool', {
removalPolicy: core.RemovalPolicy.DESTROY,
});
const userPoolWebClient = new cognito.UserPoolClient(stack, 'userPoolWebClient', {
userPool: userPool,
generateSecret: false,
preventUserExistenceErrors: true,
authFlows: {
adminUserPassword: true,
userPassword: true,
},
oAuth: {
flows: {
authorizationCodeGrant: false,
implicitCodeGrant: true,
},
},
});
const privateAssetBucket = new PrivateAssetBucket(stack, 'privateAssetBucket', {
userPoolId: userPool.userPoolId,
userPoolClientId: userPoolWebClient.userPoolClientId,
});
new core.CfnOutput(stack, 'AssetBucketName', {
value: privateAssetBucket.assetBucketName,
});
new core.CfnOutput(stack, 'AssetBucketCloudfrontUrl', {
value: privateAssetBucket.assetBucketCloudfrontUrl,
});
Properties
Test PrivateBucketAsset
If you forged / cloned that repo you can test directly from here. Don't forget to init with:
yarn install
Create a test cdk stack with one of the following:
yarn cdk deploy
yarn cdk deploy --watch
yarn cdk deploy --require-approval never
- Upload a picture named like pic.png to the private asset bucket
- Create a user pool user and get / save the token:
USER_POOL_ID=us-east-1_0Aw1oPvD6
CLIENT_ID=3eqcgvghjbv4d5rv32hopmadu8
USER_NAME=martindev
USER_PASSWORD=M@rtindev1
REGION=us-east-1
CFD=d1f2bfdek3mzi7.cloudfront.net
aws cognito-idp admin-create-user --user-pool-id $USER_POOL_ID --username $USER_NAME --region $REGION
aws cognito-idp admin-set-user-password --user-pool-id $USER_POOL_ID --username $USER_NAME --password $USER_PASSWORD --permanent --region $REGION
ACCESS_TOKEN=$(aws cognito-idp initiate-auth --auth-flow USER_PASSWORD_AUTH --client-id $CLIENT_ID --auth-parameters USERNAME=$USER_NAME,PASSWORD=$USER_PASSWORD --region $REGION | jq -r '.AuthenticationResult.AccessToken')
echo "curl --location --request GET "https://$CFD/pic.png" --cookie "Cookie: token=$ACCESS_TOKEN""
- You can use the curl for importing in Postman. but it looks like Postman can't import the cookie. So you need to set the cookie manually in Postman!
- In Postman you should see your picture :)
Planned Features
- Support S3 bucket import ootb.
- Support custom authorizer
