feat(aws-s3-deployment): bucket deployments (#971)
Browse files Browse the repository at this point in the history 
This new library allows deploying contents to S3 buckets as part of a CDK app from a .zip file in another bucket or from a local asset (directory or a .zip file).

This is how it's used:

    new BucketDeployment(this, 'DeployMe', {
      source: Source.asset('/local/directory'),
      destinationBucket: dest
    });

"source" can either be a local directory, a local zip file or another
bucket+key.

This library is backed by a custom CloudFormation resource which uses the
AWS CLI to invoke "aws s3 sync". 

By default, when the resource is deleted, the contents of the destination are deleted. The `RetainOnDelete` option can be used to disable this behavior.

Fixes #952.

Misc:
- Change travis CI environment to allow running python3 (as well as node.js).
- Add "!!!!!" markers when build/test fails so it will be easier to locate errors in build logs.

Future plans:

- The current version will always use "--delete" which means destination files will be deleted if they don't exist on the source (will be addressed in #953).
- Another mode of operation that we plan to add is blue/green deployments (#954).

## AWS S3 Deployment Construct Library

> __Status: Experimental__
This library allows populating an S3 bucket with the contents of a .zip file
from another S3 bucket or from local disk.

The following example defines a publicly accessible S3 bucket with web hosting
enabled and populates it from a local directory on disk.

```ts
const websiteBucket = new s3.Bucket(this, 'WebsiteBucket', {
websiteIndexDocument: 'index.html',
publicReadAccess: true
});

new s3deploy.BucketDeployment(this, 'DeployWebsite', {
source: s3deploy.Source.asset('./website-dist'),
destinationBucket: websiteBucket,
destinationKeyPrefix: 'web/static' // optional prefix in destination bucket
});
```

This is what happens under the hood:

1. When this stack is deployed (either via `cdk deploy` or via CI/CD), the
contents of the local `website-dist` directory will be archived and uploaded
to an intermediary assets bucket.
2. The `BucketDeployment` construct synthesizes a custom CloudFormation resource
of type `Custom::CDKBucketDeployment` into the template. The source bucket/key
is set to point to the assets bucket.
3. The custom resource downloads the .zip archive, extracts it and issues `aws
s3 sync --delete` against the destination bucket (in this case
`websiteBucket`).

## Supported sources

The following source types are supported for bucket deployments:

- Local .zip file: `s3deploy.Source.asset('/path/to/local/file.zip')`
- Local directory: `s3deploy.Source.asset('/path/to/local/directory')`
- Another bucket: `s3deploy.Source.bucket(bucket, zipObjectKey)`

## Retain on Delete

By default, the contents of the destination bucket will be deleted when the
`BucketDeployment` resource is removed from the stack or when the destination is
changed. You can use the option `retainOnDelete: true` to disable this behavior,
in which case the contents will be retained.

## Notes

* This library uses an AWS CloudFormation custom resource which about 10MiB in
size. The code of this resource is bundled with this library.
* AWS Lambda execution time is limited to 15min. This limits the amount of data which can
be deployed into the bucket by this timeout.
* When the `BucketDeployment` is removed from the stack, the contents are retained
in the destination bucket ([#952](https://github.com/awslabs/aws-cdk/issues/952)).
* Bucket deployment _only happens_ during stack create/update. This means that
if you wish to update the contents of the destination, you will need to
change the source s3 key (or bucket), so that the resource will be updated.
This is inline with best practices. If you use local disk assets, this will
happen automatically whenever you modify the asset, since the S3 key is based
on a hash of the asset contents.

## Development

The custom resource is implemented in Python 3.6 in order to be able to leverage
the AWS CLI for "aws sync". The code is under [`lambda/src`](./lambda/src) and
unit tests are under [`lambda/test`](./lambda/test).

This package requires Python 3.6 during build time in order to create the custom
resource Lambda bundle and test it. It also relies on a few bash scripts, so
might be tricky to build on Windows.

## Roadmap

- [ ] Support "progressive" mode (no `--delete`) ([#953](https://github.com/awslabs/aws-cdk/issues/953))
- [ ] Support "blue/green" deployments ([#954](https://github.com/awslabs/aws-cdk/issues/954))
