GitHub Action to Sync S3 Bucket 🔄

This simple action uses the vanilla AWS CLI to sync a directory (either from your repository or generated during your workflow) with a remote S3 bucket.

Usage

`workflow.yml` Example

Place in a .yml file such as this one in your .github/workflows folder. Refer to the documentation on workflow YAML syntax here.

As of v0.3.0, all aws s3 sync flags are optional to allow for maximum customizability (that's a word, I promise) and must be provided by you via args:.

The following example includes optimal defaults for a public static website:

--acl public-read makes your files publicly readable (make sure your bucket settings are also set to public).
--follow-symlinks won't hurt and fixes some weird symbolic link problems that may come up.
Most importantly, --delete permanently deletes files in the S3 bucket that are not present in the latest version of your repository/build.
Optional tip: If you're uploading the root of your repository, adding --exclude '.git/*' prevents your .git folder from syncing, which would expose your source code history if your project is closed-source. (To exclude more than one pattern, you must have one --exclude flag per exclusion. The single quotes are also important!)

name: Upload Website

on:
  push:
    branches:
    - master

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - uses: jakejarvis/s3-sync-action@master
      with:
        args: --acl public-read --follow-symlinks --delete
      env:
        AWS_S3_BUCKET: ${{ secrets.AWS_S3_BUCKET }}
        AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
        AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        AWS_REGION: 'us-west-1'   # optional: defaults to us-east-1
        SOURCE_DIR: 'public'      # optional: defaults to entire repository

Configuration

The following settings must be passed as environment variables as shown in the example. Sensitive information, especially AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY, should be set as encrypted secrets — otherwise, they'll be public to anyone browsing your repository's source code and CI logs.

Key	Value	Suggested Type	Required	Default
`AWS_ACCESS_KEY_ID`	Your AWS Access Key. More info here.	`secret env`	Yes	N/A
`AWS_SECRET_ACCESS_KEY`	Your AWS Secret Access Key. More info here.	`secret env`	Yes	N/A
`AWS_S3_BUCKET`	The name of the bucket you're syncing to. For example, `jarv.is` or `my-app-releases`.	`secret env`	Yes	N/A
`AWS_REGION`	The region where you created your bucket. Set to `us-east-1` by default. Full list of regions here.	`env`	No	`us-east-1`
`AWS_S3_ENDPOINT`	The endpoint URL of the bucket you're syncing to. Can be used for VPC scenarios or for non-AWS services using the S3 API, like DigitalOcean Spaces.	`env`	No	Automatic (`s3.amazonaws.com` or AWS's region-specific equivalent)
`AWS_ASSUME_ROLE_ARN`	The arn of the role to assume.	env	No	N/A
`AWS_ROLE_SESSION_NAME`	An identifier for the assumed role session.	env	No	s3-sync
`SOURCE_DIR`	The local directory (or file) you wish to sync/upload to S3. For example, `public`. Defaults to your entire repository.	`env`	No	`./` (root of cloned repository)
`DEST_DIR`	The directory inside of the S3 bucket you wish to sync/upload to. For example, `my_project/assets`. Defaults to the root of the bucket.	`env`	No	`/` (root of bucket)
