GitHub Action to Sync S3 Bucket 🔄

⚠️ Note: To use this action, you must have access to the GitHub Actions feature. GitHub Actions are currently only available in public beta. You can apply for the GitHub Actions beta here.

This simple action uses the vanilla AWS CLI to sync a a remote S3 bucket (or specific files) to a local directory.

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)
DEST_DIR	The local dir you wish to sync. For example, data.	env	No	No default
