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 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 optimal defaults for a static website are set in this example: --acl public-read makes your files publicly readable, --follow-symlinks won't hurt and fixes some weird symbolic link problems that may come up, and most importantly, --delete permanently deletes files in the S3 bucket that are not present in the latest version of your repository/build.

name: Sync Bucket
on: push

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:
        SOURCE_DIR: './public'
        AWS_REGION: 'us-east-1'
        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 }}

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.

Key	Value	Suggested Type	Required
AWS_ACCESS_KEY_ID	Your AWS Access Key. More info here.	secret	Yes
AWS_SECRET_ACCESS_KEY	Your AWS Secret Access Key. More info here.	secret	Yes
AWS_S3_BUCKET	The name of the bucket you're syncing to. For example, jarv.is.	secret	Yes
AWS_REGION	The region where you created your bucket in. For example, us-east-1. Full list of regions here.	env	Yes
SOURCE_DIR	The local directory you wish to sync/upload to S3. For example, ./public. Defaults to the root of your repository (.) if not provided.	env	No
