⁠Usage

docker run -d [OPTIONS] channelape/s3-sync

⁠Required Parameters:

• -e KEY=<KEY>: User Access Key
• -e SECRET=<SECRET>: User Access Secret
• -e REGION=<REGION>: Region of your bucket
• -e BUCKET=<BUCKET>: The name of your bucket
• -v /path/to/backup:/data:ro: mount target local folder to container's data folder. Content of this folder will be synced with S3 bucket.

⁠Optional parameters:

• no-cron: run container once and exit (no cron scheduling).

⁠Examples:

Sync every hour with cron schedule (container keeps running):

docker run -d \
    -e KEY=mykey \
    -e SECRET=mysecret \
	-e REGION=region \
    -e BUCKET=mybucket \
    -e CRON_SCHEDULE="0 * * * *" \
	-e BUCKET_PATH=/path \
    -v /home/user/data:/data:ro \
    channelape/s3-sync

Sync just once (container is deleted afterwards):

docker run --rm \
    -e KEY=mykey \
    -e SECRET=mysecret \
	-e REGION=region \
    -e BUCKET=mybucket \
    -v /home/user/data:/data:ro \
    channelape/s3-sync no-cron

⁠Credits

This container is heavily inspired by istepanov/backup-to-s3⁠.

The main difference is that this container is using Alpine Linux instead of Debian to be more light weight. It also uses a different method of using the AWS CLI tool.
