Parameters:

sync, get, or del: subcommand to pass to s3cmd
-e ACCESS_KEY=<AWS_KEY>: Your AWS key.
-e SECRET_KEY=<AWS_SECRET>: Your AWS secret.
-e S3_PATH=s3://<BUCKET_NAME>/<PATH>/: S3 Bucket name and path. Should end with trailing slash.

Examples:

Run once to sync files in /home/user/data to S3:

docker run --rm \
    -e ACCESS_KEY=myawskey \
    -e SECRET_KEY=myawssecret \
    -e S3_PATH=s3://my-bucket/backup/ \
    -v /home/user/data:/data:ro \
    hemberger/docker-backup-to-s3 sync

Run once to get file from S3:

docker run --rm \
    -e ACCESS_KEY=myawskey \
    -e SECRET_KEY=myawssecret \
    -e S3_PATH=s3://my-bucket/backup/ \
    -v /home/user/data:/data:rw \
    hemberger/docker-backup-to-s3 get

Run once to delete files from S3:

docker run --rm \
    -e ACCESS_KEY=myawskey \
    -e SECRET_KEY=myawssecret \
    -e S3_PATH=s3://my-bucket/backup/ \
    hemberger/docker-backup-to-s3 del

Security considerations: on restore, this opens up permissions on the restored files widely.
