This is intended to be a simple Docker image for retrieving an object from an S3 bucket. Under the hood, it uses s3cmd.
For example, to use it in a Systemd unit file to pull down some configuration file:
[Unit]
Description=custom-config
[Service]
Type=oneshot
ExecStart=/usr/bin/docker pull brandnetworks/s3-get ; /usr/bin/docker run --rm -it brandnetworks/s3-get bucket object > /path/to/file
[Install]
