Use the image as a non-root user

Running as a non-root user limits interaction with the Docker Daemon. If you want to stop and restart containers and services during backup, and the host’s Docker daemon is running as root, you will also need to run this tool as root.

By default, this image executes backups using the root user. In case you prefer to use a different user, you can use Docker’s user option, passing the user and group id:

docker run --rm \
  -v data:/backup/data \
  --env AWS_ACCESS_KEY_ID="<xxx>" \
  --env AWS_SECRET_ACCESS_KEY="<xxx>" \
  --env AWS_S3_BUCKET_NAME="<xxx>" \
  --entrypoint backup \
  --user 1000:1000 \
  offen/docker-volume-backup:v2

or in a compose file:

services:
  backup:
    image: offen/docker-volume-backup:v2
    user: 1000:1000
    # further configuration omitted ...
