UCP Backup Container

A container to be used in an Docker EE environment. It runs a scheduled backup through cron and uploads the backup tar file to an S3 bucket.

Getting started

Clone the git repo

git clone https://github.com/pvdbleek/ucp-backup

Adjust the Dockerfile

The default schedule in the Dockerfile is every night at 1.10AM. You might want to adjust that to your preferred time.

Build & push the image

docker build -t <namespace>/<repository> .

docker push <namespace>/<repository>

Deploy AWS S3 credentials to Docker Swarm secrets

Assuming you know how to set up an S3 bucket and IAM access: Create two secrets in swarm:

echo <your_aws_access_key> | docker secret create aws_access_key -

echo <your_aws_secret_key> | docker secret create aws_secret_key -

Deploy ucp-backup as a swarm service

Make sure to use the following constraint: node.role==manager

Bind mount the Docker socket on: /var/run/docker.sock

Mount /etc/localtime to the container so that we use the same timezone as the host.

Expose the following two environment variables to your service:

AWS_REGION = <the_aws_region_your_s3_account_lives>

AWS_BUCKET = <the_name_of_your_s3_bucket>
