Docker image to backup your Docker container volumes
Why the name? Docker + Backup = Dockup
You have a container running with one or more volumes:
$ docker run -d --name mysql tutum/mysql
From executing a $ docker inspect mysql
we see that this container has two volumes:
"Volumes": {
"/etc/mysql": {},
"/var/lib/mysql": {}
}
Launch dockup
container with the following flags:
$ docker run --rm \
--env-file env.txt \
--volumes-from mysql \
--name dockup borja/dockup
The contents of env.txt
being:
AWS_ACCESS_KEY_ID=<key_here>
AWS_SECRET_ACCESS_KEY=<secret_here>
AWS_DEFAULT_REGION=us-east-1
BACKUP_NAME=mysql
PATHS_TO_BACKUP=/etc/mysql /var/lib/mysql
S3_BUCKET_NAME=docker-backups.example.com
dockup
will use your AWS credentials to create a new bucket with name as per the environment variable S3_BUCKET_NAME
, or if not defined, using the default name docker-backups.example.com
. The paths in PATHS_TO_BACKUP
will be tarballed, gzipped, time-stamped and uploaded to the S3 bucket.
Bucket naming guidelines: "Bucket names must be unique and should be DNS compliant. Bucket names can contain lowercase letters, numbers, hyphens and periods. Bucket names can only start and end with a letter or number, and cannot contain a period next to a hyphen or another period."
These rules are enforced in some regions.

US West (Oregon) | us-west-2 |
