What is it

This Dockerfile (available as servercontainers/dirvish) gives you a Dirvish Backup System in a container.

Backup System in Container
- runs at a specific time in infinite loop
Standalone Backup
- container exits after backup is done
- good if triggered from external cronjob etc.

For Configuration of the Server you use environment Variables and volume files.

It's based on the debian:jessie Image

View in Docker Registry servercontainers/dirvish

View in GitHub ServerContainers/dirvish

Environment variables

STANDALONE
- if this variable is set to any value the container stops after the backup is done
- default not set
TZ
- specify the timezone inside the container
- default Europe/Berlin
CRONTIME
- overwrite default crontime with your one
- default 30 4 * * *

Volumes

/config
- this is where the container looks for:
  - master.conf (dirvish main configuration file - see example or official manual)
  - id_rsa (ssh private key to connect to backup-clients/servers)
    - don't forget to specify it inside master.conf
  - ida_rsa.pub (ssh public key - not needed - only on clients)
/backups
- this is where the container stores backups and looks for backup-client configurations
- default layout beneath this folder: bank/backup/dirvish/default.conf

Take a look at the GitHub Repo, you'll find a example there.

Cheat Sheet

SSH Key generation

To connect to your hosts, you need to install a ssh keypair on them. This keypair should be moved to the config folder of the container. Don't forget to specify it in the master.conf as well!

To generate a keypair just execute ssh-keygen -t rsa and follow the instructions. You'll find your keypair beneath ~/.ssh.

Now install the public keys on the servers you want to backup, and the private key on this container.
