E-Mail notifications for docker-borgmatic

Description

This image adds e-mail notifications with msmtp to the docker-borgmatic container.

Usage

For general usage instructions see the README of the base image.

To setup e-mail notifications follow these steps:

• Add your mail relay details to the msmtp.env and place it in the borgmatic.d directory. See the list of environment variables below.
• Restart the container to apply the changes.

For those who update the image from v1.1.17-1.5.23 or below, you might want to migrate to the new e-mail notification script that provides you proper subject lines and adds further possibilities to use the environment for configuration:

• Remove the MAILTO from your crontab.txt.
• Edit your crontab.txt to match the upstream file.
• Extend the environment in msmtp.env to contain MAIL_TO and MAIL_SUBJECT.
