docker-unattended-upgrade

Ubuntu image with daily unattended upgrade for security updates.

The image simply installs unattended-upgrade and supervisor with two simple scripts:

1. install to configure supervisor to run cron
2. start adds a cron job to call unattended-upgrade and start supervisor

This only to ensure that security updates are installed automatically in production untill a new update docker image is pushed and deployed with latest security updates.

The image can be pulled from docker hub directly

docker run itech/base-unattended-upgrade

or used as a base image by defining the Dockerfile as following

FROM itech/base-unattended-upgrade
# Rest of your Dockerfile
