Upgrade Docker Images

This bash script will automatically update all of your docker images.

It will also report which obsolete images cannot be removed because they have dependent child images, and what those children are.

Installation

I recommend placing this in /usr/sbin:

wget https://raw.githubusercontent.com/phpexpertsinc/DockerUpgrader/v1.0/docker-images-update
chmod 0750 docker-images-update
sudo chown root:docker docker-images-update
sudo cp docker-images-update /usr/sbin

Also, consider adding it to your daily scheduled tasks:

sudo cp docker-images-update /etc/cron.daily

Usage

docker-images-update

Use cases

✔ Keeps your third-party docker images up-to-date.
✔ Far less security worries when base images are updated.
✔ Points out which docker images could not be updated and are obsoleted.
