clean-docker

Written by Devon Mack 2017-02-24

This program will delete all docker dangling volumes and dangling images. In addition it will delete all stopped containers and data only containers

Prerequisites:

• Up to date version of Docker
• Cron, installed and running (should be automatic)
• The user must have permissions to run Docker commands without sudo

Installation

Clone the github repository:

git clone https://github.com/devonpmack/clean-docker.git

Make the script executable with:

chmod 755 cleanDocker.sh

Run the script:

./cleanDocker.sh

A config.dat file will be created, edit the file and change it so it only includes the folder you want your logs to be stored in.

eg. /home/me/CleanDockerLogs/

---

Setting the program up as a cron job

Edit the cron config file through your terminal:

sudo crontab -e

Add this line to the bottom of the file (must have return character after):

0 7 * * 1 PATH_TO_SCRIPT

This setup will make it run every Monday at 7:00 AM.

Parameter Number	Parameter (* means it doesn't matter when)

2	Hour (0 - 23)
3	Day of month (1 - 31)
4	Month (1 - 12)
5	Day of week (0 - 7) (where both 0 and 7 mean Sun, 1 = Mon, 2 = Tue, etc)
