Docker Cleanup Script for Linux

What is this?

This is a Docker cleanup script for Linux, written in Bash. It deletes dead and exited containers, unused images, unused volumes and other docker trash.

Automated installation with Ansible

1. Clone the repository:

git clone https://github.com/LaggerIsME/docker-cleanup.git

2. Download and install the Ansible: https://docs.ansible.com/ansible/latest/installation_guide/installation_distros.html
3. Move to the ~/docker-cleanup/ansible/ directory:

cd docker-cleanup/ansible/ 

4. Copy the example.hosts to hosts:

cp example.hosts hosts

5. Configure variables in .hosts file:

test_server_1 ansible_host="192.168.122.58" ansible_user="test_sudo_user" ansible_become_password="testpassword" ansible_password="testpassword"
test_server_2 ansible_host="192.168.122.59" ansible_user="test_sudo_user2" ansible_become_password="testpassword2" ansible_password="testpassword2"

6. Activate ansible-playbook:

• With default hosts file:

ansible-playbook install-script.yml -i hosts

• With encrypted hosts file:

After all these actions, the script will clear your Linux every day at 01:00.
