How to Install Packages on Remote Systems With Ansible

We will use Ansible to deploy packages to remote systems and in this case all the remote systems are running Debian, therefore we will be using the APT package manager.

Pre-Requisites:

Ensure that you have installed Ansible and setup the SSH Config for your remote systems, how to do that can be found under the post: setting up ansible

Our Inventory

Playbook

packages.yml

- hosts: all
  tasks:
  - name: Install Packages
    apt: name= state=latest update_cache=yes
    with_items:
      - ntp
      - python
      - tcpdump
      - wget
      - openssl
      - curl
