packer-template

Ansible role to generate Packer templates using YAML and Jinja2.

Due to limitations of JSON, Packer templates contain a lot of code duplication. Flexibility of YAML and Jinja2, helps to reduce the duplication.

Requirements

No requirements for executing the module.

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) edge"
sudo apt update
sudo apt install -y docker-ce
sudo pip install docker-py

sudo systemctl edit docker
#[Service]
