Este artículo propone automatizar la instalación de docker en Raspberry Pi a través de Ansible con un rol hecho a medida.
Requisitos previos
- Haber instalado Raspbian en el Raspberry Pi objetivo, el procedimiento está disponible en un artículo anterior Inicialización y securización automatizadas de Raspbian en Raspberry Pi
Instalación de Docker
Recuperación del rol
He desarrollado un rol ansible para esta automatización, aquí está cómo recuperarlo:
git clone https://gitlab.com/jls42/ansible-rpi-docker.git roles/ansible-rpi-docker
Para más detalles ir a ver la documentación en ansible-rpi-docker
Creación del archivo de inventario llamado inventory
En este ejemplo de inventario el Raspberry Pi posee la ip 192.168.1.190
[rpi1]
192.168.1.190 servername=rpi1
Preparación del playbook docker-rpi.yml
---
- name: "Installation de Docker sur le Raspberry Pi"
hosts: rpi1
remote_user: "pi"
roles:
- roles/ansible-rpi-docker
vars:
docker_version: 18.06.1~ce~3-0~raspbian
Despliegue de Docker
export ANSIBLE_HOST_KEY_CHECKING=False
ansible-playbook -b -i inventory docker-rpi.yml
Lo que da:
jls42@boo:~/rpi$ ansible-playbook -b -i inventory docker-rpi.yml
