يقترح هذا المقال أتمتة تثبيت Kubernetes 1.13 على Raspberry Pi عبر Ansible مع دور مصنوع يدويًا.
المتطلبات
- يجب أن تكون قد قمت بتثبيت Raspbian على Raspberry Pi المستهدف (على الأقل 2)، الإجراء متاح في مقال سابق تهيئة وتحصين تلقائي لـ Raspbian على Raspberry Pi
تثبيت Docker + Kubernetes
استرداد الدور
لقد طورت دور ansible لهذا الأتمتة، إليك كيفية استرداده:
## Pré-requis Docker (rôle fait maison)
git clone https://gitlab.com/jls42/ansible-rpi-docker.git roles/ansible-rpi-docker
## Rôle pour l'installation de Kubernetes
git clone https://gitlab.com/jls42/ansible-rpi-k8s.git roles/ansible-rpi-k8s
لمزيد من التفاصيل، اذهب إلى المستندات على ansible-rpi-k8s
إنشاء ملف الجرد المسمى inventory
في هذا المثال للجرد عدة Raspberry Pi 1، أحدهم يحمل IP 192.168.1.190 والآخر يحمل IP 192.168.1.191
في المجموعة الفرعية (هنا rpi-k8s)، يجب تعيين الماستر أولاً
[rpi1]
192.168.1.190 k8s_master=true
[rpi2]
192.168.1.191
[rpi-k8s:children]
rpi1
rpi2
تحضير playbook المسمى k8s-rpi.yml
---
- name: "Installation de Docker sur le Raspberry Pi"
hosts: rpi-k8s
remote_user: "pi"
roles:
- roles/ansible-rpi-docker
vars:
docker_version: 18.06.1~ce~3-0~raspbian
- name: "Installation de k8s sur le Raspberry Pi"
hosts: rpi-k8s
remote_user: "pi"
roles:
- roles/ansible-rpi-k8s
vars:
k8s_version: "1.13.0-00"
k8s_master_token: "abcdef.0123456789abcdef"
k8s_cluster_group: rpi-k8s
نشر Docker و Kubernetes
سيتم تشغيل الأدوار ansible-rpi-docker و ansible-rpi-k8s على التوالي.
في حالة كان docker مثبتًا بالفعل، يمكن تشغيل ansible-rpi-k8s فقط.
export ANSIBLE_HOST_KEY_CHECKING=False
ansible-playbook -b -i inventory k8s-rpi.yml
ما ينتج عنه:
jls42@boo:~/rpi$ ansible-playbook -b -i inventory k8s-rpi.yml
