Environnement de travail - DevOps​

  1. Ansible
  2. Vagrant
  3. Docker
  4. Kubernetes

Ansible​

  • 1 VM - Une machine master - (Ansible, Vagrant, Docker)
    • Sur laquelle sera installé
    • Soit une machine virtuelle - Soit WSL
  • 1 VM - Une machine cliente
    • Pour les déploiement

Obligation pour l'hyperviseur :

  • Un sous réseau qui a accès à internet mais qui n'est pas votre réseau local
    • NAT (workstation)
    • Réseau NAT (VirtualBox) - Redirection de port pour SSH

Pasted image 20230221160046.png IP Fixe sur les 2 machines SSH installé et configuré

Pour vérifier :​

  1. ping du master jusqu'au client
  2. connexion ssh
    1. ssh root@(ipduclient)
  3. Echange de clef puis re tester pour vérifier si on peut se connecter sans le mot de passe

ssh depuis le master vers le client (Sans mot de passe - Donc échange de clef) Création de la clef : ssh-keygen -a rsa ssh-copy-id root@(IP DU CLIENT)
