Premiers pas avec MiniShift

Voici mes 1ers pas avec MiniShift, la version simple et légère de OpenShift RedHat à installer sur son Windows 10. J’ai déjà quelques VM sous VirtualBox. Je vais donc continuer avec cette contrainte.

Je vais juste vérifier que la plateforme s’exécute correctement avec une application JEE (on ne se refait pas) de démonstration.

Étapes:

  1. Téléchargement sur https://github.com/minishift/minishift/releases
  2. Je l’ai décompressé dans c:\Redhat\MiniShift
  3. 1er Lancement
minishift start --vm-driver=virtualbox
Starting local OpenShift cluster using 'virtualbox' hypervisor...

L’installation ne bouge pas 🙁 . Alors, un petit RAZ est nécessaire:

minishift delete
Deleting the Minishift VM...
Minishift VM deleted.

Et suppression du répertoire .minishift/ du profile Windows.

4. 2nd lancement. C’est mieux 🙂

minishift.exe start --vm-driver virtualbox -v 5 --show-libmachine-logs
Starting local OpenShift cluster using 'virtualbox' hypervisor...

5. Ajout de l’outil de commande en ligne OC dans le PATH Windows.

set OC_HOME=C:\Users\emman\.minishift\cache\oc\v1.4.1
set PATH=%PATH%;%OC_HOME%

6. Déploiement de l’application JEE de démo

L’application jee-ex est bien référencée et déployée.

La plateforme OpenShift via MiniShift fonctionne bien. Je vais pouvoir passer à la marche supérieure 😀 .
