Le partage de volume se fait-il uniquement au sein d'un pod ?

Non, on peut aussi partager un volume entre plusieurs pods !

S'il s'agit de plusieurs pods sur la même machine, on peut utiliser un volume de type hostPath. Il y a un exemple dans le manifest [hacktheplanet.yaml][htp], qui permet à un pod d'accéder au répertoire /root du node. (Ce qui permet alors d'y injecter une clé SSH pour prendre la main en root sur le node... Et oui, côté sécurité, ça craint ! Pour s'en prémunir, on peut utiliser les mécanismes de contrôle d'admission, comme par exemple les Pod Security Settings ou bien un policy engine comme Kyverno - on verra ça dans "Kubernetes Avancé".)

Quiche recipe

I usually bake 2 quiches at a time; one vegetarian, one with the bacon, so the recipe here is for that.

For two quiches:

  • [two round doughs][dough]
  • some hazelnuts (maybe about 100g)
  • 6 eggs
  • [two becher of crème fraîche][cremefraiche]
  • 2 onions

# ... and display their PCI ID when available
# colorize output to highlight bus speeds maybe?
# add emojis to indicate device speeds?

# To deploy private clusters, uncomment the section below,

# Private clusters require extra resources (Cloud NAT,
# router, network, subnet) and the quota for some of these
# resources is fairly low on GCP; so if you want to deploy

Science Fiction written by women

Ann Leckie, "Ancillary Justice" (+2 sequels)

The AI of a powerful warship gets deprived from its thousands of eyes and hands, and still doesn't know which pronouns to use when interacting with others.

Ursula K. Le Guin, "The Dispossessed"

You can bannish communism to the dark side of the moon, but it will always come back when you least expect it.

Ursula K. Le Guin, "The Left Hand of Darkness"
