Editor's Notes

  • #6: Cosa succede con kernel differenti (es: windows e linux) se spostiamo I container da una parte all’altra? Widnows 10 ha una linux machine intermedia
  • #7: Prima gli sviluppatori inviavano I war + I file di configurazione ai sistemisti e spesso c’erano problemi nel deploy per via di qualche dettaglio sfuggito. Ora si può inviare il war del Progetto con il dockerfile che contiene al suo interno tutte le configurazioni e non ci sono quindi più errori
  • #9: Ogni virtual machine ha il suo Sistema Operativo e quindi un alto consumo di risorse. Gigabyte vs megabyte Velocità di caricamento Docker però ha meno isolamento (il kernel è condiviso) mentre le virtual machine sono completamente isolate e possono girare facilmente su più sistemi operativi In grossi sistemi si usa una soluzione ibrida con più container in una macchina virtuale per sfruttuare i vantaggi di entrambe le soluzioni
  • #11: Le immagini sono template da cui creare più container.
