Kule ting

• Røska opp i "it's always been that way"
   
• Helt sinnssykt lett å starte opp apper lokalt
   
• dev/prod parity: egen Java-versjon uten puppetroot!
   
• Lett å definere replicas, rolling updates
   
• Service discovery er mye enklere!

Gotchas

• Les ARTIFACT_NAME fra env, ikke properties
   
• Monorepo? Putt filene i modulen
   

• $ kubectl exec -it <pod name> bash
