7. Container Image
   Dependencies
   Application Code
   Containers encapsulate application code and all
   dependencies.
   Applications can be depend less on the infrastructure
   where it runs.
   • In traditional IT environments, applications needed specific
   infrastructure. Dependencies needed to be installed beforehand.
   • Containers incorporate applications and their dependencies so
   deployment to development, test, and production can be made
   easier.
   • Don’t need to be dependent on on-premise, private or public
   cloud environments.
   What are Containers?

   just a few milliseconds.
   Portable
   Can be run in a many
   environments.
   Efficiency
   Low overhead. Resources
   use by containers can be
   limited.

    Services
    A group of pods that work together
    • grouped by a selector
    Defines access policy
    • “load balanced” or “headless”
    Gets a stable virtual IP and port
    • sometimes called the service portal
    • also a DNS name
    VIP is managed by kube-proxy
    • watches all services
    • updates iptables when backends change
    Hides complexity - ideal for non-native apps
