Service
Expose an application running on a set of Pods as a network service.
Kubernetes gives Pods their own IP addresses and a single DNS name for a
set of Pods, and can load-balance across them.
▪ ConfigMaps
API object used to store non-confidential data in key-value pairs. Pods can
consume ConfigMaps as environment variables, command-line arguments, or
as configuration files in a volume.
▪ Secrets
Store and manage sensitive information, such as passwords, OAuth tokens,
and ssh keys.
▪ Volumes
Persistent storage location that can be mounted into a pod. Volumes can be
used to store data that needs to persist across container restarts or be shared
between multiple containers in a pod.
