Containers require configuration data
Configuration files are often generated on the fly…
…and added during container start
apiVersion: v1
kind: ConfigMap
metadata:
name: foo
data:
file1.ext: |
data1
file2.ext: |
data2
ConfigsMaps store one or more values…
…which can be literals as well as files
Multi-line values are possible
Values can be provided to pods as environment variables
