Just ran the following command to create a new ConfigMap from a file:kubernetes create configmap foo --from-file=foo
It gets created successfully.
Now when I run,kubernetes get configmaps foo -o yaml
I see the following lines in the resulting output:
apiVersion: v1
data:
foo: |+
VAR1=value1
VAR2=value2What does the plus sign in this line mean?foo: |+
It doesn't appear in any of my other ConfigMaps.
|+ is not kubernetes specific, it's part of yaml.
From http://lzone.de/cheat-sheet/YAML:
# + indicator (keep extra newlines after block)
content: |+
Arbitrary free text with two newlines after
foo: ...
