It seems resources can't be created with label value set to 'true' or 'false'.
With the following yaml,
template:
metadata:
labels:
environment: test
release: false
tier: frontend
I'm getting error:
$ kubectl create -f replicaset.yaml
unable to decode "replicaset.yaml": [pos 341]: json: expect char '"' but got char 'f'
but change to
template:
metadata:
labels:
environment: test
release: stable
tier: frontend
No error:
$ kubectl create -f replicaset.yaml
replicaset "replicaset" created
Label documentation doesn't mention this case.
Valid label values must be 63 characters or less and must be empty or begin and end with an alphanumeric character ([a-z0-9A-Z]) with dashes (-), underscores (_), dots (.), and alphanumerics between.
The use case for using 'true' as label value is to use "Exist", "NotExist" selector, where you don't have a meaningful label value.
I haven't tested yet, but if yaml parser convert it to typed boolean value before we even get the value, then it might not be easy to fix? If so and we don't want to support it, then I'd think we at least document it somehow.
