Can we use OR operator in Helm yaml files
Can I do something like this in Helm yamls :
{{- if eq .Values.isCar true }} OR {{- if eq .Values.isBus true }}
# do something
{{- end }}
I understand that we can do a single if check. But how would I check for multiple conditions? Are there some operators equivalent to OR and AND?
Answer
As indicated in the Helm documentation on operators:
For templates, the operators (
eq,ne,lt,gt,and,orand so on) are all implemented as functions. In pipelines, operations can be grouped with parentheses ((, and)).
It means you could use
{{- if or (eq .Values.isCar true) (eq .Values.isBus true) }}
Furthermore, as noted in the if/else structure:
A pipeline is evaluated as false if the value is:
- a boolean false
- a numeric zero
- an empty string
- a nil (empty or null)
- an empty collection (map, slice, tuple, dict, array)
Under all other conditions, the condition is true.
If your properties (isCar and isBus) are booleans, you can then skip the equal check:
{{- if or .Values.isCar .Values.isBus }}
