Cannot set valid loadBalancerSourceRanges on K8s cluster

[Setsushin]

Name and Version

bitnami/spark

What architecture are you using?

amd64

What steps will reproduce the bug?

1. Set following configs in values.yaml (dummy example)

# In values.yaml
service:
  type: LoadBalancer
  annotations:
    cloud.google.com/load-balancer-type: External
  allocateLoadBalancerNodePorts: true
  loadBalancerSourceRanges:
  - 1.1.1.1/32
  - 2.2.2.2/32

2. Run helm upgrade --install spark bitnami/spark -f values.yaml
3. Got the error

Are you using any custom parameters or values?

service:
  type: LoadBalancer
  annotations:
    cloud.google.com/load-balancer-type: External
  allocateLoadBalancerNodePorts: true
  loadBalancerSourceRanges:
  - 1.1.1.1/32
  - 2.2.2.2/32

What is the expected behavior?

An external LoadBalancer service with corresponding IP source range should be created.

What do you see instead?

❯ helm upgrade --install spark bitnami/spark -f values.yaml
Error: UPGRADE FAILED: cannot patch "spark-master-svc" with kind Service: Service "spark-master-svc" is invalid: spec.LoadBalancerSourceRanges: Invalid value: "[1.1.1.1/32 2.2.2.2/32]": must be a list of IP ranges. For example, 10.240.0.0/24,10.250.0.0/24 

Additional information

I tried to use

loadBalancerSourceRanges: "[1.1.1.1/32, 2.2.2.2/32]"

as instead and it passed.

As the error says, you need to use a list of IP ranges in the following way: 10.240.0.0/24,10.250.0.0/24

@carrodher Thanks for the reply! I converted it to a STRING then it passed the verification.

loadBalancerSourceRanges:
  - 10.240.0.0/24
  - 10.250.0.0/24

Btw, I have used the above method in many other Helm repos, and it is also considered correct. I wonder if there are any plans to improve usability in this regard?
