     1  {{- /*
     2  name defines a template for the name of the chart. It should be used for the `app` label. 
     3  This is common practice in many Kubernetes manifests, and is not Helm-specific.
     4  
     5  The prevailing wisdom is that names should only contain a-z, 0-9 plus dot (.) and dash (-), and should
     6  not exceed 63 characters.
     7  
     8  Parameters:
     9  
    10  - .Values.nameOverride: Replaces the computed name with this given name
    11  - .Values.namePrefix: Prefix
    12  - .Values.global.namePrefix: Global prefix
    13  - .Values.nameSuffix: Suffix
    14  - .Values.global.nameSuffix: Global suffix
    15  
    16  The applied order is: "global prefix + prefix + name + suffix + global suffix"
