Bash 4.2 Associative arrays throws "bad array subscript" error

Question

I'm trying to create this associative array, but it throws an error because of the volumeClaimTemplates[0]

This is my code:

declare -A example=(["'spec.statefulSet.spec.volumeClaimTemplates[0].spec'"]="TEST")

This is the error:

['spec.statefulSet.spec.volumeClaimTemplates[0].spec']=TEST: bad array subscript

If I remove the [0] from the volumeClaimTemplates then I get no errors.

Answer 1

Got it to work like this

declare -A example=(["spec.statefulSet.spec.volumeClaimTemplates[0\].spec.storageClassName"]="TEST"
