Splitting/exploding a string from vault in consul template

[dcam...@sofi.org]

I have a vault store that looks like the following:

/secret/users/someuser

key = "groups"

value = "group1,group2,group3" (comma separated values string)

I would like a way to explode that string into an array, and run the consul template {{range}} on the array to loop through each of them. I know I could solve for this by having keys group1 group2 group3 etc, but I would like the key to be dynamic enough to handle any number of values.

Is this possible?
