To be able to replace substring in terraform we have the replace() function, but this function can only be applied to a string, not a list of strings. How do we replace, for example, the http for https in the following list of strings?
input = [ "http://systemadmin.es", "http://pet2cattle.com" ]
Even though HCL is a declarative language, we can use for to apply the replace() function to each item un out list:
output = [ for item in var.input: replace(item, "http://", "https://") ]
The contents of the output variable are going to be:
output = [ "https://systemadmin.es", "https://pet2cattle.com" ]
