Terraform - FotD - matchkeys()
Read OriginalThis technical blog post details the Terraform built-in interpolation function matchkeys(). It covers the function's purpose, syntax (matchkeys(values, keys, search_set)), and includes code examples demonstrating how to use it to filter a list of values based on matching keys from a search set. The article contrasts it with the lookup() function and discusses practical applications, such as querying maps for multiple values.
