Config defines the format of a configuration file in either JSON or HCL format.

It must contain only pointer values, slices and maps to support standardized merging of multiple Config structs into one.

Since this is the format which users use to specify their configuration it should be treated as an external API which cannot be changed and refactored at will since this will break existing setups.

func Merge 

func Merge(files ...Config) Config

Merge recursively combines a set of config file structures into a single structure according to the following rules:

* only values of type struct, slice, map and pointer to simple types are allowed. Other types panic. * when merging two structs the result is the recursive merge of all fields according to the rules below * when merging two slices the result is the second slice appended to the first * when merging two maps the result is the second map overlaid on the first * when merging two pointer values the result is the second value if it is not nil, otherwise the first

Upstream represents a single upstream dependency for a service or proxy. It describes the mechanism used to discover instances to communicate with (the Target) as well as any potential client configuration that may be useful such as load balancer options, timeouts etc.
