Variable references $(VAR_NAME) are expanded
using the previous defined environment variables in the container and
any route environment variables. If a variable cannot be resolved,
the reference in the input string will be unchanged. The $(VAR_NAME)
syntax can be escaped with a double $$, ie: $$(VAR_NAME). Escaped
references will never be expanded, regardless of whether the variable
exists or not.
Defaults to "", and the maximum length is 32768 bytes.
