Why we need it
Current env field is a simple map (map[string]string), but user may want to config env by dowardAPI
How to do
change api same as pod.spec.containers.env
FIELDS:
name <string> -required-
Name of the environment variable. Must be a C_IDENTIFIER.
value <string>
Variable references $(VAR_NAME) are expanded using the previously defined
environment variables in the container and any service environment
variables. If a variable cannot be resolved, the reference in the input
string will be unchanged. Double $$ are reduced to a single $, which allows
for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will produce the
string literal "$(VAR_NAME)". Escaped references will never be expanded,
regardless of whether the variable exists or not. Defaults to "".
valueFrom <EnvVarSource>
Source for the environment variable's value. Cannot be used if value is not
empty.
