Output not compatible with the GKE integration

[ricmalta]

I'm doing a basic integration with negroni and logrus middleware using this formatter . However the format is not being recognised by stackdriver. My Implementation:

utils.logger.go

package utils

import (
	"os"

	stackdriver "github.com/TV4/logrus-stackdriver-formatter"
	"github.com/sirupsen/logrus"
)

// NewLogger instance
func NewLogger(name string) (*logrus.Logger, error) {
	logger := logrus.New()
	logger.Out = os.Stdout
	logger.Formatter = stackdriver.NewFormatter(
		stackdriver.WithService(name),
		stackdriver.WithVersion("v0.1.0"),
	)

	return logger, nil
}

Middleware implementation

// NewMainMiddleware creates a middleware with common app middlewares
func NewMainMiddleware(middleware *negroni.Negroni, apiConfig config.APIConfig) *negroni.Negroni {
	log, _ := utils.NewLogger("http")

	return middleware.
		With(negroni.NewRecovery()).
		With(negronilogrus.NewMiddlewareFromLogger(log, "http")).
		With(LanguageMiddleware{}).
		With(timeoutMiddleware(apiConfig))
}

As you can see the playload is in the jsonPayload.context.data and not being actually filtered by stackdriver. By your code, the fields are not completely compatible with the current (v2) LogEntry definition: https://cloud.google.com/logging/docs/reference/v2/rest/v2/LogEntry.

There is any easy solution to this or this module is deprecated?
