log is a simple logrus helper to allow attaching a logrus.Entry to a context.Context.

// Create a ctx that carries a logrus.Entry with field "cmd" indicating the executable being run
ctx := log.WithField(ctx, "cmd", os.Args[0])
ctx = log.WithFields(ctx,WithFields(parent, 
            logrus.Fields{
                "pid": os.Getpid(),
                "uid": os.Getuid(),
            },
       )
// Log with the Entry from the ctx
log.Entry(ctx).Info("Informational log")
