Not working inside docker image

[prakashpandey]

Logger library is working as expected in Linux (Ubuntu 18.04 LTS) and in Mac os but
when I am running it in docker having alpine Linux as a base image, it is stuck at

logger.Init("foo", *verbose, true, lf)

I am using its latest version by downloading it using go get github.com/google/logger

It's blocking the entire application as the func logger.Init() is not returning.

My implementation:

func mustInitLogger() *logger.Logger {
	fmt.Printf("initializing x-microservice application log\n")
	lf, err  := os.OpenFile(logPath, os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0644)
	if err != nil {
		panic(err)
	}
	fmt.Printf("log file created, initializing x-microservice logger instance\n")
	logr := logger.Init("x-microservice", true, true, lf)
	logger.SetFlags(log.LstdFlags)
	fmt.Printf("log initialization done\n")
	return logr
}

Update:

When I switched to version v1.0.1, I get this error:

unix syslog delivery error

[molchalin]

you can disable write in syslog
logger.Init("foo", *verbose, false, lf)

[SeanBurford]

The current code deadlocks if it needs to output an Error log in Init, since Init takes the logging mutex.

[SeanBurford]

In our case we want syslog set to True, and if that fails falling back to the default logger would be a good choice.

This should be fixed by #37
