Configuration for logging

type Logger

type Logger struct {
	*zerolog.Logger
}

func Configure

func Configure(config Config) *Logger

Configure sets up the logging framework

In production, the container logs will be collected and file logging should be disabled. However, during development it's nicer to see logs as text and optionally write to a file when debugging problems in the containerized pipeline

The output log file will be located at /var/log/service-xyz/service-xyz.log and will be rolled according to configuration set.
