Flask Eureka Integration

flask-eureka's Issues

Failing to get port in Windows

While trying to register flask service, Eureka client tries to get ipv4 with this code:
def ipv4(self): if self.system == 'Darwin': ipv4 = getoutput("ifconfig " + self.iface + " | grep 'inet ' | awk '{ print $2 }'") else: ipv4 = getoutput("ifconfig " + self.iface + " | grep 'inet addr' | awk '{ print $2 }'") ipv4 = ipv4.split(':')[1]
Here command ifconfig is called in terminal. However, there's no such command in Windows terminal, so getoutput function result is '"ifconfig" ­Ґ пў«пҐвбп ў­гв७­Ґ© Ё«Ё ў­Ґи­Ґ© Є®¬ ­¤®©, ЁбЇ®«­пҐ¬®© Їа®Ја ¬¬®© Ё«Ё Ї ЄҐв­л¬ д ©«®¬.'. By decoding this, I get '"ifconfig" не является внутренней или внешней командой, исполняемой программой или пакетным файлом.', which is the message that command was not found in Russian. Unsuprisingly, the whole library won't work on Windows.

Please do a release

Configuration won't load

Hi,

I got a running Spring Netflix Eureka Server and tried to connect a flask client to it.
When I try to start the Flask Server I get the following error message and I can't find out where the error is.

Der Befehl ""ifconfig en0 | grep 'inet addr' | awk '{ print $2 }'"" ist entweder falsch geschrieben oder
konnte nicht gefunden werden.
Traceback (most recent call last):
  File "C:/Projects/PDA/web-crawler-service/webcrawlerservice/WebCrawlerService.py", line 62, in <module>
    connect_to_eureka()

    raise CalledProcessError(retcode, cmd, output=output)
subprocess.CalledProcessError: Command '["ifconfig en0 | grep 'inet addr' | awk '{ print $2 }'"]' returned non-zero exit status 1

Attached you can find my configuration file and the python script which I am running.

My Spring Eureka Server has the following configuration:

spring:
  application:
    name: eureka-service
server:
  port: 8761
eureka:
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://localhost:8761/

Thanks

你这个项目只支持Linux环境运行？

在hostInfo.py文件里面没有找到关于windows系统的命令提取

latest release do not have the port related changes in flask_eureka/eurekaclient.py
