springcloud python 注册到 eureca/gateway

tornado注册
import tornado.httpserver
import tornado.ioloop
import tornado.options
import tornado.web
import py_eureka_client.eureka_client as eureka_client
from tornado.options import define, options
define("port", default=3333, help="run on the given port", type=int)
class IndexHandler(tornado.web.RequestHandler):
def get(self):
username = self.get_argument("username", "Hello")
self.write(username + ", Administrator User!")
def post(self):
username = self.get_argument("username", "Hello")
self.write(username + ", Administrator User!")

class MainHandler(tornado.web.RequestHandler):

username = self.get_argument("username", "Hello")
self.write(username + ", Coisini User!")
def post(self):

def main():

app = tornado.web.Application(handlers=[(r"/test", IndexHandler), (r"/main", MainHandler)])
http_server = tornado.httpserver.HTTPServer(app)
http_server.listen(options.port)
client.start()
tornado.ioloop.IOLoop.instance().start()
if name == "main":
main()
django注册
注册时注册上电脑名识别不出来，需要注册上ip,只要将instance_host改为ip即可
client = eureka_client.EurekaClient(eureka_server="http://admin:adminEureka@127.0.0.1:8761/eureka/",
# instance_id=options.ip+':'+str(options.port),
# home_page_url=options.ip+':'+str(options.port),
instance_host=options.ip,
instance_ip=options.ip, app_name="sb-business-statistics",
instance_port=options.port)
client.start()
动态获取ip
def get_host_ip():
try:
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.connect(('8.8.8.8', 80))
ip = s.getsockname()[0]
finally:
s.close()
return ip
将项目发布到k8s docker

调整熔断器闭合断开状态
hystrix.command.default.metrics.rollingStats.timeInMilliseconds=50000

前提条件，一定时间内发起一定数量的请求。 也就是5秒钟内(这个5秒对应下面的滚动窗口长度)至少请求1次，熔断器才发挥起作用。 默认20

hystrix.command.default.circuitBreaker.requestVolumeThreshold=1

错误百分比。达到或超过这个百分比，熔断器打开。 比如：5秒内有4个请求，2个请求超时或者失败，就会自动开启熔断

hystrix.command.default.circuitBreaker.errorThresholdPercentage=50 是指50%失败超时达到一半时打开熔断
