我的问题非常简单，它与名为 KinD 的 kubernetes 很棒的工具有关。我正在为我的烧瓶应用程序使用 KindD：
import os
import requests
from flask import Flask
from jaeger_client import Config
from flask_opentracing import FlaskTracing
app = Flask(__name__)
config = Config(
config={
'sampler':
{'type': 'const',
'param': 1},
'logging': True,
'reporter_batch_size': 1,},
service_name="service")
jaeger_tracer = config.initialize_tracer()
tracing = FlaskTracing(jaeger_tracer, True, app)
def get_counter(counter_endpoint):
counter_response = requests.get(counter_endpoint)
return counter_response.text
def increase_counter(counter_endpoint):
counter_response = requests.post(counter_endpoint)
return counter_response.text
@app.route('/')
def hello_world():
counter_service = os.environ.get('COUNTER_ENDPOINT', default="https://localhost:5000")
counter_endpoint = f'{counter_service}/api/counter'
counter = get_counter(counter_endpoint)
increase_counter(counter_endpoint)
return f"""Hello, World!
You're visitor number {counter} in here!\n\n"""
FROM python:3.7-alpine
RUN mkdir /app
RUN apk add --no-cache py3-pip python3 && \
pip3 install flask Flask-Opentracing jaeger-client
WORKDIR /app
ADD ./app /app/
ADD ./requirements.txt /app/
RUN pip install -r requirements.txt
EXPOSE 5000
CMD ["python", "/app/main.py"]

结果：
一切看起来都很好。当我编写浏览器时：http: //172.42.42.101 :6000/
结果：
另外，我想添加我的服务事件。一切看起来都不错：
并且我还想添加@Kaan Mersin 建议：我添加了 80 作为默认端口。
