Back to our app: worker.py

Let's follow our app from code to deployment in a container.

During each step we'll analyze the software and show some highlights.

Step 1: The code

import logging
import os
from redis import Redis
import requests
import time
...
redis = Redis("redis")
...
def work_loop(interval=1):
    deadline = 0
    loops_done = 0
    while True:
        if time.time() > deadline:
            log.info("{} units of work done, updating hash counter"
                     .format(loops_done))
            redis.incrby("hashes", loops_done)
            loops_done = 0
            deadline = time.time() + interval
        work_once()
        loops_done += 1

if __name__ == "__main__":
    while True:
        try:
            work_loop()
        except:
            log.exception("In work loop:")
            log.error("Waiting 10s and restarting.")
            time.sleep(10)
