Microservice Documentation

The microservice reads from programs_to_run.txt and executes each command listed. An example command that can be given to the microservice is as follows

py thingThatNeedsExecuting.py

To formally call this microservice from another python application, it is recommended to approach as follows.

import subprocess

# Create the programs_to_run.txt file
programs = [
    "py applicationToRun.py",
]

with open('programs_to_run.txt', 'w') as file:
    for program in programs:
        file.write(f"{program}\n")

# Run the microservice
subprocess.run(['python', 'microService.py'])

Once running, the microservice will execute each command listed in the programs_to_run.txt file.

Data from the microservice can be observed in the form of commands being removed from the programs_to_run.txt. Succesful operations are noted in the terminal by the microservice. The user is responsible for handling Data proccessed by commands executed by the microservice. An example of using the programs_to_run.txt to evaluate data might be as follows.

while True:
    time.sleep(1)

    with open('programs_to_run.txt', 'r') as file:
        lines = file.readlines()

    if not lines:
        print("The MicroService is Done!")
        break

In this example, once the microservice has been called we wait on the .txt file to be fully empty before continuing with our application.
