Let's start by adding the main part of our application - the dependency container (further just the container). In this section, we will configure logging and reading the configuration file. The next step is to set up logging and reading the configuration file.
Asyncio file monitor code#
The container starts and exits with code 0. Monitoring-daemon-tutorial_monitor_1 exited with code 0 doneĪttaching to monitoring-daemon-tutorial_monitor_1 Successfully tagged monitoring-daemon:latestĪfter the build process is complete, start the container:Ĭreating network "monitoring-daemon-tutorial_default" with the default driverĬreating monitoring-daemon-tutorial_monitor_1. The build process can take several minutes. Let's start building the image and check that the environment is configured correctly. Let's add the following lines to the file docker-compose.yml :Įverything is ready.
The last step is to define the settings docker-compose. Let's add the following lines to the file Dockerfile :ĬMD We will use it python:3.8-buster as a base image. It will describe the process of building and starting our daemon. Let's add the following lines to the file requirements.txt :
dependency-injector - dependency injection framework.In this section, we will prepare the environment for starting our daemon.įirst you need to define dependencies. Next, we are waiting for the preparation of the environment. We will expand it in the following sections. Create files and folders following the structure below. Now we need to create an initial project structure. Let's move on to the structure of the project. If Docker or docker-compose are not installed, they need to be installed before proceeding. The output should look something like this:ĭocker version 19.03.12, build 48a66213feĭocker-compose version 1.26.2, build eefe0d31
We will be using Docker and docker-compose. When receiving a response, it will write the following data to the log: The daemon will send requests to and every few seconds. We will be building a monitoring daemon that will monitor access to web services. Understanding the principle of dependency injection.The completed project can be found on Github.
Asyncio file monitor manual#
The manual consists of the following parts: Today I want to show how you can build an asynchronous daemon based on a module asyncio. This is another tutorial for building applications with the Dependency Injector. This is a dependency injection framework for Python.
