go-cron | simple Cron library for go that can execute closures | Cron Utils library

I am working on a web app in Django and I need to send some random numbers to the database every day at 8am.

I have tried to use celery but it has not worked. I am using windows and from a tutorial I understand celery does not work on windows.

I have tried using django-extensions and django-cron but it needs changes made to the linux cron and as I said before, I am on windows.

How should I solve this? Any help would be appreciated.

When running pip install django-cron I get the following error:

I am getting this error when building my docker-compose.yml. I have a django project and when I try to install its dependencies I get the following error:

I'm sharing my GitHub repository link for your reference. https://github.com/deepenpatel19/test_django_cron

Here, I have set up one project to test cron scheduler in Docker. but, the scheduler is not being run on time. I have to run manually.

Django dependencies:

Having a working gitlab instance on an Ubuntu 18.04 server for abouth 2 months, it now refuse to swpan due to the following 2 errors in /var/log/nginx/error.log

I am using Docker to deploy Python2.7 application with Django1.8. I am facing some issue from last two days and I found error as below.

Docker Image: python:2.7-slim-buster

Error:

I am sorry if its basics but I did not find any answers on the Internet comparing these two technologies. How should I decide when to use which as both can be used to schedule and process periodic tasks.

This is what an article says:

Django-celery :

Jobs are essential part of any application that does some processing for you in the background. If your job is real time Django application celery can be used.

Django-cronjobs :

django-cronjobs can be used to schedule periodic_task which is a valid job. django-cronjobs is a simple Django app that runs registered cron jobs via a management command.

can anyone explain me the difference between when should I choose which one and Why? Also I need to know why celery is used when the computing is distributed and why not cron jobs

I am currently working with HDFS, Apache Livy and Django, the goal of this is to send a request to get some code running which is stored in HDFS and which calls Livy to create Batches. For now, everything is working, I have a basic wordcount stored in HDFS, with a .txt file, and on a htlm page I just have a simple button to click on to launch the whole process.

I succeed in creating the wordcount result, and my next step is to get informations from Livy, for instance the ID of the sessions (or batches) currently starting/running/dead/success some sort of callback, but I need the it to self actualize so I can know what states are every sessions in. To do so, I thought I could use Django-cron, therefore I can't manage to set it correctly. I have no errors but nothing more is happening. What am I missing ?

Currently working on Centos7 but I'm using a Conda environment in Python 3.6, with Django latest release, so are livy and HDFS (latest release)

Here are my current files :

I have few cronjobs running with the help of django-crontab. Let us take one cronjob as an example, suppose this job A is scheduled to run every two minutes.

However, while the job is running and if it is not finished in two minutes, I do not want another instance of this job to execute.

Exploring few resources, I came across this article, but I am not sure where to fit this in.
