I'm having a PHP file which has some JS in it. I run a script on this file which will check if the date on a firebase database matches with the current date and if not update a few values. So I want this PHP file to run 24x7. I am completely new to heroku. Is it possible to do this on heroku or is there any other simpler solution ? Any help would be appreciated.
I don't see why not. You can set a worker process in your Procfile that will run a non web based process. In that PHP script you can set a timer to perform this action daily, and if were to crash for whatever reason, Heroku would restart the process.
Here's an explanation of how they work: https://devcenter.heroku.com/articles/background-jobs-queueing

im using crontab on a server to run a shell script which uses pgloader to load data into a postgresql everyday and i have bitbucket pipeline with a python script that runs every week, but i want the bitbucket pipeline only to run if the cronjob was successfull.
I thought of 2 possible ways to solve the problem:
Using hc-ping to get the status of the cronjob, but im not sure i understood the documentation of hc-ping correctly, as i understood it you can only check if crontab functions properly and not the status of the jobs itself?
Another method i thought of was to check wether the data migration with pgloader was successful or not and create a file depending on it which is used in another cronjob and get the hc-ping of that cronjob. If the file was not created then the job would fail and i could check with hc-ping that the crontab was not run.
I appreciate every help i can get.
Best regards
I send mail as a cron job with Laravel. For this, when I want to use the last value I added in my resources/lang/de.json file in the mail blade template file(resources/views/mails/...blade.php), it gives an output as if such a value is not defined. However, if I use the same key in a blade file I created before, it works without any errors. In addition, the keys that I added to the same file (de.json) in the first time work without errors in the same mail blade file.
Thinking it's some kind of cache situation, I researched and found out that restarting the queue worker might fix the problem. However, both locally and on the server with ssh.
'php artisan queue:restart'
Even though I ran the command, there was no improvement.
Do you have any ideas?
Since queue workers are long-lived processes, they will not notice changes to your code without being restarted. So, the simplest way to deploy an application using queue workers is to restart the workers during your deployment process. https://laravel.com/docs/9.x/queues#queue-workers-and-deployment
but php artisan queue:restart will instruct all queue workers to gracefully exit after they finish processing their current job so that no existing jobs are lost. And I see a lot of issues with this command not to solve restart and deploy the worker.
So, Simplest way,
try to stop the worker manually (ctrl+C)
start the worker again with php artisan queue:work again.
might this help.
I'm really struggling with this issue, which is a little frustrating to me because it seems to be so simple in a Linux server. I have a Windows Azure Web App and I want to run "php artisan queue:listen" on the server continuously to take care of dispatched jobs. From what I read from the documentation, in Linux you just use Supervisor to run the command constantly and to revive it, in case it dies. From what I found online, Azure has a similar functionality called WebJobs where you can serve them a script to be ran and then decide whether it should run on a schedule or continuously (kinda like the Scheduler in Laravel). With this I have 2 questions.
1 - Is this the right solution? Place a script to run the command on a WebJob and have the WebJob run continuously?
2 - I'm not experienced in writing php scripts to run command lines, so all I can do is something like this:
echo shell_exec('php artisan queue:work');
Problem is this does not give me the output of the command (I don't see anything like the "processed" result that I see when I run the command by hand on my command console and a job is processed). It is important to me to be able to read the output of the command, because I want to be able to check the logs for errors in case something happens when a job isn't able to be processed. From the documentation shell_exec returns null in case an error is thrown so I'm completely clueless on how to deal with this.
Thank you so much in advance!
Instead of using shell_exec() you can directly upload .cmd file which includes your command php artisan queue:work, and then you can find the output log in WebJob Details page.
About how to do that, please check Ernesto's answer out.
For Azure you can make a new webjob to your web app, and upload a .cmd
file including a command like this.
php %HOME%\site\wwwroot\artisan queue:work --daemon
and defining that as a triguered and 0 * * * * * frecuency cron.
that way work for me.
For more information, please refer to Run Background tasks with WebJobs.
Using Codeigniter 2.2.0 for my project. Is $this->input->is_cli_request() validation is necessary for a cron job?
It is recommended to protect your cronjob not to execute when someone type the URL in their browser. However if you don't have any problem running your cronjob invoked by anyone then can avoid this check.
Refer https://ellislab.com/codeigniter/user-guide/general/cli.html for more details.
It recommented to run cron jobs with command line.
There are many reasons for running CodeIgniter from the command-line, but they are not always obvious.
Run your cron-jobs without needing to use wget or curl
Make your cron-jobs inaccessible from being loaded in the URL by checking for $this->input->is_cli_request()
Make interactive "tasks" that can do things like set permissions, prune cache folders, run backups, etc.
Integrate with other applications in other languages. For example, a random C++ script could call one command and run code in your models!

But you also can prevent calling from URL in your server.
I've uploaded a single file to Heroku that crawls a website and responds the edited content in JSON format on an http request. I now want to update the content regularly so the content stays up to date. I tried using the Heroku Scheduler however I am failing to schedule the process so that it runs correctly.
I have specified the following process in the Heroku Scheduler:
run phantomjs phantom.js //Using 1X Dyno, every hour.
//phantom.js is the file that contains my source code and that runs the server.
However if I enter
heroku ps
into the terminal, I only see one web dyne running and no scheduler task. Also if I type
heroku logs --ps scheduler.1
as described in the Scheduler documentation, there is no output.
What am I doing wrong? Any help would be appreciated.
For what it sounds like you want to accomplish, you need to be constantly running
1 Web Dyno
1 Background Worker
When your scheduled task executes, it will be run by the background worker. Which, since you haven't provisioned it, isn't executing.
Found it: I only had to write
phantomjs phantom.js
in order to get it working. It was the "run" that made the expression invalid
