Question
access service from worker instance

Asked by Juliver Galleto
I successfully created a worker using this https://docs.digitalocean.com/developer-center/how-to-setup-a-job-scheduler-on-digitalocean-app-platform/, while this is very easy and uses curl as an example, my problem is I need to run php script from the service instance so I need the crontab to access the service outside the worker container to run a php script e.g. /workspace/.heroku/php/bin/php /workspace/bin/console mautic:segments:update. I know I can access the internal service via exposed port 8080 by http://<name>:<port> but due to security concern, I would like to directly access the service rather than using http.
appspec is similar to this

Hi there,
I recently had a discussion about this here:
The documentation that you’ve shared gives a Node.js sample app as an example to trigger HTTP endpoints. In order for this to work, you need to get the files from the
docker-cronrepo and use the Dockerfile from the example repo as a blueprint and adjust it for your PHP project.That way, rather than running the example
curlcommand from the demo Node app, the Worker component will clone your PHP project and will have access to all of the necessary files.There is a PHP Dockerfile example in the answer above.
The alternative option as you mentioned is to use the internal port and send HTTP requests instead.
Hope that this helps!
Best,
Bobby
