Cron jobs allow you to run scheduled tasks at specified times or intervals. To set up a cron job, add a configuration similar to the following:
.upsun/config.yaml
applications:
  myapp:
    crons:
      snapshot:
        spec: 0 5 * * *
        commands:
          start: |
            croncape symfony ...
To run a command in a cron hook for specific environment types, use the PLATFORM_ENVIRONMENT_TYPE environment variable:
.upsun/config.yaml
applications:
  myapp:
    crons:
      snapshot:
        spec: 0 5 * * *
        commands:
          start: |
            # only run for the production environment, aka main branch
            if [ "$PLATFORM_ENVIRONMENT_TYPE" = "production" ]; then
              croncape symfony ...
            fi

​
Use croncape

When using the Symfony integration, you can use croncape to get feedback through emails when something goes wrong. To specify which email address croncape must send the feedback emails to, add a MAILTO environment variable. To do so, run the following command: 
symfony var:create -y --level=project --name=env:MAILTO --value=sysadmin@example.com
To ensure better reliability, croncape sends the emails using:
  • project-id@cron.noreply.platformsh.site as the sender address (project-id+branch@cron.noreply.platformsh.site for non-main environments)
  • the provided UpsunSMTP service, even if you define your own MAILER_* environment variables
To use a custom SMTP and/or custom sender address, follow these steps:
  1. To specify a sender address, define a MAILFROM environment variable.
  2. Define the mandatory environment variables to use your own email service. Note that only SMTP connections are supported.
  3. To disable the provided SMTP service, run symfony upsun:env:info enable_smtp false.
To use croncape, SMTP must be enabled on the environment, where the PLATFORM_SMTP_HOST environment variable is accessible. This variable is available, and SMTP enabled, by default on all production environments.This is not the case for preview (non-production) environments, where it must be enabled with the command symfony cloud:env:info enable_smtp true.
