AWS Elastic Beanstalk: Running Cron.d script, missing Environment Variables

Question

I\'m trying to run a PHP script that is triggered by a cron script (in cron.d). The script is triggered properly but it is missing the Elastic Beanstalk \"Environment Variab

Answer 1

I spent several hours trying to figure out how to pass Environment Variables to PHP CLI. I tried:

• setting in ebextensions config: $ source /opt/elasticbeanstalk/support/envvars.d/sysenv
• setting all my Environment variables to config file.

No matter what I tried, env variables won't pass to PHP CLI.

When I log to my EC2 instance as ec2-user and do this: $ echo $ENVIRONMENT I get prod. If I do it as $ sudo su and then $ echo $ENVIRONMENT I get prod.

If I manually run the PHP CLI file (used in cronjob) my script works. When it runs automatically (via cronjob) Environment Variables are not passed to my script.

Here's what I did. Put this in your cronjob entry script:

$variables = '/opt/elasticbeanstalk/support/envvars.d/sysenv';

if (file_exists($variables) && is_file($variables)) {
    $contents = file_get_contents($variables);
    foreach(explode("\n", $contents) as $line) {
        if (empty($line)) continue;

        $new_line = str_replace('export ', '', $line);
        $first_part = strpos($new_line, '=');

        $last_part = substr($new_line, $first_part, strlen($new_line));
        $variable_value = str_replace(array('=', '"'), array('',''), $last_part);

        $variable_name = substr($new_line, 0, $first_part);
        putenv($variable_name."=".$variable_value);
    }
}

It extracts each line from /opt/elasticbeanstalk/support/envvars.d/sysenv file, removes the export part, gets the variable name & value, and sets it via putenv() function.
