Configuration files

Here’s a quick run-through the conf files available in this AMIs.

  • autorun.sh - This script will be executed at every boot, using the admin user. Keep in mind that the AMI will make read-only the file on every boot, and it will chown it to admin. You’ll find this script useful if you want to execute some extra tasks after booting, such as collecting static files or maybe running migrations.

  • cron/* - This folder contains the usual /etc/cron.* folders structure you’d expect to have. Scripts inside these folders (d, daily, hourly, monthly, weekly) will be copied to the corresponding folder in /etc/cron.*. Note that file names should be LANANA-assigned namespace, aka run-parts(8) compliant, aka only upper- and lower-case letters, digits, underscores and hyphens. They also must end with a new empty line.

  • global/hostname - Sets the hostname. Use any of the available variables:

    • KERNEL_NAME

    • NODENAME

    • KERNEL_RELEASE

    • KERNEL_VERSION

    • MACHINE

    • PROCESSOR

    • HARDWARE_PLATFORM

    • OS

    • IP_ADDR

      Keep in mind that the value of the resulting string will be slugified according to **RFC 1123**, which means that only letters, digits and hyphens are allowed.

  • global/timezone - Sets the timezone. Use whatever you’d normally put in your /etc/timezone file. Check /usr/share/zoneinfo/.

  • mail/msmtprc - You can configure an SMTP server which will be used to send alerts from Auditd, RKHunter, Fail2ban, etc…​

  • mail/notifications - Write a single line containing a valid email address to which the alerts should be sent.
