Role Variables

Available variables are listed below, along with default values (see defaults/main.yml):

How large (in mebibytes) to make the swap file.

swap_swappiness: '60'

The vm.swappiness value to be configured in sysconfig.

swap_file_state: present

If you wish to remove your swapfile, and disable swap, set this to absent. Generally you'd probably want to set this to present.

swap_file_create_command: "dd if=/dev/zero of={{ swap_file_path }} bs=1M count={{ swap_file_size_mb }}"

The command used to create the swap file. You could switch to using fallocate to write the swap file more quickly, though there may be inconsistencies if not writing the file with dd.
