Ansible Role: Swap

This Ansible Role sets up swap space on Linux systems.

Requirements

None.

Role Variables

Here are the variables you can use, along with their default values (check defaults/main.yml for more details):

• swap_file_path: /swapfile
  This is where the swap file will be located on the server.

• swap_file_size_mb: '512'
  This is the size of the swap file in mebibytes.

• swap_swappiness: '60'
  This sets the vm.swappiness value in the system configuration.

• swap_file_state: present
  Set this to absent if you want to remove the swap file and disable swap. Usually, you would set it to present.

• swap_file_create_command: "dd if=/dev/zero of={{ swap_file_path }} bs=1M count={{ swap_file_size_mb }}"
  This is the command for creating the swap file. You can use fallocate for faster creation, but it may result in inconsistencies compared to dd.

Dependencies

None.
