Add feature: Disable swap
geerlingguy opened this issue · comments
I was thinking about adding some functionality to disable swap on my Kubernetes role... then realized I have this role, and it would be a perfect little feature addition.
Basically, for Kubernetes (and for other purposes sometimes), it's a good idea to disable swap entirely. Therefore, this role could be set into a mode to just disable swap permanently, using a bool variable like swap_disable.
Hmm, I already have swap_file_state, but I can go further.
Or maybe not. Testing this out with an example from the geerlingguy/ansible-for-devops repo, as well as geerlingguy/raspberry-pi-dramble...
Yeah... so we can disable swap—in this example on Debian 9 in VirtualBox—like so:
swap_file_state: absent
swap_file_path: /dev/mapper/packer--debian--9--amd64--vg-swap_1
Simple!
