Disable swap #266

Closed dberardo-com closed 1 year ago

dberardo-com commented 1 year ago

I assume that swap needs to be disabled during installation:

Don't mess with this in k3s-ansible.

I have a preflight.yml and do whatever it requires in there. e.g. swap, enable/disable ipv6, install nfs-common, LANG to C.UTF-8, install ntp and htpdate (for fixing the clock after a VM restore), install qemu-guest-agent,

So you see there is plenty to do - totaly legit - but it is 1000% out of the scope of k3s-ansible.

is the preflight optional in the procedure? i wonder why the swap hasnt been disabled in my case, maybe that was skipped ? can that be run on a already existing cluster?

Preflight is my own file I created.... (preflight.yml).
