20:14 <superherointj> I am trying to use K3s in NixOS but I am having a hard time. It fails `k3s check-config` with 3 errors: "k3s check-config | grep fail /n- CONFIG_CGROUP_FREEZER: missing (fail) /n- CONFIG_NF_NAT_IPV4: missing (fail) /n- CONFIG_NF_NAT_NEEDED: missing (fail) /n STATUS: 3 (fail)"

20:15 <superherointj> I wonder what I am missing to fix: "CONFIG_CGROUP_FREEZER"

20:16 <q3k|m> all of these look like unset kernel options, right

20:17 <q3k|m> if you're willing to rebuild your kernel, you can do that: https://nixos.wiki/wiki/Linux_kernel#Custom_configuration

20:28 <superherointj> Thanks for answering. I'm not really sure if it is kernel options.

20:28 <superherointj> (I just don't know.)

20:28 <q3k|m> well these definitely are kernel options

20:30 <superherointj> Right.

20:31 <q3k|m> just not sure if rebuilding the kernel to flip 'em is what you necessarily want to do here

20:31 <q3k|m> vs, dunno, ignoring it complaining about these (maybe they're not strictly necessary) or somewhat reconfiguring k3s to not require them

20:32 <superherointj> I am considering not using k3s anymore and go for usual kubernetes.

20:32 <superherointj> *going

20:32 <superherointj> I am using RockPro64 as hardware. A bit limited. 4GB ram.

20:32 <q3k|m> i mean, unless you're well versed in deploying k8s, then flipping these options will be significantly less effort than switching to full k8s

20:33 <q3k|m> flip the flags then IMO. the build is gonna take a while on that box, but i still think it's less effort than running k8s

20:33 <q3k|m> also good point, i should also try k3s on my rockpro

20:33 <superherointj> I am in uncharted territory both ways.

20:33 <superherointj> Oh cool.

20:33 <q3k|m> my spidey tenses tell me the kernel option flip way is slightly more likely to succeed faster

20:34 <q3k|m> but i won't insist

20:34 <q3k|m> s,tenses,senses,

20:34 <superherointj> Allright. Thanks. I'll give it a try. (or at least attempt)

20:35 <q3k|m> do report back, I'm genuinely curious about how this goes

20:35 <superherointj> Sure.

22:26 <q3k|m> superherointj: i'm also now compiling linux on my pine64 for unrelated reasons :P

23:03 <superherointj> cool. I've got a lot to learn.
