anything I am missing ?
c
sudo doesn’t pass through environment variables. don’t do that.
take the sudo out and just run sh
the script itself will sudo as necessary

f
let me try, will share the update
this is what I am seeing now -

k3s@atul-miniserver-k3s:~$ curl -sfL <https://get.k3s.io> | INSTALL_K3S_VERSION="1.27.7" INSTALL_K3S_EXEC="server --tls-san X.X.X.X --disable=traefik" sh -

c
1.27.7
is not a valid K3s version
did you mean 
v1.27.7+k3s1
?
✅ 1
f
no, 
1.27.7
works but with 
sudo
, seems like script is misbehaving -

it looks like its doing what it’s supposed to. what’s the problem?
[INFO] No change detected so skipping service start
you’ve reinstalled the same version with the same config so it’s not restarting the service
f
INSTALL_K3S_EXEC
script does not honour the above env when used with 
sudo
, tried with 
sudo sh -E -
as well, no luck If i do not pass this variable, k3s is installed successfully but again with 
sudo
without 
sudo
it do not do anything.
c
what makes you think its not using it
f
I have checked the cert for SAN IP ( it does not allow the IP, I am setting via --tls-san option)
c
Do you see the --tls-san arg in 
/etc/systemd/system/k3s.service
? If so, then the install script is working.
f
No, It did not -

may be this is GCP machine which is causing this shenanigans, It does not respect

without

just do that. nothing else
why not
what happens if you run that exactly as I posted

sh -s
option worked, I think, we should update the github read me - https://github.com/k3s-io/k3s#quick-start---install-script
I will raise the PR
c
either should work, -s isn’t generally necessary but I do it out of habit. is 
sh
on this box busybox or something?
f
I am using 
GCP machine
which has 
debian-12 boot image
c
what exactly happens if you don’t add -s
f
as I mentioned, somehow it did not honour the 
INSTALL_K3S_EXEC
env variable
c
But it is somehow honoring the version variable? that doesn’t make any sense to me
