[help] cannot create node on Alpine linux 3.17

cannot create node on Alpine linux 3.17

It can create cluster on debian or ubuntu, but alpine.

Expected behavior
alpine has no sudo, and apk can not found sudo.

Environments

• OS: alpine linux[v3.17]
• AutoK3s Version [v0.7.0]

Refer to https://www.suse.com/suse-k3s/support-matrix/all-supported-versions/k3s-v1-26/

It is a k3s support matrix problem. Although from k3s docs says that K3s is expected to work on most modern Linux systems., it also has the support matrix and the alpine isn't in that list. So the autok3s is also not expected to install k3s in alpine linux.

We will look into the possibility to install k3s in alpine but I don't think it is a bug of autok3s.

I tried to use curl -sfL https://get.k3s.io | sh - and succeed to install k3s in alpine 3.17.2. We will improve the install script in autok3s.

I visited https://docs.rancher.cn/docs/k3s/advanced/_index, it has how to setup k3s on alpine linux, I thought it‘s about create cluster on alpine by autok3s.
maybe should modify the doc?

Thank orangedeng

This issue is the autok3s problem. The install script from autok3s is using sudo which the alpine doesn't have. Both the support matrix and community docs are fine.

The support matrix is more about the commercial support. It doesn't affect that K3s is expected to work on most modern Linux systems.

I will fix it in v0.9.0

Resolved in v0.9.0-rc1, already tested autok3s install k3s on Alpine linux with 1 master and 1 worker node via airgap install.
