<p>I'm trying to run k3s in rootless-mode. For now, i've done common steps from <a href="https://rootlesscontaine.rs/getting-started" rel="nofollow noreferrer">https://rootlesscontaine.rs/getting-started</a> and used unit-file from <a href="https://github.com/k3s-io/k3s/blob/master/k3s-rootless.service" rel="nofollow noreferrer">https://github.com/k3s-io/k3s/blob/master/k3s-rootless.service</a></p>
<p>Systemd service k3s-rootless.service is active and run, but the pods are constantly in pending status.</p>
<p>I get these messages:</p>

<p>What should i do next?</p>

Dmitry
<p>The solution was quite obvious.
In unit file k3s-rootless.service I used the wrong snapshotter. For containerd in k3s rootless-mode it has to be '--snapshotter=fuse-overlayfs'.
fuse-overlayf also need to be installed before run k3s in rootless-mode.</p>
