```shell
k3s-agent -t <token> -s https://<master>:6443
```
(Here `<token>` is found in `/var/lib/rancher/k3s/server/node-token` at the
k3s master.)

k3s-agent -t /var/lib/rancher/k3s/server/node-token -s https://localhost:6443
```
If you are running an all in one node (both the server and agent) for testing
purposes, do not run the above script. It will perform cleanup and break flannel
networking on your host.
Instead, run the following (note the space between 'k3s' and 'agent'):
```shell
k3s agent -t /var/lib/rancher/k3s/server/token --server http://localhost:6443/
```
## Notes:
if running under qemu, the default of 256M of memory is not enough, k3s will
OOM and exit.
Memory:
Boot with qemuparams="-m 2048" to boot with 2G of memory (or choose the
appropriate amount for your configuration)

Disk: if using qemu and core-image* you'll need to add extra space in your disks
to ensure containers can start. The following in your image recipe, or local.conf
would add 2G of extra space to the rootfs:
