Running a cluster locally¶
You can spawn a local MetalK8s cluster by running
This command will start a virtual machine (using VirtualBox) and:
mount the build tree
import a private SSH key (automatically generated in
generate a boostrap configuration
execute the bootstrap script to make this machine a bootstrap node
provision sparse-file Volumes for Prometheus and Alertmanager to run on this bootstrap node
After executing this command, you have a MetalK8s bootstrap node up and running
and you can connect to it by using
vagrant ssh bootstrap.
Note that you can extend your cluster by spawning extra nodes (up to 9 are
already pre-defined in the provided
Vagrantfile) by running
vagrant up node1 --provision.
spawn a virtual machine for the node 1
import the pre-shared SSH key into it
You can then follow the cluster expansion procedure to add the freshly spawned
node into your MetalK8s cluster (you can get the node’s IP with
vagrant ssh node1 -- sudo ip a show eth1).
