Terraform template for setting up a virtual warewulf test cluster. It pull an
OS appliance and install warewulf on it. You can login to the nodes as
root with the password linux.
[!WARNING]
This is only for testing purpose as weak passwords are set and ssh keys are
handled not securely. Also the warewulf rpm package is installed without
gpg check.
Terraform must be installed, the user must be part of the libvirt group and
terraform init has to run.
Simply run
terraform apply
what will create the instance ww4-host (172.16.?.250) and per default 4 nodes
called n[01-04] on the the 172.16.?.0 virtual network, where '?' is a
random number, what allows to have several workspaces at the same time. The
keys of the file ~/.ssh/authorized_keys are exported to the root account on
ww4-host. The root account has the password linux. Also the according
warewulf package is installed, but not further configured. The default base OS
is a openSUSE Leap 15.5, but following other base OS for ww4-host can be
selected by setting the command line variable distribution:
- leap (openSUSE Leap 15.5)
- tw (openSUSE Tumbleweed)
- local-zypp (use local.qcow2 and zypper for installation)
Now you can login to the ww4-host and check if warewulf.conf got the right
network configuration. After that configure warewulf with following command
systemctl enable --now warewulfd
wwctl configure -a
and add the nodes with
wwctl node add n[01-04] -I 172.16.?.101
From this point on you should check the warewulf documentation on how to set up the cluster.
After the test you have to remove the virtual machines with
terraform destroy
terraform apply -var="nr_nodes=2"
terraform apply -var="packages=fortune"
The key in ~/.ssh/authorized_keys are copied over to ww4-host. If there is
more than one key, cloud-init fails.
