In order to DRY up all installation methods and mount methods, this PR introduces a few more runtime modes. The modes are then used to determine the strategy for creating and or mounting the paritions. Signed-off-by: Andrew Rynhard <andrew@andrewrynhard.com>

## Creating a Master Node
|
|
|
|
On `Dom0`, install Talos to an available block device:
|
|
|
|
```bash
|
|
docker run \
|
|
--rm \
|
|
--privileged \
|
|
--volume /dev:/dev \
|
|
talos-systems/talos:latest image -b /dev/sdb
|
|
```
|
|
|
|
Save the following as `/etc/xen/master.cfg`
|
|
|
|
```python
|
|
name = "master"
|
|
|
|
builder='hvm'
|
|
bootloader = "/bin/pygrub"
|
|
firmware_override = "/usr/lib64/xen/boot/hvmloader"
|
|
|
|
vcpus=2
|
|
memory = 4096
|
|
serial = "pty"
|
|
|
|
kernel = "/var/lib/xen/talos/vmlinuz"
|
|
ramdisk = "/var/lib/xen/talos/initramfs.xz"
|
|
disk = [ 'phy:/dev/sdb,xvda,w', ]
|
|
vif = [ 'mac=52:54:00:A8:4C:E1,bridge=xenbr0,model=e1000', ]
|
|
extra = "consoleblank=0 console=hvc0 console=tty0 console=ttyS0,9600 talos.platform=metal talos.userdata=http://${IP}:8080/master.yaml"
|
|
```
|
|
|
|
{{% note %}}`http://${IP}:8080/master.yaml` should be reachable by the VM and contain a valid master configuration file.{{% /note %}}
|
|
|
|
Now, create the VM:
|
|
|
|
```bash
|
|
xl create /etc/xen/master.cfg
|
|
```
|
|
|
|
## Creating a Worker Node
|
|
|
|
On `Dom0`, install Talos to an available block device:
|
|
|
|
```bash
|
|
docker run \
|
|
--rm \
|
|
--privileged \
|
|
--volume /dev:/dev \
|
|
talos-systems/talos:latest image -b /dev/sdc
|
|
```
|
|
|
|
Save the following as `/etc/xen/worker.cfg`
|
|
|
|
```python
|
|
name = "worker"
|
|
|
|
builder='hvm'
|
|
bootloader = "/bin/pygrub"
|
|
firmware_override = "/usr/lib64/xen/boot/hvmloader"
|
|
|
|
vcpus=2
|
|
memory = 4096
|
|
serial = "pty"
|
|
|
|
kernel = "/var/lib/xen/talos/vmlinuz"
|
|
ramdisk = "/var/lib/xen/talos/initramfs.xz"
|
|
disk = [ 'phy:/dev/sdc,xvda,w', ]
|
|
vif = [ 'mac=52:54:00:B9:5D:F2,bridge=xenbr0,model=e1000', ]
|
|
extra = "consoleblank=0 console=hvc0 console=tty0 console=ttyS0,9600 talos.platform=metal talos.userdata=http://${IP}:8080/worker.yaml"
|
|
```
|
|
|
|
{{% note %}}`http://${IP}:8080/worker.yaml` should be reachable by the VM and contain a valid worker configuration file.{{% /note %}}
|
|
|
|
Now, create the VM:
