title: "Digital Rebar"
description: "In this guide we will create an Kubernetes cluster with 1 worker node, and 2 controlplane nodes using an existing digital rebar deployment."
---

## Prerequisites

- 3 nodes (please see [hardware requirements](/v0.9/en/guides/getting-started#system-requirements))
- Loadbalancer
- Digital Rebar Server
- Talosctl access (see [talosctl setup](/v0.9/en/guides/getting-started/talosctl))

## Creating a Cluster

In this guide we will create an Kubernetes cluster with 1 worker node, and 2 controlplane nodes.
We assume an existing digital rebar deployment, and some familiarity with iPXE.

We leave it up to the user to decide if they would like to use static networking, or DHCP.
The setup and configuration of DHCP will not be covered.

### Create the Machine Configuration Files

#### Generating Base Configurations

Using the DNS name of the load balancer, generate the base configuration files for the Talos machines:

```bash
$ talosctl gen config talos-k8s-metal-tutorial https://<load balancer IP or DNS>:<port>
created init.yaml
created controlplane.yaml
created join.yaml
created talosconfig
```

> The loadbalancer is used to distribute the load across multiple controlplane nodes.
> This isn't covered in detail, because we asume some loadbalancing knowledge before hand.
> If you think this should be added to the docs, please [create a issue](https://github.com/talos-systems/talos/issues).
At this point, you can modify the generated configs to your liking.

#### Validate the Configuration Files

```bash
$ talosctl validate --config init.yaml --mode metal
init.yaml is valid for metal mode
$ talosctl validate --config controlplane.yaml --mode metal
controlplane.yaml is valid for metal mode
$ talosctl validate --config join.yaml --mode metal
join.yaml is valid for metal mode
```

#### Publishing the Machine Configuration Files

Digital Rebar has a build-in fileserver, which means we can use this feature to expose the talos configuration files.
We will place `init.yaml`, `controlplane.yaml`, and `worker.yaml` into Digital Rebar file server by using the `drpcli` tools.

Copy the generated files from the step above into your Digital Rebar installation.

```bash
drpcli file upload <file>.yaml as <file>.yaml
```

Replacing `<file>` with init, controlplane or worker.

### Download the boot files

Download a recent version of `boot.tar.gz` from [github.](https://github.com/talos-systems/talos/releases/)

Upload to DRB:

```bash
$ drpcli isos upload boot.tar.gz as talos.tar.gz
{
"Path": "talos.tar.gz",
"Size": 96470072
}
```

We have some Digital Rebar [example files](https://github.com/talos-systems/talos/tree/master/hack/test/digitalrebar/) in the Git repo you can use to provision Digital Rebar with drpcli.

To apply these configs you need to create them, and then apply them as follow:

```bash
$ drpcli bootenvs create talos
{
"Available": true,
"BootParams": "",
"Bundle": "",
"Description": "",
"Documentation": "",
"Endpoint": "",
"Errors": [],
"Initrds": [],
"Kernel": "",
"Meta": {},
"Name": "talos",
"OS": {
"Codename": "",
"Family": "",
"IsoFile": "",
"IsoSha256": "",
"IsoUrl": "",
"Name": "",
"SupportedArchitectures": {},
"Version": ""
},
"OnlyUnknown": false,
"OptionalParams": [],
"ReadOnly": false,
"RequiredParams": [],
"Templates": [],
"Validated": true
}
```

```bash
drpcli bootenvs update talos - < bootenv.yaml
```

> You need to do this for all files in the example directory.
> If you don't have access to the `drpcli` tools you can also use the webinterface.
It's important to have a corresponding SHA256 hash matching the boot.tar.gz

#### Bootenv BootParams

We're using some of Digital Rebar build in templating to make sure the machine gets the correct role assigned.

`talos.platform=metal talos.config={{ .ProvisionerURL }}/files/{{.Param \"talos/role\"}}.yaml"`

This is why we also include a `params.yaml` in the example directory to make sure the role is set to one of the following:

- controlplane
- init
- worker

The `{{.Param \"talos/role\"}}` then gets populated with one of the above roles.

### Boot the Machines

In the UI of Digital Rebar you need to select the machines you want te provision.
Once selected, you need to assign to following:

- Profile
- Workflow

This will provision the Stage and Bootenv with the talos values.
Once this is done, you can boot the machine.

To understand the boot process, we have a higher level overview located at [metal overview.](/v0.9/en/guides/metal/overview)

### Retrieve the `kubeconfig`

Once everything is running we can retrieve the admin `kubeconfig` by running:

```bash
talosctl --talosconfig talosconfig config endpoint <control plane 1 IP>
talosctl --talosconfig talosconfig config node <control plane 1 IP>
talosctl --talosconfig talosconfig kubeconfig .
```

title: "Equinix Metal"
description: "Creating Talos cluster using Enquinix Metal."
---

## Prerequisites

This guide assumes the user has a working API token, the Equinix Metal CLI installed, and some familiarity with the CLI.

## Network Booting

To install Talos to a server a working TFTP and iPXE server are needed.
How this is done varies and is left as an exercise for the user.
In general this requires a Talos kernel vmlinuz and initramfs.
These assets can be downloaded from a given [release](https://github.com/talos-systems/talos/releases).

## Special Considerations

### PXE Boot Kernel Parameters

The following is a list of kernel parameters required by Talos:

- `talos.platform`: set this to `packet`
- `init_on_alloc=1`: required by KSPP
- `init_on_free=1`: required by KSPP
- `slab_nomerge`: required by KSPP
- `pti=on`: required by KSPP

### User Data

To configure a Talos you can use the metadata service provide by Equinix Metal.
It is required to add a shebang to the top of the configuration file.
The shebang is arbitrary in the case of Talos, and the convention we use is `#!talos`.

## Creating a Cluster via the Equinix Metal CLI

### Control Plane Endpoint

The strategy used for an HA cluster varies and is left as an exercise for the user.
Some of the known ways are:

- DNS
- Load Balancer
- BPG

### Create the Machine Configuration Files

#### Generating Base Configurations

Using the DNS name of the loadbalancer created earlier, generate the base configuration files for the Talos machines:

```bash
$ talosctl gen config talos-k8s-aws-tutorial https://<load balancer IP or DNS>:<port>
created init.yaml
created controlplane.yaml
created join.yaml
created talosconfig
```

Now add the required shebang (e.g. `#!talos`) at the top of `init.yaml`, `controlplane.yaml`, and `join.yaml`
At this point, you can modify the generated configs to your liking.

#### Validate the Configuration Files

```bash
talosctl validate --config init.yaml --mode metal
talosctl validate --config controlplane.yaml --mode metal
talosctl validate --config join.yaml --mode metal
```

> Note: Validation of the install disk could potentially fail as the validation
> is performed on you local machine and the specified disk may not exist.
#### Create the Bootstrap Node

```bash
packet device create \
--project-id $PROJECT_ID \
--facility $FACILITY \
--ipxe-script-url $PXE_SERVER \
--operating-system "custom_ipxe" \
--plan $PLAN\
--hostname $HOSTNAME\
--userdata-file init.yaml
```

#### Create the Remaining Control Plane Nodes

```bash
packet device create \
--project-id $PROJECT_ID \
--facility $FACILITY \
--ipxe-script-url $PXE_SERVER \
--operating-system "custom_ipxe" \
--plan $PLAN\
--hostname $HOSTNAME\
--userdata-file controlplane.yaml
```

> Note: The above should be invoked at least twice in order for `etcd` to form quorum.
#### Create the Worker Nodes

```bash
packet device create \
--project-id $PROJECT_ID \
--facility $FACILITY \
--ipxe-script-url $PXE_SERVER \
--operating-system "custom_ipxe" \
--plan $PLAN\
--hostname $HOSTNAME\
--userdata-file join.yaml
```

### Retrieve the `kubeconfig`

At this point we can retrieve the admin `kubeconfig` by running:

```bash
talosctl --talosconfig talosconfig config endpoint <control plane 1 IP>
talosctl --talosconfig talosconfig config node <control plane 1 IP>
talosctl --talosconfig talosconfig kubeconfig .
```
