To start with Edge, review the [architecture](architecture.md) and the [lifecycle](edge-native-lifecycle.md) resource to gain a high-level understanding of the Edge components and installation process. Next, become familiar with the [EdgeForge workflow](edgeforge-workflow/edgeforge-workflow.md). EdgeForge is the workflow you will use to customize the Edge host installation to match your environment and organizational needs - this includes creating the Edge artifacts for Edge hosts. The last step of the Edge deployment lifecycle is the deployment step. Review the [Deployment](site-deployment/site-deployment.md) guide to understand what it takes to deploy an Edge host.

You can also review [third party integrations](third-party-integrations/third-party-integrations.md) with Edge to solve specific challenges with additional software.

You can use Tailscale on your Palette Edge hosts to ensure remote access to your Edge hosts that are connected to the internet. Tailscale provides point-to-point, full-mesh VPN networking with high levels of performance and security. With Tailscale installed, you can use always SSH to access your Edge hosts that have internet access, even if your Edge hosts experience problems with Kubernetes.

## Limitations

- Tailscale magicDNS is not compatible with network overlay in Edge clusters. If your Edge cluster has [network overlay](../networking/vxlan-overlay.md) enabled, you must disable MagicDNS in Tailscale or ensure you don't use the 100.100.100.100 DNS server that MagicDNS configures.

## Prerequisites

- A Tailscale account. Visit [Tailscale official website](https://login.tailscale.com/start) to register a Tailscale account.

- A Tailscale authorization key. We recommend you use a reusable, non-ephemeral key that automatically tags the devices with one or more tags. For more information about auth keys, refer to [Tailscale documentation](https://tailscale.com/kb/1085/auth-keys).

- A host machine with an AMD64 processor architecture. You will use this host machine to build Edge artifacts using CanvOS.

- At least one Edge device with an AMD64 processor architecture registered with your Palette account.

- Your Edge devices must be able to connect to Tailscale. This usually means the Edge device must have an internet connection.

- An external volume that can be flashed with the Edge installer ISO. For example, a USB drive.

- This how-to uses the EdgeForge workflow to build artifacts used to provision Edge hosts. Review [EdgeForge Workflow](../edgeforge-workflow/palette-canvos.md) to become familiar with how to build EdgeForge artifacts.

## Use Tailscale to Remotely Connect to Your Edge Cluster

1. Check out the [CanvOS](https://github.com/spectrocloud/CanvOS) GitHub repository. Change to the **CanvOS** directory and choose a version tag.

2. Add the following content to the end of the file `Dockerfile` to include the Tailscale package in the Edge OS build:

<Tabs>
<TabItem value="ubuntu" label="Ubuntu">

```dockerfile
RUN curl -fsSL "https://pkgs.tailscale.com/stable/ubuntu/kinetic.noarmor.gpg" | sudo tee /usr/share/keyrings/tailscale-archive-keyring.gpg >/dev/null && \
curl -fsSL "https://pkgs.tailscale.com/stable/ubuntu/kinetic.tailscale-keyring.list" | sudo tee /etc/apt/sources.list.d/tailscale.list && \
apt update -y && \
apt install -y tailscale && \
apt-get clean && rm -rf /var/lib/apt/lists/*
```

</TabItem>

<TabItem value="redhat" label="RedHat">

```dockerfile
RUN dnf config-manager --add-repo https://pkgs.tailscale.com/stable/rhel/9/tailscale.repo && \
dnf install tailscale && \
dnf clean all
```

</TabItem>

<TabItem value="other" label="Other">

If you use a different OS, adjust the commands in accordance with the Tailscale [documentation](https://tailscale.com/kb/1031/install-linux/).

</TabItem>
</Tabs>

If you already have commands in your `Dockerfile` that install packages, you can either merge these together with the above content, or keep them as separate RUN statements. Note that every RUN statement creates its own image layer and fewer layers are generally better.

3. Review the **.arg.template** file containing the customizable arguments and create an **.arg** file. Below is a command you can use to create an example **.arg** file. For more information, refer to the [Build Edge Artifacts](../edgeforge-workflow/palette-canvos.md) guide.

```bash
cat << EOF > .arg
CUSTOM_TAG=$CUSTOM_TAG
IMAGE_REGISTRY=ttl.sh
OS_DISTRIBUTION=ubuntu
IMAGE_REPO=ubuntu
OS_VERSION=22
K8S_DISTRIBUTION=k3s
ISO_NAME=palette-edge-installer
ARCH=amd64
HTTPS_PROXY=
HTTP_PROXY=
PROXY_CERT_PATH=
UPDATE_KERNEL=false
EOF
```

4. Issue the command below to save your tenant registration token to an environment variable. Replace `[your_token_here]` with your actual registration token.

```bash
export token=[your_token_here]
```

5. Issue the following command to create the **user-data** file. Note that we're adding a bind mount for `/var/lib/tailscale` to ensure the state of Tailscale is persisted across node reboots.
```yaml
cat << EOF > user-data
stylus:
site:
paletteEndpoint: api.spectrocloud.com
edgeHostToken: $token
projectName: Default
name: edge-randomid
install:
poweroff: true
bind_mounts:
- /var/lib/tailscale
users:
- name: kairos
passwd: kairos
EOF
```
6. Next, add a `stages` block to the **user-data** file to automatically enable Tailscale and register the Edge device. Replace `$AUTH-KEY` with your authorization key from Tailscale:
```yaml {14}
stages:
boot.after:
- name: "Register device with Tailscale"
if: '[ ! -f "/run/cos/recovery_mode" ] && ! grep _current-profile /var/lib/tailscale/tailscaled.state'
commands:
- |
ID=$(cat /sys/class/dmi/id/product_uuid)
if [ -f /oem/tailscale/tailscaled.state ]; then
systemctl stop tailscaled
cp /oem/tailscale/tailscaled.state /var/lib/tailscale/tailscaled.state
systemctl start tailscaled
tailscale up --ssh --hostname="edge-${ID}"
else
tailscale up --authkey=$AUTH-KEY --ssh --hostname="edge-${ID}"
mkdir /oem/tailscale
cp /var/lib/tailscale/tailscaled.state /oem/tailscale/tailscaled.state
fi
- name: "Enable Tailscale"
if: '[ ! -f "/run/cos/recovery_mode" ] && grep _current-profile /var/lib/tailscale/tailscaled.state'
commands:
- |
ID=$(cat /sys/class/dmi/id/product_uuid)
tailscale up --ssh --hostname="edge-${ID}"
```
If you already have a `stages` block in your user-data file, you must merge the existing block together with the above content. The `stages` block is based on Kairos cloud-init stages. For more information on cloud init stages, refer to [Cloud Init Stages](../edge-configuration/cloud-init.md).
:::info
In the above `stages` block, you are using the device ID of your Edge device that is read from the file **/sys/class/dmi/id/product_uuid**, as the hostname with which to register your device with Tailscale. For more information about how this ID is generated, refer to [Install Configurations](../edge-configuration/installer-reference.md#device-id-uid-parameters).
If you want to use a different hostname, especially when using the `deviceUIDPaths` parameter in the **user-data**, you can adjust the two `ID=$(cat /sys/class/dmi/id/product_uuid)` lines in the content above to match your custom device naming configuration.
:::
7. Build the Edge device installation ISO and providers images.
```shell
sudo ./earthly.sh +build-all-images
```
This command may take up to 15-20 minutes to finish depending on the resources of the host machine. Upon completion, the command will display the manifest that you must use in your cluster profile to deploy your cluster.
```shell
===================== Earthly Build SUCCESS =====================
Share your logs with an Earthly account (experimental)! Register for one at https://ci.earthly.dev.
```
8. Afterward, push the provider images to an image registry. For more information, refer to [Build Edge Artifacts](../edgeforge-workflow/palette-canvos.md).
8. Flash your external volume with the Edge installer ISO image. You can use [balena etcher](https://etcher.balena.io/) or any other tool of your choice to flash your volume.
9. Plug the external volume into your Edge device and boot up the device using the volume to prepare your Edge device for installation. For more information, refer to [Prepare Edge Host for Installation](../site-deployment/stage.md).
10. Remove the volume and boot up your device again to register your Edge host. If the Edge host has internet access, it will start up Tailscale and register your device with Tailscale.
## Validate
1. Log in to [Tailscale console](https://login.tailscale.com/admin/machines).
2. In the **Machines** tab, your Edge device is displayed in the Machines list. You can SSH to your host from any device that is also connected to your Tailscale network. Check out the [Tailscale SSH](https://tailscale.com/kb/1193/tailscale-ssh) documentation page to learn more about SSH with Tailscale.
## Troubleshooting
### All Traffic Dropped for 100.64.0.0/10 CIDR Range
Tailscale uses the 100.64.0.0/10 range of IP addresses for your Tailnets. That means that by default, this address range, or parts of it, cannot be used for any of the following:
- Kubernetes cluster pod CIDR
- Kubernetes cluster service CIDR
- Palette Edge Overlay network CIDR
#### Debug Steps
If you want to use parts of the 100.64.0.0/10 range for your Kubernetes clusters or your Palette Edge Overlay networks, you must limit the IP address range that your Tailnet uses to a fraction of the 100.64.0.0/10 range. Use the following steps to limit your Tailnet range:
1. First, configure an IP Pool in Tailscale. We have found the following configuration works well to assign addresses in the new range to all nodes:
```json
"nodeAttrs": [
{
"target": ["*"],
"ipPool": ["100.74.0.0/16"],
},
],
```
2. Next, in the OS pack of your cluster profile, add the following:
```yaml
stages:
initramfs:
- name: "Tailscale fix systemD unit service"
files:
- path: /etc/systemd/system/tailscale-iptables-fix.service
permissions: 0644
owner: 0
group: 0
content: |
[Unit]
Description=Tailscale iptables fix service
[Service]
ExecStart=/etc/palette/tailscale-iptables.sh
[Install]
WantedBy=multi-user.target
- name: "Tailscale fix systemD unit timer"
files:
- path: /etc/systemd/system/tailscale-iptables-fix.timer
permissions: 0644
owner: 0
group: 0
content: |
[Unit]
Description=Tailscale iptables fix schedule
[Timer]
OnBootSec=15
OnUnitActiveSec=15
[Install]
WantedBy=timers.target
- name: "Tailscale adjustment script"
files:
- path: /etc/palette/tailscale-iptables.sh
permissions: 0755
owner: 0
group: 0
content: |
#!/bin/sh
if iptables -L ts-input | grep DROP | grep 100.64.0.0/10; then
RULEFWD=$(iptables -L ts-forward --line-numbers | grep DROP | grep 100.64.0.0/10 | awk '{print $1}')
RULEINP=$(iptables -L ts-input --line-numbers | grep DROP | grep 100.64.0.0/10 | awk '{print $1}')
iptables -R ts-forward $RULEFWD -s 100.74.0.0/16 -o tailscale0 -j DROP
iptables -R ts-input $RULEINP -s 100.74.0.0/16 -o tailscale0 -j DROP
fi
network:
- name: "Reduce scope of traffic dropped by Tailscale to just the Tailscale ipPool"
commands:
- |
systemctl enable tailscale-iptables-fix.service
systemctl enable tailscale-iptables-fix.timer
systemctl start tailscale-iptables-fix.timer
```
This will ensure Tailscale does not drop traffic for IP ranges that it doesn't own. This is due to a known bug in Tailscale. Even though we restricted the IP Pool, Tailscale still puts in `iptables` rule on every node that drops unknown traffic from any address in the entire 100.64.0.0/10 range.
