# Controlling `headscale` with remote CLI
|
|
|
|
## Prerequisit
|
|
|
|
- A workstation to run `headscale` (could be Linux, macOS, other supported platforms)
|
|
- A `headscale` server (version `0.13.0` or newer)
|
|
- Access to create API keys (local access to the `headscale` server)
|
|
- `headscale` _must_ be served over TLS/HTTPS
|
|
- Remote access does _not_ support unencrypted traffic.
|
|
|
|
## Goal
|
|
|
|
This documentation has the goal of showing a user how-to set control a `headscale` instance
|
|
from a remote machine with the `headscale` command line binary.
|
|
|
|
## Create an API key
|
|
|
|
We need to create an API key to authenticate our remote `headscale` when using it from our workstation.
|
|
|
|
To create a API key, log into your `headscale` server and generate a key:
|
|
|
|
```shell
|
|
headscale apikeys create --expiration 90d
|
|
```
|
|
|
|
Copy the output of the command and save it for later. Please not that you can not retrieve a key again,
|
|
if the key is lost, expire the old one, and create a new key.
|
|
|
|
To list the keys currently assosicated with the server:
|
|
|
|
```shell
|
|
headscale apikeys list
|
|
```
|
|
|
|
and to expire a key:
|
|
|
|
```shell
|
|
headscale apikeys expire --prefix "<PREFIX>"
|
|
```
|
|
|
|
## Download and configure `headscale`
|
|
|
|
1. Download the latest [`headscale` binary from GitHub's release page](https://github.com/juanfont/headscale/releases):
|
|
|
|
2. Put the binary somewhere in your `PATH`, e.g. `/usr/local/bin/headcale`
|
|
|
|
3. Make `headscale` executable:
|
|
|
|
```shell
|
|
chmod +x /usr/local/bin/headscale
|
|
```
|
|
|
|
4. Configure the CLI through Environment Variables
|
|
|
|
```shell
|
|
export HEADSCALE_CLI_ADDRESS="<HEADSCALE ADDRESS>"
|
|
export HEADSCALE_CLI_API_KEY="<API KEY FROM PREVIOUS STAGE>"
|
|
```
|
|
|
|
This will tell the `headscale` binary to connect to a remote instance, instead of looking
|
|
for a local instance (which is what it does on the server).
|
|
|
|
The API key is needed to make sure that your are allowed to access the server. The key is _not_
|
|
needed when running directly on the server, as the connection is local.
|
|
|
|
5. Test the connection
|
|
|
|
Let us run the headscale command to verify that we can connect by listing our nodes:
|
|
|
|
```shell
|
|
headscale nodes list
|
|
```
|
|
|
|
You should now be able to see a list of your nodes from your workstation, and you can
|
|
now control the `headscale` server from your workstation.
|
|
|
|
## Troubleshooting
|
|
|
|
Checklist:
|
|
|
|
- Make sure you have the _same_ `headscale` version on your server and workstation
|
|
- Make sure you use version `0.13.0` or newer.
|
|
- Verify that your TLS certificate is valid
|
|
- If it is not valid, set the environment variable `HEADSCALE_CLI_INSECURE=true` to allow insecure certs.
