A Cockpit application to manage Tailscale

Development
|
|
-----------
|
|
|
|
This repo story includes deployment scripts for the Cocpit Tailscale development environment.
|
|
The easiest to get started is by using the following cloud development environments:
|
|
|
|
* Open in [Gitpod workspace](https://gitpod.io/#https://github.com/spotsnel/cockpit-tailscale)
|
|
* Open in [CodeSandbox](https://codesandbox.io/p/github/spotsnel/cockpit-tailscale)
|
|
|
|
or you can either use a local `devsys`/`almsys`, as published here:
|
|
|
|
* https://github.com/gbraad-devenv/fedora

|
|
|
|
|
|
|
|
### Preparation
|
|
|
|
Install the following packages to develop and build:
|
|
|
|
```bash
|
|
$ sudo dnf install -y make npm
|
|
```
|
|
|
|
and to make the RPM you need:
|
|
|
|
```bash
|
|
$ sudo dnf install -y rpm-build gettext libappstream-glib
|
|
```
|
|
|
|
|
|
#### Cockpit user
|
|
|
|
If you want to run Cockpit, you need a user with a password:
|
|
|
|
```bash
|
|
$ sudo dnf install -y passwd
|
|
$ sudo passwd gbraad
|
|
```
|
|
|
|
After which you can use this user to log in to Cockpit.
|
|
|
|
|
|
### Build
|
|
|
|
To perform a development build:
|
|
```bash
|
|
$ npm run dev
|
|
````
|
|
|
|
To perform a production build:
|
|
```bash
|
|
$ npm run build
|
|
```
|
|
|
|
For the RPM package:
|
|
```bash
|
|
$ npm run rpm
|
|
```
|
|
|
|
|
|
### Cockpit
|
|
|
|
After the build, copy contents to `/usr/share/cockpit/tailscale`, `/usr/share/local/cockpit/tailscale` or `~/.local/share/cockpit/tailscale`.
|
|
|
|
#### Link development
|
|
|
|
For convenience, you can also create a symlink to `~/.local/share/cockpit/tailscale` to `$PWD/dist`. However, you will need to log out and log in because Cockpit caches the page and assets.
|
|
|
|
To create a link:
|
|
|
|
```bash
|
|
$ npm run link
|
|
```
|
|
|
|
And to remove:
|
|
|
|
```bash
|
|
$ npm run unlink
|
|
```
|
|
|
|
#### Run Cockpit
|
|
|
|
You can run Cockpit in a container or remote development environment with the following command:
|
|
|
|
```bash
|
|
$ npm run cockpit
|
|
```
|
|
|
|
You will need to use an account with a password to log in.
|
|
|
|
|
|
#### Origins
|
|
|
|
If the login fails and you see `bad Origin` errors, you need to modify the `/etc/cockpit/cockpit.conf` file and add something like:
|
|
|
|
```ini
|
|
[WebService]
|
|
Origins=https://jqgnyj-9090.csb.app
|
|
```
|
|
|
|
The example shows CodeSandbox. For Gitpod this might look like this:
|
|
```ini
|
|
[WebService]
|
|
Origins=https://9090-spotsnel-cockpittailsca-57e5sbbb0zb.ws-us100.gitpod.io
|
|
```
|
|
|
|
|
|
### Tailscale systemd image
|
|
You can run this as part of [spotsnel/tailscale-systemd](https://github.com/spotsnel/tailscale-systemd) container image to deploy this inside a Podman machine or similar:
|
|
```bash
|
|
$ tailscale ssh podmandesktop / podman exec -it tailscale-system bash
|
|
# dnf install -y cockpit passwd
|
|
# systemctl enable --now cockpit.socket
|
|
# curl -L https://github.com/spotsnel/cockpit-tailscale/releases/download/v0.0.1/cockpit-tailscale-v0.0.1.tar.gz -o dist.tar.gz
|
|
# tar zxvf dist.tar.gz
|
|
# mkdir /usr/local/share/cockpit
|
|
# mv dist /usr/local/share/cockpit/tailscale
|
|
# passwd root
|
|
# tailscale up --ssh
|
|
```
|
|
|
|
Now you can access the remote cockpit from another host by 'add new host'.
|
|
Note: remote hosts get authenticated over SSH. If you have conflicts, like on WSL, you can serve on `localhost` instead.
|
|
|
|
`/etc/systemd/system/cockpit.socket.d/listen.conf`
|
|
```ini
|
|
[Socket]
|
|
ListenStream=
|
|
ListenStream=127.0.0.1:9090
|
|
FreeBind=yes
|
|
```
|
|
|
|
Note: the blank `ListenStream` is intentional as it resets the parameter.
|
|
|
|
Now set up the forward from the Tailscale client to open port `9090`:
|
|
|
|
```bash
|
|
# tailscale serve tcp:9090 tcp://localhost:9090
|
|
# systemctl daemon-reload
|
|
# systemctl restart cockpit.socket
|
|
```
|
|
|
|
Now you can navigate to the Tailscale IP:
|
|
```
|
|
# tailscale ip -4
|
|
100.113.113.114
|
|
```
|
|
|
|
Open https://100.113.113.114:9090.
