This guide demonstrates how to setup and use code-server.
|
||||
To reiterate, code-server lets you run VS Code on a remote server and then access it via a browser.
|
||||
|
||||
See the [README](../README.md) for a general overview and the [FAQ](./FAQ.md) for further user docs.
|
||||
|
||||
We'll walk you through acquiring a remote machine to run code-server on and then exposing `code-server` so you can
|
||||
easily access it.
|
||||
|
||||
## 1. Acquire a remote machine
|
||||
|
||||
First, you need a machine to run code-server on. You can use a physical
|
||||
machine you have lying around or use a VM on GCP/AWS.
|
||||
|
||||
### Requirements
|
||||
|
||||
For a good experience, we recommend at least:
|
||||
|
||||
- 1 GB of RAM
|
||||
- 2 cores
|
||||
|
||||
You can use whatever linux distribution floats your boat but in this guide we assume Debian.
|
||||
|
||||
### Google Cloud Platform
|
||||
|
||||
For demonstration purposes, this guide assumes you're using a VM on GCP but you should be
|
||||
able to easily use any machine or VM provider.
|
||||
|
||||
You can sign up at https://console.cloud.google.com/getting-started. You'll get a 12 month \$300
|
||||
free trial.
|
||||
|
||||
Once you've signed up and created a GCP project, create a new Compute Engine VM Instance.
|
||||
|
||||
1. Navigate to `Compute Engine -> VM Instances` on the sidebar
|
||||
2. Now click `Create Instance` to create a new instance
|
||||
3. Choose the region closest to you based on [gcping.com](http://www.gcping.com)
|
||||
4. Name it whatever you want
|
||||
5. Any zone is fine
|
||||
6. We'd recommend a `e2-standard-2` instance from the E2 series and General-purpose family
|
||||
- Add more vCPUs and memory as you prefer, you can edit after creating the instance as well
|
||||
- https://cloud.google.com/compute/docs/machine-types#general_purpose
|
||||
7. We highly recommend switching the persistent disk to a SSD of at least 32 GB
|
||||
8. Navigate to `Networking -> Network interfaces` and edit the existing interface
|
||||
to use a static external IP
|
||||
- Click done to save network interface changes
|
||||
9. If you do not have a [project wide SSH key](https://cloud.google.com/compute/docs/instances/adding-removing-ssh-keys#project-wide), navigate to `Security - > SSH Keys` and add your public key there
|
||||
10. Click create!
|
||||
|
||||
Remember, you can shutdown your server when not in use to lower costs.
|
||||
We highly recommend learning to use the [`gcloud`](https://cloud.google.com/sdk/gcloud) cli
|
||||
to avoid the slow dashboard.
|
||||
|
||||
## 2. Install code-server
|
||||
|
||||
SSH into your instance and run the appropriate commands documented in [README.md](../README.md).
|
||||
|
||||
Assuming Debian:
|
||||
|
||||
```bash
|
||||
curl -sSOL https://github.com/cdr/code-server/releases/download/3.3.0/code-server_3.3.0_amd64.deb
|
||||
sudo dpkg -i code-server_3.3.0_amd64.deb
|
||||
systemctl --user enable --now code-server
|
||||
# Now code-server is running at http://127.0.0.1:8080
|
||||
# Your password is in ~/.config/code-server/config.yaml
|
||||
```
|
||||
|
||||
## 3. Expose code-server
|
||||
|
||||
There are several approaches to operating and exposing code-server.
|
||||
|
||||
Since you can gain access to a terminal from within code-server, **never**, **ever**
|
||||
expose it directly to the internet without some form of authentication and encryption!
|
||||
|
||||
By default, code-server will enable password authentication which will
|
||||
require you to copy the password from the code-server config file to login. You
|
||||
can also set a custom password with `$PASSWORD`.
|
||||
|
||||
**tip**: You can list the full set of code-server options with `code-server --help`
|
||||
|
||||
### SSH forwarding
|
||||
|
||||
We highly recommend this approach for not requiring any additional setup, you just need an
|
||||
SSH server on your remote machine. The downside is you won't be able to access `code-server`
|
||||
without an SSH client like an iPad. If that's important to you, skip to [Let's Encrypt](#lets-encrypt).
|
||||
|
||||
Recommended reading: https://help.ubuntu.com/community/SSH/OpenSSH/PortForwarding
|
||||
|
||||
```bash
|
||||
# -N disables executing a remote shell
|
||||
ssh -N -L 8080:127.0.0.1:8080 <instance-ip>
|
||||
```
|
||||
|
||||
As long as this command hasn't exited, that means any request on local port 8080 goes to your
|
||||
instance at `127.0.0.1:8080` which is where code-server is running.
|
||||
|
||||
Next ssh into your instance and edit your code-server config file to disable password authentication.
|
||||
|
||||
```bash
|
||||
# Replaces "auth: password" with "auth: none" in the code-server config.
|
||||
sed -i.bak 's/auth: password/auth: none/' ~/.config/code-server/config.yaml
|
||||
```
|
||||
|
||||
Restart code-server with (assuming you followed the guide):
|
||||
|
||||
```bash
|
||||
systemctl --user restart code-server
|
||||
```
|
||||
|
||||
Now if you access http://127.0.0.1:8080 locally, you should see code-server!
|
||||
|
||||
If you want to make the SSH port forwarding persistent we recommend using
|
||||
[mutagen](https://mutagen.io/documentation/introduction/installation).
|
||||
|
||||
```
|
||||
# Same as the above SSH command but runs in the background continously.
|
||||
# Add `mutagen daemon start` to your ~/.bashrc to start the mutagen daemon when you open a shell.
|
||||
mutagen forward create --help -n=code-server tcp:127.0.0.1:8080 <instance-ip>:tcp:127.0.0.1:8080
|
||||
```
|
||||
|
||||
We also recommend adding the following lines to your `~/.ssh/config` to quickly detect bricked SSH connections:
|
||||
|
||||
```bash
|
||||
Host *
|
||||
ServerAliveInterval 5
|
||||
ExitOnForwardFailure yes
|
||||
```
|
||||
|
||||
You can also forward your SSH key and GPG agent to the instance to securely access GitHub
|
||||
and sign commits without copying your keys onto the instance.
|
||||
|
||||
1. https://developer.github.com/v3/guides/using-ssh-agent-forwarding/
|
||||
2. https://wiki.gnupg.org/AgentForwarding
|
||||
|
||||
### Let's Encrypt
|
||||
|
||||
Let's Encrypt is a great option if you want to access code-server on an iPad or just want password
|
||||
based authentication. This does require that the remote machine is exposed to the internet.
|
||||
|
||||
Assuming you have been following the guide, edit your instance and checkmark the allow HTTP/HTTPS traffic options.
|
||||
|
||||
1. You'll need to buy a domain name. We recommend [Google Domains](https://domains.google.com)
|
||||
2. Add an A record to your domain with your instance's IP
|
||||
3. Install caddy https://caddyserver.com/docs/download#debian-ubuntu-raspbian
|
||||
|
||||
```bash
|
||||
echo "deb [trusted=yes] https://apt.fury.io/caddy/ /" \
|
||||
| sudo tee -a /etc/apt/sources.list.d/caddy-fury.list
|
||||
sudo apt update
|
||||
sudo apt install caddy
|
||||
```
|
||||
|
||||
4. Replace `/etc/caddy/Caddyfile` with sudo to look like this:
|
||||
|
||||
```
|
||||
mydomain.com
|
||||
|
||||
reverse_proxy 127.0.0.1:8080
|
||||
```
|
||||
|
||||
5. Reload caddy with:
|
||||
|
||||
```bash
|
||||
sudo systemctl reload caddy
|
||||
```
|
||||
|
||||
Visit `https://<your-instance-ip>` to access code-server. Congratulations!
|
||||
|
||||
In a future release we plan to integrate Let's Encrypt directly with code-server to avoid
|
||||
the dependency on caddy.
|
||||
|
||||
### Self Signed Certificate
|
||||
|
||||
**note:** Self signed certificates do not work with iPad and will cause a blank page. You'll
|
||||
have to use [Let's Encrypt](#lets-encrypt) instead.
|
||||
|
||||
Recommended reading: https://security.stackexchange.com/a/8112
|
||||
|
||||
We recommend this as a last resort as self signed certificates do not work with iPads and can
|
||||
cause other bizarre issues. Not to mention all the warnings when you access code-server.
|
||||
Only use this if you do not want to buy a domain or cannot expose the remote machine to the internet.
|
||||
|
||||
ssh into your instance and edit your code-server config file to use a randomly generated self signed certificate:
|
||||
|
||||
```bash
|
||||
# Replaces "cert: false" with "cert: true" in the code-server config.
|
||||
sed -i.bak 's/cert: false/cert: true/' ~/.config/code-server/config.yaml
|
||||
# Replaces "bind-addr: 127.0.0.1:8080" with "bind-addr: 0.0.0.0:443" in the code-server config.
|
||||
sed -i.bak 's/bind-addr: 127.0.0.1:8080/bind-addr: 0.0.0.0:443/' ~/.config/code-server/config.yaml
|
||||
# Allows code-server to listen on port 443.
|
||||
sudo setcap cap_net_bind_service=+ep /usr/lib/code-server/lib/node
|
||||
```
|
||||
|
||||
Assuming you have been following the guide, restart code-server with:
|
||||
|
||||
```bash
|
||||
systemctl --user restart code-server
|
||||
```
|
||||
|
||||
Edit your instance and checkmark the allow HTTPS traffic option.
|
||||
|
||||
Visit `https://<your-instance-ip>` to access code-server.
|
||||
You'll get a warning when accessing but if you click through you should be good.
|
||||
|
||||
You can also use [mkcert](https://mkcert.dev) to create a self signed certificate trusted by your
|
||||
OS to avoid the warnings.
|
||||
|
||||
### Change the password?
|
||||
|
||||
Edit the code-server config file at `~/.config/code-server/config.yaml` and then restart
|
||||
code-server with:
|
||||
|
||||
```bash
|
||||
systemctl --user restart code-server
|
||||
```
|
||||
|
||||
### How do I securely access development web services?
|
||||
|
||||
If you're working on a web service and want to access it locally, code-server can proxy it for you.
|
||||
|
||||
See the [FAQ](https://github.com/cdr/code-server/blob/master/doc/FAQ.md#how-do-i-securely-access-web-services).
