How to use code-server to build your own cloud VSCode?

Recently, I always have to carry a computer when I go out to study, which is quite tiring, but I A computer is required for programming. Is there any way I can just take my iPad out and program at the same time?

The answer is the open source project code-server, through which VS Code can be run on the browser. Below I will introduce how to use code-server to build your cloud VS Code.

Goal

Run VS Code on your server through code-server, and then access VS Code through the browser.

Server

First you need to prepare a server. The minimum configuration recommended by the official documentation is

• 1 GB of RAM
• 2 cores ( 1 Nuclear can run, but sometimes it gets stuck)

If you don’t have a server yet, it is recommended to buy Tencent Cloud (Conscience Cloud) server in China; it is recommended to buy Vultr abroad, which is billed by volume and has a good line. Support WeChat/Alipay. If you want to support me, you can use my AFF link and you will get a $100 credit and I will get a $25 credit.

The operating system can use any Linux distribution you like. This article uses Ubuntu 20.04 as an example.

Install code-server

We will install code-server through the official script. Use XShell or Putty to log in to your server, and then run the following commands in sequence:

curl -fsSL https://code-server.dev/install.sh | sh -s -- --dry-run
curl -fsSL https://code-server.dev/install.sh | sh

After completion, the installation script will print out how to run and use code-server.

systemctl start code-server@$USER // 启动code-server

Access code-server

code-server uses a password to log in by default (the password is saved in ~/.config/code-server/config.yaml), and monitors losthost thus avoids exposing itself to the outside world. But our goal is to access it on different machines.

Below I will introduce a safe and simple method to access code-server.

Before going further, you need to ensure that the server opens the HTTP/HTTPS port

ufw allow 80
ufw allow 443

1. A domain name of your own (you have already seen this, I believe you also have a domain name. If you don’t have one yet, you might consider purchasing one (I use NameCheap, the Github student package comes with a free NameCheap domain for one year).

2. Use A records to resolve your domain name to the server IP.

3. Install Caddy.

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

Caddy server is an open source web server written in Golang that supports HTTP/2. It uses the Golang standard library to provide HTTP functionality. A notable feature of Caddy is that HTTPS is enabled by default. It is the first web server to provide HTTPS features without additional configuration.

——Wikipedia

Note: The above method installs Caddy 2, and most of the Caddy documents currently searched on the Chinese Internet are version 1. There are many differences between 2 and 1. Please check it yourself. Official English documentation.

4. nano /etc/caddy/Caddyfile, replace the content with the following

yourdomain.com
reverse_proxy 127.0.0.1:8080

5. Restart caddy:

sudo systemctl reload caddy

Then visit https://<your-domain-name> in the browser to enter your code-server page!

Change Password

Just modify the value of password in ~/.config/code-server/config.yaml, and then restart code-server:

sudo systemctl restart code-server@$USER
