# Generate a Certificate Using Let's Encrypt 🔒
|
|
|
|
To get around the certificate warnings in Chrome, you might want to install a
|
|
certificate from a trusted Certificate Authority (CA). Luckily, there are CAs
|
|
like [Let's Encrypt](lets-encrypt) which provide certificates for free.
|
|

### Using Certbot
|
|
|
|
[Certbot](certbot) is the program we'll be using to issue certificates from
|
|
Let's Encrypt.
|
|
|
|
> Pre-requisites: You will need a domain name or subdomain pointed to the IP
|
|
> address of your server.
|
|
|
|
1. Install Certbot by heading to the [instructions page](certbot-instructions).
|
|
Select **None of the above** for the software and the right operating system
|
|
for your setup.
|
|
2. Follow the installation instructions, and stop once you get up to the part
|
|
where you run the `certbot certonly` command.
|
|
3. Ensure your code-server instance isn't running, and any other webservers that
|
|
could interfere are also stopped.
|
|
4. Run the following command, replacing `code.example.com` with the
|
|
hostname/domain you want to run your server on, to issue a certificate:
|
|
```
|
|
sudo certbot certonly --standalone -d code.example.com
|
|
```
|
|
5. Follow the prompts, providing your email address and accepting the terms
|
|
where required.
|
|
6. Once the process is complete, it should print the paths to the certificates
|
|
and keys that were generated. You can now restart any webservers you stopped
|
|
in step 2.

### Starting code-server with a Certificate and Key
|
|
|
|
Just add the `--cert` and `--cert-key` flags when you run code-server:
|
|
|
|
```shell
|
|
./code-server --cert=/etc/letsencrypt/live/code.example.com/fullchain.pem --cert-key=/etc/letsencrypt/live/code.example.com/privkey.pem
|
|
```
|
|
|
|
You can now verify that your SSL installation is working properly by checking
|
|
your site with [SSL Labs' SSL Test](ssl-labs-test).

### Next Steps
|
|
|
|
You probably want to setup automatic renewal of your certificates, as they
|
|
expire every 3 months. You can find instructions on how to do this in
|
|
[Certbot's documentation](certbot-renew-docs).
