How to access code-server with a self signed certificate on iPad?

Accessing a self signed certificate on iPad isn't as easy as accepting through all the security warnings. Safari will prevent WebSocket connections unless the certificate is installed as a profile on the device.

The below assumes you are using the self signed certificate that code-server generates for you. If not, that's fine but you'll have to make sure your certificate abides by the following guidelines from Apple: https://support.apple.com/en-us/HT210176

note: Another undocumented requirement we noticed is that the certificate has to have basicConstraints=CA:true.

The following instructions assume you have code-server installed and running with a self signed certificate. If not, please first go through ./guide.md!

warning: Your iPad must access code-server via a domain name. It could be local DNS like mymacbookpro.local but it must be a domain name. Otherwise Safari will refuse to allow WebSockets to connect.

1. Your certificate must have a subject alt name that matches the hostname at which you will access code-server from your iPad. You can pass this to code-server so that it generates the certificate correctly with --cert-host.
2. Share your self signed certificate with the iPad.
   • code-server will print the location of the certificate it has generated in the logs.

[2020-10-30T08:55:45.139Z] info    - Using generated certificate and key for HTTPS: ~/.local/share/code-server/mymbp_local.crt

• You can mail it to yourself or if you have a Mac, it's easiest to just Airdrop to the iPad.

3. When opening the *.crt file, you'll be prompted to go into settings to install.
4. Go to Settings -> General -> Profile, select the profile and then hit Install.
   • It should say the profile is verified.
5. Go to Settings -> About -> Certificate Trust Settings and enable full trust for the certificate. more apple support here
6. Now you can access code-server! 🍻

Servediter iPad App

If you are unable to get the self signed certificate working or you do not have a domain name to use, you can use the Servediter iPad App instead!

note: This is not an officially supported app by the code-server team!

Download Serveediter from the App Store and then input your server information. If you are running a local server or mabye a usb-c connected Raspberry Pi, you will input your settings into "Self Hosted Server".

Raspberry Pi USB-C Network

It is a bit out of scope for this project, however, great success is being reported using iPad on the go with just a single USB-C cable connected to a Raspberry Pi both powering and supplying direct network access. Many support articles already exist but the key steps boil down to turning on Network over USB-C on the Raspberry Pi itself and the rest of the steps are just like getting Code Server running any where else.

Here are my keys to success. I bought a 4" touch screen with fan included that attaches as a case to the Pi. I use the touch screen for anytime I have connection issues, otherwise I turn off the Pi screen. I gave my Pi a network name so I can easily connect at home on wifi or when on go with 1 usb-c cable supplying power and network. LASTLY, not all usb-c cables are equal and not all will work so try different usb-c cables if you are going mad (confirm over wifi first then move to cable).
