Code-server is VS Code running on a remote server, accessible through the browser. You can code on your Chromebook, tablet, and laptop with a consistent dev environment using Code Server. You can take advantage of large cloud servers to speed up tests, compilations, downloads, and more. Code Server helps you preserve battery life when you’re on the go. All intensive computation runs on your NAS server; you’re no longer running excess instances of Chrome. In this step by step guide I will show you how to install Code Server on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest Code Server v4.96.2 release.

💡Note: Check out my new guide on how to Install Code Server Using Portainer.

• STEP 1

Please Support My work by Making a Donation.

• STEP 2

Install Container Manager via Synology “Package Center”. If you run an older DSM version (under 7.2), search for Docker instead of Container Manager.

-e TZ=Europe/Bucharest \
-e PASSWORD=mariushosting \
-e PROXY_DOMAIN=codeserver.yourname.synology.me \
-e SUDO_PASSWORD=mariushosting \
-v /volume1/docker/codeserver:/config \
--restart always \
ghcr.io/linuxserver/code-server

Note: Before you paste the code above in the Run command area below, change the value numbers for PUID and PGID with your own values. (Follow my step by step guide on how to do this.)
Note: Before you paste the code above in the Run command area below, change the value for TZ. (Select your current Time Zone from this list).
Note: Before you paste the code above in the Run command area, change the value for PASSWORD and add your own password. mariushosting is an example of a password. You have to insert your own password.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 16

Now open your browser and type in your HTTPS/SSL certificate like this https://codeserver.yourname.synology.me In my case it’s https://codeserver.mariushosting.synology.me Type in your own Password that you have previously chosen at STEP 12. Click SUBMIT. Follow the instructions in the image below.

• STEP 17

Check “Trust the authors of all files in the parent folder ‘config’“. Click Yes, I trust the authors. Follow the instructions in the image below.

• STEP 18

Choose the settings that appeal to you the most, like Dark theme, then click on Next Section.

• STEP 19
