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 v4.16.1 release.

• 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.

• STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it codeserver. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4 

Activate your synology.me Wildcard Certificate. If you already have a synology.me Wildcard certificate installed on your Synology NAS, skip this STEP.

• STEP 5

Go to Control Panel / Login Portal / Advanced Tab / click Reverse Proxy. Follow the instructions in the image below.

• STEP 6

Now click the “Create” button. Follow the instructions in the image below.

• STEP 7

After you click the Create button, the window below will open. Follow the instructions in the image below.

On the General area, set the Reverse Proxy Name description: type in Code Server. After that, add the following instructions:

Source:
Protocol: HTTPS
Hostname: codeserver.yourname.synology.me
Port: 443

Check Enable HSTS

Destination:
Protocol: HTTP
Hostname: localhost
Port: 8377

• STEP 8

Go to Control Panel / Login Portal / select your Code Server Reverse Proxy then click the Custom Header tab. Click Create and then, from the drop-down menu, click on WebSocket. After you click on WebSocket, two Header Names and two Values will be automatically added. Click Save. Follow the instructions in the image below.

• STEP 9

Go to Control Panel / Task Scheduler / Create / Scheduled Task / User-defined script. Follow the instructions in the images below.

• STEP 10

Once you click on User-defined script a new window will open. Follow the instructions below:

1. General: In the Task field type in Install Code Server. Uncheck the “Enabled” option. Select root User.
2. Schedule: Select Run on the following date then select “Do not repeat“.
3. Task Settings: Check “Send run details by email“, add your email then copy paste the code below in the Run command area. After that click OK.

docker run -d --name=codeserver \
-p 8377:8443 \
-e PUID=1026 \
-e PGID=100 \
-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.
Note: Before you paste the code above in the Run command area, change the value for PROXY_DOMAIN and add your own synology.me DDNS that you have previously created at STEP 7.
Note: Before you paste the code above in the Run command area, change the value for SUDO_PASSWORD and add your own password. mariushosting is an example for a sudo password. You have to insert your own sudo password.

• STEP 11

After you click OK on STEP 10 a new warning pop up window will open. Click OK.

After you click OK, type in your DSM Password then click Submit. Follow the instructions in the image below.

• STEP 12

After you click Submit on STEP 11, select your “Install Code Server” Task then click the “Run” tab. You will be asked to run Install Code Server – click OK. Follow the instructions in the image below.

• STEP 13

Go back to STEP 1 or you will deal with karma 🙂

• STEP 14

Now open your browser and type in your HTTPS/SSL https://codeserver.yourname.synology.me address, in my case: https://codeserver.mariushosting.synology.me
If everything goes right, you will get to the log in page. Add your own Password which you have chosen at STEP 10. Click SUBMIT. Follow the instructions in the image below.

• STEP 15

Choose the settings that appeal to you the most then click on Next Section.

Enjoy Code Server!
