# VS Code extensions
This article will show you the ways to add VS Code extensions and use them with
a Coder workspace:
1. Using the
[public extensions marketplaces](vscode-extensions.md#using-the-public-extensions-marketplaces)
with Code Web (code-server)
1. Adding
[extensions to custom images](vscode-extensions.md#adding-extensions-to-custom-images)
1. Installing extensions
[using its `vsix` file at the command line](vscode-extensions.md#installing-extensions-using-its-vsix-file-at-the-command-line)
1. Installing extensions
[from a marketplace using the command line](vscode-extensions.md#installing-from-a-marketplace-at-the-command-line)
1. Using a
[local VS Code instance with SSH](vscode-extensions.md#using-a-local-vs-code-instance-with-ssh)
## Using the public extensions marketplaces
You can manually add an extension while you're working in the Code Web IDE. The
extensions can be from Coder's public marketplace, Eclipse Open VSX's public
marketplace, or the Eclipse Open VSX _local_ marketplace.

> Note: Microsoft does not allow any unofficial VS Code IDE to connect to the
> extension marketplace.
## Adding extensions to custom images
You can add extensions to a custom image and install them either through Code
Web or using the workspace's terminal.
1. Download the extension(s) from the Microsoft public marketplace.
![Code Web Extensions](../images/ides/copilot.png)
1. Add the `vsix` extension files to the same folder as your Dockerfile.
```shell
~/images/base
➜ ls -l
-rw-r--r-- 1 coder coder 0 Aug 1 19:23 Dockerfile
-rw-r--r-- 1 coder coder 8925314 Aug 1 19:40 GitHub.copilot.vsix
```
1. In the Dockerfile, add instructions to make a folder and to copy the `vsix`
files into the newly created folder.
```Dockerfile
FROM codercom/enterprise-base:ubuntu
# Run below commands as root user
USER root
# Download and install VS Code extensions into the container
RUN mkdir -p /vsix
ADD ./GitHub.copilot.vsix /vsix
USER coder
```
1. Build the custom image, and push it to your image registry.
1. Pass in the image and below command into your template `startup_script` (be
sure to update the filename below):
**Startup Script**
```hcl
resource "coder_agent" "main" {
...
startup_script = "code-server --install-extension /vsix/Github.copilot.vsix"
}
```
**Image Definition**
```hcl
resource "kubernetes_deployment" "main" {
spec {
template {
spec {
container {
name = "dev"
image = "registry.internal/image-name:tag"
}
}
}
}
}
```
1. Create a workspace using the template.
You will now have access to the extension in your workspace.
## Installing extensions using its `vsix` file at the command line
Using the workspace's terminal or the terminal available inside `code-server`,
you can install an extension whose files you've downloaded from a marketplace:
```console
/path/to/code-server --install-extension /vsix/Github.copilot.vsix
```
## Installing from a marketplace at the command line
Using the workspace's terminal or the terminal available inside Code Web (code
server), run the following to install an extension (be sure to update the
snippets with the name of the extension you want to install):
```console
SERVICE_URL=https://extensions.coder.com/api ITEM_URL=https://extensions.coder.com/item /path/to/code-server --install-extension GitHub.copilot
```
Alternatively, you can install an extension from Open VSX's public marketplace:
```console
SERVICE_URL=https://open-vsx.org/vscode/gallery ITEM_URL=https://open-vsx.org/vscode/item /path/to/code-server --install-extension GitHub.copilot
```
## Using VS Code Desktop
For your local VS Code to pickup extension files in your Coder workspace,
include this command in your `startup_script`, or run in manually in your
workspace terminal:
```console
code --extensions-dir ~/.vscode-server/extensions --install-extension "$extension"
```
