Please file all questions and support requests at <https://github.com/cdr/code-server/discussions>. ## How should I expose code-server to the internet? Please see [our instructions on exposing code-server safely to the internet](./guide.md). ## Can I use code-server on the iPad? See [iPad](./ipad.md) for information on using code-server on the iPad. ## How does the config file work? When `code-server` starts up, it creates a default config file in `~/.config/code-server/config.yaml`: ```yaml bind-addr: 127.0.0.1:8080 auth: password password: mew...22 # Randomly generated for each config.yaml cert: false ``` The default config defines the following behavior: - Listen on the loopback IP port 8080 - Enable password authorization - Do not use TLS Each key in the file maps directly to a `code-server` flag (run `code-server --help` to see a listing of all the flags). Any flags passed to `code-server` will take priority over the config file. You can change the config file's location using the `--config` flag or `$CODE_SERVER_CONFIG` environment variable. The default location respects `$XDG_CONFIG_HOME`. ## How do I make my keyboard shortcuts work? Many shortcuts will not work by default, since they'll be "caught" by the browser. If you use Chrome, you can work around this by installing the progressive web app (PWA): 1. Start the editor 2. Click the **plus** icon in the URL toolbar to install the PWA For other browsers, you'll have to remap keybindings for shortcuts to work. ## Why can't code-server use Microsoft's extension marketplace? Though code-server takes the open-source core of VS Code and allows you to run it in the browser, it is not entirely equivalent to Microsoft's VS Code. One major difference is in regards to extensions and the marketplace. The core of VS code is open source, while the marketplace and many published Microsoft extensions are not. Furthermore, Microsoft prohibits the use of any non-Microsoft VS Code from accessing their marketplace. Per the [Terms of Service](https://cdn.vsassets.io/v/M146_20190123.39/_content/Microsoft-Visual-Studio-Marketplace-Terms-of-Use.pdf): > Marketplace Offerings are intended for use only with Visual Studio Products > and Services, and you may only install and use Marketplace Offerings with > Visual Studio Products and Services. Because of this, we can't offer any extensions on Microsoft's marketplace. Instead, we've created a marketplace offering open-source extensions. The marketplace works by scraping GitHub for VS Code extensions and building them. These are the closed-source extensions that are presently unavailable: 1. [Live Share](https://visualstudio.microsoft.com/services/live-share). We may implement something similar (see [#33](https://github.com/cdr/code-server/issues/33)) 1. [Remote Extensions (SSH, Containers, WSL)](https://github.com/microsoft/vscode-remote-release). We may implement these again at some point, see ([#1315](https://github.com/cdr/code-server/issues/1315)). For more about the closed source portions of VS Code, see [vscodium/vscodium](https://github.com/VSCodium/vscodium#why-does-this-exist). ## How can I request an extension that's missing from the marketplace? We are in the process of transitioning to [Open VSX](https://open-vsx.org/). Once we've [implemented Open VSX](https://github.com/eclipse/openvsx/issues/249), we can finalize this transition. As such, we are not currently accepting new extension requests. In the meantime, we suggest: - [Switching to Open VSX](#how-do-i-configure-the-marketplace-url) now - Downloading and [installing the extension manually](#installing-an-extension-manually) ## How do I install an extension? You can install extensions from the marketplace using the extensions sidebar in code-server or from the command line: ```console code-server --install-extension <extension id> # example: code-server --install-extension wesbos.theme-cobalt2 # From the Coder extension marketplace code-server --install-extension ms-python.python # From a downloaded VSIX on the file system code-server --install-extension downloaded-ms-python.python.vsix ``` ## How do I install an extension manually? If there's an extension unavailable in the marketplace or an extension that doesn't work, you can download the VSIX from its GitHub releases or build it yourself. Once you have downloaded the VSIX to the remote machine, you can either: - Run the **Extensions: Install from VSIX** command in the Command Palette. - Run `code-server --install-extension <path to vsix>` in the terminal You can also download extensions using the command line. For instance, downloading from OpenVSX can be done like this: ```shell SERVICE_URL=https://open-vsx.org/vscode/gallery ITEM_URL=https://open-vsx.org/vscode/item code-server --install-extension <extension id> ``` ## How do I use my own extensions marketplace? If you own a marketplace that implements the VS Code Extension Gallery API, you can point code-server to it by setting `$SERVICE_URL` and `$ITEM_URL`. These correspond directly to `serviceUrl` and `itemUrl` in VS Code's `product.json`. For example, to use [open-vsx.org](https://open-vsx.org), run: ```bash export SERVICE_URL=https://open-vsx.org/vscode/gallery export ITEM_URL=https://open-vsx.org/vscode/item ``` Though you can technically use Microsoft's marketplace in this manner, we strongly discourage you from doing so since this is [against their Terms of Use](#why-cant-code-server-use-microsofts-extension-marketplace). For further information, see [this discussion](https://github.com/microsoft/vscode/issues/31168#issue-244533026) regarding the use of the Microsoft URLs in forks, as well as [VSCodium's docs](https://github.com/VSCodium/vscodium/blob/master/DOCS.md#extensions--marketplace). ## Where are extensions stored? Extensions are store, by default, to `~/.local/share/code-server/extensions`. If you set the `XDG_DATA_HOME` environment variable, the data directory will be `$XDG_DATA_HOME/code-server/extensions`. In general, we try to follow the XDG directory spec. ## How can I reuse my VS Code configuration? You can use the [Settings Sync](https://marketplace.visualstudio.com/items?itemName=Shan.code-settings-sync) extension for this purpose. Alternatively, you can also pass `--user-data-dir ~/.vscode` or copy `~/.vscode` into `~/.local/share/code-server` to reuse your existing VS Code extensions and configuration. ## How does code-server decide what workspace or folder to open? code-server tries the following in this order: 1. The `workspace` query parameter 2. The `folder` query parameter 3. The workspace or directory passed via the command line 4. The last opened workspace or directory ## How do I access my Documents/Downloads/Desktop folders in code-server on macOS? Newer versions of macOS require permission through a non-UNIX mechanism for code-server to access the Desktop, Documents, Pictures, Downloads, and other folders. You may have to give Node.js full disk access, since it doesn't implement any of the macOS permission request features natively: 1. Find where Node.js is installed on your machine ```console $ which node /usr/local/bin/node ``` 2. Grant Node.js full disk access. Open **System Preferences** > **Security & Privacy** > **Privacy** > **Full Disk Access**. Then, click the 🔒 to unlock, click **+**, and select the Node.js binary you located in the previous step. See [#2794](https://github.com/cdr/code-server/issues/2794) for additional context. ## How do I direct server-side requests through a proxy? > code-server proxies only server-side requests. To direct server-side requests through a proxy, code-server supports the following environment variables: - `$HTTP_PROXY` - `$HTTPS_PROXY` - `$NO_PROXY` ```sh export HTTP_PROXY=https://134.8.5.4 export HTTPS_PROXY=https://134.8.5.4 # Now all of code-server's server side requests will go through # https://134.8.5.4 first. code-server ``` - See [proxy-from-env](https://www.npmjs.com/package/proxy-from-env#environment-variables) for a detailed reference on these environment variables and their syntax (note that code-server only uses the `http` and `https` protocols). - See [proxy-agent](https://www.npmjs.com/package/proxy-agent) for information on on the supported proxy protocols. ## How do I debug issues with code-server? First, run code-server with the `debug` logging (or `trace` to be really thorough) by setting the `--log` flag or the `LOG_LEVEL` environment variable. `-vvv` and `--verbose` are aliases for `--log trace`. First, run code-server with `debug` logging (or `trace` logging for more thorough messages) by setting the `--log` flag or the `LOG_LEVEL` environment variable. ```text code-server --log debug ``` > Note that the `-vvv` and `--verbose` flags are aliases for `--log trace`. Next, replicate the issue you're having so that you can collect logging information from the following places: 1. The most recent files from `~/.local/share/code-server/coder-logs` 2. The browser console 3. The browser network tab Additionally, collecting core dumps (you may need to enable them first) if code-server crashes can be helpful. ## What is the healthz endpoint? You can use the `/healthz` endpoint exposed by code-server to check whether code-server is running without triggering a heartbeat. The response includes a status (e.g., `alive` or `expired`) and a timestamp for the last heartbeat (the default is `0`). ```json { "status": "alive", "lastHeartbeat": 1599166210566 } ``` This endpoint doesn't require authentication. ## What is the heartbeat file? As long as there is an active browser connection, code-server touches `~/.local/share/code-server/heartbeat` once a minute. If you want to shutdown code-server if there hasn't been an active connection after a predetermined amount of time, you can do so by checking continuously for the last modified time on the heartbeat file. If it is older than X minutes (or whatever amount of time you'd like), you can kill code-server. Eventually, [#1636](https://github.com/cdr/code-server/issues/1636) will make this process better. ## How do I change the password? Edit the `password` field in the code-server config file at `~/.config/code-server/config.yaml`, then restart code-server: ```bash sudo systemctl restart code-server@$USER ``` ## Can I store my password hashed? Yes, you can do so by setting the value of `hashed-password` instead of `password`. Generate the hash with: ```shell echo -n "thisismypassword" | npx argon2-cli -e $argon2i$v=19$m=4096,t=3,p=1$wst5qhbgk2lu1ih4dmuxvg$ls1alrvdiwtvzhwnzcm1dugg+5dto3dt1d5v9xtlws4 ``` Replace `thisismypassword` with your actual password and **remember to put it inside quotes**! For example: ```yaml auth: password hashed-password: "$argon2i$v=19$m=4096,t=3,p=1$wST5QhBgk2lu1ih4DMuxvg$LS1alrVdIWtvZHwnzCM1DUGg+5DTO3Dt1d5v9XtLws4" ``` The `hashed-password` field takes precedence over `password`. ## Is multi-tenancy possible? If you want to run multiple code-servers on shared infrastructure, we recommend using virtual machines (provide one VM per user). This will easily allow users to run a Docker daemon. If you want to use Kubernetes, you'll want to use [kubevirt](https://kubevirt.io) or [sysbox](https://github.com/nestybox/sysbox) to give each user a VM-like experience instead of just a container. ## Can I use Docker in a code-server container? If you'd like to access Docker inside of code-server, mount the Docker socket in from `/var/run/docker.sock`. Then, install the Docker CLI in the code-server container, and you should be able to access the daemon. You can even make volume mounts work. Let's say you want to run a container and mount into `/home/coder/myproject` from inside the `code-server` container. You need to make sure the Docker daemon's `/home/coder/myproject` is the same as the one mounted inside the `code-server` container, and the mount will work. ## How do I disable telemetry? Use the `--disable-telemetry` flag to disable telemetry. > We use the data collected only to improve code-server. ## What's the difference between code-server and Theia? At a high level, code-server is a patched fork of VS Code that runs in the browser whereas Theia takes some parts of VS Code but is an entirely different editor. [Theia](https://github.com/eclipse-theia/theia) is a browser IDE loosely based on VS Code. It uses the same text editor library ([Monaco](https://github.com/Microsoft/monaco-editor)) and extension API, but everything else is different. Theia also uses [Open VSX](https://open-vsx.org) for extensions. Theia doesn't allow you to reuse your existing VS Code config. ## What's the difference between code-server and VS Code Codespaces? Both code-server and VS Code Codespaces allow you to access VS Code via a browser. VS Code Codespaces, however, is a closed-source, paid service offered by Microsoft. While you can self-host environments with VS Code Codespaces, you still need an Azure billing account, and you must access VS Code via the Codespaces web dashboard instead of connecting directly to it. On the other hand, code-server is free, open-source, and can be run on any machine with few limitations. ## Does code-server have any security login validation? code-server supports setting a single password and limits logins to two per minute plus an additional twelve per hour. ## Are there community projects involving code-server?
