Questions?
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.
Can I use code-server on the iPad?
See iPad 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
:
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):
- Start the editor
- 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:
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:
- Live Share. We may implement something similar (see #33)
- Remote Extensions (SSH, Containers, WSL). We may implement these again at some point, see (#1315).
For more about the closed source portions of VS Code, see vscodium/vscodium.
How can I request an extension that's missing from the marketplace?
We are in the process of transitioning to Open VSX. Once we've implemented Open VSX, we can finalize this transition. As such, we are not currently accepting new extension requests.
In the meantime, we suggest:
- Switching to Open VSX now
- Downloading and installing the 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:
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:
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, run:
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.
For further information, see this discussion regarding the use of the Microsoft URLs in forks, as well as VSCodium's docs.
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 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:
- The
workspace
query parameter - The
folder
query parameter - The workspace or directory passed via the command line
- 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:
-
Find where Node.js is installed on your machine
$ which node /usr/local/bin/node
-
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 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
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
for a detailed reference on these environment variables and their syntax (note
that code-server only uses the
http
andhttps
protocols). - See 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.
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:
- The most recent files from
~/.local/share/code-server/coder-logs
- The browser console
- 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
).
{
"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 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:
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:
echo -n "thisismypassword" | npx argon2-cli -e
$argon2i$v=19$m=4096,t=3,p=1$wst5qhbgk2lu1ih4dmuxvg$ls1alrvdiwtvzhwnzcm1dugg+5dto3dt1d5v9xtlws4
Replace thisismypassword
with your actual password and remember to put it
inside quotes! For example:
auth: password
hashed-password: "$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 or 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 is a browser IDE loosely based on VS Code. It uses the same text editor library (Monaco) and extension API, but everything else is different. Theia also uses Open VSX for extensions.
Theia doesn't allow you to reuse your existing VS Code config.
What's the difference between code-server and OpenVSCode-Server?
code-server and OpenVSCode-Server both allow you to access VS Code via a browser. The two projects also use their own forks of VS Code to leverage modern VS Code APIs and stay up to date with the upsteam version.
However, OpenVSCode-Server is scoped at only making VS Code avalible in the web browser. code-server includes some other features:
- password auth
- proxy web ports
- certificate support
- plugin API
- settings sync (coming soon)
For more details, see this discussion post.
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. Codespaces are hosted in Microsoft's cloud.
On the other hand, code-server is self-hosted, 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?
Visit the awesome-code-server repository to view community projects and guides with code-server! Feel free to add your own!
How do I change the port?
There are two ways to change the port on which code-server runs:
- with an environment variable e.g.
PORT=3000 code-server
- using the flag
--bind-addr
e.g.code-server --bind-addr localhost:3000
