GitHub CLI is an open source tool for using GitHub from your computer's command line. When you're working from the command line, you can use the GitHub CLI to save time and avoid switching context. For more information, see "About GitHub CLI."
You can work with Codespaces in the GitHub CLI to:
- List all of your codespaces
- Create a new codespace
- Stop a codespace
- Delete a codespace
- SSH into a codespace
- Open a codespace in Visual Studio Code
- Open a codespace in JupyterLab
- Copy a file to/from a codespace
- Modify ports in a codespace
- Access codespace logs
- Access remote resources
For installation instructions for GitHub CLI, see the GitHub CLI repository.
If you have not already done so, run
gh auth login to authenticate with your GitHub account.
gh to work with Codespaces, type
gh codespace <COMMAND> or its alias
gh cs <COMMAND>.
As an example of a series of commands you might use to work with GitHub Codespaces, you could:
- List your current codespaces, to check whether you have a codespace for a particular repository:
gh codespace list
- Create a new codespace for the required repository branch:
gh codespace create -r github/docs -b main
- SSH into the new codespace:
gh codespace ssh -c mona-github-docs-v4qxrv7rfwv9w
- Forward a port to your local machine:
gh codespace ports forward 8000:8000 -c mona-github-docs-v4qxrv7rfwv9w
The sections below give example commands for each of the available operations.
For a complete reference of
gh commands for GitHub Codespaces, including details of all available options for each command, see the GitHub CLI online help for "gh codespace." Alternatively, use
gh codespace [<SUBCOMMAND>...] --help on the command line.
-c <em>codespace-name</em> flag, used with many commands, is optional. If you omit it a list of codespaces is displayed for you to choose from.
gh codespace list
The list includes the unique name of each codespace, which you can use in other
gh codespace commands.
gh codespace create -r owner/repository [-b branch]
For more information, see "Creating a codespace."
gh codespace stop -c codespace-name
For more information, see "Deep dive into GitHub Codespaces."
gh codespace delete -c codespace-name
For more information, see "Deleting a codespace."
To run commands on the remote codespace machine, from your terminal, you can SSH into the codespace.
gh codespace ssh -c codespace-name
GitHub Codespaces copies your GitHub SSH keys into the codespace on creation for a seamless authentication experience. You may be asked to enter the passphrase for your SSH key, after which you will get a command prompt from the remote codespace machine.
If you don't have any SSH keys, follow the instructions in "Generating a new SSH key and adding it to the ssh-agent."
gh codespace code -c codespace-name
For more information, see "Using Codespaces in Visual Studio Code."
gh codespace jupyter -c codespace-name
gh codespace cp [-r] source(s) destination
Use the prefix
remote: on a file or directory name to indicate that it's on the codespace. As with the UNIX
cp command, the first argument specifies the source and the last specifies the destination. If the destination is a directory, you can specify multiple sources. Use the
-r (recursive) flag if any of the sources is a directory.
The location of files and directories on the codespace is relative to the home directory of the remote user.
Copy a file from the local machine to the
$HOMEdirectory of a codespace:
gh codespace cp myfile.txt remote:
Copy a file to the directory in which a repository is checked out in a codespace:
gh codespace cp myfile.txt remote:/workspaces/<REPOSITORY-NAME>
Copy a file from a codespace to the current directory on the local machine:
gh codespace cp remote:myfile.txt .
Copy three local files to the
$HOME/tempdirectory of a codespace:
gh codespace cp a1.txt a2.txt a3.txt remote:temp
Copy three files from a codespace to the current working directory on the local machine:
gh codespace cp remote:a1.txt remote:a2.txt remote:a3.txt .
Copy a local directory into the
$HOMEdirectory of a codespace:
gh codespace cp -r mydir remote:
Copy a directory from a codespace to the local machine, changing the directory name:
gh codespace cp -r remote:mydir mydir-localcopy
For more information about the
gh codespace cp command, including additional flags you can use, see the GitHub CLI manual.
You can forward a port on a codespace to a local port. The port remains forwarded as long as the process is running. To stop forwarding the port, press Control+C.
gh codespace ports forward codespace-port-number:local-port-number -c codespace-name
To see details of forwarded ports enter
gh codespace ports and then choose a codespace.
You can set the visibility of a forwarded port. There are three visibility settings:
private- Visible only to you. This is the default setting when you forward a port.
org- Visible to members of the organization that owns the repository.
public- Visible to anyone who knows the URL and port number.
gh codespace ports visibility codespace-port:private|org|public -c codespace-name
You can set the visibility for multiple ports with one command. For example:
gh codespace ports visibility 80:private 3000:public 3306:org -c codespace-name
For more information, see "Forwarding ports in your codespace."
You can see the creation log for a codespace. After entering this command you will be asked to enter the passphrase for your SSH key.
gh codespace logs -c codespace-name
For more information about the creation log, see "GitHub Codespaces logs."
You can use the GitHub CLI extension to create a bridge between a codespace and your local machine, so that the codespace can access any remote resource that is accessible from your machine. For more information on using the extension, see "Using GitHub CLI to access remote resources."
Note: The GitHub CLI extension is currently in beta and subject to change.
