16 The 'ssh' command is used to SSH into a codespace. In its simplest
17 form, you can run 'gh cs ssh', select a codespace interactively, and
18 connect.

21 The 'ssh' command will automatically create a public/private ssh key
22 pair in the ~/.ssh directory if you do not have an existing valid key
23 pair. When selecting the key pair to use, the preferred order is:
24
25
26 1. Key specified by -i in
27
28 2. Automatic key, if it already exists
29
30 3. First valid key pair in ssh config (according to ssh -G)
31
32 4. Automatic key, newly created
33
34
35
36 The 'ssh' command also supports deeper integration with OpenSSH using a
37 '--config' option that generates per-codespace ssh configuration in
38 OpenSSH format. Including this configuration in your ~/.ssh/config im‐
39 proves the user experience of tools that integrate with OpenSSH, such
40 as bash/zsh completion of ssh hostnames, remote path completion for
41 scp/rsync/sshfs, git ssh remotes, and so on.
42
43
44 Once that is set up (see the second example below), you can ssh to
45 codespaces as if they were ordinary remote hosts (using 'ssh', not 'gh
46 cs ssh').
47
48
49 Note that the codespace you are connecting to must have an SSH server
50 pre-installed. If the docker image being used for the codespace does
51 not have an SSH server, install it in your Dockerfile or, for
52 codespaces that use Debian-based images, you can add the following to
53 your devcontainer.json:
54
55
56 "features": { "ghcr.io/devcontainers/features/sshd:1": {
57 "version": "latest" } }
