Dev Containers: error "ssh: connect to host github.com port 22: Connection refused" when using git pull in vscode that is attaching to a runing docker container locally

[stunited-thien]

• VSCode Version: 1.89.1
• Local OS Version: windows 11
• Remote OS Version: node:16.18.0-alpine
• Remote Extension/Connection Type: Dev Containers

I already followed attaching container and sharing git ssh. But I got the above error.
Here is the result of each command I used in the attached container to get info:

• ssh-agent

SSH_AUTH_SOCK=/tmp/ssh-XXXXXXKIFeKn/agent.48633; export SSH_AUTH_SOCK;
SSH_AGENT_PID=48634; export SSH_AGENT_PID;
echo Agent pid 48634;

• echo $SSH_AUTH_SOCK

/tmp/vscode-ssh-auth-a64e1ad3-e58a-4012-b353-cd26f1e4a27b.sock

• ps -ef | grep ssh-agent

48634 root      0:00 ssh-agent 
50834 root      0:00 grep ssh-agent

Here is my .giconfig in the attached container:

[user]
	name = myname
	email = myemail@.com
[gui]
	recentrepo = F:/my-other-project
[safe]
	directory = F:/my-other-project
	directory = .
[credential]
	helper = "!f() { /root/.vscode-server/bin/dc96b837cf6bb4af9cd736aa3af08cf8279f7685/node /tmp/vscode-remote-containers-a64e1ad3-e58a-4012-b353-cd26f1e4a27b.js git-credential-helper $*; }; f"

Does this issue occur when you try this locally?: No
Does this issue occur when you try this locally and all extensions are disabled?: No

Since your local machine is Windows, please only follow the instructions for Windows on your local machine (not the container). E.g., you do not need to start ssh-agent in the container. To check if the connection to the local ssh-agent works, you can run ssh-add -l in the container.

The error you copied suggests that there is a network issue between the container and github.com. It doesn't hint at a problem with the local ssh-agent connection.

My Windows local runs git fine and the local ssh-agent works (I checked it with ssh-add -l ). Only when I attached and ran my local project via the dev containers, I couldn't run git (even though the Git Graph extension still shows my git graph tree, it just can't use git fetch)

What to you get when running ssh-add -l in the dev container? (Without running ssh-agent in the dev container.)

I only followed the above instructions for my window, not the dev container but the result of ssh-add -l ran in both window terminal and container ash was the same: 256 SHA256:YPAqj/Ft6imz8lL9UsI9vbCuWis3a2aVneCo9Uw1SFs mysecondemail@.com (ED25519)

If this is your SSH key for GitHub you can test the connection by running ssh -T git@github.com in the container. Does that work?
