Connecting to git remote from Laravel devcontainer on VSC on windows

Question

I'm using a devcontainer in Visaul Studio Code on Windows. I built this devcontainer with the laravel sail helper. It runs on Docker desktop and WSL2.

This is the devcontainer json:

// https://aka.ms/devcontainer.json
{
    "name": "Existing Docker Compose (Extend)",
    "dockerComposeFile": [
        "../docker-compose.yml"
    ],
    "service": "laravel.test",
    "workspaceFolder": "/var/www/html",
    "settings": {},
    "extensions": [
        // "mikestead.dotenv",
        // "amiralizadeh9480.laravel-extra-intellisense",
        // "ryannaddy.laravel-artisan",
        // "onecentlin.laravel5-snippets",
        // "onecentlin.laravel-blade"
    ],
    "remoteUser": "sail",
    // "forwardPorts": [],
    // "runServices": [],
    // "postCreateCommand": "apt-get update && apt-get install -y curl",
    // "shutdownAction": "none",
}

And this is the docker composer file:

version: '3'
services:
    laravel.test:
        build:
            context: ./docker/8.1

        environment:

It's been working really well for working locally and pushing to my github repo.

But now I need to make a push to the production site.

So I tried

git remote add namecheap xx.xx.xx.xx:xxxx/home/user
git push namecheap dev


Unable to negotiate with xx.xx.xx.xx port xxxx: no matching host key type found. Their offer: ssh-rsa,ssh-dss
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

So I tried a few things which didn't work. Could someone kindly explain HOW I could add a ssh key to this devcontainer or forward the agent? Bear in mind that all the basic linux tools are missing. I don't even have vim or sudo inside this container. And have no idea how to add them. And do not know the SU password.

Answer 1

I gave up on this approach and instead called a git pull from the production site, after figuring out how to access the terminal
