Unable to SSH Vagrant VM from other node

Vagrant
1

I have deployed my vagrant machine using the docker provider. I am able to access it from local.

My Vagrantfile

Vagrant.configure(2) do |config|
    ENV["LC_ALL"] = "en_US.UTF-8"

    config.vm.hostname = "dev-machine1"
    config.vm.provider "docker" do |d|
        d.image = "tknerr/baseimage-ubuntu:18.04"
        d.has_ssh = true
    end
    config.vm.network "forwarded_port", guest: 80, host: 8080, id: "nginx", auto_correct: true 
    config.ssh.insert_key = false
    config.ssh.forward_agent = true
    config.vm.provision "shell" do |s|  
        ssh_pub_key = File.readlines("/root/.ssh/vagrant1.pub").first.strip # /root/.ssh/vagrant-sample
        s.inline = <<-SHELL
            echo #{ssh_pub_key} >> /home/vagrant/.ssh/authorized_keys
            directory="/root/.ssh/"
            if [ ! -d "$directory" ]; then
                mkdir -p "$directory"
                echo "Directory '$directory' created."
            else
                echo "Directory '$directory' already exists."
            fi
            # sudo touch /root/.ssh/authorized_keys
            sudo echo #{ssh_pub_key} >> /root/.ssh/authorized_keys
        SHELL
    end            
    config.vm.provision "shell", path: ".provision/bootstrap.sh", privileged: false
end

I verified the public keys on the host machine as well as inside the container. They are correct. Able to SSH on port 2201 in local.

$ ssh -i vagrant1 vagrant@<my-other-node-where vagrant-vm-exists-ip> 
Permission denied (public key)

Ensure that the Vagrantfile includes proper SSH configuration. Here’s an example:

rubyCopy code

Vagrant.configure("2") do |config|
  config.vm.box = "your-box-name"
  config.vm.network "forwarded_port", guest: 22, host: 2222, id: "ssh"
end

2. Verify Port Forwarding:

Ensure that port forwarding branded products is set up correctly. The default port for SSH in Vagrant is 2222 on the host machine. Make sure you are trying to connect to the correct port.
