I planned to test a Ruby on Rails project using vagrant in this box: https://atlas.hashicorp.com/nickcharlton/boxes/ruby-box.
The goal is to view the application in the host's browser.
Firstly, I have updated my virtualbox to 4.3.26 and my vagrant.
By following http://docs.vagrantup.com/v2/networking/basic_usage.html, I tried
config.vm.network "forwarded_port", guest: 3000, host: 3000
and
config.vm.network "private_network", ip: "192.168.33.10.
Actually, I can ping "192.168.33.10" from the host's terminal. But in the browser, I cannot reach the guest from localhost:3000 or 127.0.0.1:3000 or 192.168.33.10 or other url combinations.
The rails application should be working fine inside the guest because nothing went wrong from the bundle install process to rails s.
I can always boot the virtual machine and log in through ssh, however, I cannot get access to the application in either Firefox or Safari. That is when I noticed the endless Warning: Remote connection disconnect. Retrying...
Honestly I do not understand why after some repeated messages there would come ==> default: Machine booted and ready! and vagrant ssh would work just fine even in this situation.
I have tried a lot of ways to solve this problem.
I've tried adding "vb.gui = true" in VagrantFile, but it did not work out.
I've tried changing my DNS, and I've tried disconnecting my wifi, but they did not work out.
The Vagrantfile is like the following:
# -*- mode: ruby -*-
# vi: set ft=ruby :
# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.
Vagrant.configure(2) do |config|
# The most common configuration options are documented and commented below.
# For a complete reference, please see the online documentation at
# https://docs.vagrantup.com.
# Every Vagrant development environment requires a box. You can search for
# boxes at https://atlas.hashicorp.com/search.
config.vm.box = "nickcharlton/ruby-box"
# Disable automatic box update checking. If you disable this, then
# boxes will only be checked for updates when the user runs
# `vagrant box outdated`. This is not recommended.
# config.vm.box_check_update = false
# Create a forwarded port mapping which allows access to a specific port
# within the machine from a port on the host machine. In the example below,
# accessing "localhost:8080" will access port 80 on the guest machine.
# config.vm.network "forwarded_port", guest: 80, host: 8080
config.vm.network "forwarded_port", guest: 3000, host: 3000
# Create a private network, which allows host-only access to the machine
# using a specific IP.
# config.vm.network "private_network", ip: "192.168.33.10"
# Create a public network, which generally matched to bridged network.
# Bridged networks make the machine appear as another physical device on
# your network.
# config.vm.network "public_network"
# Share an additional folder to the guest VM. The first argument is
# the path on the host to the actual folder. The second argument is
# the path on the guest to mount the folder. And the optional third
# argument is a set of non-required options.
# config.vm.synced_folder "../data", "/vagrant_data"
# Provider-specific configuration so you can fine-tune various
# backing providers for Vagrant. These expose provider-specific options.
# Example for VirtualBox:
#
config.vm.provider "virtualbox" do |vb|
# # Display the VirtualBox GUI when booting the machine
vb.gui = true
#
# # Customize the amount of memory on the VM:
# vb.memory = "1024"
end
#
# View the documentation for the provider you are using for more
# information on available options.
# Define a Vagrant Push strategy for pushing to Atlas. Other push strategies
# such as FTP and Heroku are also available. See the documentation at
# https://docs.vagrantup.com/v2/push/atlas.html for more information.
# config.push.define "atlas" do |push|
# push.app = "YOUR_ATLAS_USERNAME/YOUR_APPLICATION_NAME"
# end
# Enable provisioning with a shell script. Additional provisioners such as
# Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the
# documentation for more information about their specific syntax and use.
# config.vm.provision "shell", inline: <<-SHELL
# sudo apt-get update
# sudo apt-get install -y apache2
# SHELL
end
