Vagrant: Forwarded Ports doesn't work

Question

I have a spring application which is compileable/runs on vagrant and listens to localhost:8080 (inside vagrant).

This is my Vagrantfile:

Vagrant.configure("2") do |config|
config.vm.box = "ubuntu/xenial64"
config.vm.network :forwarded_port, guest: 80, host: 9000, host_ip: "127.0.0.1"
config.vm.provision :shell, path: "bootstrap.sh"
end

Now I want to access my spring-application from the host machine via localhost:9000.

Anyway the forwarded_port line doesn't work and I really have no idea why?

What do I have to change in my Vagrantfile?

SOLUTION:

With the Vagrantfile below it works for me.

Vagrant.configure("2") do |config|
config.vm.box = "ubuntu/xenial64"
config.vm.network "private_network", ip: "192.168.33.10"
config.vm.provision :shell, path: "bootstrap.sh"

config.vm.provider "virtualbox" do |v|
        v.destroy_unused_network_interfaces = true
        v.memory = 2048
        v.cpus = 4
end
end

It doesn't work because the app is listening on localhost.

Make the app listen on a regular interface. You might also need to add guest_ip if it's not the Vagrant interface.

config.vm.network :forwarded_port, guest: 80, guest_ip: "xxx.xxx.xxx.xxx", host: 9000, host_ip: "127.0.0.1

can you be more specific? .. I am totally new to all this pseudo-server stuff – SteveOhio Apr 21 '17 at 05:39
I can't be more specific, because you are not. Localhost is, as its name suggests, for local connections only. – techraf Apr 21 '17 at 05:40
so I have to make the spring-app listening to the `guest_ip`? – SteveOhio Apr 21 '17 at 05:41
Maybe, depending on your understanding. In a common language: you need to bind it to a regular network interface, not localhost. – techraf Apr 21 '17 at 05:42
sorry, but what regular interface? can you give an example? – SteveOhio Apr 21 '17 at 05:43
No. I'm sorry, I'm not going to teach you how computer network interfaces work. – techraf Apr 21 '17 at 05:44
try `guest_ip: "127.0.0.1"` – Karl Pokus Sep 05 '20 at 20:06

If your spring app running in the VM is indeed listening to its local port 8080, and you want to access that app as http://localhost:9000/ from your host machine, then the line in your Vagrantfile should be:

config.vm.network :forwarded_port, guest: 8080, host: 9000

i.e. you have a typo specifying port 80 on the guest rather than 8080.

You probably don't need to specify any other parameters such as host_ip or guest_ip.
