How to get two vagrant boxes to talk to each other?

问题

Let's say I make two vagrant boxes, foo and bar:

$ mkdir -p foo bar
$ pushd foo; vagrant init hashicorp/precise32; vagrant up; popd
$ pushd bar; vagrant init hashicorp/precise32; vagrant up; popd

Now let's say I start an HTTP server on foo:

$ cd foo
$ vagrant ssh -c 'python -m SimpleHTTPServer 8080

My question is, how can I get bar to communicate (e.g. via curl) with foo?

$ cd bar
$ vagrant ssh -c 'curl http://????'

Although the question does not make it clear, I think this older question is asking:if the *same* development machine is running two vagrant instances, how can an app running onfoofetch data from a url onbar`.

If so, I ran into this recently for my two Rails apps(each running in a separate vagrant instance on the same development machine).

The two-part 'trick' if foo wants to fetch data from bar, is:

1) each Vagrant files needs a line:

config.vm.network :private_network, ip: PVT_NETWORK

where PVT_NETWORK is a local IP, is different for each Vagrant file, and probably needs to be in the same subnet. For example PVT_NETWORK might be 192.168.50.50 (foo) and 192.168.50.51 (bar)

2) foo accesses bar via the PVT_NETWORK IP address not the "real" IP you would use with a web browser.

In my Rails example, I also have each app running on a different port, so foo is on localhost:3000 and bar is on localhost:3001, so foo would access a url on bar via

http://192.168.50.51:3001/some_url

If the two servers are in the same network and no ACL between them (local boxes) they can communicate with each other after configuring the network.

configure the vagrant file:

# 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# `vagrant box outdated`.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

# 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"
