Vagrantfile with docker provider portfoward error - mysql

Question

I want to set up an environment with Vagrant. I defined 2 mysql in Vagrantfile, one for development, and one for integration tests. To differentiate these 2 instance I want to expose different ports.
# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure("2") do |config|
config.vm.network "private_network", ip: "192.168.100.138", nic_type: "82545EM"
config.vm.define "mysql" do |m|
config.vm.provider "docker" do |d|
d.name = "mysql"
d.image = "mysql:8"
d.ports = ["3306:3306"]
d.env = {"MYSQL_DATABASE" => "development", "MYSQL_ROOT_PASSWORD" => "root"}
d.remains_running = true
end
end
config.vm.define "mysql-integration-test" do |mit|
config.vm.provider "docker" do |d|
d.name = "mysql-integration-test"
d.image = "mysql:8"
d.ports = ["3406:3306"]
d.env = {"MYSQL_DATABASE" => "development-it", "MYSQL_ROOT_PASSWORD" => "root"}
d.remains_running = true
end
end
end
The problem is when I started it I got an error than the port is already in use:

An error occurred while executing multiple actions in parallel.
Any errors that occurred are shown below.
An error occurred while executing the action on the 'mysql-integration-test'
machine. Please handle this error then try again:
Vagrant cannot forward the specified ports on this VM, since they
would collide with some other application that is already listening
on these ports. The forwarded port to 3406 is already in use
on the host machine.
To fix this, modify your current project's Vagrantfile to use another
port. Example, where '1234' would be replaced by a unique host port:
config.vm.network :forwarded_port, guest: 3306, host: 1234
Sometimes, Vagrant will attempt to auto-correct this for you. In this
case, Vagrant was unable to. This is usually because the guest machine
is in a state which doesn't allow modifying port forwarding. You could
try 'vagrant reload' (equivalent of running a halt followed by an up)
so vagrant can attempt to auto-correct this upon booting. Be warned
that any unsaved work might be lost.
