Problem connecting to Docker on Vagrant

Hello,

I'm trying to get the following working but to no avail.

I have a Docker setup running on Vagrant. Here's the Vagrantfile:

# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure(2) do |config|
  config.vm.box = "generic/ubuntu1804"
  config.vm.synced_folder "Volume/", "/volume"
  config.vm.network "private_network", ip: "192.168.10.101"
  config.vm.network "forwarded_port", guest: 2375, host: 2375, host_ip: "127.0.0.1"
  config.vm.provider "virtualbox" do |vb|
    vb.name = "Docker"
    vb.memory = 2048
    vb.cpus = 2
  end
  config.vm.provision "shell", inline: <<-SHELL
    add-apt-repository ppa:openjdk-r/ppa -y
    apt-get update
    echo "\n----- Installing Docker ------\n"
    wget -qO- https://get.docker.com/ | sh
    echo "\n----- Installing Java 8 & Maven ------\n"
    apt-get -y install openjdk-8-jdk
    update-alternatives --config java
    apt-get -y install maven
  SHELL
end

As you can see, I've forwarded port 2375.

Here's my docker-maven-plugin config in the project pom.xml.

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <version>1.2.0</version>
    <configuration>
        <imageName>${docker.image.name}:${docker.image.tag}</imageName>
        <dockerDirectory>${basedir}/target/dockerfile</dockerDirectory>
        <resources>
            <resource>
                <targetPath>/</targetPath>
                <directory>${project.build.directory}</directory>
                <include>${project.build.finalName}.jar</include>
            </resource>
        </resources>
    </configuration>
</plugin>

However when I launch the plugin's build, I get the following...

[INFO] Building image cwsp/configuration-server:b1

Any ideas ?

Many thanks,
