Vagrant環境下でDockerを動かす

Vagrant(Ubuntu18.04)を作成しつつDockerをインストールしておく
まずは、Vagrantファイルの作成。

$ vagrant init ubuntu/bionic64
$ vagrant up

次にVagrantファイルにDockerをインストールしておくよう、provisionを追加。

$ diff Vagrantfile-docker Vagrantfile-org 
32,33d31
<   config.vm.network "forwarded_port", guest: 80, host: 10800, host_ip: "127.0.0.1"
<   config.vm.network "forwarded_port", guest: 443, host:10443, host_ip: "127.0.0.1"
37c35
<   config.vm.network "private_network", ip: "192.168.33.10"
---
>   # config.vm.network "private_network", ip: "192.168.33.10"
48c46
<   config.vm.synced_folder "./data", "/home/vagrant/data"
---
>   # config.vm.synced_folder "../data", "/vagrant_data"
54c52
<   config.vm.provider "virtualbox" do |vb|
---
>   # config.vm.provider "virtualbox" do |vb|
59,60c57,58
<     vb.memory = "8196"
<   end
---
>   #   vb.memory = "1024"
>   # end
72d69
<   config.vm.provision "docker"

これでVagrantを起動するだけ。

 
$ vagrant up
