Vagrant環境に開発環境を引っ越し

Posted at

開発環境

docker for mac 環境で動作の遅さを感じるので、
今更ながらvagrantで開発環境を作ってみようと思いました。

やってみてdockerの動作が早くなってびっくりです。
自分の場合だと、vscodeのおかげで開発に支障がでないので、
結果的にやってよかったと思います。

遅いと悩んでいるのであれば、試してみると快適になるかもしれません。

vagrant 環境設定

$ vagrant init 
$ mkdir source

Vagrantfile の中身

# -*- mode: ruby -*-
# vi: set ft=ruby :

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.
Vagrant.configure("2") do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at
  # https://docs.vagrantup.com.

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://vagrantcloud.com/search.
  config.vm.box = "bento/ubuntu-20.04"

  # 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  # `vagrant box outdated`.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.
  # NOTE: This will enable public access to the opened port
  # config.vm.network "forwarded_port", guest: 80, host: 8080

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine and only allow access
  # via 127.0.0.1 to disable public access
  # config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"

  # 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"

  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is
  # the path on the guest to mount the folder. And the optional third
  # argument is a set of non-required options.
  config.vm.synced_folder "./source", "/home/vagrant/shareMacSource"

  # Provider-specific configuration so you can fine-tune various
  # backing providers for Vagrant. These expose provider-specific options.
  # Example for VirtualBox:
  #
  config.vm.provider "virtualbox" do |vb|
    vb.gui = false
    vb.memory = "8192"
    vb.cpus = 4
  end
  #
  # View the documentation for the provider you are using for more
  # information on available options.

  # Enable provisioning with a shell script. Additional provisioners such as
  # Ansible, Chef, Docker, Puppet and Salt are also available. Please see the
  # documentation for more information about their specific syntax and use.
  # config.vm.provision "shell", inline: <<-SHELL
  #   apt-get update
  #   apt-get install -y apache2
  # SHELL
end

vagrant で 8080 とかで動かす時、この設定をよしなに変更することで、
mac でも localhost:8080 で接続することができる。

  # config.vm.network "forwarded_port", guest: 80, host: 8080

vagrant ssh-config を実行して ssh/config に追記する内容を出力する

Host develop
  HostName 127.0.0.1
  User vagrant
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile < youre privater ssh-key path>
  IdentitiesOnly yes
  LogLevel FATAL

vagrant に ssh で接続

$ ssh develop
---
vagrant@vagrant:~$ sudo passwd vagrant
new password:
Retype new password:

※入力したパスワードは非表示

nano から vim に変更

$ sudo update-alternatives --set editor /usr/bin/vim.basic

Docker インストール

公式ドキュメントのコマンドをコピペする
Ubuntu 20.04へのDockerのインストールおよび使用方法 | DigitalOcean


$ sudo apt-get update
$ sudo apt install -y apt-transport-https ca-certificates curl software-properties-common

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

$ sudo apt update
$ apt-cache policy docker-ce

$ sudo apt install -y docker-ce

$ sudo systemctl status docker

$ sudo usermod -aG docker ${USER}

-- ここでsshを切断し、再度接続 --

$ id -nG
vagrant@vagrant:~$ id -nG
vagrant adm cdrom sudo dip plugdev lxd lpadmin sambashare docker

-- docker が追加されている ---

docker コマンドが実行できるか確認
$ docker run hello-world

ログインシェルを fish に変更

$ sudo apt-add-repository ppa:fish-shell/release-3
$ sudo apt-get update
$ sudo apt-get install -y fish



$ which fish
> /usr/bin/fish 

$ sudo vi /etc/shells
※ fish のパスが追加されていることを確認(追加されていない場合は追記)

デフォルトシェルの変更
$ chsh -s /usr/bin/fish 
Password:


fish プラグインをインストール

$ fisher install jethrokuan/z
$ fisher install jethrokuan/fzf
$ fisher install decors/fish-ghq

便利コマンドを追加

ディレクトリ構造

.config/fish
├── config.fish
└── functions
    ├── peco_change_history.fish
    └── peco_exploer_directory.fish
config.fish
### ショートカットを追加
# peco shortcut key
function fish_user_key_bindings

  # Bind for peco show history to Ctlr+h
    bind \ch peco_change_history

  # Bind for prco change directory to Ctrl+f
    bind \cf peco_exploer_directory

end

pecho_change_history.fish
function peco_change_history
  if test (count $argv) = 0
    set peco_flags --layout=bottom-up
  else
    set peco_flags --layout=bottom-up --query "$argv"
  end
history|peco $peco_flags|read foo
if [ $foo ]
    commandline $foo
  else
    commandline ''
  end
end

peco_exploer_directory.fish
function peco_exploer_directory
   set -l query (commandline)

  if test -n $query
    set peco_flags --query "$query"
  end

  z -l | peco $peco_flags | awk '{ print $2 }' | read recent
  if [ $recent ]
      cd $recent
      commandline -r ''
      commandline -f repaint
  end
end

ホームディレクトリで vagrant コマンドが実行できるようにする

※ vagrant を使わない想定なのでこれでOK
開発環境は develop に集約してそこで docker とか動かしたい


$ direnv edit .
export VAGRANT_CWD=<Vagrantfile があるディレクトリを指定>

# 環境変数の有効化
$ direnv allow 

# vagrant コマンドを指定し、path指定したvagrant を操作できればOK
$ vagrant status 
Current machine states:
default                   running (virtualbox)

まとめ

docker for mac が遅くネイティブレベルの早さを手に入れたいと思い、
思い切って vagrant に開発環境を作ってみました。
macしかできないことは普段やらないので、メインPCをLinuxにするか悩み中です。
