Chef Solo入門

More than 1 year has passed since last update.

はじめに

Chefの勉強をしようと思ったのですが、ネットの情報が古かったり、参考書の情報が古かったりでどハマりしたので備忘録にこの記事を書こうと思いました。

環境構築基礎編

Vagrantで仮想環境を構築

ホストOS:terminal
$ vagrant init centos/7
実行結果
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.
ホストOS:terminal
$ vagrant up

    default: This is not an error message; everything may continue to work properly,
    default: in which case you may ignore this message.

SSH設定

ホストOS:terminal
$ vagrant ssh-config --host {host name} >> ~/.ssh/config

上記の設定を行うことでssh {host name}でログインが可能になります。

プライベートネットワーク設定

config.vm.network "private_network", ip: "192.168.33.10"のコメントアウトを外す

Vagrantfile
# -*- 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 = "centos/7"

  # 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  # `vagrant box outdated`.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 "../data", "/vagrant_data"

  # 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|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
  #   vb.memory = "1024"
  # 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
  # Puppet, Chef, Ansible, Salt, and Docker 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

You are installing an omnibus package without a version pin.  If you are installing
on production servers via an automated process this is DANGEROUS and you will
be upgraded without warning on new releases, even to new major releases.
Letting the version float is only appropriate in desktop, test, development or

最後に

コマンドが新しくなっていたり、Versionの兼ね合いとかにだいぶ悩まされました。
ところどころ納得いかないところ(Warningがでてたり)があります、詳しい方がいらっしゃいましたらご指摘いただけると幸いです。
