Googleが　謙虚、尊敬、信頼　を大事にしているとは驚きだった。
もっと技術的な思想があるかと思ったら、割とteamでの姿勢的なことなんだ。。
どこの開発現場でも一緒なんだなー

Mcrypt

This function is an extensive block algorithm such as CBC, OFB, CFB, ECB cipher modes DES, TripleDES, Blowfish (default), 3-WAY, SAFER-SK64, SAFER-SK128, TWOFISH, TEA, RC2 and GOST. Interface to the mcrypt library to support. In addition, it supports RC6 and IDEA, which are described as “not free”.

vagrant-omnibus

Check whether the Chef Client / Chef Solo exists in the instance or the expected version when starting Vagrant, and if not, automatically install it on the instance using Chef’s omnibus installer.

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

Vagrant.configure("2") do |config|
  config.vm.box = "<your_box_name_here>"
  config.vm.network :private_network, ip: "192.168.33.33"

  config.omnibus.chef_version = "11.4.0"

  config.vm.provision :chef_solo do |chef|
      chef.cookbooks_path = "./cookbooks"
      chef.add_recipe "apache"
   end
end

Berkshelf

Berkshelf is a tool to manage Chef cookbooks and their dependencies.

If you define a cookbook to be used for the definition file, you can eliminate depedencies automatically from the repository.

create zip directory with zip command

$ zip -r filename directoryname

[vagrant@localhost test]$ ls
test
[vagrant@localhost test]$ zip -r sample test
-bash: zip: コマンドが見つかりません

あれ、zipが入っていない？！

[vagrant@localhost test]$ sudo yum install zip
インストール:
zip.x86_64 0:3.0-1.el6_7.1

完了しました!

zipファイルを作ります。
[vagrant@localhost test]$ zip -r sample.zip test
adding: test/ (stored 0%)
[vagrant@localhost test]$ ls
sample.zip test

お！？

$ zip -e -v
->オプション
-e: –encrypt: 暗号化する

vagrant ssh-config

VagrantfileがあるディレクトリでOpenSSHの設定を行う。

>vagrant ssh-config
Host default
  HostName 127.0.0.1
  User vagrant
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile C:/Users/hoge/MyVagrant/Cent/.vagrant/machines/default/virtualbox/private_key
  IdentitiesOnly yes
  LogLevel FATAL

ん？なんじゃこりゃ。

取得できるファイルをssh.configに書き込み。
>vagrant ssh-config > ssh.config

>scp -F ssh.config vagrant@default:package-lock.json ./

まじこれ？
要するにvagrantにscp接続できたってこと？

うおおおおおおおおおおおお、全然追いつける気がしない。

OpenSSH

OpenSSH(Open Secure Shell) is software for using the SSH protocol, including an SSH server and an SSH client. OpenSSH is developed by the OpenBSD project and released under the BSD license. There are several other implementations of SSH, including the original SSH implementation SSH Tectia, but as of 2008, OpenSSH is the most used SSH implementation in the world.

Windows 10に OpenSSHが正式に組み込まれて使用できるとのこと。

SCP command

The “SCP” command is an abbreviation of “Secure Copy”, and it uses ssh to encrypt the communication between the remote host and the local host, and then copy and send the file.
