전인환 (treetory@gmail.com)

2. Vagrant 란?
● What is vagrant?

3. Usefulness of Vagrant
➔ For Developers
Say goodbye to "works on my machine"
bugs.
➔ For Operators
stop juggling SSH prompts to various
machines, and start using Vagrant to
bring sanity to your life.
➔ For Designers
No more bothering other developers to
help you fix your environment so you can
test designs.

4. Vagrant 도 일종의
협업도구라고 보면 됩니다.

5. Vagrant 설치
● Hypervisor (provider) 를 선택
● Vagrant downloads page 에서 Vagrant 다운
● 그리고 설치

6. Hypervisor 간의 충돌
➔ VirtualBox VS. KVM
echo ‘blacklist kvm-intel’ >>
/etc/modprobe.d/blacklist.conf
➔ VirtualBox VS. Hyper-V
Disable-WindowsOptionalFeature
-Online -FeatureName
Microsoft-Hyper-V-All
➔ Create the VM using 64-bit OS
enable the VT-D option in BIOS

7. Single Workflow - VagrantFile
● vagrant init

v.linked_clone = true if
Gem::Version.new(Vagrant::VERSION) >=
Gem::Version.new('1.8.0')
v.customize ["modifyvm", :id,
"--cpuexecutioncap", "50"]

v.cpus = 2
end

10. config.vm #3 : network
● Private or Public

end
Vagrant.configure("2") do |config|
config.vm.network "public_network", ip: "”,
netmask: "”, auto_config: "”,
use_dhcp_assigned_default_route: "”, bridge: "”,
nic_type: "”
end

11. config.vm #4 :
synced_folder
● Very convenient function
● Share between Host Machine and
Guest Machine
Vagrant.configure("2") do |config|
config.vm.synced_folder “/home”, “/dev”
end
→ Guest Machine
/vagrant

12. config.vm #5 :
provision
● When is occured the
provisioning?

puppet, salt and docker
● Once or Always or Never
Vagrant.configure("2") do |config|
config.vm.provision "shell", inline: "echo hello”, run:
"always”
end
Vagrant.configure("2") do |config|
config.vm.provision "bootstrap", type: "shell”, run:
"never” do |s|
s.inline = “echo hello”
end

● config.ssh.shell (string)
● config.ssh.sudo_command (string)
● config.ssh.username (string)
● config.ssh.verify_host_key (string, symbol)

15. 이렇게 씁니다.
➔ vagrant init
먼저 VagrantFile 을 생성합니다.
➔ vi VagrantFile
템플릿을 내 상황에 맞게 수정합니다.
➔ vagrant up
그리고 프로비저닝 합니다.
➔ vagrant halt
사용후엔 종료합니다.

16. 감사합니다.
부족한 발표 들어주셔서
정말 감사합니다.
