update 2019.04.15

Windows10 : VirtualBox , Git , Vagrant

• Oracle VM VirtualBox : VirtualBox 6.0
• Git
  • Git Bash ターミナル使用
• Vagrant by HashiCorp

(Git Bash : Windows)

$ git --version
git version 2.21.0.windows.1

$ vagrant --version
Vagrant 2.2.4

Vagrant : CentOS7

(Git Bash : Windows)

$ cd /c/vagrant/centos7
$ vagrant init centos/7
$ vagrant up
$ vagrant ssh

(Git Bash : Vagrant - CentOS7)

$ cat /etc/centos-release

$ sudo yum -y update

Vagrantfile : private network (hostonly)

• host(windows10)から、アクセス用

config.vm.network "private_network", ip: "192.168.33.10"

Vagrantfile : synced folder

• VirtualBox Guest Additions インストール

$ vagrant plugin install vagrant-vbguest
$ vagrant vbguest
$ vagrant reload

• host(windows10)で、ファイル編集用

config.vm.synced_folder "./docker", "/docker", owner: "vagrant", group: "vagrant", type: "virtualbox", :mount_options => ['dmode=755', 'fmode=644']

※ DNS解決できない場合...

• ref. vagrantで構築した環境でDNS解決できていないかもな時

CentOS7 : docker , docker-compose

• ref. http://docs.docker.jp/engine/installation/linux/docker-ce/centos.html

hello_1  |
hello_1  | Hello from Docker!
hello_1  | This message shows that your installation appears to be working correctly.
hello_1  |
hello_1  | To generate this message, Docker took the following steps:
hello_1  |  1. The Docker client contacted the Docker daemon.
hello_1  |  2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
hello_1  |     (amd64)
hello_1  |  3. The Docker daemon created a new container from that image which runs the
hello_1  |     executable that produces the output you are currently reading.
hello_1  |  4. The Docker daemon streamed that output to the Docker client, which sent it
hello_1  |     to your terminal.
hello_1  |
hello_1  | To try something more ambitious, you can run an Ubuntu container with:
hello_1  |  $ docker run -it ubuntu bash
hello_1  |
hello_1  | Share images, automate workflows, and more with a free Docker ID:
