## <span style="color: #00ccff;">02. Vagrant 簡介</span>
1. Vagrant 由 HashiCorp 開發
:::info
**:bulb: Terraform 也是由 HashiCorp 開發**
* Terraform：**infrastructure as code** software which enables provisioning and adapting virtual infrastructure across all major cloud providers.
* The primary usage of Terraform is for managing remote resources in cloud providers such as AWS. Terraform is designed to be able to manage extremely large infrastructures that span multiple cloud providers. Vagrant is designed primarily for local development environments that use only a handful of virtual machines at most.
* Vagrant is for development environments. Terraform is for more general infrastructure management.
:::
2. 用於構建和管理虛擬機環境的工具。
3. 提供易於配置(configure)、可重現(reproducible)和可攜性(portable)的工作環境。
4. 支援 Shell 腳本、Chef 或 Puppet 等標準配置工具，可以在虛擬機上自動安裝和配置軟體。

The Bento boxes are [open source](https://github.com/chef/bento) and built for a number of providers including VMware, VirtualBox, and Parallels. There are a variety of operating systems and versions available.[color=#fa5252]
### 4-1 從既有的 Vagrantfile 啟動虛擬機
1. 切換至 .\docker-install 並執行 `vagrant up`
* row 18：配置 Private Key
* row 32：開始執行 shell 安裝 docker
```powershell=
PS C:\Users\User> cd D:\RCC-sharing\vagrant-demo\docker-install
PS D:\RCC-sharing\vagrant-demo\docker-install> vagrant up

==> dockerlab: Machine booted and ready!
(略)
==> dockerlab: Running provisioner: shell...
dockerlab: Running: inline script

(略)
```
2. 驗證虛擬機狀態 `vagrant status`
* row 4：虛擬機狀態為 running
```powershell=
PS D:\RCC-sharing\vagrant-demo\docker-install> vagrant status
Current machine states:
dockerlab running (virtualbox)
The VM is running. To stop this VM, you can run `vagrant halt` to
shut it down forcefully, or you can run `vagrant suspend` to simply
suspend the virtual machine. In either case, to restart it again,
simply run `vagrant up`.
```
### 4-2 進入虛擬機訪問 Guest OS
1. 登入方式-01：`vagrant ssh`
```powershell=
PS D:\RCC-sharing\vagrant-demo\docker-install> vagrant ssh

:::info
**:bulb: 無法透過 `ssh -i` 登入處理方式**
* 確認目錄 ~/.ssh 是否有先前產生的檔案 known_hosts ，刪除後就能成功透過密碼登入虛擬機
:::
3. 登入方式-03：`ssh -p [port] vagrant@127.0.0.1`
```powershell=
PS D:\RCC-sharing\vagrant-demo\docker-install> vagrant ssh-config
Host dockerlab
HostName 127.0.0.1
User vagrant

:::spoiler 調整 sshd_config，設定 PasswordAuthentication 的 Permission Policy
```bash=
vagrant@docker-lab:/etc/ssh$ sudo vim sshd_config
# To disable tunneled clear text passwords, change to no here!
PasswordAuthentication yes | no
#PermitEmptyPasswords no
vagrant@docker-lab:/etc/ssh$ sudo systemctl restart sshd
vagrant@docker-lab:/etc/ssh$ exit
logout
```
登入測試 Permission denied
```powershell=
PS D:\RCC-sharing\vagrant-demo\docker-install> ssh -p 2222 vagrant@127.0.0.1
vagrant@127.0.0.1: Permission denied (publickey).
```
:::
### 4-3 暫停或重啟虛擬機
1. 暫停虛擬機 `vagrant suspend`
```powershell=
PS D:\RCC-sharing\vagrant-demo\docker-install> vagrant suspend
==> dockerlab: Saving VM state and suspending execution...
```
2. 重啟虛擬機 `vagrant resume`
```powershell=
PS D:\RCC-sharing\vagrant-demo\docker-install> vagrant resume
==> dockerlab: Resuming suspended VM...
==> dockerlab: Booting VM...
==> dockerlab: Waiting for machine to boot. This may take a few minutes...
dockerlab: SSH address: 127.0.0.1:2222
dockerlab: SSH username: vagrant
dockerlab: SSH auth method: private key
==> dockerlab: Machine booted and ready!
==> dockerlab: Machine already provisioned. Run `vagrant provision` or use the `--provision`
==> dockerlab: flag to force provisioning. Provisioners marked to run always will still run.
```
### 4-4 停止並刪除虛擬機
加入 `-f` 選項強制刪除虛擬機 `vagrant destroy -f`
```powershell=
PS D:\RCC-sharing\vagrant-demo\docker-install> vagrant destroy -f
==> dockerlab: Forcing shutdown of VM...
==> dockerlab: Destroying VM and associated drives...
```
### 4-5 製作 Vagrantfile
透過 `vagrant init` 初始化一個新的 Vagrant 環境
```powershell=
PS C:\Users\User> cd D:\RCC-sharing\vagrant-demo\docker-install
PS D:\RCC-sharing\vagrant-demo\docker-install> vagrant box list
bento/ubuntu-18.04 (virtualbox, 202112.19.0)
bento/ubuntu-20.04 (virtualbox, 202112.19.0)
bento/ubuntu-20.04 (virtualbox, 202206.03.0)
generic/ubuntu1604 (virtualbox, 4.1.6)
generic/ubuntu1804 (virtualbox, 4.1.6)
generic/ubuntu2004 (virtualbox, 4.1.6)
ubuntu/focal64 (virtualbox, 20220825.0.0)
PS D:\RCC-sharing\vagrant-demo\docker-install> vagrant init bento/ubuntu-20.04 --box-version 202206.03.0
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.
```
本次所使用的 Vagrantfile
```ruby=
Vagrant.configure("2") do |config|
config.vm.box = "bento/ubuntu-20.04"
config.vm.box_version = "202206.03.0"
config.vm.hostname = 'docker-lab'
config.vm.define vm_name = 'dockerlab'
config.vm.provider "virtualbox" do |vb|
# Customize the amount of memory on the VM:
vb.cpus = 2
vb.memory = "2048"
end
# 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
# Uninstall old versions
sudo apt-get remove docker docker-engine docker.io containerd runc
# Install using the repository
sudo apt-get update
sudo apt-get -y install \
ca-certificates \
curl \
gnupg \
lsb-release
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \

sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y
apt-cache madison docker-ce
SHELL
end
```
## <span style="color: #00ccff;">05. Docker 簡易操作</span>
1. 驗證 Docker 已經透過 Vagrantfile 在啟動虛擬機後，使用 `inline: <<-SHELL` 完成安裝
```bash=
vagrant@docker-lab:~$ sudo docker version
Client: Docker Engine - Community

GitCommit: v1.1.4-0-g5fd4c4d
docker-init:

```
2. 運行 Container `docker run`
下載測試映像檔 (hello-world) 並在 Container 中運行，print 出訊息後退出（Exited） Container。
```bash=
vagrant@docker-lab:~$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
2db29710123e: Pull complete
Digest: sha256:7d246653d0511db2a6b2e0436cfd0e52ac8c066000264b3ce63331ac66dca625
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:
https://hub.docker.com/
For more examples and ideas, visit:
https://docs.docker.com/get-started/
```
3. 列出容器
* 運行中 `docker ps`
* 所有容器 (運行中－Up & 非運行中－Exited） `docker ps -a`
```bash=
vagrant@docker-lab:~$ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
vagrant@docker-lab:~$ sudo docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
6c800baf4a7d hello-world "/hello" 48 seconds ago Exited (0) 46 seconds ago clever_keldysh
```
4. 安裝 NGINX 網頁伺服器
* 由於執行完 NGINX 會退出 Container，因此可以加入 Option `-d` 在背景繼續執行
* `-p 80:80` 將 Guest OS 的 80 port 路由到 Container 的 80 port
```bash=
vagrant@docker-lab:~$ sudo docker run -p 80:80 nginx
Unable to find image 'nginx:latest' locally
