### ROSでペッパーを動かすためのDockerイメージ

PepperのIPは、192.168.100.3で同じネットワーク内にこのDockerファイルを動かすサーバがある設定を仮定。
tiryoh/ros-desktop-vncをベースとしたDockerイメージを採用しています。
このイメージは、novncを採用しているため、ブラウザ経由と、ssh経由の両方からアクセス可能。
### Build 
```bash
> ./buildPEPPER.sh
```
最初のビルトで実行する場合、マシンスペックによるが、起動に時間がかかる。
これは、Dockerファイルは、マルチレイヤーでイメージが構成されてるためである。
シングルレイヤーにするため、一度実行し、メモリに展開した状態で、再度キャプチャーし
シングルレイヤーのイメージを作る。
### Run Build Image
```bash
~/pepper$ ./runPEPPER.sh
* enable custom user: ubuntu
useradd: user 'ubuntu' already exists
  set default password to "ubuntu"
Please execute -> sudo apt install ros-kinetic-peper-meshes

### Export Image and Capture Rebuild Image
マルチレイヤ―イメージをメモリ展開し、コンテナがスタンバイ状態（"GET /api/health HTTP/1.0" が表示される状態）になってから、
別ターミナルを開いてコンテナIDを調べる。コンテナIDを元に、docker イメージをキャプチャーし、シングルレイヤー化
（起動の高速化とイメージサイズの圧縮に効果あり）したイメージpepper-lite.tazを作る。
```
~/pepper$ ./exportPEPPER.sh
Open a new terminal and run . /runPEPPER.sh and wait until you see GET /api/health HTTP/1.0. Press enter key.
-------------------------
Current running docker ontainer id is
-------------------------
28a1487ec5d2
-------------------------
Make sure that only one container ID is running and after that press enter key to capture single layered container image to pepper-lite.taz.
~/pepper$
```
### Import Captured Image and Run
高速化した、イメージpepper-lite.tazをインポートし、実行する。
```bash
~/pepper$ ./importPEPPERLITE.sh
~/pepper$ ./runPEPPERLITE.sh
```
### Open
ブラウザ経由
```bash
http://docker_ip:6080
http://localhost:6080
```
### Ssh password is ubuntu
SSH経由
```bash
$ ssh ubuntu@docker_ip -p 2222
```
