### 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しています。
tiryoh/ros-desktop-vncをベースにした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できます。
### Build 
```bash
> ./buildPEPPER.sh
```
上記の方法で実行する場合、マシンスペックによりますが、起動が遅い場合があります。
Reconstruction of a single layer image may take up to 20 minutes to merge multi-layer images.
### 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
時間がかかりますが、コンテナイメージがスタンバイ状態（"GET /api/health HTTP/1.0" が表示される状態）になったら、
別ターミナルを開いてコンテナIDを調べ、シングルレイヤー化した高速化したイメージpepper-lite.tazを作ります。
```
~/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 and make sure that only the current container ID, one, is displayed and after that press enter again.
-------------------------
Current running docker ontainer id is
-------------------------
28a1487ec5d2
-------------------------
When the string GET /api/health HTTP/1.0 is displayed, Please hit enter key
~/pepper$
```
### Import Rebuild Image and Run
高速化した、イメージpepper-lite.tazをインポートし、実行します。
```bash
~/pepper$ ./importPEPPERLITE.sh
~/pepper$ ./runPEPPERLITE.sh
```
### Open
ブラウザ経由
```bash
http://docker_ip:6080
```
### Ssh password is ubuntu
SSH経由
```bash
$ ssh ubuntu@docker_ip -p 2222
```
