Udemyがバーゲンをしていることに気づいたため、日本のゴールデンウィーク期間中は「[【ゼロから始めるデータ分析】 ビジネスケースで学ぶPythonデータサイエンス入門](https://www.udemy.com/course/optworks_1/)」でお勉強をしています。まだ終わっていません。。
|
||||||
|
|
||||||
|
この講座は`Jupyter`を用いてデータ分析を進める形でしたので、お家Kubernetes上に`Jupyter`を稼働させることとしました。

## JupyterのDockerイメージを探す
|
||||||
|
[JupyterのDockerイメージまとめ - Qiita](https://qiita.com/kshigeru/items/ea174d6bcacc474f2a51)でまとめられています。今回は、`datascience-notebook`を使うことにしました。
|
||||||
|
|
||||||
|
## JupyterのDockerイメージに日本語フォントを導入する
|
||||||
|
[Jupyterのmatplotlibを使用する際の日本語豆腐を解決 - Qiita](https://qiita.com/Gvling/items/29516eebccf527e7be5d)を参考にして、日本語フォントを導入します:
|
||||||
|
|
||||||
|
```docker
|
||||||
|
FROM jupyter/datascience-notebook
|
||||||
|
|
||||||
|
COPY ./ipag.ttf /opt/conda/lib/python3.7/site-packages/matplotlib/mpl-data/fonts/ttf/ipag.ttf
|
||||||
|
|
||||||
|
RUN echo "font.family : IPAGothic" >> /opt/conda/lib/python3.7/site-packages/matplotlib/mpl-data/matplotlibr
|
||||||
|
c
|
||||||
|
|
||||||
|
# Delete font cache
|
||||||
|
RUN rm -r ./.cache
|
||||||
|
```
|
||||||
|
|
||||||
|
## Kubernetesの設定
|
||||||
|
Kubernetesの設定をまとめます。
|
||||||
|
|
||||||
|
### Persistent Volume
|
||||||
|
Persistent Volumeはお家NASからNFSで領域を確保しています。
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: v1
|
||||||
|
kind: PersistentVolume
|
||||||
|
metadata:
|
||||||
|
name: nfs-jupyter-work
|
||||||
|
namespace: jupyter
|
||||||
|
labels:
|
||||||
|
name: nfs-jupyter-work
|
||||||
|
annotations:
|
||||||
|
volume.beta.kubernetes.io/storage-class: "slow"
|
||||||
|

|
||||||
|

||||||
|

|
||||||

|
||||||
|
apiVersion: v1
|
||||||
|

|
||||||
|
metadata:
|
||||||
|

|
||||||
|

|
||||||
|

|
||||||
|

||||||

|
||||||
|

|
||||||

|
||||||
|
persistentVolumeReclaimPolicy: Retain
|
||||||
|

|
||||||
|

|
||||||
|

|
||||||
|

|
||||||
|
```
|
||||||
|
|
||||||
|
### Persistent Volume Claim
|
||||||
|
確保したPersistent Volumeから、領域を確保します。
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: v1
|
||||||
|
kind: PersistentVolumeClaim
|
||||||
|
metadata:
|
||||||
|
name: jupyter-claim-work
|
||||||
|
namespace: jupyter
|
||||||
|
annotations:
|
||||||
|
volume.beta.kubernetes.io/storage-class: "slow"
|
||||||
|
spec:
|
||||||
|
accessModes:
|
||||||
|
- ReadWriteMany
|
||||||
|
resources:
|
||||||
|
requests:
|
||||||
|
storage: 25Gi
|
||||||
|
selector:
|
||||||
|
matchLabels:
|
||||||
|
name: nfs-jupyter-work
|
||||||
|
---
|
||||||
|
apiVersion: v1
|
||||||
|
kind: PersistentVolumeClaim
|
||||||
|
metadata:
|
||||||
|
name: jupyter-claim-config
|
||||||
|

|
||||||
|

|
||||||
|
volume.beta.kubernetes.io/storage-class: "slow"
|
||||||
|
spec:
|
||||||
|
accessModes:
|
||||||
|
- ReadWriteMany
|
||||||
|
resources:
|
||||||
|
requests:
|
||||||
|
storage: 25Gi
|
||||||
|
selector:
|
||||||
|
matchLabels:
|
||||||
|
name: nfs-jupyter-config
|
||||||
|
```
|
||||||
|
|
||||||
|
### Deployment
|
||||||
|
Deploymentの設定で、`Jupyter`のコンテナをデプロイします。レプリカの数は1個にしています。おそらく複数コンテナを起動しても、ステートレスに接続できないと考えたためです。
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: apps/v1
|
||||||
|
kind: Deployment
|
||||||
|
metadata:
|
||||||
|
name: jupyter
|
||||||
|

|
||||||
|

|
||||||
|

|
||||||
|
spec:
|
||||||
|

|
||||||
|

|
||||||
|

|
||||||
|

|
||||||
|

|
||||||

|
||||||
|

|
||||||
|
- containerPort: 8888
|
||||||
|

|
||||||

|
||||||

|
||||||

|
||||||

|
||||||
|

|
||||||
|

|
||||||
|
volumeMounts:
|
||||||
|
- mountPath: /home/jovyan/work
|
||||||
|

|
||||||
|
readOnly: false
|
||||||
|
- mountPath: /home/jovyan/.jupyter
|
||||||
|

|
||||||
|
readOnly: false
|
||||||
|
volumes:
|
||||||
|
- name: docker-jupyter-work
|
||||||
|
persistentVolumeClaim:
|
||||||
|
claimName: jupyter-claim-work
|
||||||
|
- name: docker-jupyter-config
|
||||||
|
persistentVolumeClaim:
|
||||||
|
claimName: jupyter-claim-config
|
||||||
|
```
|
||||||
|
|
||||||
|
### serviceの設定
|
||||||
|
serviceの設定は以下になります。プライベートIPアドレスの`192.168.10.210/24`でアクセスできるようにしています。ポート番号は80にしました。
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: v1
|
||||||
|
kind: Service
|
||||||
|
metadata:
|
||||||
|
name: jupyter
|
||||||
|
namespace: jupyter
|
||||||
|
spec:
|
||||||
|
ports:
|
||||||
|
- name: http
|
||||||
|
port: 80
|
||||||
|
protocol: TCP
|
||||||
|
targetPort: 8888
|
||||||
|
selector:
|
||||||
|
app: jupyter
|
||||||
|
type: LoadBalancer
|
||||||
|
loadBalancerIP: 192.168.10.210
|
||||||
|
```
|
||||||
|
|
||||||
|
## 動作確認
|
||||||
|
自宅ネットワークにいる状態でアクセスしたら、無事に接続できました。
