JupyterLab（β）をjupyterの公式Dockerイメージを使ってサクッと試す

https://qiita.com/some-nyan/items/a4353cde6939e2dce351
を書いたあと、JupyterLabのβリリースがされていることに気づいてしまった。。。

JupyterLab

Jupyterの進化系、
Jupyterの機能に加えて、ファイルエクスプローラやコンソールも統合され
より統合開発環境として進歩している。

Jupyterの公式DockerイメージとJupyterLab

用途ごとに *-notebook というDockerイメージが公開されています。
JupyterLabのイメージないなぁと思ってREADME読んでたら、base-notebook
のREADMEにこんな一文が！

You can launch JupyterLab by setting JUPYTER_ENABLE_LAB:

やってみた

先日書いた、 docker-compose.yml に2行追加

version: '2.2'
services:
  jupyter:
    image: jupyter/datascience-notebook
    environment:
      JUPYTER_ENABLE_LAB: 1
    ports:
      - 8888:8888
    volumes:
      - ./:/home/jovyan/work
    command: start-notebook.sh --NotebookApp.token=''

すべての *-notebook は base-notebook から派生しているからいけるはず。。

$ docker-compose up

それっぽいこと言ってる！

アクセスしてみた

やったね！
