そして、自分の用途を考えると、何より色々試せるサンドボックス環境が欲しかったのだ。
ならば作ろうじゃないか Docker で！
自分がよく作るだろう環境を image 化する
という事で、おもむろに Ubuntu イメージからコンテナを作成する。

初っ端は更新から。
そしたら、デフォルトパッケージで nodejs と npm をインストールする。
ただしこの時点では node コマンドは使えなくて nodejs コマンドというクソっぷり。

ここで、npm を使って n コマンドをインストールする。

あとは wget なり curl なりをインストールして、n stable で最新安定板の node を入れてしまう。

しっかしデフォルトだと nodejs バージョンが古いものである。
まずはこれで、nodejs 用のコンテナができたわけだ。
後はイメージ化しておくと、コンテナ作成が楽でいい

後は使いたいときに使えるはずだ。
まずはその検証のために元を削除してみる。

そしたらイメージから起動する。
XXXXXXXX:~ azalea$ docker run -it nodejs9-sandbox
root@6cfb7120e148:/#
ひゃっはー。
そして関連コンテナを全て docker rm で削除した後

docker image rm イメージ名 でイメージ削除までいける事がわかった。
