docker コマンドの新旧対比表

かなり以前 (おそらくバージョン v1.3 頃) から、docker のコマンドは「新しい体系が推奨」されています。 未だにインターネット上の情報は「古いコマンドベースのもの」が多く、私もつい「古いコマンド』を使ってしまいます… 今回は新旧コマンドの対比表をメモしておきます。 尚、公式のコマンドリファレンスは Reference / CLI reference / docker (base command) にあります。

検証環境

対象	バージョン
docker	26.1.0

docker container 系

旧コマンド	新コマンド	説明
docker run	docker container run	新規のコンテナを起動する
docker exec	docker container exec	コンテナ内でコマンドを実行する
docker ps	docker container ls	コンテナの一覧を表示する
docker start	docker container start	停止中のコンテナを起動する
docker stop	docker container stop	起動中のコンテナを停止する
-	docker container prune	停止中の全コンテナを削除する
docker rm	docker container rm	コンテナを削除する
docker stats	docker container stats	コンテナのリソース使用状況を表示する

docker image 系

旧コマンド	新コマンド	説明
docker pull	docker image pull	コンテナレジストリからイメージを取得する
docker rmi	docker image rm	イメージを削除する
docker inspect	docker image inspect	イメージの詳細情報を表示する
docker save	docker image save	tar 形式でイメージを保存する
docker load	docker image load	tar 形式のイメージを読み込む
docker build	docker image build	Dockerfile からイメージを作成する
