Docker入門

Dockerの開発環境をローカル環境に構築する手順や、 Docker を使ったプログラムの記述方法や実行までをサンプルを使いながら順に学習していきます。

Docker oneliner集

oneliner

Dockerでよく使うOnelinerコマンド集

以下のコマンドは一度実行しておくことをお勧めする。

実行した後はshellのhistoryに登録されるので、Ctrl+Rで実行したいコマンドをさかのぼることで楽に実行できる。

Dockerのボリュームをまとめて消すコマンド

コンテナのボリュームをすべて消したかったらこのコマンドです。

docker rm -v $(docker ps -q)

一度実行した後はCtrl+Rで履歴を開きdocker rm -で再度実行できるはず。

サンプル実行結果

PS C:\Users\mineg\myworking> docker rm -v $(docker ps -q -f status=exited)
7435062f254c
6f16b42bdc4f
c29b1c16b4a7
ac59d05e5375
74b46930de22

Dockerのコンテナをすべてストップする

dockerのコンテナをストップするにはstopコマンドを使います。

docker stop $(docker ps -q)

こちらも一度実行した後はCtrl+Rで履歴を開きdocker stoぐらいで履歴に再度表示されるはず。

Dockerのイメージをすべて消す

docker rmi $(docker images -q)

一度実行した後はCtrl+Rで履歴を開きdocker rmi+Enterで実行できます

サンプル実行結果。

いつも実行しているコマンド

docker stop $(docker ps -q) | docker rmi $(docker images -q)

Dockerによるpythonワンライナー環境構築

Python

Dockerfileでpythonを実行したいとき

カレントディレクトリにあるmain.pyを実行したい

例えば以下のようにhelloworldと書かれたmain.pyがあるとき

$PSDefaultParameterValues['*:Encoding'] = 'utf8'
echo "print('hello world')" > main.py

以下のようにdockerのrunコマンドのオプションを駆使することでDockerfileもコンテナも残さずにコマンドを実行することができます

docker run --rm -v  ${pwd}:/app -w /app python:3-slim python main.py

一行で終わるpythonのコマンドをDockerで実行したい

main.pyを作ることすら面倒な場合もありますね。

その場合はpythonの-cオプションを使用することでpythonのファイルすら残さずにpythonのコードを実行することがができます。

docker run -it --rm python:3-slim python -c "print('hello world')"

Dockerエラー： this error may indicate that the docker daemon is not running

ErrorLog 
error during connect: this error may indicate that the docker daemon is not running: Get "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/json?all=1&filters=%7B%22label%22%3A%7B%22com.docker.compose.config-hash%22%3Atrue%2C%22com.docker.compose.project%3Ddocker-redmine%22%3Atrue%7D%7D": open //./pipe/docker_engine: The system cannot find the file specified.

対応

docker engineを起動しましょう。

  • もう一度再起動する
  • あるいは以下のdocker-composeファイルに書き換える
