【Python×VScode×Docker】環境構築の方法

// For format details, see https://aka.ms/devcontainer.json. For config options, see the README at:
// https://github.com/microsoft/vscode-dev-containers/tree/v0.234.0/containers/docker-existing-docker-compose
// If you want to run as a non-root user in the container, see .devcontainer/docker-compose.yml.
{
	//"name": "SamplePython",//コンテナ表示名(今回はcomposeファイル内で指定しているため不要)

	// Update the 'dockerComposeFile' list if you have more compose files or use different names.
	// The .devcontainer/docker-compose.yml file contains any overrides you need/want to make.
	"dockerComposeFile": [
		"docker-compose.yml"
	],

	// The 'service' property is the name of the service for the container that VS Code should
	// use. Update this value and .devcontainer/docker-compose.yml to the real service name.
	"service": "app", //docker-composeから呼び出すサービス名

	// The optional 'workspaceFolder' property is the path VS Code should open by default when
	// connected. This is typically a file mount in .devcontainer/docker-compose.yml
	"workspaceFolder": "/app", //DockerfileのWORKDIRと同じ

	// Set *default* container specific settings.json values on container create.
	"settings": {},

	// Add the IDs of extensions you want installed when the container is created.
	"extensions": [
		"ms-python.python", //Pythonセット
		"aaron-bond.better-comments", //コメントに色をつけられる
		"kevinrose.vsc-python-indent", //Pythonの改行を自動で最適な場所へ
		"ms-ceintl.vscode-language-pack-ja", //日本語化
		"coenraads.bracket-pair-colorizer-2", //かっこ同士の色分け
		"oderwat.indent-rainbow" //段落の色分け
	]

	// Use 'forwardPorts' to make a list of ports inside the container available locally.
	// "forwardPorts": [],

	// Uncomment the next line if you want start specific services in your Docker Compose config.
	// "runServices": [],

	// Uncomment the next line if you want to keep your containers running after VS Code shuts down.
	// "shutdownAction": "none",

	// Uncomment the next line to run commands after the container is created - for example installing curl.
	// "postCreateCommand": "apt-get update && apt-get install -y curl",

	// Uncomment to connect as a non-root user if you've added one. See https://aka.ms/vscode-remote/containers/non-root.
	// "remoteUser": "vscode"
