## What is a Container { #what-is-a-container }

Containers (mainly Linux containers) are a very **lightweight** way to package applications including all their dependencies and necessary files while keeping them isolated from other containers (other applications or components) in the same system.

### GNU/Linux and macOS

```sh
docker-compose pull
docker-compose up
```

or

```sh
docker stack deploy --compose-file docker-compose.yaml minio
```

### Windows

```sh
docker-compose.exe pull

`PATH` 変数についての詳細は [環境変数](environment-variables.md#path環境変数){.internal-link target=_blank} を参照してください。

///

仮想環境を有効にすると、その仮想環境のパス `.venv/bin` （LinuxとmacOS）、あるいは `.venv\Scripts` （Windows）が `PATH` 変数に追加されます。

その環境を有効にする前の `PATH` 変数が次のようになっているとします。

//// tab | Linux, macOS

```plaintext
/usr/bin:/bin:/usr/sbin:/sbin
```

これは、OSが以下のディレクトリ中でプログラムを探すことを意味します：

* `/usr/bin`
* `/bin`
* `/usr/sbin`
