markdown 如何在旧款MacBook上安装Docker，即MacBook Pro 2009？

Posted 2021-05-06

### Requirements

1. [Homebrew](https://brew.sh/)
2. [VirtualBox](https://www.virtualbox.org/wiki/Downloads)
3. [Heroku CLI](https://devcenter.heroku.com/articles/heroku-cli#download-and-install)

**Notes**

- Just install the VirtualBox. Don't have to do anything else.
- Installing Heroku CLI is optional. I'm a Heroku user. So, I want to leverage its [awesome bash auto-complete](https://blog.heroku.com/announcing-cli-autocomplete) feature which works with other commands as well.

### Install Docker

```
$ brew install docker docker-compose docker-machine
$ docker-machine create --driver virtualbox default
$ docker-machine env
$ eval $(docker-machine env default)

# [optional] enable the bash (tab) autocomplete
$ heroku update && heroku plugins:install autocomplete && heroku autocomplete
```
