Get the required software for Linux or macOS预计阅读时间: 2 分钟
This page explains how to get the software you need to use a Linux or macOS machine for Docker development. Before you begin contributing you must have:
- a GitHub account
You’ll notice that
go, the language that Docker is written in, is not listed.
That’s because you don’t need it installed; Docker’s development environment
provides it for you. You’ll learn more about the development environment later.
Task 1. Get a GitHub account
To contribute to the Docker project, you will need a GitHub account. A free account is fine. All the Docker project repositories are public and visible to everyone.
You should also have some experience using both the GitHub application and
on the command line.
Task 2. Install git
git on your local system. You can check if
git is on already on your
system and properly installed with the following command:
$ git --version
This documentation is written using
git version 2.2.2. Your version may be
different depending on your OS.
Task 3. Install make
make. You can check if
make is on your system with the following
$ make -v
This documentation is written using GNU Make 3.81. Your version may be different depending on your OS.
Task 4. Install or upgrade Docker
If you haven’t already, install the Docker software using the instructions for your operating system. If you have an existing installation, check your version and make sure you have the latest Docker.
To check if
docker is already installed on Linux:
docker --version Docker version 1.11.0, build 4dc5990
On macOS or Windows, you should have installed Docker Toolbox which includes Docker. You’ll need to verify both Docker Machine and Docker. This documentation was written on macOS using the following versions.
$ docker-machine --version docker-machine version 0.7.0, build a650a40 $ docker --version Docker version 1.11.0, build 4dc5990
Tip for Linux users
This guide assumes you have added your user to the
docker group on your system.
To check, list the group’s contents:
$ getent group docker docker:x:999:ubuntu
If the command returns no matches, you have two choices. You can preface this
docker commands with
sudo as you work. Alternatively, you can add
your user to the
docker group as follows:
$ sudo usermod -aG docker ubuntu
You must log out and log back in for this modification to take effect.
