github 上Go项目使用Travis CI和Docker Hub实现持续集成

介绍

在本文中，我们将介绍如何使用Github，Travis-CI和Docker Hub创建一个简单的持续集成过程。

项目

这次使用的一个项目是自己写的一个爬虫小程序(github.com/Han-Ya-Jun/…)

.travis.yml

language: go
go:          # 语言版本号
  - "1.11.5"   # 默认使用最新版本,注意，需要 "1.10" 版本的时候必须表示为字符串形式，如果写成 1.10 则会使用 1.1 版本;x表示对应前缀的最新版本
services:
  - docker  #需要的docker环境


install:
  - make image-dev  #build

script:
  - echo "$DOCKER_PASSWORD" | docker login -u "$DOCKER_USERNAME" --password-stdin
  - make push-dev  # push

travis的配置(travis-ci.org)

打开项目ci开关

设置docker hub的用户和密码环境变量（push需要登录认证）

DOCKER_PASSWORD

DOCKER_USERNAME

提交项目代码触发ci
