What is Travis CI?

Travis CI is an online hosted CI service. Using Travis for continuous integration doesn’t require setting up your own server. Most importantly, it’s free for open source projects. If company uses gitlab, it also provides corresponding continuous integration services. Won’t elaborate here.

Travis CI Configuration File

Travis requires project root directory must have a .travis.yml file.

When your repository has commits, travis will automatically execute the behaviors you configured below.

.travis.yml

Below is my blog deployment configuration, also my project’s .travis.yml file content.

hugo

This is my hugo deployment configuration, for reference only

language: node_js
node_js: 10.13.0
install:
  - wget https://github.com/gohugoio/hugo/releases/download/v0.51/hugo_0.51_Linux-64bit.deb
  - sudo dpkg -i hugo*.deb

  - rm -rf container/*
  - cp -r public/* container
  - cd container
  - git add .
  - git commit -m 'Travis upate blog'
  - git push -u origin gh-pages -f

Hexo

This is my hexo deployment configuration, for reference only.

This is if you already use hexo-deployer-git configuration, of course I also recommend using this plugin, because it’s really convenient.

In the end we just need to use sed command to replace publish address in _config.yml file, can publish to specified repository without username password.

language: node_js
node_js: 10.13.0
before_script:
  - git config user.name "Fan"
  - git config user.email "your-email"
  - sed -i'' "s~https://github.com/Num142857/alili.tech.git~https://${ACCESS_TOKEN}@github.com/Num142857/alili.tech.git~" _config.yml
script:
  - hexo clean
  - hexo g
  - hexo d
