gh-pages-travis

CLI to deploy a folder to gh-pages branch of current repo as part of travis build

Usage

Install as a development dependency

npm install --save-dev gh-pages-travis

Add a script entry to package.json (npm puts the node_modules/.bin directory on the path when it runs scripts)

{
  "scripts": {
    "gh-pages-travis": "gh-pages-travis"
  }
}

Create your gh-pages branch and add the following .travis.yml to prevent travis from building it

branches:
  except:
    - gh-pages

Generate a deploy key for your Github repository

ssh-keygen -t rsa -C "your_email@example.com"

This will generate the id_rsa and id_rsa.pub files

Add id_rsa.pub as a deploy key for your Github repository

Install the travis cli client

gem install travis

Login the travis cli and encrypt the private key, id_rsa

travis login
travis encrypt-file id_rsa --add

This will add the decrypt command to recreate id_rsa in the current folder as a before_install script

NB. Make sure you delete the id_rsa and id_rsa.pub files and add the id_rsa.enc to the repository.

Lastly update your .travis.yml to configure the script and run it after a successful build

after_sucess:
  - npm run gh-pages-travis
env:
  global:
    - DEPLOY_BRANCH="master"
    - SOURCE_DIR="doc"
    - TARGET_BRANCH="gh-pages"
    - SSH_KEY="id_rsa"
    - GIT_NAME="travis"
    - GIT_EMAIL="deploy@travis-ci.org"

All the environment variables are optional but it's likely that 1 or more will need to be set.

• DEPLOY_BRANCH defaults to master. It ensures that the github pages are only deployed from builds of this branch.
• SOURCE_DIR defaults to doc. It is likely that this will need to be changed to the directory in which the actual site source is built.
• TARGET_BRANCH defaults to gh-pages. Typically this can be changed to master to deploy to the master branch of a xxxxx.github.io repository.
• SSH_KEY defaults to id_rsa. It would only need to be set if a different name was used for the SSH key to that documented above.
• GIT_NAME defaults to travis. This is the name that will be used for git commits, you probably want to change this.
• GIT_EMAIL defaults to deploy@travis-ci.org. This is the email that will be used for git commits, you probably want to change this.
