travis CIでvagrantからS3にデプロイ

まず、vagrantでrubyが入っているか確認します。
[vagrant@localhost deploy]$ ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]

ruby 2.3.1ですね。travisをインストールします。

travis setupをする?
[vagrant@localhost deploy]$ travis setup s3
Shell completion not installed. Would you like to install it now? |y| y
Can’t figure out GitHub repo name. Ensure you’re in the repo directory, or specify the repo name via the -r option (e.g. travis -r /)

ん??
とりあえずtutorialを見てみよう。
https://docs.travis-ci.com/user/tutorial/

.travis.ymlをリポジトリに置くと書いてます。
>Add a .travis.yml file to your repository to tell Travis CI what to do. The following example specifies a Ruby project that should be built with Ruby 2.2 and the latest versions of JRuby.

deploy:
  provider: travis-s3
  access_key_id:
  secret_access_key:
    secure:
  endpoint:
  region: ap-northeast-1
  bucket: travisci-s3
  local-dir: /
  acl: public_read
  skip_cleanup: true
  on:
    repo: hpscript/travis-s3
  branches:
    only:
    - master

あれ、これ、githubにpushしたらaccess_keyとsecret_access_key漏れてしまうやんけ。
publicだと使えない??
