ruby - How do I deploy octopress 3 to a subdirectory within an existing gh-pages site? -

i using octopress 3, , when run jekyll build, generates correct set of files (which includes static files, see list of files below):

      $ cd _site :_site$ ls -a .               cname               assets              google2d8.html  index-alternative.html ..                            blog                increase-revenue.html       index.html 

note entire jekyll-generated blog safely stored within \blog\, how want it.

but once octopress deploy, overwrites entire folder (which overwrites existing static files), see listing below:

      $ cd _site :_site$ ls -a .       ..      gemfile     gemfile.lock          css     feed.xml    index.html  jekyll 

here _config.yml:

title: title email: some@email.com description: > # means ignore newlines until "baseurl:"      description baseurl: "/blog" # subpath of site, e.g. /blog url: "http://example.com" # base hostname & protocol site twitter_username: myusername  source: '../'  # build settings markdown: kramdown theme: minima 

this _deploy.yml

method: git                 # how want deploy? git, rsync or s3. site_dir: _site             # location of static site files. git_url: my_git_url  git_branch: gh-pages-2       # git branch static site files commited 

note: once remove following line _config.yml: source: '../', jekyll build generates deploy folder octopress deploy does.

given new octopress 3 , existing static site hosted on gh-pages branch, how deploy blog subdirectory of existing gh-pages site?

you're not setting root dir correctly.
