[chef] Using not_if in bash block still causes file to be downloaded

[Arthur Kalmenson < >]

Hello everyone,

I'm writing a recipe to install hubot using the bash resource and using the not_if constraint to avoid reinstalling each time chef-client runs. While the reinstall does not happen, I'm finding that the hubot file continues to be downloaded with wget. Therefore, the /tmp dir is filling up with hubot tar files. Is there a reason why parts of the bash block execute and others don't?

The recipe looks as follows:

...

install_dir = "#{node['hubot']['install_dir']}"

install_dir_parent = "#{node['hubot']['install_dir_parent']}"

version = "#{node['hubot']['version']}"

...

bash "install hubot" do

  user hubot_user

  group hubot_group

  environment ({'HOME' => "#{install_dir}" })

  cwd install_dir_parent

  code <<-EOH

    wget -P /tmp https://github.com/downloads/github/hubot/hubot-#{version}.tar.gz && \

    tar xzf /tmp/hubot-#{version}.tar.gz && \

    cd hubot && \

    npm install

  EOH

  not_if "#{install_dir}/bin/hubot -v 2>&1 | grep '#{version}'"

end

The full recipe file is here: https://gist.github.com/1730793. Thank you in advance for any help.

All the best,
