Chef/Modernize/ExecuteArchiveExtract

Cookstyle cops page

The Cookstyle cops department: Chef/Modernize

Use the archive_file resource built into Chef Infra Client 15+ instead of shelling out to tar or unzip. The resource extracts tar, tar.gz, tar.bz2, tar.xz, and zip archives, and it only runs when the archive is newer than what was already extracted, where the shelled out command re-extracts on every converge.

Examples

# bad
execute 'extract nginx' do
  command "tar xzf #{Chef::Config[:file_cache_path]}/nginx.tar.gz -C /opt/nginx"
end

execute 'unzip -o /tmp/app.zip -d /opt/app'

# good
archive_file 'extract nginx' do
  path "#{Chef::Config[:file_cache_path]}/nginx.tar.gz"
  destination '/opt/nginx'
end
