OpenNebula

Hello,

We are running CLI commands from a systemd service but the HOME is not set, we found issues with the following:

• oneuser
  

  eole@one-frontend:/$ unset HOME; oneuser list
  /usr/lib/one/ruby/cli/one_helper/oneuser_helper.rb:29:in `<class:OneUserHelper>': undefined method `+' for nil:NilClass (NoMethodError)
      from /usr/lib/one/ruby/cli/one_helper/oneuser_helper.rb:27:in `<top (required)>'
      from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
      from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
      from /usr/bin/oneuser:31:in `<main>'
  

• oneflow-template
  

  eole@one-frontend:/$ unset HOME; oneflow-template list
  /usr/lib/one/ruby/cloud/CloudClient.rb:58:in `<module:CloudClient>': undefined method `+' for nil:NilClass (NoMethodError)
      from /usr/lib/one/ruby/cloud/CloudClient.rb:50:in `<top (required)>'
      from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
      from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
      from /usr/lib/one/ruby/opennebula/oneflow_client.rb:18:in `<top (required)>'
      from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
      from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
      from /usr/bin/oneflow-template:31:in `<main>'
  

Other commands have a more explicit message:

eole@one-frontend:/$ onehost list
/usr/lib/one/ruby/opennebula/client.rb:130:in `initialize': ONE_AUTH file not present (RuntimeError)
    from /usr/lib/one/ruby/cli/one_helper.rb:412:in `new'
    from /usr/lib/one/ruby/cli/one_helper.rb:412:in `get_client'
    from /usr/lib/one/ruby/cli/one_helper.rb:470:in `set_client'
    from /usr/bin/onehost:43:in `block (2 levels) in <main>'
    from /usr/lib/one/ruby/cli/command_parser.rb:445:in `run'
    from /usr/lib/one/ruby/cli/command_parser.rb:76:in `initialize'
    from /usr/bin/onehost:36:in `new'
    from /usr/bin/onehost:36:in `<main>'

I found that all commands except oneuser and oneflow-template fallback to use /var/lib/one/.one/one_auth, which works when running as oneadmin.

Regards.

NB: I'm not sure between a bug or request.
