Could not generate xml when using supervisord

[albundy83]

Hello,

here the problem I encounter when I use supervisord :

[2015-02-11T08:59:36+01:00] ERROR: === could not generate xml for {"name"=>"XXXXXXXXX", "chef_environment"=>"int", "run_list"=>#<Chef::RunList:0x00000002bf58e0 @run_list_items=[#<Chef::RunList::RunListItem:0x00000002be13b8 @Version=nil, @type=:role, @name="base">, #<Chef::RunList::RunListItem:0x00000002be12f0 @Version=nil, @type=:role, @name="load_balancer">]>, "recipes"=>[], "roles"=>["base", "load_balancer"], "fqdn"=>"XXXXXXXXX", "hostname"=>"XXXXXXXXX", "kernel_machine"=>"x86_64", "kernel_os"=>"GNU/Linux", "platform"=>"debian", "platform_version"=>"7.8", "tags"=>[]}: undefined method unpack' for nil:NilClass [2015-02-11T08:59:36+01:00] ERROR: === could not generate xml for {"name"=>"XXXXXXXXX", "chef_environment"=>"int", "run_list"=>#<Chef::RunList:0x00000002be02b0 @run_list_items=[#<Chef::RunList::RunListItem:0x00000002ba4260 @version=nil, @type=:role, @name="base">, #<Chef::RunList::RunListItem:0x00000002ba40d0 @version=nil, @type=:role, @name="tomcat">, #<Chef::RunList::RunListItem:0x00000002ba4328 @version=nil, @type=:role, @name="backend">]>, "recipes"=>[], "roles"=>["base", "tomcat", "backend"], "fqdn"=>"XXXXXXXXX", "hostname"=>"XXXXXXXXX", "kernel_machine"=>"x86_64", "kernel_os"=>"GNU/Linux", "platform"=>"debian", "platform_version"=>"7.8", "tags"=>[]}: undefined methodunpack' for nil:NilClass

I have configured chef-rundeck like this in supervisord :
[program:chef-rundeck-test]
command=/usr/local/rvm/gems/ruby-2.2.0/wrappers/chef-rundeck -c /etc/chef/knife.rb -p 9981 --timeout 80
redirect_stderr=true
stdout_logfile=/var/log/chef-rundeck-int.log

(It works perfectly when I start in in command line...)

Thanks a lot for your help and your great tool.

And is it possible to run 2 or 3 chef-rundeck instances in // ?
Something like :
/usr/local/rvm/gems/ruby-2.2.0/wrappers/chef-rundeck -c /etc/chef/knife-1.rb -p 9980 --timeout 80
/usr/local/rvm/gems/ruby-2.2.0/wrappers/chef-rundeck -c /etc/chef/knife-2.rb -p 9981 --timeout 80

Happens to me too using upstart

@albundy83 what did you end up doing? This worked for me via upstart:

script
exec su - ops -c "chef-rundeck -o 0.0.0.0 -c /path/to/knife.rb -t 3600"
end script

esac

I just ran into this with runit and the problem turned out to be that chef-rundeck tries to get the username from the USER environment variable if you don't set it explicitly with -u. If USER is cleared or not set by the supervisor you get the above error unless you specify the user with -u.
