"knife container build" failing

[snayakie]

Hi,

I'm running the sample explained in the blog "https://www.getchef.com/blog/2014/07/15/release-chef-container-0-2-0-beta/" , with chef/centos-6 base image.

While doing "# knife container docker build chef/tnpfa-centos" , it goes fine for most of it but gives this error towards the end :

I'd appreciate if you can point on why this isn't working. Its the standard apache2 cookbook I used.

So undefined method []' for nil:NilClass typically means that you are referencing a node attribute that has not been defined. Can you provide me with the knife container docker init command you used as well as the contents of your first-boot.json? Also, what version of knife-container and chef-init are you using?

[snayakie]

yes, I am wondering if first-boot.json should have a 'service' rather than 'container_service'. But documentation page says 'container_service' so I've left it like this:

{ "run_list": [ "recipe[apt]", "recipe[apache2]" ], "container_service": { "apache2": { "command": "/usr/sbin/apache2 -k start" } } }

knife-container-docker-init command is :

knife container docker init chef/tnpfa-centos --run-list 'recipe[apt],recipe[apache2]' --include-credentials --berksfile --from chef/centos-6

[tduffield]

Aha! I found the bug - thank you for pointing this out. The issue is that chef-init is looking for new_resource.service_name when it should be looking for new_resource.name. This was an oversight on my part. That will be fixed in the next release of chef-init. For now the answer is to make sure that your node attribute value node['container_service'] uses the service_name rather than name.

{
   "container_service": {
      "httpd": {
         "command": "<command>"
      }
   }
}

Also, please be aware that /usr/sbin/apache2 -k is not the correct runit command for httpd running on centos. Please refer to http://smarden.org/runit/runscripts.html#apache2.

[snayakie]

Sorry, I don't understand what you mean about 'servicename' vs 'name' in first-boot.json. So what should the content be for my case?

Also, that 'runit' is new to me.... so what should be the command to start it on centos? thanks.

[tduffield]

{
   "container_service": {
      "httpd": {
         "command": "/usr/sbin/httpd -DFOREGROUND"
     }
  }
}

[snayakie]

That works. Thanks. Final question : how can I get get chef-container to work in a RHEL 6 base image? Is there any procedure you can give me for that, as there is no downloadable RHEL + chef-container image?

[tduffield]

You can see how I build our base images here: https://github.com/opscode/chef-container. You should be able to do something similar for any base image.

[snayakie]

Perfect, will take a look . Thanks again.
