[chef] Re: Re: Using Chef to install Java (my first recipe)

troubleshoot tip

always look for Chef's pointer like on line 38 because Chef usually points out to you where is the problem, also check line 11 in your default.rb

38>>   tarball_url = node['java']['jdk']['7'][arch]['url']

your default recipe could look different - package has to be installed so something is missing in that code, then you only gave right to some directory, without creating it first

Change include_recipe "java::oracle" to be include_recipe "java::default"

Then, set on the node: node['java']['install_flavor'] = 'oracle'

I'm a Chef newbie and am struggling with writing a recipe to install Java (and eventually install Jenkins nodes and configure jobs).

my recipes/default.rb looks like:

package "git-core"
include_recipe "java::oracle"

directory '/jenkins' do
    user 'jenkins'
    group 'root'
    mode '0700'
end

my nodes/hostname.json file looks like:

{ 
    "java": {
        "jdk_version": "7",
        "java_home": "opt/java", 
        "oracle" : {
            "accept_oracle_download_terms": true
        }
    },
    "run_list":["recipe[main]"]
}

Here is my execution output:

Here are my questions:

1) I'm guessing that I shouldn't have to put these recipe settings in my nodes/hostname.json file. I tried putting them in the recipe (they will need to apply to all nodes), but couldn't get that to work.

2) I'm sure my java config is wrong, but I'm not sure how. the error is undefined method of nil onnode['java']['jdk']['7'][arch]['url']

The default.rb attributes for the java recipe has this in it, so I don't know why I would get the nil:

default['java']['jdk']['7']['x86_64']['url'] = 'http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-x64.tar.gz'

thanks for any thoughts!
