changing PB IP and port using Chef about riak-chef-cookbook

[hectcastro]

Taking a look at this.

1. The documentation is up-to-date – pb_ip and pb_port are being deprecated in favor of the pb list with IP and port tuples (similar to the existing HTTP interface configuration method).
2. I believe you are correct here. We need to look and see if this can be done a different way.

On second look, I was able to use Vagrant's JSON attributes to override the default attributes of the Riak cookbook:

chef.json = {
  "riak" => {
    "args" => {
      "+S" => 1,
      "-name" => "[email protected]"
    },
    "config" => {
      "riak_api" => {
        "pb" => [["__tuple", "__string_33.33.33.10", 8888]]
      },
      "riak_control" => {
        "enabled" => (index == 1 ? true : false)
      }
    }
  }
}

And the corresponding app.config:

[
    {bitcask, [
        {data_root, "/var/lib/riak/bitcask"},
        {io_mode, erlang}
    ]},

What version of Chef are you running?

$ chef-client --version
Chef: 11.6.0

[kkalin78]

Hmm. I will try one more time. I use chef-solo 10.26

[hectcastro]

So after taking a closer look, Chef 11 overrides the attributes but 10.26 does not. For users on 10.x, we've suggested the following wrapper cookbook approach:

include_recipe "riak"

# Remove merged settings because override works differently on Chef 10
file "#{node['riak']['package']['config_dir']}/app.config" do
  content Proc.new {
    config = node['riak']['config'].to_hash
    # Deletes the unwanted attribute index
    config['riak_core']['pb'].delete_at(0)

    Eth::Config.new(config).pp
  }.call
  owner "root"
  mode 0644
  notifies :restart, "service[riak]"
end
