FreeBSD and chef-client - a part II (of sorts)

Finally changed chef-client with an updated recipe to support FreeBSD.

Under the chef-repo/chef-client directory, I added the following files:

./templates/freebsd/rc.d/chef-client.erb
./templates/freebsd/rc.conf.d/chef.erb

And updated:

./recipes/service.rb

The locations corresponds to the directory location under the default #{conf} directory, (which is apparently /etc) The templates are .erb files that corresponds to the configuration files on the server.

chef-client.erb:

[rilindo@chef chef-client]$ cat ./templates/freebsd/rc.d/chef-client.erb
#!/bin/sh

# PROVIDE: chef
# REQUIRE: LOGIN
# KEYWORD: nojail shutdown

. /etc/rc.subr

name="chef"
rcvar=`set_rcvar`
stop_cmd="chef_stop"
command="/usr/local/bin/${name}-client"
command_args="-i -s -d -L /var/log/chef/client.log -c /etc/chef/client.rb -P /var/run/chef.pid"
load_rc_config $name
export rc_pid
chef_stop()
{
    pidfile="/var/run/chef.pid"
    rc_pid=`cat ${pidfile}`
        kill $rc_pid
}

run_rc_command "$1"

chef.erb

[rilindo@chef chef-client]$ cat ./templates/freebsd/rc.conf.d/chef
chef_enable="YES"

With ERB, I could have easily have placeholders in the code so that it can be populated with node-specific information automatically. I did not do that in this case, though. That is for another time.

Finally, I updated the service code from:

when "bsd"
  log "You specified service style 'bsd'. You will need to set up your rc.local file."
  log "Hint: chef-client -i #{node["chef_client"]["client_interval"]} -s #{node["chef_client"]["client_splay"]}"

else
  log "Could not determine service init style, manual intervention required to start up the chef-client service."
end

when "bsd"
  case node['platform']
    when "freebsd"

      directory "/etc/rc.conf.d" do
        owner "root"
        group "wheel"
        mode "0644"
        action :create
      end
      template "/etc/rc.d/chef-client" do
        source "#{dist_dir}/rc.d/chef-client.erb"
        owner "root"
        group "wheel"
        mode 0755
      end

      template "/etc/rc.conf.d/chef" do
        source "#{dist_dir}/rc.conf.d/chef.erb"
        mode 0644
        notifies :start, "service[chef-client]", :delayed
      end

      service "chef-client" do
        action [:start]
      end

    else
      log "You specified service style 'bsd'. You will need to set up your rc.local file."
      log "Hint: chef-client -i #{node["chef_client"]["client_interval"]} -s #{node["chef_client"]["client_splay"]}"
  end
else
  log "Could not determine service init style, manual intervention required to start up the chef-client service."
end

I am not sure if this is quite “rubyish”, but it works.

At that point, I uploaded the cookbook:

knife cookbook upload chef-client

Added the recipe to the freebsd node:

knife node run_list add freebsddev.monzell.com  "recipe[chef-client]"

And ran chef-client. Thechef-client program sees the receipe and install the files to the appropriate locations:

I am mostly done now. I just need to start it up with:

/etc/rc.d/chef-client start

I should be able to start automatically. However, getting it to start up automatically upon installation has so far just returns me with:

Essentially, it couldn’t find the PID file in the expected location, which is no surprise, as I had been running chef-client manually without any arguments. Hopefully I can figure out a fix for that soon.
