Resetting opscode-reporting password

One in a while upgrading opscode-reporting goes wrong. Or it doesnt start, you do manual clean up, and basically passwords go out of sync.

Solution is pretty straight forward - reset the passwords to what the system things the passwords should be.

1.
Open up /etc/opscode-reporting/opscode-reporting-secrets.json
Grab opscode_reporting & opscode_reporting_ro passwords and pipe them to opscode-pgsql

echo "ALTER USER opscode_reporting PASSWORD 'XXXXX' " | su -l opscode-pgsql -c 'psql'
echo "ALTER USER opscode_reporting_ro PASSWORD 'XXXXX' " | su -l opscode-pgsql -c 'psql'

You should get the result "ALTER ROLE" from each of the 'echo' commands

2.
Next, make sure rabbitmq password is in sync:
In the same .json file, in the "opscode_reporting" section, grab the "rabbitmq_password" and use it in place of XXXXX

PATH=/opt/opscode/embedded/bin:$PATH rabbitmqctl change_password runs XXXXX

3.
then chef-server-ctl restart opscode-reporting


4.
And finally, you might still be broken.
If you look at the process list and see an error similar to below, send the HUP to svlogd to reload the configs.

root      1456  0.0  0.0   4092   196 ?        Ss    2015   3:12 runsvdir -P /opt/opscode/service log: vlogd: pausing: unable to rename current: /var/log/opscode/opscode-reporting: file does not exist?svlogd: pausing: unable to rename current: /var/log/opscode/opscode-reporting: file does not exist?svlogd: pausing: unable to rename current: /var/log/opscode/opscode-reporting: file does not exist?svlogd: pausing: unable to rename current: /var/log/opscode/opscode-reporting: file does not exist?

So grab the correct pid by running chef-server-ctl status

...
run: opscode-reporting: (pid 17407) 30088s; run: log: (pid 32415) 88051s
...

kill -HUP 32415

Chef - Passing output of one resource as input to the next

There are a couple of ways to do that.

One is via lazy

directory '/tmp' 

file '/tmp/alex.txt' do
  content 'sudo make me a sandwitch'
end 

ruby_block "something" do
    block do
      command = 'cat /tmp/alex.txt'
      command_out = shell_out(command)
      node.set['a'] = command_out.stdout
    end
    action :create
end 

file '/tmp/alex2.txt' do
  action :create
  owner 'root'
  group 'root'
  mode '0644'
  content lazy { node['a'] }
end
