Error 400 on SERVER: no 'environments' in {:root_environment=>#<Puppet::Node::Environment:0x7f784c700668 @name=:"*root*", @manifest="/usr/share/puppet/rack/puppetmasterd", @modulepath=[]>

[Luca Mazzaferro]

Hi to Everybody,

I'm working with puppet since some months.

I'm managing a medium environment with some hundreds of nodes.

I installed passenger and everything worked fine following this documentation:

http://docs.puppetlabs.com/guides/passenger.html#example-vhost-configuration

Today I tried to install also Dashboard.

The installation seems to complete correctly then I restarted httpd server and still ok.

But when I go on one client and run the command 

puppet agent --test --environment vargas

I got this error

err: Could not retrieve catalog from remote server: Error 400 on SERVER: no 'environments' in {:root_environment=>#<Puppet::Node::Environment:0x7f784c700668 @name=:"*root*", @manifest="/usr/share/puppet/rack/puppetmasterd", @modulepath=[]>, :current_environment=>#<Puppet::Node::Environment:0x7f784c700668 @name=:"*root*", @manifest="/usr/share/puppet/rack/puppetmasterd", @modulepath=[]>} at top of []

warning: Not using cache on failed catalog

err: Could not retrieve catalog; skipping run

err: Could not send report: Error 400 on SERVER: no 'environments' in {:root_environment=>#<Puppet::Node::Environment:0x7f784c700668 @name=:"*root*", @manifest="/usr/share/puppet/rack/puppetmasterd", @modulepath=[]>, :current_environment=>#<Puppet::Node::Environment:0x7f784c700668 @name=:"*root*", @manifest="/usr/share/puppet/rack/puppetmasterd", @modulepath=[]>} at top of []

same thing if I don't chose the environment.

Instead if I switch off httpd and restart normal puppetmaster everything works fine.

Has anyone already seen this type of error?

Thank you

Cheers.

I have this exact same problem with a fresh install and passenger. I am kinda happy someone else has seen this issue, though I wish I knew why it was.

Check your config.ru and make sure it is correct and in the right location. I had an old one from Foreman there and that was breaking the system apparently. 

[Luca Mazzaferro]

Hi,

thank you for this suggestion.

Probably you are right, indeed; the problem should be there.

Actually the Puppet-Passenger system is working again what I did on my SL6 is:

Update the rack and passenger from the version passenger-4.0.41 to passenger-4.0.42

gem install rack passenger

run again the passenger module installation command for apache2.

passenger-install-apache2-module

 

These two actions didn't solve the situation but when I copied again the config.ru 

cp /usr/share/puppet/ext/rack/config.ru /usr/share/puppet/rack/puppetmasterd/

it starts to work again.

What I guess is this: the Dashboard installation in some way rewrote the config.ru and create the problem.

I will try to install it again making a bkp copy of config.ru before.

Is it possible? Anyone experienced something like this?

I'll keep you updated.

Cheers.

Hi again,

problem solved.

I re-installed also the puppet-dashboard following official information here:

http://docs.puppetlabs.com/dashboard/manual/1.2/bootstrapping.html#installing-from-git

There is an error on the provided dashboard-vhost.conf:

there variable 

RailsAutoDetect

is not supported since passenger 4.0.0 

http://www.modrails.com/documentation/Users%20guide%20Apache.html#_railsautodetect_rackautodetect_and_wsgiautodetect

I used instead 

PassengerEnabled On

Cheers and good luck.

I am having the same problem but I only have uppet-server-3.6.1, without passenger, dashboard, etc.

It works correctly for 10' more or less, then start to give errors like:

May 29 14:15:21 HOSTNAME puppet-master[30831]: no 'environments' in {:root_environment=>#<Puppet::Node::Environment:0x7f654f667018 @config_version=nil, @manifest="/etc/puppet", @name=:"*root*", @modulepath=[], @watching=true>, :current_environment=>#<Puppet::Node::Environment:0x7f654f667018 @config_version=nil, @manifest="/etc/puppet", @name=:"*root*", @modulepath=[], @watching=true>} at top of [[0, nil, nil]]

Downgrade to 3.5.1 since last message and running without problems.

This is https://jira.puppetlabs.com/browse/PUP-2659 which only affects webrick masters when handling concurrent requests. This will be fixed in an upcoming 3.6.2 release.

Thanks!

Google is not smart enough to find that ticket with the pattern "no 'environments' in {:root_environment=>#<Puppet::Node::Environment" :/
