Re: [Puppet Users] Re: Best way to change settings on an individual node

[Rob Nelson]

If the only difference is in the virtual hosts, then you should be able to
apply the same classes to each and use different data only. Hiera, included
with puppet, is a key/value pair lookup tool that can help here, so each
node would receive their vhost data and only their vhosts. I think you
should find plenty of hiera docs on puppet’s websites and others (I’m on my
phone or I’d grab a link or three) and we are glad to help you here or on
slack if you need more help with it.

[Puppet Users] Re: Best way to change settings on an individual node

[jackandnora]

Thanks Eric.  I've read that documentation and it always refers to multiple 
nodes.  It just feels like I'm doing it wrong.  If I have a small group of 
4 web servers that all run different virtual hosts, the only way to use the 
node classification groups is to pin each node to it's own group and apply 
the classes to them.  I can do that, it just feels like there is a better 
way.

[Puppet Users] Re: Best way to change settings on an individual node

[Eric Sorenson]

Hi Jack, for puppet enterprise there's a built-in workflow for assigning 
classes to nodes - the phrase you're looking for is called "node 
classification" in puppet-speak.  here's the relevant 
doc: 
https://puppet.com/docs/pe/2017.3/managing_nodes/grouping_and_classifying_nodes.html

hope this helps!

Re: [Puppet Users] multiple puppetdb, single postgres

[Christopher Wood]

Running two puppetdb in front of a single postgresql here and it's fine. The 
puppetservers use one puppetdb for everything and the second puppetdb is for 
monitoring and interactive use. The only hiccoughs are when trans-oceanic links 
blip.

The puppetdb instances are managed using puppet and at my SLA levels I get to 
shrug and say that agent runs will fail for a minute or so during the upgrade. 
Depending on your SLA you may have to upgrade at a specific time or swap 
servers behind a load balancer or something else quicker.

If I had a tighter SLA I would build new upgraded puppetdb hosts instead of 
upgrading in place. (Then repoint the puppetservers and turn down the old 
puppetdb hosts.) I haven't had schema issues during puppetdb upgrades.

For the puppet 4->5 upgrade I have a new 1xPostgreSQL9.6+2xPuppetDB5 set built, 
the upgraded puppetservers will fill them up soon enough.

[Puppet Users] multiple puppetdb, single postgres

[Fabrice Bacchella]

Is there any risk running multiple puppetdb reading or perhaps writing to a 
single postgres database ?

For my understanding, all puppetdb's data are stored in pg, so there is no 
coherency problems, but too much caching on pdb's side might break that 
assumption.

There is also the schema consistency. Upgrading one puppetdb without checking 
the other might break it.

Is there any other failure case that I didn't think about ?

The goal is not to have a full HA solution, but be able to upgrade the servers 
regularly without service disruption, as our puppetdb is used by other tools 
than the puppet server.

[Puppet Users] Best way to change settings on an individual node

[jackandnora]

Hi,
I'm a new puppet enterprise user (first post!) and I need to change 
some settings on an individual node.  The module is created and it works in 
my testing, but every method of applying the module to one machine feels 
like I'm doing it wrong. What is the best way to accomplish this?  Feel 
free to point me to some documentation, if I'm simply missing something. 

Thanks,

Jack

Re: [Puppet Users] Regenerating expiring agent cert on the master host (not CA cert)

I did:

# puppet cert clean puppet0.example.com
# rm -v /var/lib/puppet/ssl/ca/signed/puppet0.example.com.pem \
/var/lib/puppet/ssl/certs/puppet0.example.com.pem \
/var/lib/puppet/ssl/certificate_requests/puppet0.example.com.pem \
/var/lib/puppet/ssl/private_keys/puppet0.example.com.pem

then restarted nginx and unicorn then:

# puppet agent --test

and things seemed okay from the on.

Cheers,
Andy
