$ java -jar jenkins-cli.jar -s http://localhost:9000 install-plugin findbugs
findbugs is neither a valid file, URL, nor a plugin artifact name in the update center
No update center data is retrieved yet from: http://updates.jenkins-ci.org/update-center.json
findbugs looks like a short plugin name. Did you mean 'null'?


# Specifying a full URL works!
$  java -jar jenkins-cli.jar -s http://localhost:9020 install-plugin http://updates.jenkins-ci.org/download/plugins/AdaptivePlugin/0.1/AdaptivePlugin.hpi

# Get the update center ourself

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

'''
Register a mDNS/DNS-SD alias name for your computer using the Avahi daemon

This script will register an alternate CNAME alias besides your hostname,
which could be useful for ex. when serving several http virtual hosts to 
your ffriends on the local network and you don't want to make them configure
their /etc/hosts.

Why a CNAME? You could also publish your current address with avahi-publish-address

Masterless Puppet using a Puppetfile

The problem

When running Puppet in masterless mode, meaning there is no Puppet Master for the node to connect to, one of the problems you have to solve is how to get all your Puppet modules onto the node. Without going into all the possible ways of doing this, one nice and clean way to solve the problem is to use a Puppetfile.

If you know what a Ruby gemfile is, you can guess what a Puppetfile is. If you don't, think of a very simple list declaring the modules that a node should get, including ways to get those modules. Like this:

forge 'forge.puppetlabs.com'

This is a snippet that will create a new user in jenkins and if security has been disabled , it will enable it :)

import jenkins.model.*
import hudson.security.*

def instance = Jenkins.getInstance()

def hudsonRealm = new HudsonPrivateSecurityRealm(false)
hudsonRealm.createAccount("MyUSERNAME","MyPASSWORD")
instance.setSecurityRealm(hudsonRealm)
