As infrastructure grows to hundreds and thousands of nodes, the capacity of the Puppet server reaches a limit. Load balancing in multiple Puppet servers is an optimal way to handle load and provide redundancy.

Load Balancing in Puppet Servers to Handle Scaling
15:51

As infrastructure grows, isolating the Puppet server components is a better way to manage them, rather than having a monolithic Puppet server node. Let’s take a look at isolating and centralizing the Puppet certificate authority service, which is an important step in this process.

Creating a Centralized CA Server for Authentication
04:05

With the growth in the number of agent nodes, maintaining a database and the history of node configuration and metadata is crucial for any infrastructure. PuppetDB helps to maintain this database and also aids in configuration via exported resources.

Understanding Exported Resources and Configuring PuppetDB
14:19

Infrastructure management involves services with server and client based models. The server has to push or pull the data from various nodes in the infrastructure for which it needs the node specific information. To automate this process, the methods of exporting and collecting in Puppet modules are extremely useful.

Exporting and Collecting in Modules using PuppetDB
14:00

After the data from thousands of nodes are stored in a database, they are not very useful, unless they can be queried and visualized using structured querying mechanisms. Different Puppet query mechanisms and dashboards helps in solving these problems.

Using the PuppetDB API and Dashboard
12:30

As the number of nodes and service roles grow in an infrastructure, it is important to have proper node classification mechanisms so that nodes are able to receive catalogs correctly and without latency. Proper manageable node classification methods are also desirable.

External Node Classification Using Scripts
09:00

Hostname based node classification often gets very complex and it is easier to switch to other node classification methods. Apart from providing data isolation from code, Hiera can also be an effective framework to provide node classification data based on metadata such as facts.

Node Classification Using Hiera
09:35

Running Puppet components in Docker containers is a bit different than doing it on a physical or virtual machine. It is important to understand how the service components work in an isolated manner and also in the form of an application stack.

Running Puppet server side components in Docker Containers
17:21

Running Puppet agent in Docker Containers to automate them is different from the general process; given the fact that container based dynamic environments don’t have hostnames for the containers and system based process control systems are unavailable in containers.

Automating Docker Containers Using Puppet Agent
12:29

The fact that containers are able to be spawned within few seconds is true. This is due to the fact that Docker images already have all the configurations baked in them and provisioning during the container launch is not required, thus bringing down the deployment time. Creating images is a crucial step in container based environments.

Creating Docker Images
13:12

Once Puppet server side components and containers are ready to be spawned using Docker images, it is important that we are able to launch application stacks involving multiple components such as application and database. Docker Compose can be managed efficiently by use of respective Puppet modules and help us in managing container based application stacks.

Running Applications in Docker Using Puppet
11:04

Once infrastructure reaches a considerable size, a requirement is to be able to perform specific tasks on specific nodes. Managing and maintaining an inventory of role based nodes is a tedious process. MCollective can be a very efficient tool in implementing orchestration which helps us to target nodes based on metadata and run specific tasks

Configuring MCollective for Orchestration in Puppet
16:04

Although facter provides a lot of system facts, often in complex environments, they are not enough. By writing custom facts based on our infrastructure, we can add meaningful custom data to our infrastructure nodes based on which complex tasks can be performed.

Writing Custom Facts
13:37

Puppet built-in types are very helpful in writing configurations. However, for simplified use of Puppet modules, often writing custom types are very important. For users who don’t wish to get into the complex methods of writing Ruby based Puppet types, resource types are a simpler alternative where custom types can be written using the Puppet language.

Writing Custom Resource Types
05:05

With the numerous tools and services available in the infrastructure ecosystem, it is quite exhausting and time consuming to write Puppet modules for them from scratch using built-in Puppet types. For such scenarios, advanced Puppet types can be written using Ruby which can simplify custom tasks.

Writing Custom Puppet Types
06:08

Puppet types are useful in defining custom tasks and processes, however without Providers, Puppet types are unable to do much. If Puppet types are the interface to create custom configurations, providers are the backend logic which actually performs the tasks on the systems. Multiple providers can be written for systems or services with different behaviors.

Writing Custom Providers
10:49

Although Puppet types and Providers help us in creating advanced tasks and interfaces, for some smaller tasks and scenarios, it is enough to create functions. Custom functions can be created in the Puppet language and Ruby to handle such scenarios.

Writing Custom Functions
