Photo by Hush Naidoo Jade Photography on Unsplash
Are you tired of manually creating Ansible modules for every new tool, cloud service, or appliance you need to manage? Look no further than the Ansible Content Builder. This powerful Python tool can generate Ansible modules for any appliance or service with a network CLI, NETCONF, or OpenAPI. In this blog post, we'll show you how to use the Content Builder to scaffold your Ansible modules to create good, consistent content for your cloud platform of choice. We'll also explore how the Content Builder can help you onboard new tools and services into the Ansible ecosystem with ease. So if you're looking to supercharge your Ansible workflow and automate any cloud platform, this post is for you!
The Ansible Content Collections for hybrid cloud automation house multiple modules. These modules handle the creation, deletion, modification (and more) of cloud resources. While developing individual modules for different resources of the cloud platform can lead to modularity and ease of use, reinventing the wheel can be error-prone and time-consuming. Standardizing the common steps that are similar but differ based on limited parameters can solve many problems encountered while developing these modules. This is achieved Continue reading
BGP Management with Ansible Validated Content using the network.bgp collection
At AnsibleFest 2022, we announced a new addition to the content ecosystem offered through the platform which is Ansible validated content. Ansible validated content is use cases-focused automation content that is packaged as Collections that contain Ansible plugins, roles and playbooks that you can use as an automation job through Red Hat Ansible Automation Platform.
Now that we understand what Ansible validated content is, we still have to see what it brings to network automation practices. We have already talked about a generic Ansible validated content for network automation which is network.base.
Network Border Gateway Protocol (BGP) is more focused on very specific use cases – managing BGP resources and neighborship, platform-agnostic network automation and enhancing the experience of BGP management by providing production ready -content.
Network BGP Use Cases
The network.bgp Collection enables users to manage the BGP resources independent of platforms, as well as performing BGP health checks. It includes the following capabilities:
- Build Brownfield Inventory. The `persist` action enables users to be able to get the BGP global and address family facts and store it as inventory host_vars. The idea is to have this dynamic inventory as a single source of truth for Continue reading

What’s New: Cloud Automation with amazon.cloud 0.3.0
Last year, we made available an experimental alpha Ansible Content Collection of generated modules using the AWS Cloud Control API to interact with AWS services. Although the Collection is not intended for production, we are constantly trying to improve and extend its functionality and achieve its supportability in the future.
In this blog post, we will go over what else has changed and highlight what’s new in the 0.3.0 release of this Ansible Content Collection.
Forward-looking Changes
Much of our work in release 0.3.0 focused on releasing several new enhancements, clarifying supportability policies, and extending the automation umbrella by generating new modules. Let’s deep dive into it!
New boto3/botocore Versioning
The amazon.cloud Collection has dropped support for botocore<1.28.0 and boto3<1.25.0. Most modules will continue to work with older versions of the AWS Software Development Kit (SDK), however, compatibility with older versions of the AWS SDK is not guaranteed and will not be tested.
New Ansible Support Policy
This Collection release drops support for ansible-core<2.11. In particular, Ansible Core 2.10 and Ansible 2.9 are not supported. For more information, visit Ansible release documentation.

Ansible Automation Platform … You’re using it wrong.
5 things you didn’t know your Red Hat Ansible Automation Platform could do
When we think about automation, we tend to focus on efficiency. Automating simple or even complex tasks to streamline our processes - It’s one of the reasons organizations adopt and implement Red Hat Ansible Automation Platform.
But what if we can take our automation abilities to the next level?
In this blog post, I’m going to highlight 5 things you didn’t know your Ansible Automation Platform could do.
Callback Plugins
Ever need a job to notify you, log events, or capture the performance of a playbook?
Say hello to callback plugins. These plugins provide a way for Ansible to respond to particular events. In order to enable callback plugins, you'll need to tweak your job settings and supply the directory location in the Ansible callback plugins section.
A list of available callback plugins can be found within the Ansible documentation.
JSON Output
Looking for an easy way to view your Ansible output in JSON format? Take advantage Continue reading
Creating a Talos Linux Cluster on Azure with Pulumi
A little over a month ago I published a post on creating a Talos Linux cluster on AWS with Pulumi. Talos Linux is a re-thinking of your typical Linux distribution, custom-built for running Kubernetes. Talos Linux has no SSH access, no shell, and no console; instead, everything is managed via a gRPC API. This post is something of a “companion post” to the earlier AWS post; in this post, I’ll show you how to create a Talos Linux cluster on Azure with Pulumi.
The program I’ll share with you in this post is written in Go, but the process outlined in this post and the accompanying code is equally applicable in other languages supported by Pulumi. (TypeScript is a popular choice for lots of folks.) The code is available in this GitHub repository. It’s based on this documentation from Sidero Labs, and I also found this blog post to be helpful as well.
The Pulumi program follows this overall flow:
- First, the program creates the base infrastructure objects that are required—a resource group, a virtual network, some subnets, and a network security group.
- Next, it creates a load balancer, gets a public IP address for the load Continue reading
Ansible Validated Content: Introduction to infra.osbuild Collection
Introduction to the Image builder use case
During the last year we met with multiple edge customers, covering the automation needs for IT Linux infrastructure at scale across remote locations where there is often no IT staff on site. Think about retail stores, dark stores and warehouses where self-checkout, handhelds and POS devices hosting RHEL are distributed everywhere.
For industrial setups and manufacture, this could be the scenario for small factor servers and storage hosting logging monitoring to gather information about operational activities, which are located in secure facilities.
One of the recurrent needs for our customers with distributed devices is the ability to upgrade Linux devices faster, at scale, mostly due to regulations or security risks. Ideally, you should be able to patch at scale as soon as a vulnerability is identified.
The main challenge with the traditional RPM patching model is that it is incremental, and frequently some Linux devices might have slight differences. That is why there are new edge-focused capabilities and models that start with the premise that you could and should test a whole base image, and once it passes your validations, it should be deployed into all the target devices that Continue reading

Providing Terraform with that Ansible Magic
Late last year, we introduced a Red Hat Ansible Certified Collection Collection for Terraform. This was an important step in automation, as these two tools really are great together and leveraging Ansible's ability to orchestrate other tools in the enterprise made this a no-brainer. Terraform with its infrastructure as code (IaC) provisioning and Ansible’s strength in configuration as code are a synergy that cannot be ignored - we are better together! Organizations are now in the position to utilize their existing infrastructure as code manifests and extend their automation with Terraform and Ansible together.
Now, we are back with help from our partners at Kyndryl and XLAB and adding more value and magic to infrastructure as code - This time we have some extra muscle with an addition to the Red Hat Ansible Certified Content Collection: The Ansible provider for Terraform.
So what does the provider help us with?
Without a provider, we would need to rely on inventory plugins for the different cloud platforms and use filters to grab instance information from our freshly "Terraformed" infrastructure. This allows us to update our inventory so we can run automated tasks against these hosts. This is pretty smooth in Continue reading
Kubernetes Meets Event-Driven Ansible
In today’s fast paced world, every second counts and the ability to react to activities in a timely fashion can mean the difference between satisfying the needs of consumers and meeting Service-Level Agreements. Each are goals of Event-Driven Ansible, which seeks to further the reach of Ansible based automation by responding to events that meet certain criteria. These events can originate from a variety of sources, such as from an HTTP endpoint, messages on a queue or topic, or from public cloud resources. Kubernetes has become synonymous with managing infrastructure and applications in cloud native architectures and many organizations are reliant on these systems for running their business critical workloads. Automation and Kubernetes go hand in hand and Ansible already plays a role within this ecosystem. A new capability leveraging the Event-Driven Ansible framework is now available that extends the integration between both Ansible and Kubernetes so that Ansible automation activities can be triggered based on events and actions occurring within a Kubernetes cluster.
Event-Driven Ansible is designed using a concept called Rulebooks which consists of three main components:
- Actions - Triggering the execution of assets including an Ansible Playbook or module
- Rules - Determination of whether received events Continue reading
Enhancing/Maximizing your Scaling capability with Automation Controller 2.3
Red Hat Ansible Automation Platform 2 is the next generation automation platform from Red Hat’s trusted enterprise technology experts. We are excited to announce that the Ansible Automation Platform 2.3 release includes automation controller 4.3.
In the previous blog, we saw that automation controller 4.1 provides significant performance improvements as compared to Red Hat Ansible Tower 3.8. Automation controller 4.3 is taking that one step further. We will elaborate on an important change with callback receiver workers in automation controller 4.3 and how it can have an impact on the performance.
Callback Receiver
The callback receiver is the process in charge of transforming the standard output of Ansible into serialized objects in the automation controller database. This enables reviewing and querying results from across all your infrastructure and automation. This process is I/O and CPU intensive and requires performance considerations.
Every control node in automation controller has a callback receiver process. It receives job events that result from Ansible jobs. Job events are JSON structures, created when Ansible calls the runner callback plugin hooks. This enables Ansible to capture the result of a playbook run. The job event data structures contain Continue reading

Datacenter System Makers Leary But Not Weary
The central banks of the world, led by the European Central Bank and the US Federal Reserve, want to curb inflation and they are willing to cause a small recession or at least get very close to one to shock us all into controlling the acquisitive habits we developed during the lockdowns of the early years of the coronavirus pandemic. …

Troubleshoot RDS connectivity issues with Ansible validated content
The Ansible validated content cloud.aws_troubleshooting introduces a role named troubleshoot_rds_connectivity. This role helps you troubleshoot AWS Relational Database Service (RDS) connectivity issues from an EC2 instance.
The role diagnoses connectivity issues between an EC2 instance and an Amazon Relational Database Service instance by ensuring that the RDS instance is available and checking the associated security group rules, network access control lists, and route tables for potential connectivity issues.
To do this, the role will need the EC2 instance identifier to test connectivity from the RDS instance identifier to connect to.
Let's see how this can be used with the following example.
Configuration
We have an RDS instance and an EC2 instance running in the same VPC (virtual private cloud) with the CIDR block 10.1.0.0/16.
The RDS instance is running on two subnets with the following CIDR blocks 10.1.1.0/24 and 10.1.2.0/24.
The EC2 instance is running in another subnet in the VPC with the CIDR block 10.1.10.0/24. The EC2 instance has been assigned the following private IP address 10.1.10.41.
In the initial configuration, a security group is attached to the VPC with the following Continue reading
Maximize your hybrid cloud mastery with the Ansible validated content
In today's environment, mastering the hybrid cloud has become a key factor in IT transformation and business innovation. In this context, network complexity can be a nightmare, especially as organizations expand their infrastructure and embrace hybrid cloud and multi-cloud strategies. Without automation, monitoring and controlling network routing, infrastructure, and security in a hybrid and multi-cloud environment are difficult to manage. Furthermore, identifying and resolving network performance issues in these infrastructures are quite challenging.
In one of the previous blogs, titled “Crank up your automation with Ansible validated content”, Nuno Martins highlighted the Ansible validated content included in Red Hat Ansible Automation Platform 2.3.
In this blog post, we will show you how to leverage the amazon.aws_troubleshooting Collection for hybrid cloud to troubleshoot network performance issues and maximize your hybrid cloud mastery. In particular, we’ll use the aws_troubleshooting.connectivity_troubleshooter role.
First, let’s take a look at the amazon.aws_troubleshooting Collection.

Creating a Talos Linux Cluster on AWS with Pulumi
Talos Linux is a Linux distribution purpose-built for running Kubernetes. The Talos web site describes Talos Linux as “secure, immutable, and minimal.” All system management is done via an API; there is no SSH access, no shell, and no console. In this post, I’ll share how to use Pulumi to automate the creation of a Talos Linux cluster on AWS.
I chose to write my Pulumi program in Go, but you could—of course—choose to write it in any language that Pulumi supports (JavaScript/TypeScript, Python, one of the .NET languages, Java, or even YAML). I’ve made the Pulumi program available via this GitHub repository. It’s based on these instructions for standing up Talos Linux on AWS.
The Pulumi program has four major sections:
- First, it creates the underlying base infrastructure needed for a Talos Linux cluster to run. This includes a VPC (and all the assorted other pieces, like subnets, gateways, routes, and route tables) and a load balancer. The load balancer is needed for the Kubernetes control plane, which we will bootstrap later in the program. This portion also creates the EC2 instances for the control plane.
- Next, it uses the Talos Pulumi provider to generate the Talos Continue reading
Using Red Hat Insights as a source of events for Event-Driven Ansible automation
One of the key announcements at AnsibleFest 2022 was the introduction of the Event-Driven Ansible developer preview. This technology is currently available on GitHub and accessible by technology providers and end users to provide feedback and drive the ecosystem. ISVs and consulting/service partners are specifically invited to create event driven automation content that makes it easy for customers to use in joint solutions.
Red Hat Insights events as a source for Event-Driven Ansible
Red Hat Insights, is a managed service that is included in every Red Hat subscription. It continuously analyzes platforms and applications to help enterprises manage hybrid cloud environments, and can trigger events through its Notifications service. Each account configures how and who can receive these events, with the ability to perform actions depending on the event type. For example, one may want to forward new recommendations found for Red Hat Enterprise Linux (RHEL) system configuration to a specific team by email, and/or create a new ticket in ServiceNow for the Operations team to handle. Others may want to forward all triggered events to Splunk for external analysis and troubleshooting. Through its Integrations service, Insights provides end-point integrations to Splunk, ServiceNow, Slack, as well as Continue reading
Red Hat Ansible Automation Platform now available on Google Cloud Marketplace
Breaking news! Red Hat just announced Ansible Automation Platform’s availability on Google Cloud Marketplace.
I’d like to take a few moments to provide some more details about this offering and why you should consider accessing Ansible Automation Platform directly from the Google Cloud Marketplace.
As organization’s hybrid cloud environments continue to grow in complexity, so does the need to increase efficiency and speed. The solution is to leverage an automation platform that can help any organization create, manage, and scale their automation efforts across the entire IT infrastructure.
