Digitally signing Ansible Content Collections using private automation hub

Red Hat Ansible Automation Platform can manage and execute automation made from many different origins, coming from Red Hat product teams, ISV partners, community and private contributors.

Here is a typical makeup of an automation play that is launched from automation controller:

1. A job template is executed by automation controller and is a playbook.
2. The playbook runs inside of an automation execution environment by the automation controller.
3. The automation execution environment is made using the execution environment builder (ansible-builder tool).
4. When ansible-builder creates the execution environment, it includes dependencies.
5. The dependencies are Ansible Content Collections and their requirements.
6. Collections and their dependencies can be private, community-based, or supplied by Red Hat or its ISV partners.

Previously, there was no way to verify that a Collection downloaded from either Ansible automation hub (console.redhat.com) or private automation hub was developed and released by its original Collection maintainer. This is a potential security issue and breaks the supply chain from creator to consumer.

Providing security-focused features in Ansible Automation Platform 2 continues to be a priority, to enable the execution of certified and supported automation anywhere in your hybrid cloud environment. New in Ansible Automation Platform 2.2  is Continue reading

How to reduce cloud costs

The more workloads that you migrate to the cloud, the more difficult it becomes to predict monthly cloud costs. Cloud services vendors such as Amazon, Google and Microsoft can help organizations avoid capital costs for new hardware, but that doesn’t necessarily mean that you have made the most cost-effective decisions about the particular services that these and other cloud vendors offer.And while it is great that you’re only paying for the services you need, trying to parse your monthly bill requires the skills of a CPA, a software engineer, a commodities trader and a sharp eye for the details.To read this article in full, please click here

MLAG Deep Dive: Layer-3 Forwarding

The layer-2 forwarding and flooding in an MLAG cluster are intricate but still reasonably easy to understand. Layer-3 gets more interesting; its quirks depend heavily on layer-2 implementation. While most MLAG implementations exhibit similar bridging behavior, expect interesting differences in routing behavior.

We’ll have to expand by-now familiar network topology to cover layer-3 edge cases. We’ll still work with two switches in an MLAG cluster, but we’ll have an external router attached to both of them. The hosts connected to the switches belong to two subnets (red and blue).

Counting the days on Linux

Have you ever wondered how many days it’s been since you started your diet, begun your daily jogs, or were first working with Linux? If you can remember the start date, a simple Linux script can count the days for you. All you need is the date command and a calculation that turns your dates into seconds, subtracts the start date from the end date and then divides the result by the appropriate number to turn the seconds into the corresponding number of days.Why seconds? The reason for the conversion to days is that the date command can display a date as the number of seconds since the start of the Linux epoch—10=970-01-01. This is the only option date provides for looking at the time difference between two calendar dates.To read this article in full, please click here

AWS moves towards quantum networking

AWS is making a push into an area of quantum computing that hasn't received as much attention as other aspects: networking.The AWS Center for Quantum Networking (CQN) will work toward solving scientific and engineering challenges around creating new hardware, software, and applications for quantum networks, AWS stated. The center will expand other AWS quantum work being done at the vendor’s AWS Center for Quantum Computing, the Amazon Quantum Solutions Lab, and its Amazon Braket service.

StorONE enables HDD connectivity over NVMe-oF

StorONE has introduced what it claims is the first storage platform to enable connectivity between standard mechanical hard disk drives (HDD) and flash drives over NVMe-over Fabric (NVMe-oF) infrastructures, which it says can reduce the cost of an NVMe solution by tenfold or more.Storage arrays have traditionally been separated by drive make. You have all-flash arrays and all-hard-disk arrays but not a mix of the two. Typical operation is to put “hot” data, or data that is frequently accessed, on the much faster SSDs, and put less frequently accessed data on the slower HDDs. That approach requires two or more separate arrays, plus the connection between them.To read this article in full, please click here

Contributing Cool Community Content to Calico

It’s right there on our community page—the statement that “Project Calico is first and foremost a community.”

With that in mind, we wanted to make it easier for new contributors to get involved. It’s a win-win scenario—developers experience less frustration, they can get their work done, and have their contributions considered. Plus, the project can easily benefit from the contributions.

Recently, we have been doing a lot of work to simplify the contribution process, and to encourage, recognize, thank, and reward contributors. For example, earlier this year we announced our Calico Big Cats ambassador program and began using a single monorepo architecture. Read on and we’ll dig into that more.

In my role as Lead Developer Advocate for Project Calico, up until now, when I wanted to make a bug fix or improve something, I needed to feed that back to the development team for them to implement. In this blog post, though, I’m going to test out the new contribution process myself, document it for others, make improvements, and see what I can learn.

The Project Calico home page is a great place to find a contribution to make, so I headed there. Following the “Find a good Continue reading

BGP Intra-AS and Route Reflection

Since BGP is designed to be an overlay protocol, it doesn’t really have good mechanisms for carrying routes within an autonomous system. In this video, I’m discussing some of the techniques developed to carry routes within an AS, including route reflectors.

CLI Shortcut for Visual Studio Code on MacOS

I really do like Microsoft’s Visual Studio Code for editing code, so much so that I can forgive it for being an electron app. However when I code in go, the way the go’s syntax validation works means that each app folder needs to be opened in its own Visual Studio Code window – and as somebody supremely lazy I find this to be an irritating thing to have to do.

Opening a Folder in a New Window

It’s not actually that big of a deal, but having to execute File->New Window, then File->Open Folder…, then browsing to the folder I want to open often feels clunky and superfluous when half the time I’ve already browsed to that folder in the shell. So here’s the dumb shortcut which makes my life easy on MacOS:

/usr/local/bin/vsc:
#!/bin/zsh
# 
"/Applications/Visual Studio Code.app/Contents/Resources/app/bin/code" --new-window "`pwd`"

So now if I’m in a folder I can just enter the command vsc and a new Visual Studio Code window opens focused on my current directory.

Stupidly simple, yes, yet I use it multiple times a day and I’m remarkably happy about it. It takes all sorts, I guess.
