Dagger is an innovative startup aimed at simplifying and revolutionizing DevOps automation and software delivery. Created to address Docker's unattended gaps, Dagger streamlines software building, testing, and deployment, exhibiting immense growth potential and wide applications in fostering software ecosystems. For a few years now, they've been publicly iterating on the idea of a programmable and portable automation system for software building, testing, and deploying. In this episode, they cover many topics around Docker and Dagger. I've been convinced that I need to start trying out Dagger in my projects.The live recording of the complete show from November 16, 2023 is on YouTube (Ep. #241)★Topics★Dagger websiteCreators & Guests

Registry is getting an upgrade: Inside OCI artifacts
The OCI specifications for registry and image are getting a minor version number update to 1.1 soon, and this could be a big deal for anyone storing artifacts other than images somewhere in their infrastructure.

NetBackup for Kubernetes
Bret is joined by Demetrius Malbrough and Joseph D'angelo from Veritas, the company that makes NetBackup amongst many other data protection tools.NetBackup has been around at least 25 years and I've been using it over 20 years, although not recently. So we had the two gentlemen from Veritas on the show to break down the evolution of NetBackup to a Kubernetes native backup solution. We also talked about additional products that make sense in a backup context, like their InfoScale storage management solution, and we tried to break down some of the technicals. What are we talking about when we mean deploying NetBackup on Kubernetes? How does InfoScale fit into that? And generally, just helping me catch up with the last few years as NetBackup 10.0 has been released. I asked lots of questions and we got some interesting questions from the audience.The Live recording of the complete show from October 19, 2023 is on YouTube (Ep. #238).★Topics★Veritas Kubernetes solutionsInfoScale Free Developer Edition60 day–trial of Veritas InfoScale for KubernetesCreators & Guests
