Ephemeral & Preview Environments for Compose and Kubernetes

Bret and Nirmal are joined by Lukas Fittl of pganalyze to dive into Postgres in containers, in production, and in CI.

Lukas is an expert and founder of pganalyze, and I invited him on the show to explain a lot of this to us and catch us up with what's going on in the Postgres community, particularly when it comes to containers and production.

We dive into everything around containers with Postgres, some of the new stuff going on in Postgres Land, including tuning and stuff I didn't even know about Postgres, including storing NoSQL data, vector databases for AI and more.

Be sure to check out the live recording of the complete show from February 15, 2024 on YouTube (Ep. #254).

Bret and Nirmal are joined by Melissa McKay, Developer Advocate at JFrog and Docker Captain, to discuss the best and worst of 2023.

We recorded this episode in December of 2023 where we talked through our favorite tools. Whether a DevOps oriented tool or not, it just might be the things we like to use on containers and in Cloud Native DevOps. This is a fun episode of three friends talking about what they love. And I sometimes I think these are the best shows because we didn't plan them out. I hope you enjoy listening to it as much as we did recording it.

Bret is joined by Matan Mishan & Roy Razon of Livecycle to discuss developer platforms and how to improve developer collaboration and speeding up feedback and previews.

We talk about the various delays encountered in pull requests due to feedback processes, and how Lifecycle's tools aim to shorten this feedback loop in Docker Desktop, local CLI with Preevy, and automated CI workflows. I like how Lifecycle provides multiple locations and ways to get access to people in the preview environments that really lets you just fit the different parts of the tool into your workflow, as opposed to one way to do everything. It's great for getting feedback quickly during the PR process, rather than making people set up their own environments to test their changes. I also liked their ideas around how the feedback loops can be improved.

This episode contains great demos so be sure to also check out the live recording of the complete show from December 21, 2023 on YouTube (Ep. #246).

Bret and Nirmal are joined by Michael Irwin, DevRel at Docker, to talk about all the products and features Docker shipped in 2023, and what's coming in early 2024.

Michael has been on this show many times as a Docker Captain and now as a Docker employee, and it's always great to dig into the details of the products with someone who's been using them for so many years as an end-user and now staff at Docker.

Docker did some big things in 2023, but they also shipped some smaller features that we will help you catch up on in this episode.

Bret is joined by Alex Kretzschmar to talk about Tailscale, a universal VPN that connects teams, devices, and development environments for easy access to remote resources.

Alex and I talk about projects he's worked on in containers over the years and then we quickly get into Tailscale and talking about why he joined the team there.

Tailscale is one of those tools that's hard to put down. I've used it for years to connect my personal devices to my home server lab when I'm traveling or servers I might have on the internet that I run temporarily. It connects them all together in a seamless VPN. The product itself comes up a lot in our Discord server when people are talking about needing some secure remote access to something anywhere in the world.

Tailscale keeps adding more and more features, I can't really keep up, so we had Alex on the show to talk about all the new stuff, including a client for Apple TV, which at first, I didn't quite understand why, but now it totally makes sense; and a Kubernetes operator that does some slick things around connecting engineers on their local machines to clusters. I found Alex at the Tailscale booth at KubeCon this year and invited him on the show to talk about this relatively new yet ubiquitous-feeling product.

I break down why Dockerfile frontends exist and how Docker's build engine "BuildKit" is giving us updated Dockerfile features.

The TL;DR of this podcast is to add this to your Dockerfiles as the first line, always and forever.

It'll ensure your Dockerfile will have access to the latest v1.x features of the "Dockerfile frontend" feature of BuildKit.

Solomon started Dagger after he left Docker in 2018 with a few other Docker VPs, including Sam Alba and Andrea Lusardi.

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 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. This episode digs into the problem with artifacts today, and how the OCI and CNCF are planning to fix it with the "one registry to serve them all (artifacts)" in 2023/2024.

Bret is joined by Nirmal and a host of friends from the floor of KubeCon, to talk about the latest news and goings-on.

We wanted to get some of our friends and people we haven't seen in a while that are making great stuff out there on the show for just a few minutes and it's sort of a rapid panel of rotating guests. If you actually watched the video version of this, there's literally people walking in and out of the camera throughout the show.
