Interesting approach (minus some of the ECR security benefits as mentioned in the comments).

Alex Kretzschmar, also known as ironicbadger, has posted an insightful YouTube Video on how to get started with #Docker and #Tailscale. This video is perfect for those looking to enhance their #DevOps skills and secure their network connections. In his insightful video, Alex Kretzschmar (aka ironicbadger) walks viewers through the process of setting up Docker with Tailscale. This combination allows for easy, #secure access to Docker containers across various environments. Alex covers the basics of Docker containerization and how Tailscale's mesh #VPN simplifies secure connectivity. His step-by-step guide ensures that even beginners can follow along and implement these tools efficiently. For more details, check out the full guide on the Tailscale blog.

With re:Invent kicking off next week, we expect to see a lot of announcements and hype around the AWS universe. The improvements we've seen in the lead up to re:Invent are already pretty impressive. So, lets use this fantastic opportunity to get together and discover, discuss and enjoy the changes before the Christmas break. Save your seat for the last meetup of the AWS user group in Dresden on Dec 12th: 👉 https://lnkd.in/e7ET6DkP Note that there is a difference how we do these recaps in Dresden compared to other cities. While we will have an overview of the announcements ready, we would be happy if some of our attendees can explain the announcements that they like the most and why. That way we will have more of a discussion about what's hot. Plus, of course I will bring my "cards against developers" game and we can have some fun afterwards 😁 Special thanks to our host, ZEISS Digital Innovation; without the support of companies like you such events would not be possible! 👏 (and of course we are also looking for hosts for 2025 already; ping Paweł or myself if you have some space for a bunch of AWS enthusiasts) #aws #awscommunity #reinvent #dresden

🚀 Exploring the Zalando Operator: A Deep Dive into Kubernetes Postgres Management 🐘 Managing PostgreSQL in production can be a challenging task, especially when aiming for high availability and operational simplicity. Enter Zalando Operator, built on top of the robust Patroni tool, and leveraging the power of Kubernetes to streamline Postgres cluster operations. 🌐 Key Highlights: 1️⃣ Patroni as the Backbone: Patroni simplifies Postgres lifecycle tasks like provisioning, failover, and reconciliation. 2️⃣ Spilo: The All-in-One Container: Bundles Postgres, Patroni, and essential tools. Scripts and configurations make Spilo efficient for early container adopters, though keeping it up-to-date can be a challenge. 3️⃣ Zalando Operator in Action: Adds a Kubernetes-native layer on top of Spilo for managing Postgres clusters with CRDs. Mature features like switch-over/fail-over, version upgrades, and seamless integration with GitOps workflows like ArgoCD. Check out my post to learn more. #PostgreSQL #Kubernetes #DatabaseManagement #Patroni #ZalandoOperator https://lnkd.in/eWMtWAuE

Most people in these days are working with containerized applications, orchestrators, schedulers. These technologies evolved a lot and looking at the past, from the time of chroot environments, systemd-nspawn, docker, rkt, the first CoreOS with The Apache Software Foundation Mesos, the intent of HashiCorp Nomad, Docker, Inc Swarm, nice memories. Then the OpenContainer Initiative and today the Kubernetes main role in the current scenario for cloud native technologies and platforms! We have to remember that the OCI is not just about LXE, rkt, docker, podman, containerd, but also about CRI-O, a container runtime interface that can easily run under our favorite orchestration tool. Are you ready to try the new improvements? And why not on kubernetes? CRI-O 1.31 .... Kubernetes 1.31 ... today is Thursday ... A plan for this weekend?

🌍 The World of Containerization with Poda James 🌐 Cloud Infrastructure & Linux System Administrator 🛠️ Lets take it from top what is DOCKER? Alright, think of Docker as your "magical moving box" for apps. 🚀 Magic Moving Box: Docker is like a magic box that packs up your app so it can travel smoothly. 🧩 App Kit: It includes every piece your app needs—libraries, settings, the works. 📦 Container: The box, or container, keeps it all tidy. 💻 Runs Anywhere: Your app can go from laptop to server (even spaceship!). 🎉 No More Drama: No “works on my machine” excuses, just smooth sailing anywhere your app goes! Let me give an example with your favorite Application on your phone >> mmm lets take Spotify for example. Think of Docker like your favorite app, Spotify 🎶. When you use Spotify, it streams music from its servers, but the app itself contains everything you need to enjoy your music—playlists, settings, and your favorite tracks. Docker does the same for software applications: it packages everything an app needs to run (like libraries and configurations) into a "container." This way, no matter where you run the container—your laptop, a server, or even in the cloud—it works the same way, just like Spotify works on any device! Now lets talk about why docker is important how its used on your favorite application! To illustrate how Docker helps run an application like Spotify, here’s a simplified breakdown: User Interface 🖥️: When you open the Spotify app, you interact with the user interface, which is served by a Web Server Container. Application Logic 🎵: The app's logic, such as searching for songs or managing playlists, runs in an Application Container. Database 📊: User data and music catalogs are stored in a Database Container, which handles all data transactions. Communication 🔗: These containers communicate over a Docker Network, ensuring smooth interaction and data flow. Scaling 📈: As more users join, Docker can quickly spin up additional containers to manage the load, maintaining performance and reliability. Lets talk about the technical aspect of docker the next post. Happy reading!! Happy weekend!!
