Understanding networking in Kubernetes
Posted on November 3, 2023, Level intermediate Resource Length medium
Kubernetes relies on Container Network Interface (CNI) plugins to assign IP addresses to pods and manage routes between all pods. Kubernetes doesn't ship with a default CNI plugin, however, managed Kubernetes offerings come with a pre-configured CNI. By Peter Jausovec.

How container networking works at Platform.sh
Posted on November 2, 2023, Level intermediate Resource Length medium
We'll take a look at how we wire (most of) it up. In particular, we'll go over the role of the Platform.sh edge layer, and describe in detail how we network hosts and containers together. From the networking perspective, our job is to make sure that a request directed towards your web server reaches the right container, and that container is able to communicate with other containers that your hosted application depends upon, all while making sure that someone else's container cannot talk to one of your containers.

How IKEA Retail standardizes docker images for efficient machine learning model deployment
Posted on October 22, 2023, Level beginner Resource Length long
What do Docker and IKEA Retail have in common? Both companies have changed how products are built, stored, and shipped. In IKEA Retail's case, they created the market of flat-packed furniture items, which made everything from shipping, warehousing, and delivering their furniture to the end location much easier and more cost effective. This parallels what Docker has done for developers. Docker has changed the way that software is built, shipped, and stored, with Docker Images taking up much less space "shelf" space.

How to add a Software Bill of Materials (SBOM) to your containers with GitHub Actions
Posted on May 9, 2023, Level intermediate Resource Length medium
Learn how to add a Software Bill of Materials (SBOM) to your containers with GitHub Actions in a few easy steps. An SBOM is an inventory of the components that make up a software application. It is a list of the components that make up a software application including the version of each component. The version is important because it can be cross-reference with a vulnerability database to determine if the component has any known vulnerabilities. By Alex Ellis.

Distributed cloud-native graph database with NebulaGraph Docker extension
Posted on May 4, 2023, Level intermediate Resource Length medium
Graph databases have become a popular solution for storing and querying complex relationships between data. As the amount of graph data grows and the need for high concurrency increases, a distributed graph database is essential to handle the scale. Finding a distributed graph database that automatically shards the data, while allowing businesses to scale from small to trillion-edge-level without changing the underlying storage, architecture of the service, or application code, however, can be a challenge. By Wey Gu and Ajeet Singh Raina.

Six docker compose best practices for dev and prod
Posted on December 26, 2022, Level intermediate Resource Length medium
Docker solves the "but it runs on my machine" problem by introducing containerization. However, with a multifaceted code base, you must simultaneously run several containers like the back and front end. Further, this will require you to leverage tools such as Docker Compose. By Regis Wilson.

How to fix and debug Docker Containers like a superhero
Posted on October 21, 2022, Level intermediate Resource Length medium
While containers help developers rapidly build and run cross-platform applications, creating error-free apps remains a constant challenge. And while it's not always obvious how container errors occur, this mystery is even harder for newer developers to unravel. Figuring out how to debug Docker containers can seem daunting. By Tyler Charboneau.

How to monitor Docker with Telegraf and InfluxDB
Posted on June 14, 2022, Level intermediate Resource Length medium
Docker is an increasingly popular choice for businesses dealing with containerized applications. However, as with any new technology, Docker introduces complexities that need to be managed. Some of these complexities relate to infrastructure and application monitoring. Due to the abstraction offered by containers, traditional monitoring solutions might not be suitable for Docker-based workloads. By Cameron Pavey
