Locking down containers with Docker’s secure blocks

Containers have grown very popular for their flexibility for app development and hosting. For containers to be deployed effectively, they require a substrate to provision and manage resources, place workloads, and adapt to failures. Container orchestration tools like Docker Swarm, Kubernetes, and Marathon simplify the management of container workloads. Unfortunately, many of these systems have not been architected with security in mind and with container orchestrators, compromise of a less-privileged node can allow an attacker to gain control of the whole system or other private resources. We spoke with Diogo Mónica, Docker’s Security Lead, about how the company has been working on secure blocks to allow you to run a “least privilege” infrastructure where any participant only has access to the resources strictly necessary.

How Algolia engineers manage billions of API calls per month without losing sleep

With more than 3000 customers and 120 billion API calls each month reliability is a must at cloud-based search company Algolia. We spoke with Anthony Seure a Site Reliability Engineer at Algolia about how sleep was the main constraint when the processing pipeline was redesigned. By keeping the system running the Site Reliability Engineers, or Sleep Reinforcement Engineers (SREs) as they preferred to be known, made sure the whole system was highly reliable. As much as the team would have like to call forth Harry Potter’s magic it relied on crafty use of multiple cloud services and removing single points of failure.

Keeping containers together in a scale out world with Kubernetes

Are you ready for a world of apps run in containers? Following his presentation at TechSummit Amsterdam we spoke with NetApp Solutions Architect Christopher Madden about deploying stateful apps in containers with Kubernetes. App owners build stateful apps which must be underpinned by infrastructure resources like persistent volumes and storage classes. If your stateful app is a single instance database the basics might be enough, but with a scale-out database architecture application-specific “glue” is needed to manage this gracefully. There are a few approaches to providing this glue by deploying a scale out database on Kubernetes using Trident, NetApp’s dynamic storage provisioning tool.

Taking TechSummit Online

Oscar Wilde once wrote that “The only thing to do with good advice is pass it on. It is never any use to oneself.” This is quite similar to the famous words of the great Jedi Master Yoda, “Always pass on what you have learned.” While one of these figures is imaginary, and the other consumed by imagination, their respective words reflect one of the founding ideals of TechSummit, that when knowledge is shared it becomes a way of bringing people together to advance the field and create common understanding.
