In HAProxy Data Plane API version 2.6, we continued the effort of expanding support for HAProxy configuration keywords, as this has been the priority with this release cycle, and it will be in the next one too to meet our goal of achieving complete feature parity with both the HAProxy configuration and Runtime API. This will enable you to use HAProxy Data Plane API for configuring HAProxy without any gaps in functionality.
Distributed systems open us up to myriad complexities due to their microservices architecture. There are always little problems that arise in the system. Therefore, engineering teams must be able to determine how to prioritize the challenges. Viewing logs and metrics of such systems enables engineers to know the shared state of the system components, thereby informing the decision-making on what challenge needs to be solved most immediately.
What if there was a way to deploy a new feature into production — and not actually turn it on until you’re ready? There is! These tools are called feature flags (or feature toggles or flippers, depending on whom you ask). Feature flags are a powerful way to fine-tune your control over which features are enabled within a software deployment. Of course, feature flags aren’t the right solution in all cases.
With ARM based dev machines and servers becoming more common, it is become increasingly important to build Docker images that support multiple architectures. This guide will show you how to build these Docker images on any machine of your choosing.
Docker is a platform as a service product. With Docker, you can easily deploy applications into Docker containers. Containers are software "packages" that bundle together an application's source code with its libraries, configurations, and dependencies. This helps software run more consistently on different machines. To use Docker containers, you need to understand how Docker networking works. Below, we'll answer the question: "what is Docker network host?". We'll also take a look to see how it works.
Today we’re releasing fully redesigned Slack and Command Center experiences for FireHydrant so anyone on your team can intuitively navigate the incident response process — in the app or on the web. There are many things you can do ahead of an incident to help things run smoothly: design and document your process, automate predictable steps, train the team, and run drills.
