Docker Logging: How Do Logs Work With Docker Containers?

Docker containers are a great way to create lightweight, portable, and self-contained application environments. Logging is critical for every application since it gives valuable information for troubleshooting, evaluating performance issues, and drawing an overall picture of the behavior of your architecture. This article presents a thorough tutorial covering all you need to know to start with Docker logging. It also provides some recommended practices for optimizing the logs of your containerized apps.

7 Things to Consider To Build Scalable Web Applications

Suppose you've built a web application and started getting a few customers. After some feedback and iterations, you are ready with a product that people want. From now, your application is drawing attention to more and more users, with more and more requests per minute (RPM). Suddenly, a wave of new people use your app, and at one point, they can't use it anymore. While testing your app, you realize that it's working correctly. So what happened? You are simply facing a scalability problem.

Managed Kubernetes Comparison: EKS vs GKE

Kubernetes is changing the tech space as it becomes increasingly prominent across various industries and environments. Kubernetes can now be found in on-premise data centers, cloud environments, edge solutions, and even space. As a container orchestration system, Kubernetes automatically manages the availability and scalability of your containerized applications. Its architecture consists of various planes that make up what is known as a cluster.

Path To Rancher Desktop 1.0.0

Rancher Desktop has been in development for just over a year with the open question: when do we have a 1.0.0 stable release? Along the way the scope has expanded, it was ported to run in more places and the development team has grown. All of this happened as we worked out if Rancher Desktop would be useful for people, what features people want to use and what are good ways to build it. We are finally ready to answer that 1.0.0 question.

DigitalOcean and the developer experience for Kubernetes

DigitalOcean, or DO, brands itself as the “developer cloud,” and it’s no secret that it has a strong mind-share among developers, especially because of factors such as simple UI, performance, structured documentation, a robust community ecosystem, and last but not least, the affordable pricing. As developers started adopting microservices as the architecture of choice for their applications, DO responded quickly and launched their Managed Kubernetes offering, labeled DOKS.

Learning the tricks of Grafana Loki for distributed logging at scale in a Kubernetes environment

Logging can provide immense detail when used well, or it can become a firehose and take hours to trawl through. The team supporting the Kubernetes platform at Civo needed a solution that was simple and performant and could be queried in ways to help and not hinder them In this talk, Civo SRE Anaïs Urlichs and Principal Engineer Alex Jones will illustrate how Loki was chosen and brought into the organization to empower engineers. Integrating with Prometheus and Grafana dashboards, Loki has allowed engineers to filter for precise information that helps them debug quicker.

Extending Panorama's firewall address groups into your Kubernetes cluster using Calico NetworkSets

When deploying cloud-native applications to a hybrid and multi-cloud environment that is protected by traditional perimeter-based firewalls, such as Palo Alto Networks (PAN) Panorama, you need to work within the confines of your existing IT security architecture. For applications that communicate with external resources outside the Kubernetes cluster, a traditional firewall is typically going to be part of that communication.

Five tricks for logging at scale in a Kubernetes environment with Grafana Loki

Legacy logging solutions simply couldn’t keep up with the complex, hyperconverged regional infrastructure at Civo, a Kubernetes service provider that enables users to launch k8s clusters within 90 seconds. “With our infrastructure and application deployment getting more complex and more distributed, we needed our logging solution and our entire observability stack to scale up with our needs,” said Anaïs Urlichs, Site Reliability Engineer at Civo.

Fairwinds: Kubernetes Guardrails and Governance to Enable Developers and Reduce Risk

Customers of both PagerDuty and Fairwinds Insights can generate and customize PagerDuty incidents for critical issues in their Kubernetes clusters. This capability includes over 100 checks that have been built-in to Fairwinds Insights for things like container vulnerabilities, insecure workload configurations, runtime security events, and resource usage—as well as custom user-defined policies for compliance and internal requirements.
