What Is Etcd and How Do You Set Up an Etcd Cluster?
Etcd is an open-source distributed key-value store created by the CoreOS team, now managed by the Cloud Native Computing Foundation. It is pronounced “et-cee-dee”, making reference to distributing the Unix “/etc” directory, where most global configuration files live, across multiple machines. It serves as the backbone of many distributed systems, providing a reliable way for storing data across a cluster of servers.
Leveraging Service Accounts for Label-based Security
One of the key Kubernetes security concepts is that workload identity is tied back to information that the orchestrator has. The orchestrator is actually the authoritative entity for what the actual workloads are in the platform. Kubernetes uses labels to select objects and to identify collections of objects that satisfy certain conditions. We, and others in the Kubernetes networking space, often talk about using Kubernetes ‘labels’ as identity bearers.
OpsRamp Delivers Greater Service Centricity, Expanded AIOps and Cloud Native Monitoring
OpsRamp, the service-centric AIOps software-as-a-service (SaaS) platform for the hybrid enterprise, today announced new topology maps, enhanced artificial intelligence for IT operatzions (AIOps) features and new monitoring capabilities for cloud native workloads.
Sysdig Monitor: Overview of Dashboards
Overview of how metrics are visualized in Sysdig Monitor through dashboards and panels in the Explore feature of the platform, looking at varying timescales and different groupings based on Kubernetes namespaces as well as segmenting data in panels.
Sysdig Monitor: Building Dashboards
Review of the dashboards feature of Sysdig Monitor, and understanding how a dashboard can quickly be created and customized based on pre-defined assets available out of the box, setting scoping to the required namespace, deployment, pod or host/container in the environment as well as manipulating the layout of the dashboard.
Sysdig Monitor: Customizing Panels
Reviewing components of dashboards in Sysdig Monitor known as panels, exploring methods of visualizing metrics through different panel types - line graphs, bar charts, topology views and lists.
Sysdig Monitor: Sharing Dashboards & Groupings
Review of how to save and share customized groupings and dashboards in Sysdig Monitor with other team members, produce public URLs for dashboards to make dashboards easily available for non-Sysdig users and copy panels from the Explore view to a new or existing dashboard for easy reference.
Image Management & Mutability in Docker and Kubernetes
Kubernetes is a fantastic tool for building large containerised software systems in a manner that is both resilient and scalable. But the architecture and design of Kubernetes has evolved over time, and there are some areas that could do with tweaking or rethinking. This post digs into some issues related to how image tags are handled in Kubernetes and how they are treated differently in plain Docker.
Sysdig Monitor: Overview of Groupings
Review of how an environment is represented in Sysdig Monitor, focusing on the the power of Sysdig's ContainerVision and ServiceVision - the ability to dynamically group physical hosts with a service orientated view from the orchestration platform (such as Kubernetes) and cloud provider, all auto-detected out of the box.
