Introducing MinIO Support in Sematext

Sematext Logs is a Log Management-as-a-service. Think of it as your own central location for logs in the cloud. If you prefer or need to keep logs in your own environment instead of shipping it to the cloud Sematext Enterprise, designed to run on your own infrastructure, makes that possible. You can collect logs from any part of your software stack or infrastructure, IoT devices, network hardware, and much more.

Kubernetes GitOps with Rancher Continuous Delivery

As the number of Kubernetes clusters under management increases, application owners and cluster operators need a programmatic way to approach cluster management. Rancher CD solves this by creating a git driven engine for applying cluster changes. Declarative code is stored in a git repo. As changes are committed to the repo, linked clusters are automatically updated. Gitops keeps all your clusters consistent, version controlled, and reduces the administrative burden as you scale.

Announcing Harvester: Open Source Hyperconverged Infrastructure (HCI) Software

Today, I am excited to announce project Harvester, open source hyperconverged infrastructure (HCI) software built using Kubernetes. Harvester provides fully integrated virtualization and storage capabilities on bare-metal servers. No Kubernetes knowledge is required to use Harvester. In the past few years, we’ve seen many attempts to bring VM management into container platforms, including our own RancherVM, and other solutions like KubeVirt and Virtlet.

An Open Source Prometheus Tutorial for System and Docker Monitoring

Prometheus is an essential element in DevOps. It has one of the largest contributor communities in the open source world and is the favorite database for time-series metrics data. It is also part of Logz.io’s complete observability package, which integrates open source grafana, Jaeger, and ELK Stack into one platform. It’s a favorite for system and container monitoring. This tutorial will show you how Prometheus works with Docker and your local machine.

Automated, Simplified DNS Troubleshooting for Kubernetes: Only in Calico Enterprise

The Domain Name System (DNS) is a naming system for computers, services, or other resources connected to the Internet or a private network. DNS translates domain names to the numerical IP addresses needed for locating and identifying computer services and devices. For decades It’s been an essential component of the Internet. It’s an essential part of Kubernetes as well, and is used to determine how workloads connect to Kubernetes services as well as resources outside the cluster.

Simplifying Storage in Kubernetes

On December 9th, 2020, I had the pleasure of speaking with two great minds on the topic of simplifying storage in Kubernetes. Alex Chircop is the Founder and CEO at StorageOS (https://storageos.com), and Bruno Andrade is the Founder and CEO at Shipa (https://www.shipa.io). The full recording of this discussion is below. Here is a summary of what we discussed: Simplify Deploying and Operating Stateful Applications within Kubernetes

Use Amazon ECR Public and EKS-D to deploy LTS Docker Images

It’s re:invent season already, and we had exciting news to announce with Amazon this year. With all these remote sessions, what’s better than a quick lab to play with the new stuff? It’s starting to feel like Christmas already! We’re going to kill two birds with one stone (just an idiom, keep reading) and experiment with two of our latest announcements.

Enabling Secure Kubernetes Multi-Tenancy with Calico Enterprise

When you have different teams interacting with a Kubernetes cluster you need to think about the security, privacy, and observability challenges associated with multi-tenancy: How to provide each team with access to the specific resources they need, in a way that allows the team to be agile, without risking impacting other teams? In this session, we’ll explore the Kubernetes multi tenancy concepts and design patterns needed for successful enablement of multi-tenancy within your Kubernetes clusters using key capabilities of Calico Enterprise.
