2016 Year in Review: Monitoring and Logging Highlights
2017 is almost here and, like last year, we thought we’d share how 2016 went for us. We remain committed to be your “one-stop shop” for all things Elasticsearch and Solr: from Consulting, Production Support, and Training, to complementing that […]
Making Elasticsearch in Docker Swarm Elastic
Running on Elasticsearch on Docker sounds like a natural fit – both technologies promise elasticity. However, running a truly elastic Elasticsearch cluster on Docker Swarm became somewhat difficult with Docker 1.12 in Swarm mode. Why? Since Elasticsearch gave up on […]
Docker Swarm Lessons from Swarm3K
This is a guest post by Prof. Chanwit Kaewkasi, Docker Captain who organized Swarm3K – the largest Docker Swarm cluster to date. Swarm3K Review Swarm3K was the second collaborative project trying to form a very large Docker cluster with the […]
Taming SwarmZilla: 150k Containers in 3K+ Docker Swarm Nodes
SwarmZilla/swarm3k by Docker Captain Chanwit Kaewkasi is a unique community project/event aimed at launching a Docker Swarm cluster with 3000+ community-sponsored nodes. The previous project – Swarm2k – successfully demonstrated a 2000+ node Swarm cluster with only 3 Swarm managers […]
Docker “Swarm Mode”: Full Cluster Monitoring & Logging with 1 Command
Until recently, automating the deployment of Performance Monitoring agents in Docker Swarm clusters was challenging because monitoring agents had to be deployed to each cluster node and the previous Docker releases (<Docker engine v1.12 / Docker Swarm 1.2.4) had no […]
Rancher Monitoring and Logging Support
Rancher is one of the few “container only” operating systems and it evolved into an excellent orchestration tool for containers, competing e.g. with CoreOS. It supports several types of schedulers such as its own “Cattle” scheduler, as well as Kubernetes, […]
Open Source Docker Monitoring & Logging
Pets ⇒ Cattle ⇒ Orchestration Docker is growing by leaps and bounds, and along with it its ecosystem. Being light, the predominant container deployment involves running just a single app or service inside each container. Most software products and services […]
