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 […]

Running Elasticsearch in Docker containers 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 […]

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 […]

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 […]

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 […]
