Introducing Docker 1.13

Today we’re releasing Docker 1.13 with lots of new features, improvements and fixes to help Docker users with New Year’s resolutions to build more and better container apps. Docker 1.13 builds on and improves Docker swarm mode introduced in Docker 1.12 and has lots of other fixes. Read on for Docker 1.13 highlights. Use compose-files to deploy swarm mode services Docker 1.13 adds Compose-file support to the `docker stack deploy` command so that services can be deployed using a `docker-compose.yml` file directly. Powering this is a major effort to extend the swarm service API to make it more flexible and useful. Benefits include: Specifying the number of desired instances for each service Rolling update policies Service constraints Deploying a multi-host, multi-service stack is now as simple as: docker stack deploy –compose-file=docker-compose.yml my_stack Improved CLI backwards compatibility Ever been bitten by the dreaded Error Continue reading…

Docker & Prometheus Joint Holiday Meetup Recap

Last Wednesday we had our 52nd meetup at Docker HQ, but this time we joined forces with the Prometheus user group to host a mega-meetup! There was a great turnout and members were excited to see the talks on using Docker with Prometheus, OpenTracing and the new Docker playground; play-with-docker. First up was Stephen Day, a Senior Software Engineer at Docker, who presented a talk entitled, ‘The History of Metrics According to Me’. Stephen believes that metrics and monitoring should be built into every piece of software we create, from the ground up. By solving the hard parts of application metrics in Docker, he thinks it becomes more likely that metrics are a part of your services from the start. See the video of his intriguing talk and slides below. ‘The History of Metrics According to me’ by Stephen Day Continue reading…

#SwarmWeek: Realtime Cluster Monitoring with Docker Swarm and Riemann

Lately I’ve become fascinated with Riemann, a piece of software written in Clojure for the purpose of supervising the health of distributed systems. Created by Kyle Kingsbury (a.k.a. aphyr) of Jepsen fame, Riemann is a powerful tool for montioring, processing, and responding to information from your cattle herd.

Ecosystem Technology Partner (ETP) Program: Monitoring

Monitoring solutions for Docker containers Software applications are changing, and by extension, so are the requirements of application monitoring systems. Docker enables developers to iterate faster with software architectures consisting of many small and isolated microservices. This poses a challenge to traditional monitoring solutions as the target processes are no longer statically allocated or tied to particular hosts. Monitoring systems are now expected to track ephemeral and rapidly scaling sets of containers. Thankfully, the Docker Engine exposes APIs for container metadata, lifecycle events, and key performance metrics (Docker 1.5+) that enable the development of robust monitoring solutions. Today we are highlighting a number of these solutions that have demonstrated quality integrations with Docker APIs and provide a compelling user experience.

Docker Tutorial 8 – Troubleshooting with Sysdig

This is a casual Docker tutorial series. We will start out first with very simple sessions on how to install and use the docker run command. In future videos we will hit more advanced topics.
