The DevOps 2.1 Toolkit: Docker Swarm

By: Viktor Farcic

Overview of this book

Viktor Farcic's latest book, The DevOps 2.1 Toolkit: Docker Swarm, takes you deeper into one of the major subjects of his international best seller, The DevOps 2.0 Toolkit, and shows you how to successfully integrate Docker Swarm into your DevOps toolset. Viktor shares with you his expert knowledge in all aspects of building, testing, deploying, and monitoring services inside Docker Swarm clusters. You'll go through all the tools required for running a cluster. You'll travel through the whole process with clusters running locally on a laptop. Once you're confident with that outcome, Viktor shows you how to translate your experience to different hosting providers like AWS, Azure, and DigitalOcean. Viktor has updated his DevOps 2.0 framework in this book to use the latest and greatest features and techniques introduced in Docker. We'll go through many practices and even more tools. While there will be a lot of theory, this is a hands-on book. You won't be able to complete it by reading it on the metro on your way to work. You'll have to read this book while in front of the computer and get your hands dirty.

Using Grafana to create dashboards


Prometheus offers a dashboard builder called PromDash (https://github.com/prometheus/promdash). However, it is deprecated for Grafana, so we won't consider it as worthy of running inside our cluster.

Grafana (http://grafana.org/) is one of the leading tools for querying and visualization of time series metrics. It features interactive and editable graphs and supports multiple data sources. Graphite, Elasticsearch, InfluxDB, OpenTSDB, KairosDB, and, most importantly, Prometheus are supported out of the box. If that's not enough, additional data sources can be added through plugins. Grafana is truly a rich UI that has established itself as a market leader. Best of all, it's free.

Let's create a grafana service:

docker service create \
    --name grafana \
    --network proxy \
    -p 3000:3000 \
    grafana/grafana:3.1.1

A few moments later, the status of the replica should be running:

docker service ps grafana

The output of the service ps command is as follows...
