This workshop is based on the material published in The DevOps 2.1 Toolkit: Building, testing, deploying, and monitoring services inside Docker Swarm clusters.
The workshop will go through the whole microservices development lifecycle. We’ll start from the very beginning and define and design architecture. From there on we’ll move from requirements, technological choices and development environment setup, through coding and testing all the way until the final deployment to production. We won’t stop there. Once our new services are up and running we’ll see how to maintain them, scale them depending on resource utilization and response time, and recover them in case of failures. We’ll try to balance the need for creative manual work and the need to automate as much of the process as possible.
The goal will be to design a fully automated continuous deployment (CDP) pipeline. We’ll see how microservices fit into CDP and immutable containers concepts and why the best results are obtained when those three are combined into one unique framework.
During the workshop we’ll explore tools like Docker, Docker Swarm, Docker Compose, Jenkins, HAProxy, and a few others.
We'll explore the practices and tools required to run a Swarm cluster. We'll go beyond a simple deployment. We'll explore how to create a continuous deployment process. We'll set up multiple clusters. One will be dedicated to testing and the other for production. We'll see how to accomplish zero-downtime deployments, what to do in case of a failover, how to run services at scale, how to monitor the systems, and how to make it heal itself. We'll explore the processes that will allow us to run the clusters on a laptop as well as on different cloud providers.
