Overview of this book

No doubt Docker Containers are the future of highly-scalable software systems and have cost and runtime efficient supporting infrastructure. But learning it might look complex as it comes with many technicalities. This is where The Docker Workshop will help you. Through this workshop, you’ll quickly learn how to work with containers and Docker with the help of practical activities.? The workshop starts with Docker containers, enabling you to understand how it works. You’ll run third party Docker images and also create your own images using Dockerfiles and multi-stage Dockerfiles. Next, you’ll create environments for Docker images, and expedite your deployment and testing process with Continuous Integration. Moving ahead, you’ll tap into interesting topics and learn how to implement production-ready environments using Docker Swarm. You’ll also apply best practices to secure Docker images and to ensure that production environments are running at maximum capacity. Towards the end, you’ll gather skills to successfully move Docker from development to testing, and then into production. While doing so, you’ll learn how to troubleshoot issues, clear up resource bottlenecks and optimize the performance of services. By the end of this workshop, you’ll be able to utilize Docker containers in real-world use cases.

Preface

Introduction

Whenever something goes wrong with our running applications or service, the first thing we usually look for in our application logs is a clue as to what is causing the issue. So, it becomes important to understand how you'll be collecting logs and monitoring log events for your project.

As we implement a microservice architecture with Docker, it becomes more important to ensure we are able to see the logs our applications and containers are generating. As the number of containers and services grows, trying to access each running container individually becomes increasingly unwieldy as a means of troubleshooting any issues that arise. For scalable applications, where they scale up and down depending on demand, it may become increasingly difficult to track log errors across multiple containers.

Ensuring we have a proper log monitoring strategy in place will help us troubleshoot our applications and ensure our services are running at their optimum efficiency....
