Overview of this book

<p>Docker allows you to create a robust and resilient environment to generate portable, composable, scalable, and stable application containers.</p> <p>The book starts by installing the core Docker Engine on MacOS, Windows 10 and Linux desktops. We will then define multi-container applications and understand the advantages of using containers locally. Once this is done, we will deploy containers on a single Docker host which is publicly accessible. Furthermore, we will learn how to deploy and configure a Docker Swarm cluster and explore networking and storage third-party plugins to extend the core Docker functionality. Towards the end, the book will demonstrate how to monitor and troubleshoot day-to-day problems in addition to various real world examples of container deployments.</p>

Chapter 6. Troubleshooting and Monitoring

In this chapter, we are going to look at commands which will come in useful when troubleshooting your containers, all the commands we will look at are part of the core Docker Engine, we will also look at a way by which you can debug your Dockerfiles.

Once we have finished with the Troubleshooting commands, we will look at how we can monitor our containers using cAdvisor with a Prometheus backend fronted by a Grafana dashboard – don't worry, it is not as complicated as it sounds.

Note

As we are going to be exposing services, some using default credentials I would recommend that you use your local Docker installation for this chapter.
