Overview of this book

<p><span id="description" class="sugar_field">Docker has been a game-changer when it comes to virtualization – it has now grown to become a key driver of innovation beyond system administration, having an impact on the world of web development and more. But how can you make sure you’re keeping up with the innovations that it’s driving? How can you be sure you’re using it to its full potential? Mastering Docker shows you how – it not only demonstrates how to use Docker more effectively, it also helps you rethink and reimagine what’s possible with Docker.</span></p> <p><span class="sugar_field"><span id="description" class="sugar_field"> Covering best practices to make sure you’re confident with and the basics, such as building, managing and storing containers, before diving deeper into Docker security, you’ll find everything you need to help you extend and integrate Docker in new and innovative ways. You’ll learn how to take greater control over your containers using some of Docker’s most sophisticated and useful tools, such as Docker compose and Docker swarm, before bringing together everything you already know and have learned to put your containers into production and monitor them for safety and performance.</span></span></p> <p><span class="sugar_field"><span class="sugar_field"><span id="description" class="sugar_field"> Beyond this, you’ll also explore even more advanced strategies, as you learn how to extend and integrate Docker with cloud platforms such as Heroku and OpenStack, and how tools such as Kubernetes can improve the way you manage large-scale container orchestration. With further guidance on how you can use configuration management tools such as Puppet, Chef and PowerShell, by the end of the book you’ll have a broad and detailed sense of exactly what’s possible with Docker – and how seamlessly it fits with a range of other platforms and tools.</span></span></span></p>

Back to CONTAINERS


We jump back to the CONTAINERS section where we saw all our containers. We can also click on the magnifying glass on the right-hand side of each container to get pulled to the following screen:

We can then get information on that running container and manipulate it. We can stop, restart, or destroy (or remove) it. We can also see information on it such as the command that it's running, its port, its IP address, and its node name.

Clicking on the Stats button, we can see information pertaining to the running container such as the CPU, memory, and network information.

Clicking on the Logs button will show you everything that is going on with the container. In this case, the container is polling consult for new information ever so often.

Now, the Console button is interesting. It will allow you to actually run a command against the container and provide the output from that command.

There are other ways to manipulate these containers as well. We will go back to the CONTAINERS...
