Managing Docker at scale is the next challenge facing IT. This course, Docker Swarm: Native Docker Clustering, will teach you everything you need to know about Docker Swarm, the native solution for managing Docker environments at scale. First, you’ll learn how to build highly available, production-grade Swarm clusters. You’ll also cover how to secure them with TLS and certificates. Finally, you’ll discover how Docker Swarm is used behind the scenes by other technologies such as Docker Datacenter and Universal Control Plane. By the end of this course, you’ll have a foundational knowledge of Docker Swarm and you’ll know how to use it to manage Docker’s infrastructure.
This course is geared towards more technical folks. If you are not sure what Docker is or are new to Docker, please take my free class, Docker Essentials, which you can find by searching for Geoffrey Emery Docker Essentials. If you have some or limited experience with Docker but understand it nonetheless, try my course Docker for Developers, which you can find by searching for Geoffrey Emery Docker for Developers. If you have a good understanding of Docker but are new to Swarm or clustering Docker, then this is the course for you and it will teach you everything you need to know.
In this course you will learn about:
1. What Swarm is and why it is great.
2. How to build high availability infrastructure needed for critical applications
3. How to Building Your Swarm Cluster
5. How to use topline security to secure your Swarm Cluster
6. How to deploy your application to a Swarm Cluster
7. How to filter and sort your nodes for optimal deployment
8. How you can use Swarm to integrate with other tools.
By the end of the course you will have everything at your disposal that you need to deploy a Swarm Cluster to AWS.
Course Overview
Course Introduction and Exercise FIles
In this section we will go over how to use the exercise files for Docker Swarm from beginner to advanced.
Introducing Swarm
Building Your Infrastructure
Introduction to the chapter Building Your Infrastructure in High Availability
In this section we are going define what we need to do to build a high availability cluster in AWS
In this section we are going to summarize what it takes to build your infrastructure in a high availability format.
Building a Swarm Cluster in the real world
In this section we will review what we need to do to build a high availability swarm cluster int he real world.
In this section we will build a High Availability Discovery Service
In this section we will build a High Availability Swarm Managers
Now that we have all of manager services done lets add some nodes so we can deploy some real containers.
We learned a tone this chapter lets summarize and bring all the paces together.
Filtering And Scheduling
In this the introduction to Filtering and Scheduling we will go over the chapter agenda
In the chapter on scheduling overview we will go over the different types of scheduling algorithms Docker Swarm provides.
In the chapter Scheduling with RAM reservations we will learn how to use the RAM and CPU definitions to help the scheduler place nodes in the cluster.
Dockers Swarm Affinity Filters allow you to place containers next to a container that already exists or on a node where a image of the container has already been pulled. We will review how to set this up in the is section.
Dockers Swarm Standard Constraint Scheduler allows you to schedule your nodes from information received from the Docker Info Commands. This section will teach you how to work with Affinity filters.
Custom Constraints are my personal favorite Docker Swarm Scheduler. It allows us to schedule containers against self made tags. Truly awesome.
In the section we will review the chapter and go over the highlights of Docker Swarm Scheduling.

This is a post about the differences between the networking drivers and their use cases
Whether you're developing a microservices-oriented software application, or looking for a better way to distribute a traditional, monolithic application, Docker Compose is a key tool in the developer's arsenal. Formerly known as Fig, Docker Inc. acquired the software, when its creators joined Docker in July 2014, barely a month after the release of the first supported version of Docker. Since then, Fig has evolved into Docker Compose, has been considerably enhanced, and is widely used by Docker adopters in their development practices.
In this quick start, a Docker Swarm cluster is deployed using the Azure CLI. A multi-container application consisting of web front end and a Redis instance is then deployed and run on the cluster. Once completed, the application is accessible over the internet.+
