This course is intended for any IT professionals who is familiar with basic Docker concepts and want to learn how to deploy Docker for real-world applications.
In this course we will present the inner workings of how to run containerized applications spanning multiple Docker hosts.
We will discuss orchestration and scheduling.
We will present Docker Swarm and see it in action on an actual microservices architecture. We will give recipes to implement cleanly various ops tasks including logging, backups, monitoring, and more.
Course Objectives
After completing this course, students will be able to:
• Initializing, extending, and putting the Docker Swarm to work.
• Configuring Prometheus and Grafana for Monitoring your Swarm
