Docker Swarm advanced (3 days)

The training includes the topics from "Docker foundations" and "Docker Swarm intermediate" courses. Aims to give an exhaustive overview on Docker and the Docker Swarm orchestrator, including concepts as Docker Stacks, scalability, troubleshooting and security issues.

Results

By the end of the course, participants will be able to:

• Setup docker
• Build and run docker images
• Use docker-compose to automate some tasks that could be cumbersome and error prone when one via commandline.
• Confidently create Docker Swarm clusters and manage the underlying nodes and services
• Perform basic troubleshooting by inspecting logs and service statuses
• Understanding of how Mesh-Rouging and DNSRR works
• Deploy services selectively distributing them across the nodes in the cluster
• Understanding security implications of running containers with advanced privileges

Requirements:

• A general idea of virtualization or container software
