About the course
Our hands-on, instructor-led Advanced Docker training course explores Docker Compose, Docker Machine, and Docker Swarm in detail.
This workshop aims to take your existing skills with Docker to the next level - you'll be guided by a containerisation expert in the use of key Docker components to scale your architecture securely, and with high performance.
Online and in-house face-to-face options are available - as part of a wider customised training programme, or as a standalone workshop, on-site at your offices or at one of many flexible meeting spaces in the UK and around the World.

Docker Compose Deep Dive
Introduction to Docker Compose:
What is Docker Compose and when to use it?
Benefits of Compose for multi-container applications.
Compose use cases (development, testing, production).
Compose Fundamentals:
docker-compose.yml structure and syntax (all versions).
Defining services, networks, volumes, and other resources.
Environment variables and .env files.
Building images within Compose.
Service Lifecycle Management:
up, down, start, stop, restart, pause, unpause, kill.
ps, logs, exec, port, top.
Advanced Compose Features:
Health checks and dependencies.
Networking and port mapping.
Volumes and data persistence.
Resource limits (CPU, memory).
Logging drivers.
Secrets management.
Extending and overriding Compose files.
Compose in Different Environments:
Using Compose for local development.
Deploying with Compose to various platforms (e.g., Docker Swarm, Kubernetes - briefly mention alternatives).
Orchestration with Docker Swarm
Introduction to Docker Swarm:
What is Docker Swarm and its architecture?
Swarm vs. Compose vs. Kubernetes (brief comparison).
Key concepts: nodes, services, tasks, ingress networking.
Setting up a Swarm Cluster:
Initializing a Swarm (single and multi-node).
Adding and managing worker nodes.
Securing a Swarm.
Deploying and Managing Services in Swarm:
Creating services.
Scaling services.
Updating services (rolling updates).
Removing services.
Service discovery and load balancing.
Advanced Swarm Features:
Overlay networks.
Routing mesh.
Secrets management.
Configs.
Global vs. replicated services.
Draining nodes.
Autolocking.
Monitoring and Troubleshooting Swarm:
Inspecting Swarm and service state.
Logging and debugging.
Using tools like Portainer (or alternatives) for management.
Compose and Swarm Integration
Deploying with Compose to Swarm:
docker-compose.yml for Swarm deployments (using the deploy key).
Understanding the deploy section: replicas, placement constraints, update configuration, resources, etc.
Building and Deploying a Multi-Service Application to Swarm:
Real-world application example.
Defining services, networks, volumes, and secrets.
Deploying, scaling, and updating the application in Swarm.
Advanced Compose and Swarm Deployment Strategies:
Rolling updates and rollbacks.
Managing persistent data in Swarm.
Networking considerations for multi-service applications.
Alternative Orchestration Tools (Brief Overview):
A brief overview of Kubernetes and Nomad, highlighting their differences and similarities with Docker Swarm. This section should not be a deep dive but rather an awareness section.
Advanced Docker Concepts and Best Practices
Docker Networking Deep Dive:
Bridge, host, overlay, macvlan networks.
Custom network creation and management.
DNS and service discovery.
Docker Volumes and Data Management:
Volume types: bind mounts, Docker-managed volumes.
Volume plugins.
Backing up and restoring volumes.
Docker Security Best Practices:
Image security.
Container security.
Swarm security.
Using security scanning tools.
Docker Performance Tuning:
Resource limits.
Storage drivers.
Networking performance.
Multi-platform Images
Building for different architectures
Manifest lists.
