Course Overview
Containerization has become a critical DevOps skill as more organizations move to cloud-native development. Among companies with at least 1,000 hosts, 47% now run Docker in full production. Docker has become the standard for building, shipping, and running applications in lightweight containers, helping teams simplify deployment and improve scalability.
The Docker Containerization Essentials course provides a comprehensive introduction to Docker containerization essentials. You will gain hands-on experience creating and managing containers using the Docker Engine and Docker Hub, working with container images, and applying best practices in container image design. Through practical labs, you will build Docker images, deploy containers, configure container networking and storage, and manage the container lifecycle with confidence.
