Advanced Docker Training
This advanced Docker course teaches attendees to orchestrate multi-container deployments, fortify their container security, and streamline image size for optimized workflows. They will gain a strong foundation in container orchestration tools like Docker Swarm and Kubernetes.
Docker makes setting up development environments and deploying applications easier than ever. However, many of its best features are under-utilized or misunderstood. Features such as multi-stage Dockerfiles, persistent storage volumes, and multi-container application capabilities are mistakenly passed over when the goal is to - “just get something running!” This Docker course addresses these issues and more.
