Docker Advanced Course

Course description:

Docker Advanced course covers advanced topics related to working with Docker Swarm clusters and Docker images. This course is a deep dive into the underlying kernel technologies that make containers possible, working with secrets, container networking, security, advanced node management, availability, monitoring and logging, collecting metrics, multi-stage builds and automated builds.

Target audience:

• DevOps engineers
• Linux system administrators
• Systems design engineers
• Architects

Prerequisites for Docker Advanced Course:

• Basic knowledge of Docker
• Interacting with Docker containers from the command line (start and stop containers, attach, exec, etc.)
• Working with Docker bridge networks and volumes
• Creating Docker images (Dockerfiles)

Nice to have:

Recommended training: Docker Fundamentals course
