Training & Certifications

Docker is an extremely powerful tool for running and managing containers. Currently, Docker is the industry-leading container runtime platform and offers a colossal number of features revolving around container management, plus orchestration.

This program serves as preparation for learners who seek to pass the Docker Certified Associate certification exam offered by Docker. Ultimately, the certification exam aims to validate one’s skills as a Docker practitioner. In this course, we will dissect both the concepts and objectives needed to use Docker effectively. Learners will also uncover how to leverage core features contained within Docker Community Edition (DCE), as well as the additional features offered through Docker Enterprise Edition (DEE).

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

  1. Run containerized applications from pre-existing images stored in a centralized registry
  2. Deploy images across the cluster
  3. Install, maintain, and operate the Docker platform
  4. Triage issue reports from stakeholders and resolve
  5. Standup new Docker environments and perform general maintenance and configuration
  6. Migrate traditional applications to containers
  7. Configure and troubleshoot Docker engine

This program is suitable for anyone who wants to learn about docker.

This program is a 5-day of intensive training class.

There are no prerequisites for this program.

At the end of the program, the participants will be assessed by Multimatics.

Certificate of Completion will be awarded upon completion of training from Multimatics.
