Deploying Containerized Applications Technical Overview

In this this official Red Hat® training course, Jim Rigsbee, a curriculum architect for Red Hat Training, will introduce you to container technology using Docker running on Red Hat Enterprise Linux.

Docker has become the de facto standard for defining and running containers in the Linux® operating system. Kubernetes is Red Hat's choice for container orchestration. OpenShift, built upon Docker, Kubernetes, and other open source software projects, provides Platform-as-a-Service (PaaS) for the ultimate in deploying applications within containers.

Through short lectures and in-depth demonstrations, we will explore container technology and deploy a single three-tiered Java EE application using several container-based platforms, including Docker, Kubernetes, and OpenShift Enterprise by Red Hat.

👩‍🏫 **Course Overview:** The course provides a solid overview of Docker, Kubernetes, and OpenShift, which are essential technologies for containerization and orchestration. The content is well-contained, offering a quick look at Red Hat's OpenShift. The presentation style varies among instructors, with some delivering explanations at a pace that may require viewers to follow along closely. **Pros:** - **Comprehensive Content:** The course covers the basics of Docker, Kubernetes, and OpenShift effectively, providing a good foundation for learners. - **Clear Explanations:** The instructors explain concepts well, with many providing clear and concise information. - **Real-world Examples:** The use of practical examples to illustrate points is appreciated, making the course more engaging and easier to understand. - **Good Video Quality:** The quality of the videos is reported to be high, which enhances the learning experience. - **Engaging Presentation:** Some instructors keep the audience engaged by presenting material in an engaging manner. **Cons:** - **Pacing Issues:** A few reviews mention that the presenters could be more rapid in their explanations, which might be beneficial for a faster understanding of the content. - **Lack of Advanced Content:** The course seems to be more of an introduction rather than a deep dive into advanced topics, which may leave experienced users wanting more detailed information. - **Prerequisites Not Clearly Stated:** Some users feel that there are prerequisites for understanding the full scope of the course, which should be made clearer to potential students. - **Missing Practical Resources:** The absence of linked resources and the lack of setup instructions for the environment could be significant limitations for hands-on learners. - **Speed of Presenter:** One review points out that the instructor's pace, while explaining notes, led to some mistakes during command typing, suggesting that a Subject Matter Expert (SME) might provide more proficient teaching. **Suggestions from Learners:** - **Additional Lectures:** Some learners recommend adding more lectures with additional explanation and examples to the course. - **Use of Visuals:** It is suggested that explanations could be enhanced with figures, diagrams, and pictorial representations for better comprehension, especially for newcomers. - **Sequential Learning Path:** A recommendation for learners to watch a course on Docker before this course to gain more from the later content. - **Further Explanation of OpenShift Benefits:** Clearer explanations on how OpenShift enhances orchestration over Kubernetes are desired, especially for enterprise solutions. - **Completion of Course Series:** Learners hope that Red Hat will produce more courses on this topic in Udemy to complement this introduction. **Additional Feedback:** - **Course Value:** The overall sentiment is positive, with many learners finding the course valuable for understanding Docker, Kubernetes, and OpenShift. - **Learner Engagement:** Some users express a desire to learn more after completing the course, indicating that it successfully sparked their interest in the subject matter. - **Course Recommendation:** The consensus among reviewers is that this course is suitable for individuals who already have some basic knowledge of the technologies or are looking for an overview to decide if they want to delve deeper into these areas. **Final Thoughts:** This course is a valuable resource for those interested in understanding Docker, Kubernetes, and OpenShift. It provides a solid foundation but could benefit from additional content, including more advanced material, practical resources, and clearer explanations of the benefits of OpenShift. The course's engagement and clarity make it a recommended starting point for beginners.
