Why take this course?

If you're a Java developer, Docker is a true game changer for you!

Developing Java applications in large enterprises is no easy task. Every day you are asked to work with many different technologies. In the morning, you might need to save data to a MySQL database. In the afternoon, you might be working with RabbitMQ. Tomorrow you might be asked to work with Mongo or Redis.

Think about what you need to do when working with all these different technologies.

If you install all these on your laptop, it becomes cluttered and slow. Sure, you could use VMs to run these - if you really want to slow down your laptop. Virtual Machines are awesome, but VMs can also be huge resource hogs.

If you're on a dev team, you can set up dedicated development servers. But then you don't have a clean development environment. And your development work becomes dependent on access to the development servers.

Docker is an exciting technology you can leverage for enterprise development.

The popularity of Docker has been explosive. Much of the industry focus has been on DevOps. But more so on the Operations part.

Did you know Google creates roughly 285 MILLION Docker containers per day?

Docker is clearly a popular technology for running cloud scale applications like GMail.

But as a Java developer, what does Docker mean to you?

Are you working with MySQL? There's a ready made Docker image for you.

Postgres? Mongo DB? Redis? Cassandra? RabbitMQ? ActiveMQ? Kafka?

Yep, there's Docker images you can download and use today.

You can use Docker for a lot more than just your local development.

Are you developing microservices? If you are not already deploying your microservices in Docker containers, chances are you soon will be.

Introduction to Docker

This course starts off assuming you have no knowledge about Docker.

You will learn why Docker is not like a Virtual Machine.

Right away, you will learn how to run a Docker container with a Docker Image pulled down from Docker hub.

As the course progresses, you will learn how to create your own Docker images and publish those images to Docker hub.

Java DevOps with Docker

Through the use of the Fabric8 Maven plugin, you will learn how to automate many Docker tasks, such as creating images for microservices.

Docker Compose is a powerful tool to run multiple Docker containers. You will learn how to run how to run an application consisting of a Spring Boot web application, RabbitMQ, a page view microservice, and a MySQL database. Through Docker Compose, with a single command, you will be able to start or stop this application on any Docker machine!

Using Docker Swarm Mode

You'll learn how Docker Swarm Mode does container orchestration. In this course, you will provision your own Docker Swarm Cluster in the cloud. You will deploy a containerized Java application into a Docker Swarm Cluster. You'll see what a powerful feature Docker Swarm's routing mesh is, and how you can dynamically scale your application.

Our review

📝 **Overall Course Rating**: 4.15 The course has received a wide range of reviews from users with varying levels of expertise. Below, we'll break down the pros and cons based on these reviews to give a balanced view of the course. ### Pros: - **Comprehensive Explanation**: The instructor's explanation of Docker concepts is clear and thorough, with many reviewers highlighting the detailed nature of the instruction (🌟). - **Real-world Application**: The course focuses on applying Docker in the context of Spring microservices, which is practical and beneficial for professionals using Docker in their day-to-day work (🌟). - **Useful Resources**: The course provides a comprehensive list of resources and references, which is highly appreciated by learners who are looking to further their understanding after completing the course (📚). - **Engaging Teaching Style**: The instructor's teaching style is considered very effective, making complex topics more accessible and engaging for learners (🎓). - **Visual Cues**: Although some reviewers requested more visual cues for global concepts, others found the existing visual aids to be helpful in understanding the material (🖼️). - **Practical Tasks**: The tasks given throughout the course are designed to encourage active learning and consolidation of knowledge, which is an excellent teaching approach (🛠️). ### Cons: - **Outdated Content**: Several reviewers noted that some sections of the course, particularly those involving Maven and specific Docker images like MySQL, are outdated and may not work with current Docker versions or practices (⏳). - **Technical Issues**: Learners have reported issues with following along due to outdated commands and tools not functioning as described in the course (🛠️❌). - **Lack of Updates**: The absence of updates to the course content has led to a disconnect between what is taught and what is current in Docker technology (🚀). - **Audio Quality**: Some users have pointed out poor audio quality, which can affect the learning experience (🔊🚫). - **Unnecessary Introductory Content**: At least one reviewer found parts of the introduction to be unnecessary and time-consuming, though this seems to be a minority view (⌛️). - **Email Privacy Concerns**: There have been concerns regarding the collection of student emails for promotional purposes, with some learners experiencing unwanted communications beyond what was agreed upon during the course (📧⚠️). ### General Observations: - The course is considered a good starting point for those new to Docker, particularly those with a background in Java development. - Despite its strengths, the course has significant limitations due to its outdated content, which may require learners to seek additional resources or tutorials to stay current. - Learners who have completed the course and found it lacking may consider requesting a refund, depending on the policies of the platform they purchased the course from (💸). In conclusion, while the course offers valuable insights into Docker and its application with Java, it is essential to approach it with the understanding that some content will require verification against current resources due to its outdated nature. Learners should be prepared to complement this course with additional learning materials to ensure they gain a complete understanding of Docker technologies.
