Frequently Asked Questions

In this industry-designed Docker training, you will learn Docker and about its leading software containerization platform. You will learn how to deploy images on a cluster, install, maintain, run the Docker platform, and execute containerized apps from pre-existing images through practical projects. Additionally, you'll be able to pass Docker's certification exam for Docker Certified Associate.

The Docker Certification course cost depends upon the source you choose for completing your course. It is necessary to select a course from a reliable and renowned source like CloudThat. The Docker Certification course costs around 19900 +18% GST. You will get 50%- 60% hands-on lab sessions, industry-certified instructors, an interactive-rich classroom, integrated teaching assistance, and an authorized industry learning partner through this course.

Your software can be easily deployed using Docker, Microservices on Cloud, or Kubernetes, which will let you install it on hundreds of machines. Docker is a container, while Kubernetes is a container orchestration technology that can create, delete, and manage several containers. With the help of containers, you can create your application and deploy it with all its dependencies, such as an operating system like Linux or Windows, a runtime like Java,.NET, or Node.js, and any other third-party frameworks or libraries that your application uses.

Yes, the Docker course exam fee is included in the CloudThat Docker course fee. This two-day training offers a comprehensive understanding and practical expertise of Docker, the top trending subject on Google Trends. The fundamentals of containers, application containerization, practical experience with moving applications to Docker containers, and designing highly available and scalable applications deployed on Dockers are all covered in this course. Finally, we discuss setting up various user-facing applications hosted within containers. We also discuss networking in Docker.

You're required to know the answers to the questions in this category of Docker interview questions. These are the most fundamental inquiries. Starting with these, an interviewer will gradually raise the level of difficulty. Various questions are asked in an interview, from basic to advanced levels. Basic questions like 'What is Docker?' 'What is containerization?' and advanced questions like 'What is the lifecycle of a Docker Container?' Or 'How do you get the number of containers running, paused, and stopped?'.

Docker solves the problem of application portability. With Docker, you can package an application with all of its dependencies into a single image that can be run on any machine that has Docker installed. This makes it much easier to deploy applications to production and to move applications between different environments.

There are a few security considerations to keep in mind when using Docker. First, containers share the host operating system kernel, which means that a security vulnerability in one container could potentially affect all of the containers on the host machine. Second, containers are often run with root privileges, which can also increase the risk of security breaches. To mitigate these risks, it is important to use a secure Dockerfile when building images and to configure Docker security settings correctly. It is also important to monitor Docker containers for signs of malicious activity.

A Docker image is a blueprint for a Docker container. It contains the application code, the operating system, and all of the dependencies that the application needs to run. A Docker container is a running instance of an image. When you run a Docker image, Docker creates a container from the image and starts the application inside the container.
