Q1. What is Docker primarily used for?
- Project management
- Version control
- Containerization of applications
- Network security
Q2. What is a Docker container?
- A virtual machine
- A physical server
- A lightweight, standalone, executable package that includes everything needed to run a piece of software, including the code, runtime, libraries, and dependencies
- A software development framework
Q3. How does Docker differ from virtual machines (VMs)?
- Docker containers are larger in size compared to VMs
- Docker containers require a hypervisor to run, while VMs do not
- Docker containers share the host operating system kernel, making them more lightweight and efficient compared to VMs, which each have their own operating system kernel
- Docker containers are more secure than VMs
Q4. What is the purpose of a Dockerfile?
- To store Docker container images
- To manage network configurations in Docker
- To define the steps needed to build a Docker image
- To automate software deployment processes
Q5. How do you build a Docker image from a Dockerfile?
- By manually typing commands into the Docker command-line interface (CLI)
- By exporting an existing Docker image to a text file
- By running the
docker buildcommand and specifying the directory containing the Dockerfile - By rearranging files and folders within the Dockerfile
Q6. What is Docker Hub?
- A physical location where Docker containers are stored
- A command-line interface (CLI) for managing Docker containers
- A cloud-based repository for Docker images, where users can store, share, and collaborate on container images
- A network protocol used by Docker for communication between containers
Q7. How do you start a Docker container?
- By exporting the container to an external file format
- By adjusting the container's color scheme and layout
- By running the
docker runcommand and specifying the Docker image to use - By rearranging files and folders within the container
Q8. What is Docker Compose used for?
- To manage Docker containers in production environments
- To automate software testing processes
- To define and run multi-container Docker applications, specifying the services, networks, and volumes required
- To monitor Docker container performance metrics
Q9. How do you stop a running Docker container?
- By deleting the container from the Docker Hub repository
- By adjusting the container's runtime configuration
- By running the
docker stopcommand and specifying the container ID or name - By rearranging files and folders within the container
Q10. What is a Docker volume?
- A type of Docker container
- A virtual machine disk image
- A persistent data storage mechanism used to share data between Docker containers and the host machine, ensuring data persistence even if the container is stopped or deleted
- A network interface used for communication between Docker containers
Q11. How do you remove a Docker container?
- By deleting the container from the Docker Hub repository
- By adjusting the container's runtime configuration
- By running the
docker rmcommand and specifying the container ID or name - By rearranging files and folders within the container
Q12. What is the purpose of Docker Swarm?
- To manage Docker container logs
- To automate software deployment processes
- To orchestrate and manage clusters of Docker containers, enabling high availability and scalability
- To monitor Docker container performance metrics
Q13. How do you inspect the configuration of a running Docker container?
- By exporting the container to a PDF file
- By adjusting the container's color scheme and layout
- By running the
docker inspectcommand and specifying the container ID or name - By rearranging files and folders within the container
Q14. What is the purpose of Docker networking?
- To manage Docker container logs
