Docker - Interview Question Set-2
Question-6: How does Docker handle resource management, such as CPU and memory allocation?
Answer: Docker provides resource management capabilities, allowing administrators to specify resource constraints, such as CPU and memory limits, for containers.
This helps ensure that containers do not consume excessive resources and negatively impact the host system or other containers.
Question-7: How can you implement a continuous integration and deployment pipeline using Docker?
Answer: A continuous integration and deployment pipeline using Docker can be implemented by automating the build, test, and deployment of Docker images. This can be done using a variety of tools, such as Jenkins, TravisCI, and GitLab CI/CD.
The pipeline can be configured to automatically build and test the image when changes are pushed to the source code repository, and then deploy the image to production when tests pass.
Question-8: What is the difference between a Docker image and a Docker container?
Answer: A Docker image is a static, immutable, file that contains the definition of a Docker container, including the application code, dependencies, libraries, and runtime environment.
A Docker container is a running instance of a Docker image. In other words, a Docker image is a blueprint, while a Docker container is a running instance of that blueprint.
Question-9: How can you optimize the size and performance of Docker images?
Answer: Docker images can be optimized for size and performance by using multi-stage builds, using smaller base images, reducing the number of unnecessary files and dependencies, and using compressed file formats.
Additionally, it is recommended to regularly clean up and prune old images and containers that are no longer needed.
Question-10: How can you troubleshoot issues with running containers, such as debugging and logs analysis?
Answer: Troubleshooting issues with running containers can be done using several tools, such as Docker logs, Docker inspect, and Docker events.
Additionally, it is recommended to regularly monitor and analyze the logs generated by containers and the host system to identify and diagnose issues.
