- In which folder should the image downloaded by docker be placed?
- Docker images are stored in the /var/lib/docker/image folder by default. Docker stores images in a hierarchical manner: when a new image is downloaded, Docker checks whether it already exists in local storage. If it does not exist, Docker will download the image from the repository and store it in the image folder. You can change the storage location by setting the docker-root flag. Docker also provides other storage options such as distributed storage, remote storage, and custom storage drivers.

-
- Where is the file downloaded by docker?
- The downloaded files in the Docker container are stored in the container's independent file system by default. The specific location is /var/lib/docker/containers/[container_id]/[layer_id]/, where container_id is the container ID and layer_id is the ID of the source image layer. . The exact location of a specific file can be obtained through the docker inspect command.

- What are the advantages of docker compared to virtual machines?
- There are differences between Docker and virtual machines in isolating applications: Isolation level: Docker provides kernel-level isolation, while virtual machines provide hardware-level isolation. Performance: Docker containers start and run faster and have higher resource utilization. Resource utilization: Docker containers share the kernel and file system, saving disk space and memory. Portability: Docker containers are more portable across platforms than virtual machines. Management: Docker provides a lightweight command line-based management system, while virtual machine management tools are more complex.

- What is the difference between docker and virtual machine?
- The main difference between Docker and a virtual machine is: Docker virtualizes the operating system layer, while a virtual machine virtualizes the hardware layer. Docker containers share a kernel, while virtual machines have independent kernels. Docker containers are more lightweight and consume less resources; virtual machines require more resources. Docker container deployment is faster; virtual machine deployment takes longer. Docker containers can be easily moved between hosts; virtual machines are often tied to a specific host.

- How to find the cause and solve the problem of docker container startup failure
- Solution to Docker container startup failure: check whether the image exists and is not damaged (docker images, docker pull) resolve port conflicts (check port occupancy, modify container port mapping) increase resources (check resource usage, increase host resource allocation, reduce number of container processes) resolve permission issues (check user groups, use sudo) correct container configuration (check syntax, debug code)
