- What are the most common instructions in a dockerfile
- The most commonly used instructions in Dockerfile are: FROM: Create a new image or derive a new image RUN: Execute commands (install software, configure the system) COPY: Copy local files to the image ADD: Similar to COPY, it can automatically decompress tar archives or obtain URL files CMD: Specify the command when the container starts EXPOSE: Declare the container listening port (but not public) ENV: Set the environment variable VOLUME: Mount the host directory or anonymous volume WORKDIR: Set the working directory in the container ENTRYPOINT: Specify what to execute when the container starts Executable file (similar to CMD, but cannot be overwritten)

- What are the methods for docker to enter the container?
- Docker provides a variety of ways to enter a container, including: docker exec: execute a single command within the container docker attach: connect to the interactive shell of the container docker run --interactive --tty: run docker ps in interactive mode when starting a new container -a: List running containers, can be used with docker exec or docker attach docker-compose exec: If using Docker Compose, can enter the container in the Compose stack

- How docker enters the container
- Entering a Docker container requires the following steps: Open a terminal window. Use the docker ps command to view running containers. Use the docker exec -it <container name> /bin/bash command to enter the container. Execute commands within the container. Exit the container using the exit command.

- 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)
