How to import files from a Docker container to the host

Docker containers are created from a Docker image, while Docker images themselves can be generated using Docker command line tools or Dockerfiles. Copying data between containers is an important and basic feature of Docker, and copying data to other containers is a frequently used scenario. So how do you import the files from the Docker container into the host? The following small series will introduce you to the operation method of importing files in the Docker container to the host.

docker cp container ID: absolute path of the file container host path

docker cp use

docker cp 03091bf3d393: /root/Documents/combo.cpp . /

The above command copies the combo.cpp file in the /root/Documents/directory of the container with the ID 03091bf3d393 to the current directory of the host.

The above is the operation method of importing files in the Docker container to the host. Copying the files in the Docker container to other containers can play the role of backing up data. Users who want to import files to the host can refer to the method described above. .
