I've explained how to get in and out of Docker's container. Today, in Docker, the host and container (container) Copy the method of transferring files to each other. 1 copy files from container to host

Copy mode is:

Docker CP container name: The file name and its path to be copied in the container should be copied to the corresponding path in the host.

For example, the container:

MyContainer

Path in:

/opt/testnew/

Files under:

File.txt

Copy to host:

/opt/test/

Path, the following commands are executed in the hosting host:

Docker CP mycontainer:/opt/testnew/file.txt/opt/test/

2 Copy files from host to container

Copy mode is:

Docker the file name to be copied in the CP host and its path container name: the corresponding path to be copied to the container

For example, the path to the host hosts:

/opt/test/

Files under:

File.txt

Copy to Container:

MyContainer

Of

/opt/testnew/

Path, the same commands are executed in the host computer as follows:

Docker Cp/opt/test/file.txt mycontainer:/opt/testnew/

3 The Copy command will take effect regardless of whether the container is activated.

Note that the copy command takes effect regardless of whether the container is started or not.
