Preface
Main idea: Command to copy file to container
I’m use command
docker run -t -i -v <host_directory>:<container_directory> mysql /bin/bash
Docker cp command
The cp command can be used to copy files.
One specific file can be copied TO the container like:
docker cp foo.txt mycontainer:/foo.txt
One specific file can be copied FROM the container like:
docker cp mycontainer:/foo.txt foo.txt
For emphasis, mycontainer is a container ID, not an image ID.
Multiple files contained by the folder src can be copied into the target folder using:
docker cp src/. mycontainer:/target
docker cp mycontainer:/src/. target
Note: In Docker versions prior to 1.8 it was only possible to copy files from a container to the host. Not from the host to a container.
