I am trying to build a backup and restore solution for the Docker containers that we work with.
I have Docker base image that I have created,
ubuntu:base, and do not want have to rebuild it each time with a Docker file to add files to it.
I want to create a script that runs from the host machine and creates a new container using the
ubuntu:base Docker image and then copies files into that container.
How can I copy files from the host to the container?
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
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
Reference: Docker CLI docs for
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.
