How to copy files from host to Docker container?

0 votes

I have Docker base image that I have created, ubuntu:base, and do not want 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?

Can anyone help me with this query?

Thanks

Here is what you can do. The cp command can be used to copy files. One specific file can be copied like:

docker cp foo.txt mycontainer:/foo.txt
docker cp mycontainer:/foo.txt foo.txt

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 cp

I hope it would help you resolve your query.
