Copy File From Container To Host

The short answer

The docker cp command allows you to copy files and directories from a container's file system to your local machine, whether the container is running or stopped.

 $ docker cp container:src_path dest_path 

Run in Warp

Where:

• src_path is the path on the container of the file you want to copy.
• container is the name or the ID of the container you want to copy files from.
• dest_path is the path on your local machine of the directory you want to copy files to.

To get the name or ID of the container you want to copy files from, you can use the docker ps -a command, which will output the list of all the running and stopped containers.

Use Warp's Workflows feature to easily recall the syntax

If you’re using Warp as your terminal and you need to quickly retrieve this command, you can use Warp's Workflows feature by pressing CTRL-SHIFT-R and typing copy from container:

Then pressing ENTER to use the suggested command:

Using docker cp to copy files to the local host

Copying individual files

To copy a file from a container to your local host, you can specify the destination directory using either its relative or absolute path:

 $ docker cp container:/app/file.txt .

Run in Warp

Alternatively, you can copy and rename at the same time, by providing the full destination path:

 $ docker cp container:/app/script.js ./index.js

Run in Warp

Note that it is not possible to copy multiple files at once using the docker cp command, unless you copy the entire directory that contains them (if located in the same directory).

Copying entire directories recursively

When copying a directory, the docker cp command will behave like the Unix cp -a command, which means that the directory will be copied recursively with permission preserved if possible.

 $ docker cp container:/app/server/ ./server

Run in Warp

Copying absolute and relative paths, such as a parent directory

The docker cp assumes container paths are relative to the container's root directory (i.e. /). A source path can therefore be written with or without the initial forward slash, as docker cp will see these two commands as identical:

 $ docker cp container:tmp .
 $ docker cp container:/tmp .

Run in Warp

Destination paths on the other hand, can be written either in their relative form:

 $ docker cp container:/tmp/file.txt ./file.txt

Run in Warp

Or in their absolute form:

 $ docker cp container:/tmp/file.txt /home/johndoe/Documents/file.txt

Run in Warp

You can learn more about the docker cp command in the official Docker documentation and in our article on how to copy files and directories to a running Docker container.
