This tutorial guides you on how to copy files from Docker container to local host. Let’s see how to use docker cp command to copy files from docker container to host with some examples.
Docker: Copy files from Docker container to local host
Before you begin make sure that you had installed Docker on your local machine. For example, I have installed docker and pulled mysql image from docker hub and running as a container as shown below.
C:\Users\temp> docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES cbc9f84f255c mysql:latest "docker-entrypoint.s…" 4 weeks ago Up 4 days 3306/tcp, 33060/tcp mysql
Let’s say you wanted to copy some specific file from root directory from your mysql docker container. For instance, lets try to copy the file initdb.sql. Note, you need to execute docker exec bash command to get to the file system of your docker container as shown below.
C:\Users\temp> docker exec -it mysql bash -l [email protected]:/# ls bin dev entrypoint.sh home lib media opt root sbin sys usr boot docker-entrypoint-initdb.d etc initdb.sql lib64 mnt proc run srv tmp var
Once you make sure that the file that you wanted to copy exists in the docker container, you can exit.
[email protected]:/# exit logout
Next step is important as you are going to copy the required file from docker container to your host using docker cp command.
> docker cp mysql:/initdb.sql C:\Users3248272\temp
Verify the file copied from docker container
Finally verify whether the file is copied to your local host temp directory.
C:\Users\temp> dir Volume in drive C is OS Volume Serial Number is C25A-D628 Directory of C:\Users3248272\temp 27-07-2021 19:42 <DIR> . 27-07-2021 19:42 <DIR> .. 29-06-2021 15:12 23,050 initdb.sql 1 File(s) 23,050 bytes 2 Dir(s) 57,866,977,280 bytes free
That’s it you could see that initdb.sql file is copied from docker container to your host. Make sure that you check the content of the files too.
Hope it is helpful 🙂
