Steps to Copy file from docker to local host
There are two steps to copy a file from a Docker container to the local host or system so that you can use the file outside of Docker:
- Get the container ID of Docker
To get the list of ID of all Docker container in your system, use this command:
sudo docker container ls
The output will be like:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
055baag9e572 quay.io/pypa/opengenus "opengenus" 12 minutes ago Up 12 minutes opengenus_env
Identify the ID of your container. In our case, it is 055baag9e572.
If you are within the concerned docker container, the ID is mentioned in the terminal as well:
[root@<container-id> DIRECTORY]#
Like:
[root@055baag9e572 DIRECTORY]#
- Copy file from docker
The command to copy a file from Docker to local host is:
sudo docker cp <container_id>:/path/to/file .
In our case, the command will be:
sudo docker cp 055baag9e572:/home/opengenus.txt .
With this article at OpenGenus, you must have the complete idea of how to copy a file from a docker container to local host.
