Docker: Copy file from Server to Docker Container and vice versa

The docker cp utility copies the contents of SRC_PATH to the DEST_PATH. You can copy from the container’s file system to the local machine or the reverse, from the local filesystem to the container. 

The docker cp command assumes container paths are relative to the container’s / (root) directory. This means supplying the initial forward slash is optional;

Below mentioned commands are treated as identical:

• myContainer:/tmp/myFile.txt
• myContainer:tmp/myFile.txt

Local machine paths can be an absolute or relative value.

The command interprets a local machine’s relative paths as relative to the current working directory where docker cp is run.

 

Copying Remote Server File to Docker Container:

docker cp [source_pathOfFile_RemoteServer] [docker_containerName]:[destination_path_dockerContainer] 

docker cp /tmp/myFile.xls myContainer:/tmp/

 

Copying Docker Container File to Remote Server:

docker cp [docker_containerName]:[sourcepathOfFile_dockerContainer] [destination_pathOfFile_RemoteServer] 

docker cp myContainer:/tmp/myFile.xls  /tmp/myFile.xls 

 

Note: These commands need to be executed from Remote Server on which docker is installed and any docker container is up and running.
