“docker cp” all files from a folder to existing co

Question

Am I missing something when I try to copy files from one folder to a existing container folder:

Doc

I want to copy files within the build(host) folder to html in my container:

docker cp ./src/build b081dbbb679b:/usr/share/nginx/html

To be clear; I need to copy from host to container.

But it copies the whole build folder and copies it to ..html/build

I just need the files(and sub folders) within the build folder to be copied into ..html.

Am I missing something or do I have to copy each file one by one?

Answer 1

Copy files/folders between a container and the local filesystem is like below formats:

• Copy file to folder inside container:

  docker cp ./src/build/index.html ContainerName:/app/
  

  above example shows index.html file is copying to app folder inside container

• Copy all files to folder inside container:

  docker cp ./src/build/. ContainerName:/app/
  

  above example shows all files inside build folder are copying to app folder inside container

Here is the explanation on how to use the CP command in docker, which will fix your issue with /. in end of SRC_PATH

SRC_PATH does not end with /.
the source directory is copied into this directory

SRC_PATH does end with /.
the content of the source directory is copied into this directory
