"docker cp" all files from a folder to existing container folder
DockerDocker Problem Overview
Am I missing something when I try to copy files from one folder to a existing container folder:
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?

Here is the explanation from the doc on how to use the cp command in docker, which will fix your issue with /. at the end of SRC_PATH:
> * SRC_PATH does not end with /. (that is: slash followed by dot)
> * the source directory is copied into this directory

Solution 2 - Docker
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
Solution 3 - Docker
Just use "." (Dot - instead of "*" in Linux) after your file path, it will copy entire files from the folder
docker cp /file/path/* containerId:/filepath/nginx/html/
docker cp /file/path/. containerId:/filepath/nginx/html/
Solution 4 - Docker
In Windows, you can iterate through all txt files in a folder and copy them into the container with this command:
for /r %i in (*.txt) do docker cp %i containerId:/blabla/bla/
