Question 81119 in Docker Question posted in
The official documentation can be found here.

copy files from docker container to host, or mirror a folder

I have this docker-compose:

version: "3.9"

services:
  myserver:
    image: <some image>
    restart: always
    volumes:
      - ./res:/tmp/configs
      - ./myfolder:/tmp/logs

Should I expect to see the files that are in /tmp/logs inside the container, in the host folder ‘myfolder’?
‘myfolder’ is empty and I want it to be updated with the contents of the /tmp/logs folder in the container.

    What worked for me is using full path for the host path.

    C:myfolder for example.

    Can you put following in test.sh on the host?

    #!/usr/bin/env bash

testdir=/tmp/docker-compose

rm -rf "$testdir"; mkdir -p "$testdir"/{myfolder,res}
cd "$testdir"

cat << EOF > docker-compose.yml
version: "3.9"

services:
  myserver:
    image: debian
    restart: always
    volumes:
      - ./res:/tmp/configs
      - ./myfolder:/tmp/logs
    command: sleep inf
EOF

docker-compose up

    and run bash test.sh on the host and see if it works. host dir is /tmp/docker-compose/myfolder.
