Dockr Desktop haunted binding mount

docker-desktop-haunted-binding-mount.md

Docker, run this container with my file mounted.

❯ docker run --rm -it -v /src/app/nginx/mime.types:/etc/nginx/mime.types nginx:latest ls /etc/nginx/
docker: Error response from daemon: not a directory.
See 'docker run --help'.

Eh, thanks I guess?

❯ ls -lha /src/app/nginx/mime.types
-rw-rw-r-- 1 nils nils 5.2K Feb 14 11:10 /src/app/nginx/mime.types

Well, you are not wrong...

Let's make a copy of the file with another name...

❯ cp /src/app/nginx/mime.types /src/app/nginx/mime.types2

Docker, run this container with the new copy of my file mounted.

❯ docker run --rm -it -v /src/app/nginx/mime.types2:/etc/nginx/mime.types nginx:latest ls /etc/nginx/
conf.d  fastcgi_params  mime.types  modules  nginx.conf  scgi_params  uwsgi_params
#

...right.
