Hi all,

I want to ask about docker volumes, is it possible to mount multiple
directories in one volume?

Example:

\`\`\`docker run ..... -v nginx-data:/usr/share/nginx -v nginx-
data:/etc/nginx nginx\`\`\`

Yes. Buuut......

​

If the same files in said folder are being written to that might cause
issues..

I do have a few containers like that, but one folder is read-only...

What is your real problem that you want to do that?

It works, but all the files will be mixed together. This isn't really
a problem, since if the container wants to access `file_a` in volume1,
and `file_b` in volume2, then it will be able to do so no problem. The
problem is when you have two different files named `file_a` in the two
different mount points in the container. In that case, one file will
get overwritten by the other.

Just use separate volumes.
