Nginx in Docker cannot find the file

Question

I'm running Nginx inside Docker and from logs, I can see that Nginx cannot find mime.types file. The line from Nginx.conf:

include      mime.types;

Here is the Dockerfile.

FROM nginx:alpine
COPY . ./etc/nginx
RUN ls -la /etc/nginx

Here is the list of files in the working directory:

drwxr-xr-x    1 root     root          4096 Jul 30 07:35 .
drwxr-xr-x    1 root     root          4096 Jul 30 07:35 ..
-rw-r--r--    1 root     root            58 Jul 29 21:48 Dockerfile
drwxr-xr-x    2 root     root          4096 Jul 29 21:36 certs
drwxr-xr-x    2 root     root          4096 Jul  6 19:40 conf.d
-rw-r--r--    1 root     root          1077 Jul  6 15:21 fastcgi.conf
-rw-r--r--    1 root     root          1007 Jul  6 15:21 fastcgi_params
-rw-r--r--    1 root     root          5290 Jul  6 15:21 mime.types
lrwxrwxrwx    1 root     root            22 Jul  6 19:40 modules -> /usr/lib/nginx/modules
-rw-r--r--    1 root     root         10729 Jul 30 07:35 nginx.conf
-rw-r--r--    1 root     root           636 Jul  6 15:21 scgi_params
-rw-r--r--    1 root     root           664 Jul  6 15:21 uwsgi_params

And this is the error log:

2021/07/30 07:35:34 [emerg] 1#1: open() "/etc/nginx/mime.types" failed (2: No such file or directory) in /etc/nginx/nginx.conf:52

I can clearly see that nginx.conf is in the same directory but couldn't be found.

Try removing the leading dot in COPY . ./etc/nginx, i.e. try with COPY . /etc/nginx. — Marko E

How about adding this to nginx.conf: include /etc/nginx/mime.types; instead of only mime.types? — Marko E

@MarkoE, nope, still the same error, that is very weird actually. — andrey.shedko

@andrey.shedko When you map ./nginx:/etc/nginx, the volume mapping wins and 'hides' the files in the image. — Hans Kilian

As you say in the comment, you map a directory to /etc/nginx when you run the container.

When you map ./nginx:/etc/nginx, the volume mapping wins and 'hides' the files in the image.

Thank you, but what is the proper way to fix this issue?

Hans Kilian Over a year ago

There are probably a number of ways to fix it. Can you include all the files in the image, so you don't need to map a volume? Can you instead have all the files in your host directory, so there are no files in the image to hide? Maybe you place mime.types outside the /etc/nginx path and change nginx.conf to point at it. I don't know what would work best in your case.

Hans Kilian Over a year ago

If you only map a few files, you could create volume mappings for each of them. Or you could create symlinks for the files you want to map in /etc/nginx/ in the image to a different directory, and then create a mapping for that directory.
