Can not open /etc/nginx/conf.d directory

[shjanken]

first of all, sorry for my poor english

I use command

root > docker run -it --rm -v /root/dockers/openresty/conf.d/:/etc/nginx/conf.d/ openresty/openresty:stretch /bin/bash

to run a docker container.

Then I execute command in the docker

cd /etc/nginx/conf.d/
ls 

but get the permission problem.

ls: cannot open directory '.': Permission denied

Can you show the output of these commands:

# within container
ls -l /etc
ls -l /etc/nginx

# within host system
ls -l /root/dockers/openresty
ls -l /root/dockers/openresty/conf.d

I wonder if it is related to the issues like #24

[shjanken]

# within container
ls -l /etc
...

# within host system
ls -l /root/dockers/openresty

-rw-r--r--. 1 root root   90 6月  10 23:21 Dockerfile

ls -l /root/dockers/openresty/conf.d

-rw-r--r--. 1 root root 148 6月  10 22:44 hello.conf

Thank you very much.

I think this is a general Docker usage issue versus something with OpenResty. For example, can you access your mount on a generic stretch image?

docker run --rm -v /root/dockers/openresty/conf.d/:/conf debian:stretch-slim /bin/bash

Googling around shows that it might have to do with SELinux. Search for:
docker cannot open directory '.': Permission denied

I got it.
Thanks for help.

finally, I use the command to solved the problem.

root > docker run -it --rm -v /root/dockers/openresty/conf.d:/etc/nginx/conf.d:z openresty/openresty:stretch /bin/bash
