How to fix Quay nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (2: No such file or directory)
Problem
In your quay log, you see the following error message:
nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (2: No such file or directory)
nginx stderr | 2024/07/13 01:04:58 [emerg] 175#0: open() "/var/log/nginx/error.log" failed (2: No such file or directory)
Solution:
Note: This error typically isn’t critical, you can just ignore it.
You have likely mounted a docker volume as /var/log
in your quay setup, e.g. in docker-compose.yml
:
services:
quay:
image: quay.io/projectquay/quay:latest
# [...]
volumes:
- ./quay_log:/var/log
# [...]
In this directory, create the nginx
directory and make it writeable using
mkdir -p quay_log/nginx
chmod a+x quay_log/nginx
After that, restart quay and the error should disappear.
