How can change Nginx default log file location in docker setting - php

Question

I'm very new to docker and trying build docker compose with multiple service/app, also set the log file place separately.
If I run docker compose up will cause the open() file error like
FPM-nginx | 2022/10/06 01:40:54 [emerg] 1#1: open() "/var/www/FPM/log/nginx/error.log" failed (2: No such file or directory)
FPM-nginx | nginx: [emerg] open() "/var/www/FPM/log/nginx/error.log" failed (2: No such file or directory)
According relative answer, I've try adding the new command in Dockerfile but still causing the error.
The answers tried
Nginx access log file path
The answers tried 2
Nginx log location
Currently Dockerfile docker-compose.yml nginx.conf like below
Dockerfile
FROM php:8.0.2-fpm
RUN mkdir -p /var/www/FPM/log/nginx/ \ <<<<<<<<< This is new add
touch /var/www/FPM/log/nginx/error.log \ <<<<<<<<< This is new add
touch /var/www/FPM/log/nginx/access.log \ <<<<<<<<< This is new add
apt-get update && apt-get install -y \
git \
curl \
zip \
unzip
WORKDIR /var/www/FPM
nginx.conf
server {
listen 80;
index index.php;
root /var/www/FPM/public;
error_log /var/www/FPM/log/nginx/error.log;
access_log /var/www/FPM/log/nginx/access.log;
error_page 404 /index.php;
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass app:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
location / {
try_files $uri $uri/ /index.php?$query_string;
gzip_static on;
}
}
docker-compose.yml
version: "3.8"
services:
app:
build:
context: ./
dockerfile: Dockerfile
container_name: FPM-app
restart: always
working_dir: /var/www/FPM
volumes:
- ../src:/var/www/FPM
nginx:
image: nginx:1.23.1-alpine
container_name: FPM-nginx
restart: always
ports:
- 8000:80
volumes:
- ../src:/var/www/FPM
- ./nginx:/etc/nginx/conf.d
I've also tried place
error_log /var/www/FPM/log/nginx/error.log;
access_log /var/www/FPM/log/nginx/access.log;
under location / but still cause the error
location / {
error_log /var/www/FPM/log/nginx/error.log;
access_log /var/www/FPM/log/nginx/access.log;
}

You've multiple issues with you docker and docker-compose files.
According to your docker-compose.yml, when you would be doing docker-compose up you'll have two containers running one brought up from the docker image built at the time and the other brought up from public nginx:1.23.1-alpine image. The first image built will have the /var/www/FPM/log/nginx/ folder along with the error.log and access.log files but docker-compose up will overwrite the content because of this line:
volumes:
- ../src:/var/www/FPM
That being said, you don't even need that folder and those files in the first (app) container in the first place. You need them in the nginx container. So you can remove these lines from the Dockerfile:
mkdir -p /var/www/FPM/log/nginx/ \
touch /var/www/FPM/log/nginx/error.log \
touch /var/www/FPM/log/nginx/access.log \
Instead, create error.log and access.log inside your src directory or if you would choose at src/log/nginx/ location for brevity. And mount these files in your docker compose file.
