I'm fiddling with Docker, trying to setup a Docker composition with Nginx and PHP-FPM running on separate Alpine containers. My setup is available on GitHub at https://github.com/sparkbuzz/lemp_docker, my docker-compose.yml looks as follows:
version: '3'
services:
alpine_nginx:
build: ./nginx
container_name: alpine_nginx
links:
- alpine_php
ports:
- "80:80"
alpine_php:
build: ./php
container_name: alpine_php
ports:
- "9000:9000"
I am able to build the images successfully, and when I visit localhost in my browser, I can see the index.html served by Nginx. However, when trying to access phpinfo.php, I get a 502 - Bad Gateway error
I can docker exec -it ... /bin/ash into both the running instances, and it seems the services are running happily, however, it's clear PHP-FPM on port 9000 is never even hit.
Here's some feedback from my console:
Recreating alpine_php ...
Recreating alpine_php ... done

Recreating alpine_nginx ... done

I'm so close, but not sure why Nginx isn't happy with the PHP upstream. Nginx config is as follows:
server {
listen 80;
server_name localhost;
location / {
root /var/www/localhost/htdocs/;
index index.html;
}
location ~* \.php$ {
fastcgi_index index.php;
fastcgi_pass alpine_php:9000;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /var/www/$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
}
}
How do I get Nginx talking to PHP FPM?
You are listen 127.0.0.1 in your php-fpm config.
Add this to php/Dockerfile
RUN sed -i 's/127.0.0.1:9000/0.0.0.0:9000/g' /etc/php7/php-fpm.d/www.conf

I'm trying to configure nginx config in Docker but when I start "sudo docker-compose up -d" and try to connect to "http://localhost:8098/" I see: File not found. and logs like:

I'm completely sure that I have correct paths to my (local) project and to my index.php file
Please help me. There was an error, a minor error. Maybe I just do not see it, but I had no idea. The essence of the problem: I am setting up a docker environment. Brought nginx, fpm. When url get a php file, nginx return 502.

I'm sorry for wasting time. Please help me. Thank!
I have dealt with the problem. I do not want to write in stages, but I will say it in a nutshell. The problem is caused by the fact that my OS build is centos 8. First of all, the incorrect behavior of containers will show the use of Dockerfile, problems with the repo will be identified. It is possible to solve these problems, but for me it became a trigger, which shows that my environment is not correct. Then I went and installed all the packages for docker as directed for installation under Centos 8.

I run a NGINX-PHP7-COMPOSER image that works well but when using Slim Framework I had to change Nginx's default config to make the URL rewrites work.
And now it show this error in the logs:

Do you have any idea of what is going wrong?
I'd like to setup an completely LNMP environment with docker on a machine. But there is something wrong with separated php-fpm & nginx container.
What I'v done is :
pull images from docker.io :
docker pull php:7.1-fpm
docker pull nginx
run with image :
docker run -d --name php-fpm -v /data/Docker/php-fpm/configs/:/usr/local/etc/php-fpm.d -v /data/Docker/nginx/html:/var/www/html php:7.1-fpm
docker run -d --name nginx -v /data/Docker/nginx/configs/:/etc/nginx -v /data/Docker/nginx/html:/var/www/html -p 80:80 --link php-fpm nginx
All directories & files are 755 privileges.
Config files r below :
nginx.conf
server {
listen 80 default_server;
server_name SkyEyeLab;
root /var/www/html;
fastcgi_read_timeout 90;
location ~ \.php {
fastcgi_pass php-fpm:9000;
}
}
And php-fpm.conf(some of important config sections):
listen 0.0.0.0:9000
listen.allowed_clients = any
Then I checked the environment of nginx & php-fpm :
[root#w-Lab01 ~]# docker ps

Everything seems fine. Then I create a.php under /data/Docker/nginx/html(which is mouted to nginx's /var/www/html directory) with following content :
<?php
phpinfo();
?>
Then access http://localhost:80/a.php in web browser.
But I only got an empty page, I checked the access.log of nginx :
[root#w-Lab01 ~]# docker logs 6faf4a4b4f7e

It seems a.php is correctly parsed & executed. But why I can not see phpinfo() result in web browser ?
well, after I changed nginx's config file :
server {
listen 80 default_server;
server_name SkyEyeLab;
root /var/www/html;
fastcgi_read_timeout 90;
location ~ \.php {
fastcgi_pass php-fpm:9000;
}
}
to
server {
listen 80 default_server;
server_name SkyEyeLab;
root /var/www/html;
fastcgi_read_timeout 90;
location ~ \.php {
fastcgi_pass php-fpm:9000;
include fastcgi.conf;
}
}
erverything goes fine.
fastcgi.conf is environment config file. you can check under your nginx's config directory(usually /etc/nginx), and see if there is fastcgi.conf or fastcgi_param in it.
maybe, if you want to use the name "php-fpm" in the nginx conf, you need to link the container like this:
docker run -d --name php-fpm -v /data/Docker/php-fpm/configs/:/usr/local/etc/php-fpm.d -v /data/Docker/nginx/html:/var/www/html php:7.1-fpm
and after:
docker run -d --name nginx --link php-fpm:php-fpm -v /data/Docker/nginx/configs/:/etc/nginx -v /data/Docker/nginx/html:/var/www/html -p 80:80 --link php-fpm nginx
I have a simple docker-compose config with php-fpm and nginx, and I can't see any php file. When I go to localhost, it shows File Not Found.
I tried everything I could find on the net, but everything I have tried has failed.
It works fine for html, but not for php files. Seems to be a path issue, or something like that.
I come across this error when I docker-compose logs:

Any idea would be greatly appreciated. I'm sure there is something I didn't get. Thanks in advance.
Here is how you can find the problem
Switch on the nginx debug mode with custom command, eg:
docker-compose.yml
web:
image: nginx
volumes:
- "~/www/project:/var/www"
- "~/www/project/vhost.conf:/etc/nginx/conf.d/site.conf"
# Add this row:
command: [nginx-debug, '-g', 'daemon off;']
Edit your "site.conf" file (in this example it is the ~/www/project/vhost.conf file) Switch on the debug mode by the error_log (add "debug" word at the end):
error_log "/var/log/nginx/error.log" debug;
(Re)start the "web" container:
docker-compose stop web
docker-compose up -d web
Test the containers, are all containers running?
docker-compose ps
Test in browser
"Connect" and view or download ( http://blog.dcycle.com/blog/ae67284c/docker-compose-cp ) and view the /var/log/nginx/error.log file.
The problem in the most of case
You haven't set yet or you are using different directory structure in web and php-fpm. If you want to use different structure than you have to set the "fpm structure" at the fastcgi_param SCRIPT_FILENAME place, like this:
If your docker-compose.yml contains like this:
phpfpm:
image: php:fpm
volumes:
- "~/www/project:/var/www/html/user/project"
# ^^^^^^^^^^^^^^^^^^^^^^^^^^ the path in the php-fpm container
You have to set this in "site.conf" in nginx container:
fastcgi_param SCRIPT_FILENAME /var/www/html/user/project$fastcgi_script_name;
# ^^^^^^^^^^^^^^^^^^^^^^^^^^
Finally found it:
I was missing this line in the volume of PHP section of docker-compose:
"./html:/usr/share/nginx/html"
here's what the docker-compose should look like:
project3-front:
image: nginx
ports:
- "80:80"
links:
- "project3-php:project3-php"
volumes:
- ".:/home/docker"
- "./nginxdir/default.conf:/etc/nginx/conf.d/default.conf"
- "./html:/usr/share/nginx/html"
project3-php:
build: phpdir
volumes:
- ".:/home/docker:rw"
- "./html:/var/www/html"
ports:
- "9000:9000"
working_dir: "/home/docker"
The absolute root (here "/usr/share/nginx/html") in the nginx default.conf file had to be set as well in the php part of docker-compose (was only under nginx before)
That's a relief ;)
In my case the volumes: of php and nginx were pointing a the correct (and hence the same) directory. But in my nginx config there was a NGINX_SERVER_ROOT: pointing the wrong way.
So make sure you double check all volumes and root directory settings. Some are easy to overlook.
While replacing $document_root$fastcgi_script_name; by /var/www/html/user/project$fastcgi_script_name; might fix the issue, the more elegant approach in my opinion would be just changing the nginx root directory in the default.conf:
server {
listen 80;
server_name localhost;
index index.php index.html;
error_log /var/log/nginx/error.log warn;
access_log /var/log/nginx/access.log;
root /var/www/html;
location ~ \.php$ {
fastcgi_pass project3-php:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
And in docker-compose.yml:
project3-front:
image: nginx
ports:
- "80:80"
links:
- "project3-php:project3-php"

I had the same problem but this wasn't solved by any of this answer here:
Yesterday a Docker Update hits in - which has been installed. The problem depending on this update is, that the (vEthernet (DockerNAT)) Network has been changed. In that way my firewall (in my case Kaspersky) reset my network firewall to "public" instead of "trustable".
I figured this out by open "Docker -> Settings -> Shared Devices". On the first look, everthing seems fine. There was a "tick" on each device I need to be shared. Next I tried to disable and enable my shared devices again. By enable my shared device again the default error "A firewall is blocking file Sharing between Windows and the containers. See documetation for more info." came up. -> PERFECT!!. The shared device is not able to access the files anymore but Docker persists in the state that its all fine.
So I could fix it by:
Set (vEthernet (DockerNAT)) Network as trusted again in my Kaspersky "Firewall - Network" settings.
Restarted my docker container by using docker-compose up and everthing runs like a charm. My files could be accessed again.
One of the case might be, Your running the docker container and did composer install/update
then run following to restart container
`docker-compose down` `docker-compose up -d`
