alpine-nginx | nginx built from source on Alpine Linux | Continuous Deployment library

I am looking for a Dockerfile which has Nginx, Php7, MongoDB & Redis enabled on Alpine. Managed to get below but while executing it I see below errors. Please suggest.

Dockerfile:-

Using the following dockerfile, I'm trying to create a folder which is writable for PHP.

I have built a docker image over nginx-alpine one. I know that, at the start, the nginx image reads some configuration file and starts the server.

The configuration file (I can see that from github) reads the configuration stored inside /etc/nginx.

I'd like to perform some runtime operation on that configuration before actually starting the script. This configuration is based on an environment variable that I would set inside of my deployment descriptor.

I know that I could simply overwrite the script, but what if in further versions they change it? I would have to keep updating it too.

So, would it to be possible to:

1. execute some custom shell instructions
2. give the command to the default image entrypoint?

I have a Dockerfile for my Symfony application but the container doesn't have write permissions into the cache and logs directories.

I tried with the Symfony docs for permissions, but it is not working. I already set the container user to root, but the problem is the same.

Here is my Dockerfile:

I've searched and searched, and read the documentation at http://docs.guzzlephp.org/en/stable/request-options.html and confirmed the error at https://curl.haxx.se/libcurl/c/libcurl-errors.html and for the life of me, I cannot figure out what's going on. I have the URLs for both app-one and app-two in my /etc/hosts file, and I know they're correct as I can access them in my browser and with cURL via terminal just fine.

My setup:

Docker containers configured as:

I'm using rancher with this docker-compose:

I've taken on a project built on Docker containers and I'm having it to run smoothly.

My containers build successfully, but when I try getting to the website, nginx gives me a 502 with this error in the logs:

How can I run a Docker image with NGINX, phpBB (and all required stuff like php installed) with persistence (Changes on the board shouldn't be lost) and with the database on another host (which already exists). So, let's assume I have the following: MySQL on 192.168.2.233 (local address) on port 3307 running. Now I want to create a Docker image with Alpine Linux (The smallest propably), NGINX and phpBB where the board runs on the NGINX webserver and connects to the database. Changes on the board (E.g. changing the webserver settings or so) should be persisted within the container. How can I do that?

EDIT:

The database on server 192.168.2.233 is already existing! So no, I don't need two or more Docker containers. I need one Docker container with phpBB running on the NGINX webserver and connecting to the database on another host in the same network. The container should use persistence (volumes) to save the settings made in phpBB.

I tried to use the following Dockerfile and modified it: https://gitlab.com/boxedcode/alpine-nginx-php-fpm/blob/master/Dockerfile --> https://drive.google.com/open?id=1CW68OFCJE9RjIe8_RBC8q5Fa6juRtxmR

I'm using the following script to deploy new image to a kubernetes cluster:
