kandi X-RAY | fpm Summary

fpm is a C++ library typically used in Utilities, Math applications. fpm has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A C++ header-only fixed-point math library. "fpm" stands for "fixed-point math". It is designed to serve as a drop-in replacement for floating-point types and aims to provide as much of the standard library's functionality as possible with exclusively integers. fpm requires C++11 or higher. fpm is designed to guard against accidental conversion to and from floats and supports many of the standard C++ maths functions, including trigonometry, power and logarithmic functions, with performance and accuracy generally comparable to alternative libraries.

QUESTION

When running Nginx + PHP-FPM in two different containers, can that configuration ever work without sharing a code volume?

Asked 2022-Apr-04 at 12:51

I have the following docker-compose.yaml file for local development that works without issue:

Nginx container just runs the webserver with an upstream pointing to php
Php runs just php-fpm + my extensions
I have an external docker-sync volume which contains my code base which is shared with both nginx + php.
The entire contents of my application is purely PHP returning a bunch of json api data. No static assets get served up.

It's not required to share the volume between those two containers, the PHP scripts are required only by the PHP container, for Nginx it's only required to have network access to the PHP container, so it can proxy the requests.

To run your application on AWS ECS, you need to pack Nginx + PHP in the same container, so the load balancer proxy the request to the container, Nginx accepts the connection and proxy it to PHP, and then return the response.

Using one container for Nginx to act as a proxy to multiple PHP containers it's not possible using Fargate, it would require running the containers on the same network and somehow making the Nginx container proxy and balancing the incoming connections. Besides that, when a new PHP container were deployed, it should be registered on Nginx to start receiving connections.

Can't connect to local MariaDB running with Docker with PHP PDO

Asked 2022-Feb-23 at 07:34

I have a local Docker compose stack with MariaDB, PHP-FPM and Nginx running on my machine for local development. I can successfully access the webpages served by Nginx on http://localhost:8080/ on my browser. I can also successfully connect to the database using TablePlus, a local GUI DB browser, on host 127.0.0.1, port 8889. It works with user root and password root (but weirdly enough not with any other user set as the MYSQL_USER, MYSQL_PASSWORD env variables I catch in the Docker compose).

Anyway, when I try to connect with PHP/PDO using the following PHP code, same credentials:

As answered by @danblack, since the connection to the DB is done from inside a Docker container to another container:

Connections between containers always use not remapped ports. So the connection to the DB container needs to use internal, MariaDB standard port 3306 - not the remapped, exposed 8889 port.
The host name of the DB must be the DB container name (in this case, the MariaDB container name mariadb-10.5), not 127.0.0.1 or localhost.

So all in all the PHP/PDO connection object becomes:

I'm using ECS with Fargate and trying to create a bind mount on ephemeral storage but my user (id 1000) is unable to write to the volume.

According to the documentation, it should be possible.

However the documentation mentions:

Try to run command netstat -nltp. It shows active addresses and ports. Your nginx process should be run at 0.0.0.0:8000. 0.0.0.0 means the nginx process is available from anywhere.

If your nginx process is ran by any specific ip address, you should access it by that ip address, e.g http://192.168.4.2:8000.

Huh. This surprised me a bit.

composer is correctly reporting the PHP version it's using. The problem is that it's not using the "correct" PHP interpreter.

The issue arises because of how you are installing composer.

Apparently by doing apk add composer another version of PHP gets installed (you can find it on /usr/bin/php8, this is the one on version 8.0.14).

Instead of letting apk install composer for you, you can do it manually. There is nothing much to install it in any case, no need to go through the package manager. Particularly since PHP has not been installed via the package manager on your base image.

I've just removed the line containing composer from the apk add --update command, and added this somewhere below:
