Optimizing Rust container builds

I'm a Rust newbie, and one of the things that I've found frustrating is that the default docker build experience is extremely slow. As it downloads crates, then dependencies, then finally my app - I often get distracted, start doing something else, then come back several minutes later and forget what I was doing

Recently, I had the idea to make it a little better by combining multistage builds with some of the amazing features from BuildKit. Specifically, cache mounts, which let a build container cache directories for compilers & package managers. Here's a quick annotated before & after from a real app I encountered.

Before

This is a standard enough multistage Dockerfile. Nothing seemingly terrible or great here - just a normal build stage, and a smaller runtime stage.

Нагрузочное тестирование c Yandex.Tank и JMeter

На этой странице описывается процесс настройки нагрузочного тестирования внешних ресурсов.

Кратко

Для тестирования поведения сервиса под нагрузкой используется утилита Yandex Tank.

Танку можно указать патроны (HTTP-запросы, которые будут отправлены на целевой сервер) и расписание (количество запросов в секунду к целевому серверу в каждый момент времени стрельб, а также продолжительность стрельб). Также к танку можно подключить плагин мониторинга, позволяющий снимать показатели (например, количество свободной памяти или загрузку процессора) с целевого сервера.

Debug your PHP in Docker with Intellij/PHPStorm and Xdebug

For your local dev, create a Dockerfile that is based on your production image and simply install xdebug into it. Exemple:

FROM php:5

RUN yes | pecl install xdebug \
&amp;&amp; echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" &gt; /usr/local/etc/php/conf.d/xdebug.ini \
