海外TECH	DEV Community	Set up PHP QA tools and control them via make [Tutorial Part 5]	https://dev.to/pascallandau/set-up-php-qa-tools-and-control-them-via-make-tutorial-part-5-2lh9	Set up PHP QA tools and control them via make Tutorial Part This article appeared first on at Set up PHP QA tools and control them via make Tutorial Part In the fifth part of this tutorial series on developing PHP on Docker we will setup some PHP code quality tools and provide a convenient way to control them via GNU make FYI Originally I wanted this tutorial to be a part of Create a CI pipeline for dockerized PHP Appsbecause QA checks are imho vital part of a CI setup but it kinda grew too big and took a way too much space from well actually setting up the CI pipelines All code samples are publicly available in my Docker PHP Tutorial repository on Github You find the branch with the final result of this tutorial at part php qa tools make docker All published parts of the Docker PHP Tutorial are collected under a dedicated page at Docker PHP Tutorial The previous part was Run Laravel on Docker in and the following one is Use git secret to encrypt secrets in the repository If you want to follow along

IntroductionCode quality tools ensure a baseline of code quality by automatically checking certain rules e g code style definitions proper usage of types proper declaration of dependencies etc When run regularly they are a great way to enforce better code and are thus aperfect fit for a CI pipeline For this tutorial I m going to setup the following tools Style Checker phpcsStatic Analyzer phpstanCode Linter php parallel lintDependency Checker composer require checkerand provide convenient access through a qa make target The end result will look like this FYI When we started out with using code quality tools in general we have used GrumPHP and I would still recommend it We have only transitioned away from it because make gives us a little more flexibility and control You can find the final makefile at make application qa mk CAUTION The Makefile is build on top of the setup that I introduced in Docker from scratch for PHP Applications in so please refer to that tutorial if

What s going on here We use Symfony Component Console Input InputOption in our App Commands SetupDbCommand and the code doesn t fail because InputOption is defined in thesymfony console package that is atransitive dependency of laravel framework see the laravel framework composer json file I e the symfony console package does actually exist in our vendor directory but since we also use it as a first party dependency directly in our code we must declare the dependency explicitly Otherwise Laravel might at some point decide to drop symfony console and we would be left with broken code To fix this I runmake composer ARGS require symfony console which will update the composer json file and add the dependency Running composer require checker again will now yield no further errors root var

individually being able to run individually is still great if a tool fails though A trivial approach would be a new target that uses all individual tool targets as preconditions PHONY qaqa phpstan

sphpstan done took scomposer require checker done took s The execute function We ll make this work by suppressing the tool output and using a user defined execute make function to format all targets nicely Though function isn t quite correct here because it s rather a multiline variable defined via define endef that is then invoked via the call function File application qa mk call with NO PROGRESS true to hide tool progress makes sense when invoking multiple tools together NO PROGRESS falseifeq NO PROGRESS true PHPSTAN ARGS no progressendif Use NO PROGRESS false when running individual tools On NO PROGRESS true the corresponding tool has no output on success apart from its runtime but it will still print any errors that occured define execute if NO PROGRESS false then eval EXECUTE

END date s RUNTIME END START printf took RUNTIME s n echo OUTPUT printf n exit fi fiendefthe NO PROGRESS variable is set to false by default and will cause a target to be invokedas before showing all its output immediatelyif the variable is set to true the target is instead invoked via eval and the output iscaptured in the OUTPUT bash variable that will only be printed if the result of theinvocation is faultyThe tool targets are then adjusted to use the new function PHONY phpstanphpstan Run static analyzer on all application and test files call execute PHPSTAN CMD PHPSTAN ARGS

speed up the process by running the tools in parallel with the j flag for Parallel Execution make j qa NO PROGRESS truephpstan phplint composer require checker phpcs done took sdone took sdone took

sphplint done took scomposer require checker done took sphpcs done took sSince this is quite a mouthful to type we ll use a helper target qa exec for running the tools and put all the inconvenient to

output sync target qa exec NO PROGRESS true PHONY qa execqa exec phpstan phplint composer require checker phpcsFor the number of parallel processes I use nproc works on Linux and Windows resp sysctl n hw ncpu works on Mac to determine the number of available cores If you dedicate less resources to docker you might want to hard code this setting to a lower value e g by adding a CORES variable in the make env file Sprinkle some color on topThe final piece for getting to the output mentioned in the Introduction is the bash coloring To make this work we need to understand first how colors work in bash This coloring can be accomplished by adding a e or at the beginning to form an escape sequence The escape sequence for specifying color codes is e COLORm COLOR represents our numeric color code in this case via Adding colors to Bash scripts E g the following script will print a green text printf mThis text is green m So we define the required colors as variables and use them in the corresponding places in the execute function bash colorsRED mGREEN mYELLOW mNO COLOR m Use NO PROGRESS false when running individual tools On NO PROGRESS true the corresponding tool has no output on success apart from its runtime but it will still print any errors that occured define execute if NO PROGRESS false then eval EXECUTE IN APPLICATION CONTAINER else START date s printf s if OUTPUT eval EXECUTE IN APPLICATION CONTAINER gt amp then printf GREEN s NO COLOR done END date s RUNTIME END START printf took YELLOW RUNTIME s NO COLOR n else printf RED s NO COLOR fail END date s RUNTIME END START printf took YELLOW RUNTIME s NO COLOR n echo OUTPUT printf n exit fi fiendefPlease note that i did not include the tests in the qa target I like to run those separately because our tests usually take a lot longer to execute So in my day to day work I would run make qa and make test to ensure that code quality and tests are passing make qaphplint done took sphpcs done took scomposer require checker done took sphpstan done took s make testPHPUnit StandWithUkraine Time Memory MBOK tests assertions Further updates in the codebaseI ve also cleaned up the codebase a little in branch part php qa tools make docker and even though those changes have nothing to todo with QA tools I didn t want to leave them unnoticed removing unnecessary files styleci yml package json webpack mix js removing unused values from the env example filerun a composer update to get the latest Laravel versionadd a show help script to the scripts section of the composer json file that references the Makefile see also this discussion on Twitter scripts show help make scripts descriptions show help Display available make commands we use make instead of composer scripts replace docker compose with docker compose to use compose vFor some reason the last point caused some trouble because Linux and Docker Desktop for Windows require a T flag for the exec command to disable a TTY allocation in some cases Whereas on Docker Desktop for Mac the missing TTY lead to a cluttered output staircase effect Thus I modified the Makefile to populate a DOCKER COMPOSE EXEC OPTIONS variable based on the OS Add the T options to docker compose exec to avoid the panic the handle is invalid error on Windows and Linux see DOCKER COMPOSE EXEC OPTIONS T OS is defined for WIN systems so uname will not be executedOS shell uname ifeq OS Windows NT Windows requires the exe extension otherwise the entry is ignored see SHELL bash exeelse ifeq OS Darwin On Mac the T must be omitted to avoid cluttered output see issuecomment DOCKER COMPOSE EXEC OPTIONS endifAnd use the variable when defining EXECUTE IN CONTAINER in make docker mkifeq EXECUTE IN CONTAINER true EXECUTE IN ANY CONTAINER DOCKER COMPOSE exec DOCKER COMPOSE

by now don t hesitate to leave a comment You should now have a blueprint for adding code quality tools for your dockerized application and way to conveniently control them through a Makefile In the

海外TECH	DEV Community	How Azure Works?	https://dev.to/pranambhat/how-azure-works-5c27	How Azure Works Azure is Microsoft s public cloud platform Azure offers a large collection of services which includes platform as a service PaaS infrastructure as a service IaaS and managed database service capabilities However what exactly is Azure and how does it work Azure like other cloud platforms relies on a technology known as virtualization Most computer hardware can be emulated in software Computer hardware is simply a set of instructions which are permanently or semi permanently encoded in silicon Emulation layers are used to map software instructions to hardware instructions Emulation layers allow virtualized hardware to execute in software like the actual hardware itself Essentially the cloud is a set of physical servers in one or more datacenters The datacenters execute virtualized hardware for customers So how does the cloud create start stop and delete millions of instances of virtualized hardware for millions of customers simultaneously To understand the servers let s look at the architecture of hardware in the datacenter Inside each datacenter there s a collection of servers sitting in server racks Each server rack contains many server blades and a network switch These provide network connectivity and a power distribution unit PDU which creates power Racks are sometimes grouped together in larger units known as clusters The server racks or clusters are chosen to run virtualized hardware instances for the user However some servers run cloud management software known as a fabric controller The fabric controller is a distributed application with many responsibilities It allocates services monitors the health of the server and the services running on it and heals servers when they fail Each instance of the fabric controller is connected to another set of servers running cloud orchestration software typically known as the front end The front end hosts the web services RESTful APIs and internal Azure databases which are used for all functions in the cloud For example the front end hosts the services that handle customer requests The requests allocate Azure resources and services such as virtual machines and Azure Cosmos DB First the front end validates and verifies if the user is authorized to allocate the requested resources If so the front end checks a database to locate a server rack with sufficient capacity which instructs the fabric controller to allocate the resource Azure is a huge collection of servers and networking hardware which runs a complex set of distributed applications These applications orchestrate the configuration and operation of virtualized hardware and software on those servers The orchestration of these servers is what makes Azure so powerful With Azure users don t have to maintain and upgrade their hardware as Azure does this behind the scenes	2022-07-01 06:11:07
