海外TECH	DEV Community	Structuring a CI/CD workflow in GitLab (Node.js example)	https://dev.to/lloyds-digital/structuring-a-cicd-workflow-in-gitlab-nodejs-example-2500	Structuring a CI CD workflow in GitLab Node js example Table of contentsWhat are pipelinesDevOps pipelinesWhat CI CD pipeline software to use Why did we choose GitLab Docker Technologygitlab ci yml filePipeline lifecycle exampleConclusion What are pipelinesIn computing pipeline refers to the logical queue that is filled with all the instructions for the computer processor to process in parallel It is the process of storing and queuing tasks and instructions that are executed simultaneously by the processor in an organized way This is different from the regular queue or stack data structures in computer science These data structures work in FIFO or LIFO approaches respectively This means literally First In First Out or Last In First Out principles no matter if working with elements instructions files or any other arbitrarily listable item DevOps pipelinesDevOps is a set of practices that combines software development and IT operations It aims to shorten the systems development life cycle and provide continuous delivery with high software quality DevOps is complementary with Agile software development several DevOps aspects came from the Agile methodology So if you re planning on having an agile work environment you must have good software foundations and automation processes set in place to achieve fast paced development and results If everything is done manually the environment would be rigid stiff and slow thus being the exact opposite of agile What is CI CD In software engineering CI CD or CICD is the combined practice of continuous integration and either continuous delivery or continuous deployment CI CD bridges the gaps between development and operation activities and teams by enforcing automation in the building testing and deployment of applications This would preferably shorten the gap between developers developing the project locally in their IDE and the project being published in their normal production environment either on public domain for clients or private domain for staging with other branches of the product development lifecycle backend frontend design QA testers It works on my machine ¯ ツ ¯Not only that we ve shortened the gap between the developer and productional environment but we ve also introduced an assurance that it will work within the productional environment The main component of CI CD is that we run install compilation build and test inside environment which mimics production Therefore we ve eliminated the chance of but it works on my machine happening Gitlab s CI CD flow other software uses mostly similar flow What CI CD pipeline software to use There are many options available to provide continuous delivery and integration in your software development lifecycle Some of the most popular CI CD tools are JenkinsCircleCIGitLabTeamCityBambooGitHub ActionsThe tool for the job is a personal preference and depends on which of these tools fit your project budget requirements language technology etc From this point on we will focus on GitLab s pipeline Why did we choose GitLab Well the choice was not a hard one GitLab is our default VCS and provides a rich set of features for CI CD pipelines leveraging the Docker technology The beauty of in house CI CD integration with your VCS is that the pipeline itself can be triggered upon various events from the developers The pipeline itself can be configured in a way that it triggers certain code blocks in all kinds of situations For example it can be triggered upon pushing to a certain branch or by providing some sort of specific trigger key within commit message it can be triggered upon Merge Requests upon the success of those merges etc This approach allows the DevOps engineer to configure the pipeline in a way that other software engineers mindlessly continue with their usual workflows and are completely oblivious to what s happening in the background This is great because now you need only one good engineer to configure and maintain it whereas the rest of the team organization does not have to bother with learning the technology inside out to use it Alongside being our default VCS and having great flexibility it can also be hosted on premise This way we are not using GitLab s servers also called runners but our own GitLab s pipeline will only charge you for computing time on their servers so we are saving some money But GitLab does have fast servers which are relatively cheap for min of computation That would be a good approach for big companies it would cost much less in the long run than configuring their cluster of runners Docker TechnologyDocker is a set of platform as a service products that use OS level virtualization to deliver software in packages called containers Containers are isolated from one another and bundle their software libraries and configuration files they can communicate with each other through well defined channels A Docker container image is a lightweight standalone executable package of software that includes everything needed to run an application code runtime system tools system libraries and settings The main difference between Docker and Virtual machines is that docker is running within its container virtualization engine whereas virtual machines virtualize whole guest operating systems In raw the docker allows you to simulate the production environment by replicating it beforehand and then containerizing it and publishing to hub docker com The important thing to consider is that you want to keep your docker image as minimalistic as possible because it does produce a heavy load for the machine using it You want to containerize only the service which you need to use and test eg for our backend stack we ve had to containerize PHP on Ubuntu and we ve added node npm and composer to the container That s it voila Now you d think that it s smart to ship other technologies to the same container for example using this container to test the frontend services would be pretty inefficient A much better approach is to use a different image for each stack you require because otherwise you will have unused software within your container Yeah I have it on my computer and server too so what s the deal The thing is for every job in the pipeline once started the docker fires a fresh container and boots it up If you want it to be fast you want it to be as minimal as possible Meaning that the backend will have only backend software on its image whereas the frontend will only boot up node js image without PHP and composer Separating services in different containers will help you speed up the pipeline overall The boot time is the biggest overhead that you get with additional software but only if you are using the self hosted runner Otherwise if you re running the pipeline on GitLab servers you need to download the image container at every step of the pipeline And if you have big images with unneeded software you will both download and boot longer and GitLab charges per minute of processing time meaning that you re twice as inefficient GitLab ci yml fileYAML is used because it is easier for humans to read and write than other common data formats like XML or JSON Further there are libraries available in most programming languages for working with YAML For a syntactic guidelines of YAML files Google is your best friend This file is the main configuration for your Gitlab pipeline Whenever you add this file to your project Gitlab will go through it whenever you change something within your project Here you will define the flow of your pipeline jobs stages what it will do when will it execute etc By default it will use shared GitLab runners where you ll have free minutes monthly by default The YAML file has a variety of keywords and control structures so you re able to define the what and when The content of the job within the script tag are the commands which will execute inside the docker container containing your application Here are some of the most commoontrol structures image defines which docker container will run for given job pipeline pulls from hub docker com stages define stages in which you can group your jobs Stages run serially one after another whereas jobs within the same stage run in parallel only defines when a job will run eg only on merge request artifacts defines which files will be shared between different jobs because the new container is initialized per job thus contents are lost unless specified with artifacts cache defines which files will be saved to the server for retrospectionscript defines what commands will be executed within the container OS level commands eg echo apt get install composer install xy These are some of the main control structures out of many for more you can check the documentation Pipeline lifecycle exampleThe pipeline starts from the gitlab ci yml file Here we ll analyze a simple pipeline configuration and what happens each step of the way We will consider the following pipeline for a front end project image node lateststages build run Job s namefirst job Define stage stage build What to run on the job script npm install artifacts paths node modulessecond job stage run script npm run start node test js artifacts paths node modules second job parallel stage run script echo I m running at the same time as second job As we can see we have two stages first stage installs the modules and has only one job The second stage kicks in if the first one finishes successfully and starts two jobs in parallel Gitlab s visualization of stages and jobsThe first thing that happens once you push your code is that GitLab scans the gitlab ci yml If there are no limitations in configuration the pipeline will be running on every push merge request and merge result Gitlab will then contact the runner aka the server which will be executing your pipeline Note if you have a single GitLab runner they will queue in FIFO principle Once the server responds it will start the docker executor with the image you ve specified In our case it is node latest If required you can specify a different image for each job If the server has the image cached it will start using it otherwise it will have to download it first Then once you have your container ready and booted up your project will be downloaded from your repository and once you re placed into the project root directory it will start executing commands you ve provided within the scripts list In our case it will install node modules Once the job is finished the artifacts will be uploaded so the next job using can download them back into the container Then the cleanup kicks in and the container is closed The second job is different but only slightly It will download the artifacts right after the project is downloaded so we have everything ready for scripts Once this job finishes it will again upload the modified artifacts for whoever might be using them next Other than that it is the same as the first job regarding the structure But the commands are slightly different and here as an example we run test js to test if our application is working Here are the contents of test js console log Hello from Node js console log new Date toUTCString console log Exiting Node js Here is the output from the second job And the last job is no different from the others it just proved to us that two jobs can indeed run in parallel ConclusionTo conclude the pipelines I would say that it is a must for any serious company to have these operations set in stone Human error is removed from the equation and monotonous tasks are automatized A good pipeline will also deploy the code to a staging server the company s internal server for testing quality assurance and collaboration but ultimately all productional deploys should be done manually by setting when key to manual in gitlab ci yml file Many many more things could be done within the pipeline such as benchmarking the app stress testing and others I might cover them in the next blog but until then what features do you think would make an awesome pipeline Lloyds is available for partnerships and
