Automate your Ibis eBook build process with this GitHub Action + Workflow |
https://dev.to/bobbyiliev/automate-your-ibis-ebook-build-process-no5
|
Automate your Ibis eBook build process with this GitHub Action Workflow IntroductionThe ibis build action action is a GitHub Action to automatically run your ibis builds on push events to your main branch IbisIbis is an open source PHP tool that lets you write eBooks in Markdown It was created by Mohamed Said who used it to generate his own eBook that he was writing at the time Ibis has allowed me to create multiple eBooks already However not everyone has PHP and Composer installed on their laptops so people who contribute to your eBook project might not be able to export the PDF of your eBook after their changes This is why I decided to create a GitHub Action that would let you automatically generate your Ibis builds directly on GitHub without having PHP installed on your laptop UsageIn order to automatically build your Ibis PDF files create a directory called github workflows and add a fill called ibis yml with the following content name Ibis eBook Generationon push branches mainjobs build runs on ubuntu latest steps uses actions checkout main with fetch depth name Build Ibis Export Files uses bobbyiliev ibis build action main env GITHUB TOKEN secrets GITHUB TOKEN IBIS PATH IBIS BRANCH main EMAIL bobby bobbyiliev com COMMIT MESSAGE Updated Ibis Exorted Files Environment VariablesThis is the list of the environment variables that you need to keep in mind GITHUB TOKEN Required for permission to tag the repo You can leave it as it is IBIS PATH The path to the Ibis init folder By default it is but if you have a custom location make sure to update itIBIS BRANCH The Branch that the Ibis exported files will be commited and pushed to Default is main EMAIL The email address that the commit will be associated with COMMIT MESSAGE The commit message WorkflowThe ibis build action GitHub Action does the following things once added to your repository Every time you push to main or merge a PR to main this workflow takes palce On push or merge the action will Clone the repositoryRun the ibis build commands including the sample buildsStage and commit the new exported eBook files to the specified branchPushes tag to GitHubThis will provide you with your eBook PDF file generated and stored in your repository s content folder Ebook Projects using the ibis build action GitHub action Introduction to DockerIntroduction to Git and GitHubIntroduction to Bash ScriptingIntroduction to SQLLaravel tips and tricks Alternative approachAs brought up to my attention recently by Roberto B in case that you need more flexibility about managing the PDF rather than using the ibis build action GitHub action you can produce an artifact instead Here is an example GitHub workflow provided by Robert which would do the same build but store the PDF as an artifact Ibis artifact workflow ConclusionIbis is a great tool and in case that you are planning to write an eBook make sure to give it a try By using the ibis build action GitHub Action you can automate your eBook PDF generation on each push to a specific branch and always have an up to date export of your eBook If you like this make sure to follow me on Twitter bobbyiliev I hope that this was helpful |

Essential Guide to Linux Servers IntroductionIntroductionA bit of background I ve been using Linux both on my desktops and servers since the early s I ll try to distill what I learned over those years into a simple and easy to follow guide in a way that I would approach things if I had to start from scratch I ll try to make things friendly towards new users you should be able to follow the guide even if you have very little or even no experience with Linux We re going to start by going through the process of setting up a Linux VPS and then build upon that So why even bother instead of going serverless Well first there s no such thing as serverless there are only servers controlled by you and servers controlled by someone else In the long term trading off that control tends to come at a huge price By learning to run things yourself even if you do end up going serverless on some projects you ll have a much better and deeper understanding of those trade offs limitations pitfalls and lock ins Easy scaling promises for the most part are just that promises Even if they weren t it s extremely unlikely that you ll really need them A lot of people would be very surprised how much you can get from a single Linux box Considering what you get in return running your own VPS is really cheap you can get a nice KVM based VPS for a few bucks a month But having full freedom and control over your server is priceless With serverless options you ll always be severely limited in what you can do and what you can depend upon and even that limited set of dependencies is subject to change at any time In the next post we re going to make a few important decisions about our new server Note This is part of the Essential Guide to Linux Servers in progress series You can follow me here or on Twitter for updates |

Jelastic and Docker containers A marriage made in the cloud for developersInto containers No Well you should be Containers like Docker can help you automate and speed up your development process but there s more to the story than that You see it s not just developers who benefit from containers businesses that use cloud hosting do too So let s explore how Jelastic and Docker containers can make your life easier and your costs lower starting with the basics Note this article assumes familiarity with both Jelastic and Docker Why Choose JelasticIf you re new to cloud hosting or simply not that familiar with Jelastic you may be wondering why Jelastic is worth your time Well for starters it offers one of the most fully featured DevOps capabilities on any public cloud platform Couple that with its tight integration with Dockerーwhich is quickly becoming one of today s hottest technologiesーand it s easy to see why Jelastic is so attractive to application developers It also doesn t hurt that Jelastic comes from a company whose history and expertise spans more than years That kind of deep domain knowledge matters More than anything else though what makes Jelastic such a great choice for developers is its usability UI and ease of management EM After all nobody wants to spend their time managing their host they want to focus on developing applications that will help their business grow while keeping IT costs low That s why we built our user interface around our customers we think we have what many would call a killer UI which means your developer team can concentrate less on managing hosts and more on building scalable apps Docker SupportIf your enterprise is already using Docker on premise or even in a public IaaS cloud you can still leverage Jelastic s powerful platform With Jelastic s Docker integration you have seamless access to native containerized applications across multiple environments both private and public from a single portal Since everything runs within a system container you don t need a full virtual machine for each application anymore This drastically reduces overhead costs associated with VMs and makes maintenance easier That way any changes that happen inside one of these containers do not affect anything else running in them on different hosts Think of it as one address space per container where all your containers will share OS resources yet remain completely isolated from one another Plus since VMs are hardware dependent keeping track of their version updates can be tricky at times while with Docker based applications it is almost effortless because they run inside kernel space alongside host OS What Is Docker Docker is a technology that allows you to develop run test and deploy applications by using containers Containers work at a higher level than VMs because they don t have a virtualized operating system In fact since each container runs its own application with its own set of libraries it s almost as if each application has its own instance of an operating system That helps to keep your data isolated from other applications running on a single hostーeven if those other applications were written in different languages or come from different sources How Does It Work Jelastic has support for running Docker containers natively within its platform It is important to note that Jelastic is not a container management solution but rather it runs Docker inside system level containers on top of KVM virtualization engine The point of doing so is increased performance since these internalized containers share host OS kernel thus relying on fewer resources Benefits of Running Containers on Jelastic Platform•Running Docker Containers on Hidora is optimized with vCPU RAM and Storage resources •Jelastic takes care of all hardware failures allowing them to be removed from developers focus •Developers only need to consider how many instances they want for their applications and can balance their needs with resource availability This is highly flexible as instances auto scale up or down based on resource demands •Both small and large development teams will enjoy uniform experience across different deployments of applications across various platforms such as NET Core NodeJS Java PHP Python Ruby and more without any VM sprawl •Using a built in Load Balancer that distributes traffic among all available services allows developers to deploy scalable distributed applications easily without additional efforts •Replicated instance groups ensure zero data loss in case of instance failure making application fault tolerance seamless •Auto Scaling groups guarantee efficient usage of server capacity by balancing load distribution requests among different servers rather than overloading just one system However even if auto scaling is not required currently it is ready when needed |

Road to DevOps – How Tools Like AWS CDK Help with DevOps Transition |
https://dev.to/brightdevs/road-to-devops-how-tools-like-aws-cdk-help-with-devops-transition-3k7i

Road to DevOps How Tools Like AWS CDK Help with DevOps TransitionIt s obvious that DevOps is a buzzword these days If you are somehow connected with software development the DevOps culture could possibly jump right on your face from your fridge You haven t heard it I don t believe you but if that s the case no worries you will Sooner or later The Definition of DevOpsI could possibly write a book trying to describe everything that one should know about DevOps how cool it is and why everyone should shout out DevOps slogans with the same frequency as some Agile mantras Yeah most probably it wouldn t be a bestseller so I won t Instead I would present a short yet meaningful definition from AWS DevOps is the combination of cultural philosophies practices and tools that increases an organization s ability to deliver applications and services at high velocity evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes How does it sound Simple yet descriptive right Sure but what does it really mean for a software development team that would like to boost up velocity and go one step ahead on the delivery quality path I have my own perspective on DevOps which grew while working with different teams in different environments on a wide spectrum of projects DevOps culture is about getting out of comfort zone cross team collaboration and putting impact on a feedback loop all that with the help of modern DevOps toolset And that s what this story is really about Road to DevOps the story of a DevOps engineer and a common antipattern BackgroundNow let s pay a visit to Dr Emmett Lathrop Brown and make use of that fancy DeLorean DMC to jump into the past for a second Someone is waving at us That s a younger version of me Meet Michał the SysOps He is working in a big corporation with bare metal servers and some virtualisation in place Oh and he has keys to data center And a winter wool hat for hours spent there with all the fans and air conditioning on Back then my main problem was to automate repetitive work on the copious numbers of virtual machines and bare metals hosting business applications on some enterprise Linux distributions or other Unix family systems like IBM AIX It was relatively easy sometimes challenging but mainly easy with some edge cases to be covered with custom scripts and dirty hacks that should never go live to production I had some useful background for that job The very basic concepts of programming data structures and algorithms were injected into my fertile brain back then It was done in the lower secondary school by my IT teacher she was able to see that small IT sparkle in me and a few colleagues That knowledge was constantly growing both in school and at home Besides hanging out with friends yes I m from the generation that used to play outside I was creating websites about Worms and Quake with HTML PHP and some Javascript Later it evolved into Python and Django I used to have a self built server in my drawer made of an old laptop motherboard Gentoo Linux was sitting there if someone is not familiar with it It s a distribution that forces you to configure everything from scratch by yourself hence my main hobby was to compile Linux kernel with a hilarious frequency It was useful though drawer served as a heater during winter So automation scripting Perl Bash Sed Awk Python Linux Unix Let s add Ansible Chef to the stack some monitoring Nagios Sensu VCS and finally Docker with Docker Swarm Not to forget about load balancing with Nginx and HAProxy That was me as a SysOps back then DevOps EngineerOk we are jumping into DeLorean once again Oh Hi Marty When did you join us Never mind We travelled in time a few years forward Here he is Michałwith his shiny Apple Macbook working from home Yes from home Why you ask That s because now he works in the cloud Now Michałis a DevOps Engineer serving as a catalyst to software development How cool is that huh So what changed Now everything is done with VCS CI CD is in place and I m responsible for the pipelines and how optimal they are I m working with software being developed by frontend and backend devs New programming languages and frameworks to support and know their gotchas Managed services rather than self hosted ones Despite being more expensive it s easier to have something supported externally without the need of maintaining an internal team for some software component support Cloud is new normal Mostly AWS some GCP some Azure and some edge cases like Hetzner Cloud or Digital Ocean Well I had to learn quite a lot regarding the cloud A few new certifications loads of whitepapers and even more tries and errors Docker is the new normal And Kubernetes with all its sparkles and problems as a remedy for software at scale Developers need dynamic environments on demand It s best to have per pull request env for QA to check new features The challenging topic for DevOps team Tickets lots of tickets from PMs and developers And due dates with impatient stakeholders And the Terraform How could I forget that Now as we live in clouds these days it s wise to have Infrastructure as Code IaC in place No more clickology a new level of automation and ability to reuse common snippets And yes the code for infrastructure also lives in Git with CI CD So again what changed Can you see what I m trying to say here Let s move back to the DevOps definition Clearly there are some new shiny DevOps tools in game and for sure they serve software development and help to deliver apps with a higher velocity at a better scale But it doesn t really sound like we are aligned with the whole DevOps story What definitely is different is that now I work as a DevOps Engineer climbing the DevOps career path and raising seniority level How could I describe my daily work in a few words I was working for developers not with them building infrastructure and CI CD pipelines with a modern DevOps toolset reacting to tickets with the use of knowledge that was sealed in the DevOps team It was neither of my interest to wear developers shoes nor developers will to understand what my team does and how does the infrastructure hosting software they write works Not to mention any form of contribution both ways And this is the most common scenario of how a DevOps role looks like in many teams companies and the most common scenario of how do people start working as a DevOps Engineer Also confronting this with the DevOps definition it s the most common DevOps antipattern among the IT world DevOps Engineer revisited A short novel about getting out of my comfort zone Last journey DMC can you please move us to the more or less present time Thank you but where is Marty Most probably he s got some business in the future Where are we now We are in Bright Inventions Hurray I ve managed to pass the recruitment process with Ula examining my attitude and team fit and somehow got through difficult yet right on the nose questions asked by Piotr I m pretty happy that I could finally be able to mostly focus on one product and get rid of context switching I used to deal with previously Actually I m satisfied with the fact that I ll vendor lock myself a bit with AWS mainly because this is my field of expertise and I have the most experience with AWS services After short onboarding I should be ready to work This environment is familiar to me and also the toolset right Indeed mostly One simple thing that is so much different in the bigger picture AWS CDK So what is the CDK According to AWS it s is an open source software development framework to define your cloud application resources using familiar programming languages Pretty neat right At first sight it seems like a substitute to Terraform Now a very important piece of information that seems to be a clue to the whole story I m the first DevOps Engineer at Bright Inventions Why is this important you may ask Well as I mentioned the team was already using everything I was familiar with The software is living in the cloud and the development lifecycle needs a good velocity So how actually the team did manage to go that far without a DevOps engineer Well besides having some really bright minds on board truly open minds they did something that was the most comfortable and well known to them They made use of TypeScript to spawn the whole infrastructure with the help of AWS CDK Having documentation in place for all the CDK constructs and being able to work with a programming language they are familiar with it was possible for them to do what they needed in the AWS cloud I mentioned getting out of my comfort zone Firstly it was for sure not easy for the developers to work with AWS It s a wide complicated ecosystem with different gotchas in many places It requires rather a wide domain knowledge to do things both right and secure Not to forget about being cost effective But CDK helped with that a bit being kind of a proxy to AWS services with TypeScript constructs in place Documentation covering all the parameters and methods is a well known ground for developers using them Secondly me and CDK That was something that bothered me for some time It s just a tool doing the same thing differently they say However there was something unusual for me in the path Bright Inventions took here It took a few weeks for me to get to know CDK its interactions with underlying CloudFormation and to learn something new TypeScript It was refreshing but definitely out of my cosy status quo I grew using Terraform While I was familiar with some programming languages not being a part of software development per se resulted in the necessity to learn good practices and how to do things just right All in all fun things happened here at Bright Inventions My mindset changed a bit I started to think more like a developer than SysOps I actually am It gave me a wider perspective on the software I m working with with a deeper understanding of application code and how to work with developers efficiently I ve learned a lot about code quality good practices regarding programming languages and code review Of course I knew about that in theory Practising these guidelines was not an everyday basis especially having in mind that previously my level of dev lt gt ops collaboration was from minimal to none I even feel comfortable with contributions to the applications codebase I ve noticed something that seems to be the most crucial part of DevOps culture developer empowerment Developers feel free to contribute to infrastructure They have an understanding of how infrastructure works and how to use AWS services properly Of course it doesn t mean that DevOps engineers can be switched for developers Making the most of AWS requires some domain knowledge about service dependencies networking security and how do they scale up and scale out It means that it s much easier to understand the infrastructure and its current state with tools like CDK and its documentation Most importantly something I saw in Bright Inventions with a naked eye is that instead of raising a ticket to DevOps e g adding S bucket SQS or Lambda function waiting a week for closing it developers do these contributions to the infrastructure themselves with pull requests and review requests from DevOps Engineer or anyone familiar with a particular subject Summary the DevOps definition revisitedRemember my definition of DevOps That s the story of how I came to that DevOps mindset is all about collaboration and feedback loop Thanks to tools like AWS CDK one can both introduce so important dev empowerment and move the quality of work done by SysOps DevOps Infrastructure engineers to a whole new level As an effect we destroy the silos which slows down the development process so much Obviously it s a good moment to pinpoint some disadvantages of CDK It s a tool written by AWS for AWS hence we get another vendor lock in here It s great for its own ecosystem however not ideal There are some major drawbacks of using CloudFormation which I m aware of But it s not my intention to praise this particular tool but to draw attention to the philosophy CDK follows Luckily there are various tools on the market that try to solve problems mentioned above with a different level of maturity like Pulumi or cdktf that allows you to use familiar programming languages and CDK constructs to define cloud infrastructure and provision it through HashiCorp Terraform That one is a brilliant solution that connects the advantages of CDK and the great power of Terraform and its huge base of providers along with a friendly community I sincerely encourage all software development teams and DevOps teams that live in antipatterns I used to live in to look into this attitude and try to implement it even experimentally Adapting to the new working culture takes some time and effort on every side of the equation but the effect can be surprisingly satisfying for everyone By MichałLemke DevOps Engineer Bright Inventions

Apple's self service program will let you repair iPhones and Macs yourself |

Apple x s self service program will let you repair iPhones and Macs yourselfApple just became much friendlier to do it yourself repairs The company is launching a Self Service Repair program that will let you repair products yourself using official Apple parts and tools The option will be available in the US in early later that year for other countries and will initially give the resources to fix an iPhone or iPhone you re looking at iFixit s iPhone Pro teardown above with M based Macs eligible soon afterward The first quot phase quot of Self Service Repair will focus on core components like the battery camera and display with other parts eligible later Apple will ask customers to review a repair manual and then order relevant parts through a Self Service Repair Online Store The company didn t say how much parts would cost but did offer credit to customers who return used parts for recycling Not surprisingly Apple stressed that the program was meant for people with experience repairing electronics The quot vast majority quot of people were still better off getting service from professionals whether at Apple stores or authorized providers nbsp The company didn t say what prompted the openness to self servicing However it may be a matter of government pressure The White House the Federal Trade Commission and multiple states have backed right to repair measures that could force Apple and others to allow customer maintenance This theoretically heads off some of the major complaints by letting any skilled person fix a device themselves without resorting to unofficial parts There are lingering questions Will the part pricing be competitive enough to make Self Service Repair a viable alternative to professional help And will Apple tweak its product designs to make these repairs more practical While there are signs of these tweaks between a relaxed policy on iPhone display repairs and easy to remove MacBook Pro batteries we wouldn t expect simple fixes in the near future Developing |
