Docker, along with Docker Compose are the most used tools under the DevOps category, according to The State of Developer Ecosystem 2019 survey by JetBrains. Chances are if you're using Docker/Docker Compose for deployment, you'll most likely be using them for local development as well. If you only use Docker for deployment but a virtual environment for local development, you may want to look into using Docker for development to reduce the parity between dev/prod environments, as suggested in the Twelve-Factor Methodology.
Most of the web apps I build eventually end up needing a background worker. There will be some slow or heavy task that really should run independently, like an integration with a third-party server, a web scraper, PDF creation, something.
So you want to start testing your code? Good choice. Testing is a great way to make sure nothing breaks in deployment, and Jenkins makes it easy to automate this process.
Nowadays, putting shiny new applications in containers seems to be the way of the future, and for good reason. They offer platform portability, hardware efficiency, and enhanced security. In this tutorial, we are going to take a very simple Flask API, put it in a Docker container, and then test it out using Postman.
With the shift to Cloud-first and the rise of managed infrastructure and orchestrations such as EWS, Azure AKS or GCP clusters the application landscape needs to prepare and adjust itself to match newly rising requirements. This is for such nothing new nor unknown, but acknowledging this fact is one and probably the first important step.

There are numerous benefits of delivering an application as container packages to Kubernetes but at the same time, the process of app containerization and the subsequent app deployment to Kubernetes can hit many roadblocks. Since the idea of using Kubernetes and containers for app delivery is fairly recent, the transition from traditional delivery systems to these modern delivery systems is a bumpy ride.
Sometimes you just want to dip your toe into a potentially deep and complex subject. Maybe you only have 10 minutes to spare and you want to get something up and running quickly.
Many of us using Docker to make our lives easier have ran into the issue of conflicting ports due to running more than 1 docker container. It’s easy to get bogged down into changing config files and squander an entire afternoon. I intend to write this article as a reminder to my future self whenever I need to set up multiple instances of docker container on a single machine.
It never fails that the CNCF seem to always be cooking up something interesting in their ecosystem. In my free time, I always seem to find myself in a habit of playing in the Sandbox to see what new cutting edge tools I can add to my collection. It is my goal today to introduce you to a project at the Sandbox stage known as "Buildpacks".
During the quarantine period, I started an Italian tech live show on YouTube and a podcast on Spotify and Anchor.fm with some of my friends. The show’s called Schrödinger Hat.
JavaScript based face recognition with Face API and Docker.he
Hi Everyone, Hope you all Programming geeks are doing well. In today's modern Software Industry, there are two types of engineers:
Today, we no longer talk about development and operations in isolation. DevOps actively combines these two, which is an essential factor in the modern software lifecycle. Along the way, Docker containers have also become popular due to the benefits they offer for DevOps. Containers affect DevOps mainly in two ways.
How to develop software in containers
At Debricked we have been using Symfony for our web backend for a while now. It has served us very well and when they announced the Messenger component back in Symfony 4.1, we were eager to try it out. Since then we have used the component for asynchronous queuing emails.
What is Deno? Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust.
Using Docker Compose in development with creature comforts for developers.
While developing a web application, a common method of calling the application from a local machine is through //localhost:x ports, which essentially means that we are required to expose several ports to access different modules of the application. In the article below, we will go through the method of using Reverse Proxy to call an application and the benefits of using it.
Kubernetes deployments are becoming even more complex but Helm is a good solution to bridge this deployment complexity and package Kubernetes applications
A universal truth we’ve experienced as both an IT software vendor and as an application delivery team is that application owners are constantly trying to deliver better software faster.
How to configure PhpStorm and Xdebug to run PHP in Docker for php-fpm, cli and daemon worker processes in 2022.
Back-end engineering nowadays may require the integration of multiple services. It is painful for engineers to install many services in their local development environment. Docker has provided an easier way to do this, but it will still require some scripting outside our code. It also has not exactly had a perfect solution if we wanted to test smaller functions or classes instead of the whole service. This problem has been addressed by Testcontainers [1].
Setting up a dockerized container to launch project setups that'll help deploy and run smart contracts.
Ever since Docker went live in early 2013 it’s had a love-hate relationship with programmers and sysadmins. While some ‘experienced’ developers that I’ve talked to have a strong dislike for containerization in general (more on that later), there’s a reason why a lot of major companies including eBay, Twitter, Spotify and Lyft have reportedly adopted Docker in their production environments.
7 Strategies and associated tools for your container security workflows.
A quick and direct method of running up a MySQL database backup.
I still remember February 2018 very well. Many people were in a really bad mood when it came to Blockchain or Distributed Ledger Technology (DLT), mainly because the price of most cryptocurrencies made a nose dive and the Disillusionment started.
This is the second installment of my 'How I built' trilogy detailing the build process of all 3 of my clusters. Read the first here.
Open-Source Web UI for Apache Kafka
The integration of Docker and Kubernetes makes Zalenium an appealing choice for setting up Selenium-based infrastructure.
In this guide, we are going to use Docker to configure Jenkins and Tomcat to achieve Continuous Integration/Continuous Deployment.
When I just started developing PHP applications I used Mamp or Xamp to set up a local Lamp stack. Later this became Vagrant in combination with VirtualBox and eventually Docker.
In this post, we provide a list of the 10 best Kubernetes CI/CD tools that will help you decide which tool is best for your Kubernetes CI/CD pipeline.
How I automated the process of service deployment for a console application after issues caused due to multiple configuration environments.
Make your containerized CI environments truly useful by accelerating your Docker builds
In an ideal world, Docker containers should be ephemeral without any reliance on external storage. In the microservice world, this is achievable when services are connecting to external databases, queues, and other services.
There are key differences between GKE and EKS. While EKS is a market leader, read more to find out why GKE can give EKS a run for its money.
As software development (both frontend and backend) is moving towards automation, good knowledge and experience about the Docker could be very valuable for your career.
Whenever you are learning some new technology, I believe that you should start from very basics.

13 different things that you can learn today if you want to be a tech entrepreneur or a better engineer to make an application and ship it to your customers!
We use different Continuous Integration tools in our projects. One of them is TeamCity software. A pipeline for TeamCity can be configured easily and has two steps, such as run tests and build a docker image for further deployment. However, I needed to run Postgres before running tests. I made a research, I read the documentation and this article may be useful to close a gap for team city’s documentation.
The benefits that come with using Docker containers are well known: they provide consistent and isolated environments so that applications can be deployed anywhere - locally, in dev / testing / prod environments, across all cloud providers, and on-premise - in a repeatable way.
If you've been into software or web development for any amount of time, chances are that you at least heard of Docker. Maybe you're like me and have avoided using it because it seems complicated or difficult to set up.
It's no secret that MariaDB has become a popular database solution for developers over the past decade. Why? Well, one could argue that it's largely because it's open source and relational. So, for developers, that basically means it's free, and we get the gist of it. But that really only begins to scratch the surface.
This blog post shows how you can debug a simple Node.js application running in a Docker container. The tutorial is laid out in a fashion that allows you to use it as a reference while you’re building your own Node.js application and is intended for readers who have prior exposure to JavaScript programming and Docker.
For the past few hours, I've been working on dockerizing a Nuxt.js server-side rendering app to be deployed to AWS Elastic Container Service (ECS). I hit a stone wall when environment variables are not properly injected on runtime on ECS.
In many blockchain platforms such as Ethereum and Bitcoin, data confidentiality is a kind of excluded item in their blockchain framework. In these distributed blockchain platform transactions are executed in every participant node in the network. So, every transaction in the network can be visible to all the peers. The ledger update process through all the endorsed peers and has to reach an agreement among all before it committed successfully to the ledger. So, in this scenario creating a private record and comprises within a certain group of participants in the network is a complete “No”.
Buildah is a tool for building OCI-compatible images through a lower-level coreutils interface. Similar to Podman, Buildah doesn't depend on a daemon such as Docker or CRI-O, and it doesn't require root privileges. Buildah provides a command-line tool that replicates all the commands found in a Dockerfile. This allows you to issue Buildah commands from a scripting language such as Bash.
This is the first of the 'How I built' trilogy detailing the build process of all 3 of my clusters.
There are 3 steps that Kubernetes uses to enforce security access and permissions are: Authentication, Authorization and Admission. In this article we are going to consider Authentication first.
This tutorial is for the ones who want to try out the Kubernetes installation on CentOS.
The advent of Cloud and Container technology ushered a new era in distributed computing at “planet scale” which was unheard of and unimaginable just a decade ago. Another interesting movement was brewing up a decade ago which bolstered delivering these complex solutions at high speed and accuracy, DevOps.
In this step by a step blog post, that illustrates how to integrate Python Flask applications with Docker and run them in a Kubernetes cluster, we will cover the following topics:

I do test automation for ONLYOFFICE document editors, and our team uses Docker for lots of tasks. It’s difficult for me to imagine how to work without it and not suffer performance losses.
Kubernetes opens up the potential for better application management and deployment automation.
Problem - How many times have we faced this problem of worrying about cleaning up after running test cases. When some of our test cases run, they might add data to our database or add files to our directory which we don’t want to worry about every time.
There is often the need to check whether your production system is working as expected. Playwright is a great way to test if everything is going to plan.
In this post my plan is to create open tcp port scanning tool, use GO and worker pool to make it very fast. Expose it via REST resource, containerise and deploy
In this article we will learn about how to create docker or OCI complaint images without installing any docker client or using Dockerfile for our SpringBoot application. We will be doing all of this with help of Jib.
Example with Django / Python and PostgreSQL.
So you have your Docker Containers deployed, which in turn are hosting critical applications of your organization? Great! So far, so good!
Docker is all the rage these days, with its simple and elegant way to package applications and even entire systems into something that can be ran on any Linux host with Docker installed. But what if Docker could be extended to desktop applications?
Introduction
By nature, pods in Kubernetes clusters are ephemeral. They can be created, killed, and moved around by the scheduler. This may occasionally cause disruption in the microservices if pods are not configured properly.
This is the introduction to a series that was originally published on tech.osteel.me. Only the introduction was brought to Hacker Noon — links to other parts will take you to that other website.
Sysdig is a universal system visibility tool with support for containers. What makes Sysdig special, is that it hooks itself into the machine's kernel and segregates the information on a per-container basis.
How to customize MariaDB Docker images: Execute SQL and shell scripts when the containers start and pass configuration files.
When it comes to certification, there are two main Kubernetes certifications available in the market.
Prometheus is an open-source application monitoring and alerting software solution. It is a web application which can be deployed anywhere — in a PC, virtual machine, or even in a container. It scrapes data from the exporters (small programs convert system data to Prometheus metrics) periodically and records the real-time metrics in a time series database.
Learn how to deploy a simple rest API with ExpressJS and expose it using a service and ingress. Great for Kubernetes personal projects.
In this article, I’ll try to explain the significance of OffChain Storage in Hyperledger Fabric and also the offchaindata application that I have built to demonstrate the offchain storage implementation using the Go Programming language for Hyperledger Fabric.
As your infrastructure grows, it becomes crucial to have robots and a reliable centralized logging system. Log centralization is becoming a key aspect of a variety of IT tasks and provides you with an overview of your entire system.
Docker is a container technology that enables developers to run entire applications as a unit. It offers all the benefits of virtual machines, without the high overhead:
Earlier this year at Spark + AI Summit, we had the pleasure of presenting our session on the best practices and pitfalls of running Apache Spark on Kubernetes (K8s).
Gremlin is a leading software company focusing on chaos-test in the market. It also has a tool similar to Chaos Monkey which belongs to Netflix, but is more customized to test the system with random loads or scheduled shutdowns. In the article below we will be testing a simple Kubernetes cluster running on EKS with Chaos Test.
Earlier, developers simply wrote their program, built it and ran it. Today, developers need to also think of the various ways of running it whether it be as a binary on a machine (virtual most likely), by packaging it into a container, by making that container a part of a bigger deployment (K8s) or by deploying it into a serverless environment or a service mesh. However, these deployment options are not part of the programming experience for a developer. The developer has to write code in a certain way to work well in a given execution environment, and removing this from the programming problem isn’t good.
Python is a versatile programming language that is popular and widely used for various applications, such as data science modeling and REST APIs. However, managing and maintaining a complex Python development environment can be challenging, especially when working on large or multi-faceted projects.
Podman is the command-line interface tool that lets you interact with Libpod, a library for running and managing OCI-based containers. It is important to note that Podman doesn't depend on a daemon, and it doesn't require root privileges.
