Delays in app delivery to #kubernetes

Delays in App Delivery to KubernetesDelivering enterprise applications to KubernetesEnterprises around the world are waking up to the #containers and Kubernetes trend. 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.Major roadblocks while achieving continuous deliveryTo modernize, breaking down large applications into smaller microservices is just a start. The main challenge is in continuously delivering these microservices as (...)

SSH key management is a rabbit hole in itself and most people understand the #security concerns that arise with improper SSH key hygiene. Luckily for us, there is a way to bid farewell to the the cumbersome practice of using SSH to remote into an EC2 instance.

Photo by chuttersnap on UnsplashThere has been a conscious move within SaaS companies towards microservice architectures. To facilitate that, we generally use #docker setups. Well, let us not skip steps and see why people recommend this.To better understand #containerization and Docker, let’ use the example of the actual thing it is modeled after, Shipping Containers.Why use Shipping Containers?Well, shipping containers revolutionized the transportation industry by standardizing and making it simple to transport large quantities of goods. This could be over sea or land. Now with these standard containers, we are able to ship multiple things in one container or even ship large quantities of a single thing in multiple containers. Some of the key features here are:Standardized: These shipping (...)

Cloud cost hacking
▻https://hackernoon.com/cloud-cost-hacking-fc35fd19985d?source=rss----3a8144eabfe3---4
One of the primary motivations for using the cloud are flexibility and cost saving. The problem is that without ongoing management and oversight, the cloud budget can grow to dimensions that eliminate profitability.A recent study on the cost of using the cloud has shown that companies pay an average of 35% more on cloud services than they really should. A total of over $60 billion is being wasted on cloud services that are not in use.In this article, I will share my conclusions from recent cloud cost optimization processes and review a number of ways and tools to significantly reduce cloud costs 30–50%, without sacrificing performance. The recommendations in this article are valid for all cloud vendors unless otherwise specified.Tools for managing cloud costsBefore you start saving it is (...)

Docker Swarm, Kubernetes’s clever little brotherIs kubernetes suitable for any container based project?There is no doubt that kubernetes is one of the most talked about technologies in the domain of #cloud and #containers. Kubernetes provides a complete solution to managing containers, but there are cases where it is not the best solution.The main disadvantage of kubernetes is its complexity and learning curve. This complexity is due to several reasons:We need to know both the “language” of Docker and the “language” of kubernetes.There are a lot of “moving parts” in the infrastructure (kube-apiserver, etcd, kube-scheduler, kube-controller, kubelet, kube-proxy etc..)There are many types of objects (Service, Pod, Deployment, ReplicaSet)A vast amount of features that we do not necessarily need.In (...)

If you work in development or IT Ops, you probably spend much of your day staring at dashboards — a reality that makes IT work much less glamorous than it might sound. We use dashboards to manage code repositories, track builds, coordinate deployments, monitor software in production, and much more.Indeed, you probably have dashboards that aggregate data from other dashboards, because otherwise there would be so many dashboards that you would not be able to keep track of them all.If you’re tired of drowning in dashboards, there’s hope. With the help of GitOps, a new approach to managing software delivery, we can remove many of these dashboards from our lives and replace them with a streamlined, centralized management interface based on configuration files and pull requests.Here’s what the (...)

What Is #containerization ?

In traditional software development, code developed in one computing environment often runs with bugs and errors when deployed in another environment.Software developers solve this problem by running software in ‘containers’ in the cloud.How #containers WorkContainerization involves bundling an application together with all of its related configuration files, libraries and dependencies required for it to run in an efficient and bug-free way across different computing environments.The most popular containerization ecosystems are Docker and Kubernetes.Apps and their dependencies sit in containers on top of a ‘container runtime environment’ which can work on a host operating system and the infrastructure of choice.Containers versus Virtual MachinesContainers are often compared to Virtual (...)

How I Installed an OpenShift Cluster on DigitalOceanWhen I wanted to window shop OpenShift, I had 2 options, either set up on my local using Minishift(previously using an all-in-one VM) or using the “oc cluster up” method. While they are good options, you don’t get the real feel of trying out OpenShift without deploying it on a real cloud-ish setup.Why DigitalOcean?I had a few hiccups with cloud-based setups, they were too big for my needs and came in with components I didn’t really need, and sometimes way over budget. If you check the hardware requirements for running OpenShift, you’ll know what I’m talking.My aim was to set up a production-ish cluster, not too brittle, at the same time not big enough to power the backend of a bank. I went with a VPS provider like DigitalOcean, so that I (...)

While some of these software tools you can obtain from package managers (e.g. Aptitude, Snap, Homebrew, etc…), they can still have quite complex installation steps (which could randomly change and break!).These steps might be documented, they might not.

How to Move Code into a #docker Container
▻https://hackernoon.com/how-to-move-code-into-a-docker-container-ab28edcc2901?source=rss----3a81
Docker provides two good options for moving your code into an image or container: bind mounts and the Dockerfile COPY instruction. In this post, I’ll explain why images should always use the COPY instruction in production, and why it may be more convenient to use bind mounts in development.Dockerfile COPY InstructionThe COPY instruction in a Dockerfile is used to copy files or directories from the host machine filesystem into an image. For example, the following Dockerfile sets up a NodeJS application for running in production mode.# DockerfileFROM node:carbonWORKDIR /appENV NODE_ENV=production# Install dependencies first to take advantage of Docker layer caching.
