Reading Time: 3 minutes Crossplane has been gaining popularity in recent times. Crossplane works well with Kubernetes in the frame. We can now manage the deployment of microservices in the k8s cluster and also the managed components of the cloud (cloud services) using a single tool. Moreover, you can configure the same deployment tool (like, Argocd) for the same. Pre-requisites AWS credentials You will have to get the base64 Continue Reading
Reading Time: 4 minutes In this blog we will learn about secrets management in Kubernetes. This will be a descriptive blog and it will be followed by a practical implementation of sealed secrets in the upcoming blog. We will know how sealed secrets will help us follow the Gitops approach where secret manifests can be safely stored in a GitHub repository post encryption. What is Kubernetes? Kubernetes is an Continue Reading
Reading Time: 3 minutes This is a practical implementation of the previous blog: Introduction to Sealed Secrets in Kubernetes.In this blog, we will create secrets in Kubernetes with the help of sealed secrets. Pre-requisites: Install kubeseal Kubeseal is a CLI tool that seals a secret with the help of the controller’s public key and creates a CRD for the sealed secret. wget https://github.com/bitnami-labs/sealed-secrets/releases/download/v0.19.2/kubeseal-0.19.2-linux-amd64.tar.gz tar -xvzf kubeseal-0.19.2-linux-amd64.tar.gz install -m 755 Continue Reading
Reading Time: 2 minutes What is Kubernetes ? Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications. What is a Pod in kubernetes ? Pods are the smallest, most basic deployable objects in Kubernetes. A Pod represents a single instance of a running process in your cluster. Pods contain one or more containers, such as Docker containers. When a Pod runs Continue Reading
Reading Time: 3 minutes Hello Readers!! In this blog, we are going to see a new tool i.e Kail. We will see how we can use kail to view logs in Kubernetes. Frequently we use the kubectl command for looking at the logs of pods in Kubernetes. But it is not resilient to use when we want to see the logs from multiple pods. So, here is a very Continue Reading
Reading Time: 5 minutes Introduction This blog is similar to previous blog where we explored service mesh configuration using User Interface. Here, we will see how istio is able to manage certification for cluster. Since it was a long topic we will cover the external certification addition part in Part 2. Terms to be known Istiod works as both RA and CA. Istio manages certificates by istiod itself. Installation Continue Reading
Reading Time: 4 minutes Introduction In our old blog, we explored service mesh configuration using User Interface. Here, we will see how istio is able to manage certification for cluster. This blog covers left work of Part -1 where we explored on how istio itself creates certificates for cluster and manage certificates for cluster. We will see various ways the istio can add external certifications. Terms to be known Continue Reading
Reading Time: 6 minutes Hello Readers! In this blog we are going to see all about kontena lens-Beautiful kubernetes UI. Here we will see how to use the kontena lena user interface to manage multiple kubernetes clusters at the same time. This does not only provide a beautiful and interactive UI but also we can use it for accessing and managing configurations of your cluster. So, let’s get start Continue Reading
Reading Time: 3 minutes Hello Readers! In this blog we are going to see all about web kubectl. What it is and What’s the use case of web kubectl. So, As its name suggests it is use for running the kubectl command in a web browser. With the help of this you can also manage your kubernetes credentials. One of the main benefits is that the user doesn’t need Continue Reading
Reading Time: 3 minutes In this blog we will quickly go through the steps to deploy Keptn with the help of replication controllers in Kubernetes !! So lets dive in 🙂 What is Keptn? Keptn is an open source control plane to build cloud-native, industry-driven continous delivery systems. According to Dynatrace, Keptn augments any standard Kubernetes cluster to support delivery based on automated quality gates and self-healing operations workflows. Continue Reading
Reading Time: 2 minutes In this era of microservice based architecture where multiple services are interacting with each other to carry out a transaction, service discovery becomes an integral part as it provides a mechanism to register and find the services. However, it leads to another issue which is “How to select the right service instance in case we have multiple instances of a service running?” . SmallRye Stork Continue Reading
Reading Time: 5 minutes Why Sealed Secrets? As we know, Secrets in Kubernetes are used to store sensitive data, like password, keys, certificates and token. Secrets are encoded in base64 and automatically decoded when they are attached and read by a Pod. A secret in Kubernetes cluster is encoded in base64 but not encrypted! These data are “only” encoded so if a user has access to your secrets, he can simply execute Continue Reading
Reading Time: 4 minutes In this blog, we will learn about Ingress and how to create ingress rules, So Stay Tuned! PREREQUISITES Minikube Cluster kubectl Installed WHAT IS INGRESS? Ingress is an API object that allows the external traffic to the Kubernetes cluster based on the routing mechanism. It provides routing rules to manage external users’ access in a Kubernetes cluster via HTTP/HTTPS. WHY DO WE USE INGRESS? An Continue Reading
