A Kubernetes Secret is an object that enables us to store and manage sensitive information. A Secret can contain data like SSH keys, OAuth data, or other user authentication information like passwords. It is typically stored within a cluster in a manner native to Kubernetes. Using a Secret object provides more granular control over how highly sensitive data is used. It also lowers the risk of data exposure to unauthorized parties.

KubeKey is the newest Kubernetes installer for KubeSphere. KubeSphere is a distributed OS management system for cloud-native applications using Kubernetes as its kernel. It provides a plug-and-play structure for seamless integration of many third-party applications. It is somewhat similar in nature to MiniKube for installing Kubernetes.

KubeKey was developed using the Go programming language. It provides a quick method to install Kubernetes and any additional add-ons using Chart or YAML files. KubeKey uses the kubeadm application to install a Kubernetes cluster on multiple nodes in a synchronous manner to reduce the complexity of the installation and improve efficiency. Using KubeKey reduces installation time considerably compared to many other installation techniques.

Using Telepresence to Improve Microservice Development

Reading Time: 4 minutes

What is Telepresence?

Initially developed by Datawire, Telepresence is a new open-source tool supported by the CNCF (Cloud Native Computing Foundation). It allows developers to run local software while connected to a remote Kubernetes cluster. The application uses a two-way network proxy to simulate TCP connections, environmental variables, and other volumes of services as local processes. This link allows for remote work to be accomplished while seemingly local to the cluster via the proxied connection.
