Let’s start today’s tech tip by identifying what a Kubernetes Context is. Kubernetes Context, which is also known as kubectl context, represents a Kubernetes cluster that kubectl command-line tool is currently targeting. You decide which Kubernetes cluster to set as active by modifying currently active context with kubectl config use-context <cluster_name> command. All the configured and available Kubernetes contexts are stored in a kubeconfig file. Kubeconfig file contains a collection of properties for every Kubernetes cluster that respective client is connected to - properties such as Kubernetes cluster name, authentication mechanisms, user/service account, etc. This information is used by kubectl command-line tool to connect to the API server of the respective cluster once it’s set as the active Kubernetes context. ...

In this blog post I would like to take a look at how we can ensure that Dockerfiles we create are of high quality and are following best practices in the industry. Tools like Hadolint make it very easy for us to do that and can automate the verification process. If you’re working with containerized applications or are planning on containerizing an application you will most likely be working with a Dockerfile. Dockerfile is a variation of a text file (without a file extension though) where you define a set of instructions for assembling, configuring and starting up your application container image. Those instructions are then compiled during the build process (for example, with docker build command) and are packaged into an artifact, known as a container image, which may then be pushed to a container registry like Docker Hub or Azure Container Registry. ...
