Before you begin, make sure you have the following tools installed and set up on your local environment:
Skaffold is used to build, push, and deploy your application to Kubernetes.
You can install it by following the instructions here.
Helm is a package manager for Kubernetes, enabling you to manage Kubernetes applications easily.
You can install it by following the steps here.
Minikube runs a local Kubernetes cluster, ideal for development and testing.
You can install it by following the guide here.
Start your minikube instance with:
minikube start
Kubectl is a command-line tool for interacting with Kubernetes clusters. It allows you to manage and inspect cluster resources. While not strictly required, it's highly recommended for debugging and interacting with your Kubernetes environment.
You can install it by following the instructions here.
OpenLens is a graphical user interface for managing and monitoring Kubernetes clusters. It provides a visual way to interact with resources.
While it's optional, it can significantly improve your workflow. You can download it here.
helm repo add localstack https://helm.localstack.cloud
helm repo add zoo-project https://zoo-project.github.io/charts/
After installing these tools, ensure they are available in your terminal by running the following commands:
skaffold version
helm version
minikube versionIf all commands return a version, you’re good to go!
Run the Mastering Earth Observation Application Packaging with CWL module on minikube with:
cd mastering-app-package
skaffold dev
Wait for the deployment to stablize (1-2 minutes) and the open your browser on the link printed, usually http://127.0.0.1:8000.
The typical output is:
