Helm is the package manager for Kubernetes that simplifies deploying and managing applications on a Kubernetes cluster. It streamlines the process with pre-configured packages (charts) and simplifies updates, rollbacks, and collaboration in a Kubernetes environment.
How to install Helm
Install Helm using apt.
Check that Helm has been installed and can access the Kubernetes cluster.
If using K3s, set the configuration for Helm

curl https://baltocdn.com/helm/signing.asc | gpg --dearmor | sudo tee /usr/share/keyrings/helm.gpg > /dev/null sudo apt-get install apt-transport-https --yes echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/helm.gpg] https://baltocdn.com/helm/stable/debian/ all main" | sudo tee /etc/apt/sources.list.d/helm-stable-debian.list sudo apt-get update sudo apt-get install helm
