https://go.dok.community/slack https://dok.community/ ABSTRACT OF THE TALK Helm allows you to install packages in your cluster, much like you would use apt, yum on your laptop. Just define the components that you want to install in your application, and it will take care of the installation and configuration of these components, saving you from headaches. This talk will go through the package manager for Kubernetes and its components. In the end, we would deploy an application with Helm to our cluster with Portainer. BIO Hrittik is a Portainer Advocate, a software engineer at Ayedo GmbH and a student in his sophomore year.
