portainer_scripts/comparison script

Hello, Adolfo from Portainer here

We have prepared a set of comparison videos of Portainer vs 4 different Kubernetes management tools:

Kubernetes Dashboard
Lens
CrossPlane
Rancher UI


the idea is to basically show the steps required to deploy an application on each of the tools vs Portainer and I am going to use a basic implementation of the redis database.



Here I start with Portainer vs Kubernetes Dashboard with a redis server deployment. In both cases I use microk8s and the process starts with the search for the proper container image in both cases.

In Portainer I used the Applications menu option and deployed redis with ,


bitnami/redis
