Instructions how to add the Epinio extension to the Rancher Dashboard

[thehejik]

Note: this is about Rancher Dashboard UI Extension not about Docker/Rancher desktop extension

We need $title, it should consist of following steps:

• Enabling the Rancher Extensions support
• Adding the rancher extension repository (when the extension is not shipped via official rancher channels)
• Installing Epinio over Rancher via official Rancher App chart repo - a graphical wizard using questions.yml file.
  Note: if E is installed via rancher the DEX and CORS are configured to accept also requests from rancher itself by using rancher internal variable global.cattle.url (populated automatically). If installing E out of rancher by helm CLI the needed value can set via --set rancher.url=https://<my-rancher-url flag.
• Installing the Epinio extension from the extension repo
• Usage of the Epinio extension within Rancher - where to find the E dashboard in Rancher, how to do auth (local+dex supported for now). The basic usage is identical with standalone Epinio UI, there will be just an extra rancher side bar present in addition.

Update: The idea is to follow existing Kubewarden documentation where the extension part is covered.

We have some developer docs over at https://github.com/epinio/ui/tree/main/docs/developer#production-flow. Note

• there's some restrictions on versions of rancher and epinio
• the extension repo will change once Add Epinio extension to rancher/ui-plugin-charts ui#284 has been resolved, i think we just change it at that point though
• with Improve landing experience when using ui extension ui#367 users will be able to install the ui extension, go to the epinio page and select a cluster to install epinio on (which takes them to the cluster's helm install wizard)
