Alpine Sprint Plone helm effort

xiru commented 7 months ago

All previous code from charts/plone is moded to plone6-volto-zeo without major changes.

Main changes are the following:

renamed "plone" helm chart to "plone6-volto-zeo" (probably needs a refactory to become closer to other implementations)
added new charts for plone using relstorage with postgresql, decouple frontend and backends, nginx and varnish
change backends to StatefulSets, so we are able to use varnish directors and do proper load balancing (with backend failure graceful support)
removed useless serviceaccounts (plone does not talk with k8s api, so we don't need that)
turn ingress configs off by default. as a safety measure, ingress configs should be configured explicitly.
add support for arbitrary injection of environmnet variables, enabling the usage of standard plone default env vars (e.g. turn on debug mode)
add support for PodDisptionBugets on all objects with more than one replica.

Now this PR is read for code review :)

Can the diagrams be exported as SVG instead of PNG? I would love to be able to read the text.

yes, that's possible. I will do that change.

I am going to merge this if there are no further complaints within the next 24h.

@jensens please wait for me to review docs again. I don't want to lose all the suggestions in this PR and start all over. I've been super busy or sick at the Axolote Sprint.

@stevepiercy ... super busy or sick at the Axolote Sprint.

Together this does not sound like a healthy combination. Get well soon!
