We are trying to make a new Plone 6.0.0a4 env in our local env by docker. We can make a vanilla Plone 6.0.0a4 with volto by docker. But we could not install volto add-ons like the demo site (https://6.demo.plone.org/).
We want to install 3 add-ons,
- @eeacms/volto-object-widget 3.0.3
- volto-slate 5.3.3
- @kitconcept/volto-blocks-grid 2.4.1
Please let me know how to set up the add-ons by docker.
