@ivucica, here is what I’ve come to understand.

The former quickstart which previously relied on docker no longer works. The old docker commands will spin up the containers with the Che 7 images, but nothing will work, and you’ll experience the behavior you are seeing.

Per the Che 7 Quickstart, Che 7 requires either

• a K8s environment, such as through minikube, or
• an OpenShift environment, such as through minishift.

You must also install chectl (instructions in the quickstart), and manage Che 7 through that. Do not use the previous docker commands that allowed you to manage Che 6.

Regarding your old configurations: Workspaces no longer have installers, and instead use Plugins and Editors. If you want to use the new format, you need to remove the JSON attribute “Installers” from the workspace “config” tab. The functionality previously done through installers is now loaded as a sidecar container. This is actually pretty slick.

Not sure about your keycloak, if you can keep it or not. Good luck!

Hi @eivantsov I’m facing the same problem running Che 7.0.0-RC-1.0. I’m not able to start any Che7 (with Theia) workspaces provided ooo on the section “new Workspace”, they fails with the same error or a generic message “Workspace Stopped”. Could you clarify better what’s the reasons is and how to fix it?
