Eclipse CHE Workspace Memory Limits

[gss2002]

Summary

It seems as if Eclipse Che Workspaces are limited to 1152Mib of memory. I attempted to set: " CHE_WORKSPACE_DEFAULTMEMORYLIMIT__MB: "4096" it seems to be ignored. The only way that seemed to get the mem increased was to edit each individual workspace and adjust the memoryLimit setting. Does anyone have any insight if this actually works. Also setting memoryLimit in a devfile.yaml also seems to be ignored.

Works but only with individual workspaces:

    - container:
        image: quay.io/devfile/universal-developer-image:ubi8-latest
        memoryLimit: 4Gi
        sourceMapping: /projects

  conditions:
  - lastTransitionTime: "2024-03-22T19:55:06Z"
    message: Workspace is stopped
    status: "False"
    type: Started

Once the POD starts running its always "1152" no matter what is set unless you edit the workspace template:

The field below has no effect, since it was introduced for che-server devworkspace engine (prior 7.42.0)

spec:
  components:
    cheServer:
      debug: false
      extraProperties:
        CHE_WORKSPACE_DEFAULT__MEMORY__LIMIT__MB: "4096"`

Use [1] to configure resource limits for workspaces.
