      = Some sample devfiles require more CPU or RAM than is available to RHPDS clusters

      Currently, the available CPU or RAM resources on a RHPDS cluster may not be sufficient for a devfile.

      .Workaround

      * In the *Administrator* perspective of the OpenShift Container Platform web console, choose the correct project, go to *Administration* > *LimitRanges*, and delete the *LimitRange* object for the CRW deployment.

      * Alternatively, the RHPDS administrator can grant users more resources by providing a customized instance with higher limits for CPU or RAM.

      1. Create cluster on RHPDS.
      2. Deploy CRW 2.14.0 (GA version using che server; NOT 2.14.100 tech preview with devworkspace support)
      3. Start workspace from any Java deviles(for example Java with JBoss EAP XP 3.0 Microprofile).

      Cannot start workspace from java devfiles in CRW 2.14.0 on RHPDS cluster. Maven pod cannot starts because of limits error -> "Error creating: pods "workspaced4k21j9tmb454val.maven-7c57f58bf4-n9jz5" is forbidden: maximum cpu usage per Pod is 4, but limit is 4300m". 

      When admin-codeready project is created it has next limits in LimitRanges:

      spec:
  limits:
    - type: Container
      max:
        cpu: '4'
        memory: 6Gi
      default:
        cpu: 500m
        memory: 1536Mi
      defaultRequest:
        cpu: 50m
        memory: 256Mi
    - type: Pod
      max:
        cpu: '4'
        memory: 12Gi

       
      It has max cpu 4 but maven pod wants 4300m. After increase cpu property workspace starts sucessfully.

      This issue doesn't reproduce with CRW 2.13.0 on RHPDS.
