Memory limits

Q: Pod failing with 'Invalid value: "xxx": must be less or equal to memory limit' error.

This error may be encountered when you specify a value in the Head Job memory field during the creation of a Kubernetes-type compute environment.

If you receive an error that includes field: spec.containers[x].resources.requests and message: Invalid value: "xxx": must be less than or equal to memory limit, your Kubernetes cluster may be configured with system resource limits which deny the Nextflow head job's resource request. To isolate which component is causing the problem, try to launch a Pod directly on your cluster via your Kubernetes administration solution. Example:

---
apiVersion: v1
kind: Pod
metadata:
  name: debug
  labels:
    app: debug
spec:
  containers:
    - name: debug
      image: busybox
      command: ['sh','-c','sleep 10']
      resources:
        requests:
          memory: "xxxMi"    # or "xxxGi"
  restartPolicy: Never
