[shirady]

Environment info

• NooBaa Operator Version: Current master (5.15.0)
• Platform: Kubernetes v1.23.12 | minikube v1.30.1 | Rancher Desktop 1.11.0

Actual behavior

1. Creating pv-pool backingstore in Rejected phase.

Expected behavior

1. Creating pv-pool backingstore in Ready phase.

Steps to reproduce

1. Install noobaa with --dev flag: nooba install --dev --noobaa-image <image-of-current-repo> -n <namespace-name>.
2. Create backingstore with type pv-pool (using the creatiom example here): nooba backingstore create pv-pool <pv-name> -n <namespace-name> --num-volumes 3 --pv-size-gb 17.

I found that:

noobaa-operator/pkg/backingstore/backingstore.go

Line 254 in 5d7b041

minCPUStringByEnv, minMemoryStringByEnv := getMinimalResourcesByEnv()

In this line (and the function inside of it) it tries to find the DEV_ENV in the CLI process which doesn't exist (we use this environment variable in the operator's deployment) - unless we would set it manually (export DEV_ENV=true in the terminal where the CLI runs).
