Large memory needs to run CRC container images in basic developer experience

[eschabell]

General information

• OS: macOS
• Hypervisor: hyperkit
• Did you run crc setup before starting it (Yes)?

CRC version

# Put the output of `crc version`

crc version: 1.11.0+883ca49
OpenShift version: 4.4.5 (embedded in binary)

CRC status

# Put the output of `crc status`

CRC VM:          Running
OpenShift:       Running (v4.4.5)
Disk Usage:      16.48GB of 32.72GB (Inside the CRC VM)
Cache Usage:     12.12GB
Cache Directory: /Users/eschabel/.crc/cache

CRC config

# Put the output of `crc config view`

- cpus                                  : 4
- memory                                : 12288
- pull-secret-file                      : /Users/eschabel/bin/pull-secret.txt

Host Operating System

# put the output of `sw_vers` in case of Mac
ProductName:    Mac OS X
ProductVersion: 10.15.4
BuildVersion:   19E287

Steps to reproduce

1. install crc with above config
2. install RHDM 7.5 authoring image from container catalog (see https://gitlab.com/redhatdemocentral/rhcs-retail-webshop-demo/-/blob/master/init.sh for steps used)
3. install EAP 7.5 basic s2i image from container catalog (see https://gitlab.com/redhatdemocentral/rhcs-retail-webshop-demo/-/blob/master/init.sh for steps used)
4. watch them spin up the pods and depending on order, one of the three pods will fail with "0/1 nodes are available: 1 Insufficient memory."

Expected

That all pods spin up and deploy.... why does this developer experience CRC based on OCP 4.4 need 12 GB and the basic product images can't be used for a web front-end app on EAP and RHDM decision service backend?

This project was used succesfully on OCP 3.x with 3-6GB of memory.

Actual

Something should be done to provide a developer experience on their local machine that can run with a lot less memory.

Logs

Out of memory errors kills attempts to get you logs. See attached screenshots.
