Best local EX280 / DO280 practice environment on M1 MacBook?
Hi everyone,
I’m currently studying Kubernetes locally on my 16GB M1 MacBook using UTM with 3 Linux VMs.
The setup works reasonably well for Kubernetes practice, but now I want to start preparing for the Red Hat EX280 / DO280 exam and I’m not sure what kind of OpenShift environment would work best on Apple Silicon Macs with limited memory.
I’m actually just a backend developer, not an infrastructure engineer. In my current job I use Ansible quite often, but I’ve become very interested in OpenShift recently and honestly just want to learn it deeply because I feel like it could become useful for me someday.
I tried searching for good Apple Silicon/M1 learning setups for OpenShift, but I couldn’t really find clear answers or realistic home-lab examples, so I decided to ask here directly.
Since I’m studying personally, I cannot afford Red Hat’s paid training or subscription services.
I’d like to ask:
- What environment are you using for EX280 practice on Apple Silicon Macs?
- Is OpenShift Local (CRC) usable on a 16GB M1 Mac nowadays?
- Would you recommend continuing with UTM VMs + OpenShift Local?
- Are there any good free/community alternatives for practicing OpenShift administration?
- Which setup feels closest to the actual EX280 exam environment?
Right now my goal is mostly:
- oc CLI practice
- troubleshooting
- deployments/routes/storage/configmaps/secrets
- general OpenShift admin tasks
Any advice or study setup recommendations would be greatly appreciated.
Thanks!
