LFS258 Labs are not portable ....

aristideboisseau

Hi there,

It would be nice to use compatible/supported containers images for both amd64 and arm64 architectures. Which is not really the case.

For instance, I'm not able to work/test the review2.yaml from the LAB_A.3.pdf
as the goproxy is for and only for linux/amd64.

My infra is based on a Mac M4 running Multipass and ubuntu instances for the k8s cluster...

Same for the next review3.yaml which use vish/stress only for amd64 ....

I might discover other incompatibilities for my platform in the next review files :-(

Kind regards,
Aristide

Hi @aristideboisseau,

Your concerns will be conveyed to our course maintainer.

In the meantime, on your M4 ARM powered Mac you can provision AMD compatible guests with hypervisors like Parallels, VMware Fusion, QEMU, or UTM.

It is not possible to install amd64 iso even using WMware fusion. The hardware requirements should be explicited. After spending the money I cannot finish the labs, not a great view in my opinion

Hi @storralba,

What about an ARM iso? Perhaps Ubuntu Server 24.04 LTS for ARM as a guest OS in a VM to get yourself started?

Hi Chris,
Thanks for the answer, the problem is not in installing a guest OS, the image for Ubuntu Server 24.04 LTS arm64 works fine for the installation, but some of the Helm files try to use images that are not compatible with ARM64 and then some steps of the labs just fail. As the images for the exercise (so far) does not matter may be should be better to use ones that their compatibility is bigger
