Comment 2 for bug 1981116

I know it's been far too long before looking at this -- i apologize sincerely for that.

I wanted to try to address this issue and saw that your bundle deployment ran into an issue deploying `easyrsa` from a ras-pi juju client which of course is arm64. I frequently test against arm64 instances on AWS and don't run into trouble with the deployment -- but I feel like there's a constraint somewhere in the bundle you've deployed which is defaulting the easyrsa unit to have an arch=amd64

I'm making this assessment based on `invalid constraint value: arch=amd64`

I've looked at the current stable charmed-kubernetes bundle and the only constraints on workers is:

`constraints: cores=2 mem=8G root-disk=16G`

the architecture of the juju client (ie -- the terminal you launch the juju deploy from) shouldn't necessarily influence the architecture of the target cloud. I think what's happening is that juju doesn't know it needs to constrain the architecture of your cloud to arm64 machines (if that's what is intended) [1]

When I need to deploy charmed-kubernetes to arm64 only, here's the overlay I deploy with -- effectively forcing juju's hand on deploying the a different architecture rather than letting it have to pick based on the type of cloud you're asking juju to deploy to.
