I had trouble running this on an arm dokploy instance. The images are x86

Thanks for putting this together, Juan! Great to have the Dokploy blueprint scaffolding in place.

A few things I noticed:

Missing files referenced in the README
The README lists arche/docker-compose.yml and arche/instructions.md as included, but they're not in the PR. Without at least the compose file the template can't be imported into Dokploy. Could you either add them here or scope the README to what's currently present?

KB_HOST_PATH undocumented
template.toml defines KB_HOST_PATH = "" and passes it through, but the README doesn't mention it. Should it be removed or documented?

[[config.domains]] uses ${domain} vs ${ARCHE_DOMAIN}
Just want to confirm ${domain} is the correct Dokploy built-in here and not a typo for ${ARCHE_DOMAIN}.

Hey Arche team, thanks for the feedback. I can work on your suggestions.

Would it be possible to publish an arm64 image as well? Getting this error on an ARM EC2 running Dokploy — building locally works as a workaround but it's not ideal.

Hi @juandelperal - The arch issue is being addressed in #270 so soon there should be arm64 image too, for both the workspace and the web app.

Hi Alberto and team!

In arm this keeps happening:

is this the right tag or should i set something different here?
WEB_IMAGE = "ghcr.io/peaberry-studio/arche/web:latest"

Thanks
