Mail-receiver lacks an official ARM-compatible image

[Canapin (Coin-coin le Canapin)]

Continuing the discussion from Does the mail-receiver work with arm?:

It has been mentioned a couple of times on meta, but I guess it’s better if it has its own Feature request topic.

Discourse works great on ARM servers. I never came across any issue.
Unfortunately, running it on this architecture prevents you from using the official mail-receiver image.

From a technical perspective, I know absolutely nothing and I (confidently) rely on what Matt said in the linked topic:

@mpalmer

It would certainly be possible to support mail-receiver on ARM systems. There’s nothing amd64-specific in there (or, at least, there wasn’t when I made it, and I can’t imagine any major changes would have been made to invalidate that assumption).

@mpalmer

If anyone’s interested, I’ve done an arm64 image build and pushed it to womble/discourse-mail-receiver:arm64, to tide people over until such time as the core team can get an official image build spun up. See my branch’s README for more details on limitations (no socketee for now; I’ll add it if anyone says they need it), how to use it, and how to report problems (ie “tell me, not the core team”).

Added my vote here. I think it would be really nice if the complete Discourse stack worked with ARM64.

I’d also be happy to PR the changes to align mail-receiver with the ARM64 build process used by discourse_docker/.github/workflows/push-web-only.yml at main · discourse/discourse_docker · GitHub
