I love seeing movement in the nostr #devops space through Sebastix (npub1qe3…zefe) with arjenstens (npub1hw6…65gr) and elsat (npub1zaf…26k5) getting started with decentralised devops. I recently blogged about github actions to build multi-arch docker files to build ARM compatible relay software, might come in handy! Let me know if I can help you out!
