I’ve compiled as much info as possible in a gist here - but the recap is: it’s a totally “empty” mix phx.new . --app battery_rehab docker compose build works docker compose run --rm phoenix mix test works docker compose up ends phoenix with error 139 I’ve tried to google for it - but somehow I’v…

most likely something with arm64 and that image.. can you try using the hexpm/elixir image instead hexpm/elixir - Docker Image hexpm/elixir:1.12.0-erlang-24.1-alpine-3.14.0 maybe?

what computer are you on? looks like esbuild is getting arm64 linux, and then crashing - is that correct-ish?

I’m on an M1 (Apple) - and I won’t deny that it sat with me for nearly 8 months before I tried to do any good with it :biohazard: (mostly because things like brew turned out to be such a hazzle :slightly_frowning_face: )

but the container is running off of elixir:latest (the Dockerfile gives that away in line 1) but what “platform” has never been of much interest to me - I use it very frequently with Rails containers but I have to hurry to admit that I probably should care! And not knowing how to tell Docker to use…

thx! That had me going forward! Important lesson too! Not all platforms are made equal :wink: (not that I didn’t know that - from building on Symbian60 in the late '90’s - but I kind’a guessed that with Docker being an “abstraction layer” this sort of was a thing of the past) - guess not :smile: …

awesome! using https://asdf-vm.com for elixir/erlang/node and just running natively no containers is pretty big here in elixir land, so you can try that some adventurous day :wink:

I’m a big fan of asdf for sure - it did very well in ruby-land too, allowing me to context switch between 10+ year old projects and newly minted ones in a blink of an eye - or should I say cd :laughing: Maybe the communities around projects like nokogiri have it ironed out by now but going 10/12 mo…

Just wanted to say thanks for posting this thread. I hit the exact same error. I thought for sure it would be some obscure thing I’d have to Google for a while. But, nope, the question and answer were right there on the front page of Elixir Forum! :grin:

:mechanical_arm: to outlog - he’s the real hero in this terrible ordeal :smiley:

Docker is only a set of restrictions in terms of system calls, process visibility, filesystem access and networking. There is no hypervisor or virtual CPU.
