Docker image fails to build on Apple Silicon (M1-ARM64 architecture)

[wonderbird]

When you run

docker build -t code-maat-app .

on a Mac with Apple Silicon chip, then docker fails with the following error message

ERROR [internal] load metadata for docker.io/library/clojure:alpine
...
error: failed to solve: failed to solve with frontend dockerfile.v0: failed to create LLB definition: no match for platform in manifest sha256:d7bcb938ec3e6cef737e621e83f82b6ebbf6e60ebf5e4354c2f7d5418bb7cc5c: not found

I suspect that the base image clojure:alpine is not available for the linux/arm64 architecture at the time of writing.

I wouldn't change anything in code maat for now. Instead, let's use this thread to make users aware of the issue and present workarounds for the time being.

As a very slow workaround, one could run

docker buildx build --platform linux/amd64 -t code-maat-app .

This would use the Rosetta 2 emulation.

On my machine the build process took extremely long (I aborted after about 12 minutes).

I prefer the following workaround, which trades off container size against time behaviour:

1. Change the FROM line in Dockerfile such, that the latest clojure image is used instead of the alpine version:

   FROM clojure:latest
   

2. Build and use the docker container as usual

   docker build -t code-maat-app .
   docker run -v "$PWD":/data -it code-maat-app -l /data/hib_evo.log -c git -a authors

I had exactly the same problem, and also reached the same workaround as you @wonderbird

Perhaps a fix for this will be to just make a note in the README to update from FROM clojure:alpine to FROM clojure:latest for apple silicon devices?

I just used the clojure:latest workaround as well, still working fine in 2023 (and the original issue with the alpine image is still present upstream)
