standard_init_linux.go:211: exec user process caused "exec format error"
I'm not sure if it's a copy/paste error, but you will either want to specify a version (apt-get install -y stardog=7.0.0) or not (apt-get install -y stardog).
I think the error you're seeing is because you're trying to run a amd64 image on arm hardware. You might be better off trying to get Stardog running without docker first then if you're successful try building a docker image for arm64.
I've been successful getting Stardog 6.x to run on a raspberry but haven't had a chance to run the new 7.x yet and I'm not sure how the new RocksDB dependency changes things. I'll have to give it a try tonight.
I keep forgetting...arm. You can try installing from the .zip but as I mentioned I don't think it will run because of the dependency on rocksdb. I believe rocksdb supports arm but that would probably require an arm specific Stardog build.....wink-wink, nudge-nudge
