mysql:5.7 は ARM64 のコンテナイメージが提供されていないため、--platform linux/amd64 の指定が必須だった

指定しない場合

$ docker run --rm -it mysql:5.7
docker: no matching manifest for linux/arm64/v8 in the manifest list entries.
See 'docker run --help'.

指定した場合

$ docker run --rm -it --platform linux/amd64 mysql:5.7

しかし --platform linux/amd64 を指定して動くコンテナのバージョンは限られている。例えば Aurora MySQL と互換性のある 5.7.12 は --platform オプションを指定しても起動しない
