Fala amigo... tenta resolver isso parando o docker-compose e mudando as permissões do diretório do mysql, tive um problema semelhante.

resolvi com chmod +777 no diretório do mysql, ou seja, dando permissão total. Como é ambiente de lab não tem problema, pode ser uma solução para prosseguir tranquilo.

espero ter ajudado
