Docker Build 文件权限错误并返回非零代码：126

Question

我在创建 docker 映像时收到“返回非零代码：126”的错误消息。 这是 docker 文件：

FROM centos/s2i-core-centos7


ENV MYSQL_VERSION=5.6 \
    APP_DATA=/opt/app-root/src \
    HOME=/var/lib/mysql

ENV SUMMARY="MySQL 5.6 SQL database server" \
    DESCRIPTION="MySQL is a multi-user, multi-threaded SQL database server. The container \
image provides a containerized packaging of the MySQL mysqld daemon and client application. \
The mysqld server daemon accepts connections from clients and provides access to content from \
MySQL databases on behalf of the clients."

USER 27

ENTRYPOINT ["container-entrypoint"]
CMD ["run-mysqld"]

运行此程序时，在最后阶段出现错误。 我无法找出问题所在。 或者，如果有人有更好的 MySQL 5.6 或 5.7 docker 文件，以 centos7 作为基本映像，请给我。

在这种情况下，有人可以帮助我吗？
