elkarbackup不会连接到mysql

Question

我正在尝试使Elkarbackup的容器连接到mysql容器，但是所有日志都显示为："MySQL is unavailable - sleeping,"

两个容器都在同一网络上（默认）。 还有其他人遇到类似的问题吗？

似乎我现在已经尝试了几乎所有东西。阅读docs / man-pages，它“应该”工作...

服务器：Ubuntu 18.04 Docker版本18.09.0，内部版本4d60db4 docker-compose版本1.23.2，内部版本1110ad01

这是我的docker-compose.yml文件：
