手动缩放停靠gitlab运行程序的实例

我和docker在gitlab跑步时遇到问题。 当我用1个实例运行下面的容器时，一切都很顺利。预期的跑步者人数显示为在管理面板中注册的人数。当我扩展服务时，一些已拾取的作业将失败，并出现以下错误：

Running with gitlab-runner 12.7.1 (003fe500)
  on Docker Runner 638bede4
Using Docker executor with image docker:latest ...
Pulling docker image docker:latest ...
Using docker image sha256:31c774f62a9b520060d72c3c1901facdfdfd0fc4ae7c5e817cdaf6acd456432c for docker:latest ...

ERROR: Job failed (system failure): Error: No such container: 2f39fdd536cd4278ecc740479e3976da25f871ab71febc624f7030d59000b029 (executor_docker.go:788:0s)

根据这位官员的说法，这是意料之中的，因为我共享同一个config.toml。但是，当我将卷挂载移到保存config.toml的目录时，运行程序根本不会选择作业

我的问题是：如何在docker设置中缩放跑步者而不共享相同的config.toml

更新：升级gitlab版本后，问题有所缓解。但是，在官方文档中，关于不为跑步者共享configuration.toml的警告仍然存在。所以我最初的问题仍然存在
