要求在不同的终端中运行三个 docker 命令：

  • 零
  • α
  • 率

我宁愿从 Mac OSX 10.3.6 和其他环境中的单个脚本 dgraph 开始，并使用例如终端应用程序按照在新的 Mac OS X 终端窗口中运行命令的行调用不同的脚本

下面的脚本如何适应 Unix 和 Windows 等其他环境？

https://github.com/WolfgangFahl/DgraphAndWeaviateTest/blob/master/scripts/dgraph现在有一个在 Linux 上工作的脚本（用 travis/Ubuntu 18.04 LTS - 仿生测试）。

另见https://travis-ci.org/github/WolfgangFahl/DgraphAndWeaviateTest/jobs/715131236

用法

scripts/dgraph -h
scripts/dgraph [-b|--bash|-h|--help|-k|--kill|-p|--pull]

-b | --bash: start a bash terminal shell within the currently running container
-h | --help: show this usage
-k | --kill: stop the docker image
-p | --pull: pull the docker image
