我为面试安装了 dgraph gru

go get github.com/dgraph-io/gru
cd $GOPATH/src/github.com/dgraph-io/gru
git checkout develop
go build . && ./gru -user=admin -pass=pass -secret=0a45e5eGseF41o0719PJ39KljMK4F4v2
docker run -it -p 127.0.0.1:8088:8080 -p 127.0.0.1:9080:9080 -v ~/dgraph:/dgraph --name dgraph dgraph/dgraph:v0.7.5 dgraph --bindall=true

当我尝试创建测验或问题时出现以下错误

我尝试了不同版本的 dgraph 数据库。

是否有任何脚本或 docker 可以即时安装它。

从日志中我可以看到它无法连接到 Dgraph。那是因为 docker 暴露了端口8088，而 Gru 服务器期望 Dgraph 在8080. 你可以像这样运行 Dgraph

docker run -it -p 127.0.0.1:8080:8080  -v ~/dgraph:/dgraph dgraph/dgraph:v0.7.5 dgraph --bindall=true

您还必须运行自述文件中提到的 Gru 服务器和 caddy。现在我想了想，UI 不需要与 Gru Web 服务器分开运行。我可以尝试在周末添加一步快速安装指南。
