Question

我安装了 dgraph gru 用于面试

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

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。

Answer 1

从日志中我可以看到它无法连接到 Dgraph。那是因为 docker 公开端口 8088 而 Gru 服务器期望 Dgraph 在 8080 上运行。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 Gru 服务器和 caddy，如 README 中所述。现在我想到了，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。
