Question

我刚刚在Azure门户网站中创建了一个帐户，并按照说明在此处创建了我的第一个图表数据库表单：https://docs.microsoft.com/en-us/azure/cosmos-db/create-graph-gremlin-console

我从Apache Thinkerpop网站下载了Gremlin Console v3.3.0，并根据文档更新了remote-secure.yaml。但是，每次我尝试连接时，都要调用以下命令

:remote connect tinkerpop.server conf/remote-secure.yaml

Gremlin控制台返回

然后我想我可能是我的配置并从门户网站快速入门创建了一个Persons示例项目。配置看起来像这样：

hosts: [myGraph.graphs.azure.com]
port: 443
username: /dbs/graphdb/colls/Persons
password: myPrimaryKey
connectionPool: {
  enableSsl: true}
serializer: { className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV1d0, config: { serializeResultToString: true }}

除了username值包含不同的db和collection名称之外，它与我的原始配置基本相同。但是，当我在控制台中连接到远程时，它会返回相同的错误。

我认为它可能是门户网站上的防火墙，但它目前已关闭。

如果重要，我的操作系统是macOS。

Answer 1

将您的终端更改为xxxx.gremlin.cosmosdb.azure.com，然后尝试。

Answer 2

我遇到了完全相同的问题，@Lukas的回答为我解决了这个问题。

这是我的配置文件的内容：

# Connect securely to remote Cosmos DB via Gremlin API
# Use .gremlin.cosmosdb.azure.com to avoid infinite stack trace
hosts:
  - <account-name>.gremlin.cosmosdb.azure.com
port: 443
# Find your database name and collection ID in the Azure portal
username: /dbs/<db>/colls/<coll>
# Pick read-write or read-only key
password: <key from Cosmos DB account>
connectionPool:
  enableSsl: true
  # Add cert file to avoid this error:
  # WARN  org.apache.tinkerpop.gremlin.driver.Cluster  - SSL configured without a trustCertChainFile and thus trusts all certificates without verification (not suitable for production)
  trustCertChainFile: /etc/ssl/certs/Baltimore_CyberTrust_Root.pem
serializer:
  className: org.apache.tinkerpop.gremlin.driver.ser.GraphSONMessageSerializerV1d0
  config:
    serializeResultToString: true

此外，我正在使用此Docker映像启动Gremlin控制台：cruftlab/gremlin-console（其中包含connectionPool.trustCertChainFile中使用的证书）。

我创建了两个文件夹：gremlin-data/{conf,data}，并将配置（我上面粘贴的一个）存储在gremlin-data/conf/cosmosdb.yaml中。然后，我使用以下命令启动Gremlin控制台：

docker run --rm -it \
  -v $(pwd)/gremlin-data/conf:/opt/gremlin/conf/extra \
  -v $(pwd)/gremlin-data/data:/opt/gremlin/data \
  cruftlab/gremlin-console

现在，已加载的配置文件应该可以在映像中访问（在conf/extra下）。因此，现在您应该可以通过运行以下命令（在Gremlin控制台中）连接到Cosmos DB：

gremlin> :remote connect tinkerpop.server conf/extra/cosmosdb.yaml
==>Configured <account-name>.gremlin.cosmosdb.azure.com/<ip address>:443
gremlin>

然后就可以了！

此外，您应该能够在Cosmos DB和data卷之间进行导入/导出，但是到目前为止，我仅在本地进行了测试。：）

积分：

gremlin控制台到azure-cosmosdb 404
