【中文标题】在 Service Fabric 中运行 Azure DevOps 自托管生成代理时出现“无法解析远程名称”【英文标题】:"The remote name could not be resolved" when running an Azure DevOps self-hosted build agent in Service Fabric 【发布时间】:2021-04-06 07:45:35 【问题描述】:按照这篇文章,我可以在我的 Windows 10 机器上成功启动自托管代理:
https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/docker?view=azure-devops#windows
但是,当我尝试使用 Windows Server 20H2 节点在 Service Fabric 中启动相同的 Docker 映像时,我得到了以下容器日志条目:

我也试过没有这些规格:
ServicePackageResourceGovernancePolicy 资源治理政策 健康配置我想知道是否可以在没有 HTTP 或 TCP 端点的情况下在 Service Fabric 中启动一个容器。
编辑:
另一个观察结果:当我通过 SSH/远程连接到我将映像部署到的节点之一和 docker run -it
直接映像时,可以解析远程名称并且安装过程有效(?)。所以它接缝 SF 以不同的方式启动容器。
编辑 2:
尝试使用简化的start.ps1
Invoke-WebRequest -OutFile dotnet.zip https://dotnetcli.blob.core.windows.net/dotnet/Sdk/2.2.402/dotnet-sdk-2.2.402-win-x64.zip
Read-Host
带来同样的错误。比较 SF 控制容器和直接启动容器上的 docker inspect
,我发现可能相关的偏差:

【问题讨论】:
根据这个文档docs.microsoft.com/en-us/azure/service-fabric/…,本地单节点Service Fabric集群不支持容器,你有这种情况吗? 谢谢——不,我部署到常规的 3 节点 TEST 集群 如果你创建一个简单的 docker 容器,你能重现这个问题吗? @CeceDong-MSFT 我添加了一个具有相同结果的简单测试 - 再次在同一节点上本地运行 docker run 成功执行脚本 使用 open 或 nat 有区别吗? docs.microsoft.com/en-us/azure/service-fabric/… nslookup 也有不同的结果吗? 【参考方案1】:当使用 compose 部署 部署相同的映像时,网络分辨率工作正常,并且构建代理已安装并成功启动。
比较清单我添加了端点并且它正在工作:
