无法连接到http://localhost:8080/tcpSlaveAgentListener/:连接被拒绝(连接被拒绝)
提问于 2021-01-11 00:41:48
我使用docker容器运行Jenkins，并使用以下命令在localhost:8080上访问它：
sudo docker run --name uditgauravtest11 -p 8085:8080 -v /var/run/docker.sock:/var/run/docker.sock uditgaurav/test:1现在，我已经在http://localhost:8080访问了Jenkins web UI
我正在使用这个git repo https://github.com/uditgaurav/jenkins-template设置一个管道
在这里，管道使用Kubernetes YAML作为作业的一部分运行，我为该作业配置了一个单独的GKE集群，并使用Manage Jenkins > Manage Node and Cloud > Configure Jenkins将其连接到Jenkins
现在，当我触发Jenkins Job时，它会在GKE集群上启动一个从pod，其中有两个容器，一个运行jenkins/inbound-agent:4.3-4镜像的jnlp容器，另一个我在Git repo pod-delete.yml (https://github.com/uditgaurav/jenkins-template)中提到的容器。
但jnlp容器在进入运行状态后立即进入失败状态，并出现以下错误，pod被终止，一个新的pod出现。
命令：
# "docker-test-68-xwmvf-b6w6f-fmpd2" is the slave pod created on the cluster
kubectl logs -f docker-test-68-xwmvf-b6w6f-fmpd2 -c jnlp错误：

对此有什么帮助吗？如果我需要分享更多的信息，请告诉我。

错误:严重:无法连接到http://localhost:8080/tcpSlaveAgentListener/：连接被拒绝(连接被拒绝)
首先，确保您的GKE集群可以连接到Jenkins主机的50000 TCP端口。(telnet 12.12.12.12 50000)
您的代理无法连接到Jenkins master，如果它们不在同一主机上，您需要设置"Jenkins URL“(管理Jenkins >管理节点和云>配置Jenkins -> Kubernetes)，如"http://12.12.12.12:8080”
