In Jenkins master, Configure Global Security -> Agent -> TCP port for inbound agents, the default value is 50000. Try to curl the 50000 port too for example: # curl http://xxxx:50000 Jenkins-Agent-Protocols: JNLP4-connect, Ping Jenkins-Version: 2.176.4 Jenkins-Session: c0470948 Client: 10.0.181.80 Server: 10.0.78.182 Remoting-Minimum-Version: 3.4 On Thu, Feb 6, 2020 at 9:09 AM adrian lee <[email protected]> wrote: > I ran a pod in my cluster exec the pod and ping my jenkins with no issue. > > > On Thu, Feb 6, 2020 at 1:24 PM Liejun Tao <[email protected]> wrote: > >> Suggest to run a test pod from your cluster and check network >> connectivity to your jenkins, >> http://ec2-18-140-64-62.ap-southeast-1.compute.amazonaws.com:8080/ >> <http://ec2-18-140-64-62.ap-southeast-1.compute.amazonaws.com:8080/tcpSlaveAgentListener/> >> >> On Wed, Feb 5, 2020 at 7:57 PM adrian lee <[email protected]> wrote: >> >>> >>> >>> On Thursday, February 6, 2020 at 9:53:53 AM UTC+8, adrian lee wrote: >>>> >>>> Hi all >>>> >>>> I am trying to use jenkins and kubernetes plugin.
