      Hi everyone, apologize first for any information leak or mis-understanding, this is my first time to report issue in community. And I have toke merely all way I can to deal with it.



      jenkins 2.176.3 with all plugins in latest version
      java version (both jenkins master and spot fleet) 1.8.0
      – plugins –
      ec2-fleet-plugin 1.10.2
      git-client 2.8.2
      junit 1.28

      Jenkins master on ec2 r5.large, Amazon linux
      Spot fleet on r4.large / r5.large / r5.xlarge , Amazon linux



      I use jenkins with spot-fleet plugin for CI

      CI all pass in spot-fleet with initial ec2 mechine

      While ec2 scale out, CI fail in new instance with "remote call on  i-xxxxxx failed"

      Below is the log from instance of spot-fleet (retrieved from ${jenkinsHome/remoting/logs})




      3 CI job with identical codebase run at the same time
      a ec2-spot-fleet with init 2 instance

      In my case, 1 CI job take 2 ec2 instance, so one job will take the initial two instance, and the other jobs have to run in scaled out instances.

      • Result : CI pass in one job and fail in other two

      [More information]

      1. Below is the jenkinsfile with sensitive information replaced


      2. I face the problem in two scenario, because docker build and testing in different spot fleet

      scenario A:  

      building spot-fleet rotate ec2 every day, new ec2 instance fail to build 

      scenario B:

      is the reproduce experiment, happen in spot-fleet used in testing stage
      new ec2 (scaled out) fail in CI testing while initial instances success
      you can see pipeline with blueOcean in ec2_N_success/fail.png attachment
