Hello,

We have configured a kubernetes cloud in our jenkins with our kubernetes aws server. And we have a sharedlib to create dynamic agents to build, deploy, quality audit, run integration tests and tnr tests, deploy on ec2, deploy on kubernetes, etc.

This agent is formed with differents container according to the type of projects and the goal of the pipeline. But the agent contains always a jnlp container using the official image inbound-agent-4.7-1.

The problem is that sometimes (not systematic) the agent fail to be created. In the namespace I have a pod created but not already running and in my jenkins pipeline I have this error:

[Pipeline] Start of Pipeline[Pipeline] libraryResource[Pipeline] libraryResource[Pipeline] libraryResource[Pipeline] libraryResource[Pipeline] libraryResource[Pipeline] libraryResource[Pipeline] echo[WARNING] label option is deprecated. To use a static pod template, use the 'inheritFrom' option.[Pipeline] podTemplate[Pipeline] {[Pipeline] nodeCreated Pod: kubernetes-npr fr-jenkins-npr/phoxy-74-kd5b5-58gg1Still waiting to schedule task
