Jenkins while trying to execute job on docker cloud node: ‘/’ is an unsafe character

Jenkins keeps creating/removing docker containers and increasing provisioning number in Cloud Statistics every X seconds, where X is the timeout option for your docker agent template in your docker cloud, while trying to execute job.

I have only one docker cloud defined with instance capacity of 3.

Job execution status will remain "Waiting for next available executor" during this time if no other nodes/clouds are defined with available executors.

Name parameter of docker agent template in docker cloud contained '/' in my case and removing it from the name solved the issue and job executed successfully.
