Setting Docker Agent template gets NullPointerException

See original GitHub issue

When defining a Docker Agent template in my config file I get a java.lang.NullPointerException.

This is my jenkins.ymlconfig file:

jenkins:
  clouds:
    - docker:
        name: "gce-docker"
        dockerApi:
          dockerHost:
            uri: "tcp://172.17.0.1:2375"
        templates:
        - dockerTemplateBase:
            image: "jenkins-agent-android-a4f8224:latest"
          labelString: "android gce daemon"
          name: "android"
          pullStrategy: PULL_NEVER

When removing the templates heading, everything works fine. Is there any solution for this problem?

Environment: Jenkins version: 2.164.3 CasC Plugin version: 1.15 Docker plugin: 1.1.6 OS: Jenkins docker image (jenkins/jenkins:lts)

And this is the Java error I get:

So, after adding connector: attach the previous Java exception is gone. 😄

This config is working:

jenkins:
  clouds:
    - docker:
        name: "gce-docker"
        dockerApi:
          dockerHost:
            uri: "tcp://172.17.0.1:2375"
        templates:
        - connector: attach
          dockerTemplateBase:
            image: "jenkins-agent-android-a4f8224:latest"
          name: "android"
          pullStrategy: PULL_NEVER
          removeVolumes: true
