Pod creation fails when merging the configuration

Issue

  • After upgrading to version 2.176.1.4 the creation of pods fails.
  • Issue can have two aspects:
    1. An issue when merging two pod templates yaml fields.
      If a parent pod template has an incorrect yaml field, you would see an error. This is because the yaml fields of the parent pods were ignored before and they are now merged in the definition.
    2. An issue when merging two pod templates environment variables:
java.lang.IllegalStateException: Duplicate key EnvVar(name=JAVA_TOOL_OPTIONS, value=-Xmx1g, valueFrom=null, additionalProperties={})
