How merge yaml in podTemplate?

I have the following code in groovy:

void call(Closure closure) {
    pod_template_maven_image = ...
    pod_template_maven_m2 = ...
    pod_template_nodejs_image = ...
    pod_template_sonar_image = ...
    toleration_condition = true

    def yaml_config = ""
    if(toleration_condition){
        yaml_config = """
        spec:
          tolerations:
          - key: "my_toleration"
            operator: "Equal"
            value: "value1"
            effect: "NoSchedule"
        """
    }

    podTemplate(containers: ..., 
    volumes: ..., 
    etc..., 
    yaml: yaml_config, 
    yamlMergeStrategy: merge()) {
        node(POD_LABEL) {
            closure()
        }
    }
}

At the moment, when I run the job in jenking nothing happens, the pod is created whitout error. But the yaml is not added in pod.

We want to add the toleration (yaml_config) in podTemplate depending of toleration_condition value.

I'm new in this area and don't now if is possible. Its is? Whats the best way to do it?

Thanks.

The problem was solved by placing the complete manifest structure, which ended up being automatically merged.

It took less than a year to find out.

Tip: I see you use the Kubernetes plugin. Have you seen the section of inheritance? Using the declarative pipeline syntax, with inheritFrom, might provide a much cleaner way to achieve the wanted results. Here we also keep the yamlMergeStrategy as default (override()).

I have seen that the indents of the "delta yaml" (yaml_config), provided to yaml:, influences the final outcome (trailing and starting newlines could also have impact). So I would recommend testing with a yaml_config like:

    yaml_config = """
spec:
  tolerations:
  - key: "my_toleration"
    operator: "Equal"
    value: "value1"
    effect: "NoSchedule" """
