Automating Elastic Agent Policies

Elastic Stack Elastic Agent
1

I have been experimenting with attempting to automate the ECK elastic agent policy in fleet. Currently, my fleet server set up is this with these two policies defined:

apiVersion: kibana.k8s.elastic.co/v1
kind: Kibana
metadata:
  name: ${kibana_name}
spec:
  version: 8.4.1
  count: 1
  elasticsearchRef:
    name: eck-elasticsearch-cluster
  config:
    xpack.fleet.agents.fleet_server.hosts: "${fleet_server_urls}"
    xpack.fleet.agents.elasticsearch.hosts: "${fleet_elasticsearch_urls}"
    xpack.fleet.agents.pollingRequestTimeout: 30000
    xpack.fleet.packages:
      - name: system
        version: latest
      - name: elastic_agent
        version: latest
      - name: fleet_server
        version: latest
      - name: kubernetes
        version: 1.19.1
      - name: journald
        version: 1.1.0
    xpack.fleet.agentPolicies:
      - name: Fleet Server on ECK policy
        id: eck-fleet-server
        namespace: default
        is_managed: false
        is_default: false
        is_default_fleet_server: true
        unenroll_timeout: 200
        package_policies:
        - name: fleet_server_1
          id: fleet_server_1
          package:
            name: fleet_server
      - name: Elastic Agent on ECK policy
        id: eck-agent
        namespace: default
        monitoring_enabled:
          - logs
          - metrics
        unenroll_timeout: 200
        is_default: true
        package_policies:
          - name: journald-1
            id: journald-1
            package:
              name: journald
          - name: kubernetes-1
            id: kubernetes-1
            package:
              name: kubernetes

Now, once this is created. We go into the UI, and update the kubernetes integration under this ECK Elastic Policy to only pull k8s container logs:

Now, I want to automate this by adding it into my yaml. so I thought I could view the yaml for the Elasticsearch policy, and add the inputs under the package field in my original yaml aboce. Here is the elastic agent policy yaml I can pull from the UI once I manually edited it to my liking:

Unfortunately, this does not work when pushing the changes through the operator. What am I doing wrong?
