Editing a yaml file with cpu

playbook.yml

# This file will handle all the paychex specific edits to openshift config files
# # This file updates the following information
# # turns on emptydir quotas on compute nodes
- hosts: nodes

  tasks:
    - name: Update Compute Node EmptyDir quota settings
      lineinfile: dest=/etc/origin/node/node-config.yaml
                backup="yes"
                regexp='^    perFSGroup:'
                state=present
                line="    perFSGroup{{ ":" }} 2Gi"
      register: nodeConfig
      when:
        - openshift_node_labels is defined
        - openshift_node_labels.type  == 'compute'

    - name: Update compute and Infrastructure node system reservations step1
      lineinfile: dest=/etc/origin/node/node-config.yaml
                backup="yes"
                insertafter='kubeletArguments:'
                line={{item}}
      with_items:
## this is what is giving me issues
## what I want is the 4 lines below added after "kubletArguments:" 
### kube-reserved:
###    - "cpu=150m,memory=1G"
###  system-reserved:
###    - "cpu=150m,memory=1G"
        - 'kube-reserved{{ ":" }} "cpu=150m,memory=1G"'
        - 'system-reserved{{ ":" }} "cpu=150m,memory=1G"'
      register: nodeConfig

Maybe try to use blockinfile like this:

blockinfile: 
  dest:         /etc/origin/node/node-config.yaml
  backup:       'yes'
  insertafter:  'kubeletArguments:'
  block: |
    kube-reserved:
      - "cpu={{ cpu }},memory={{ ram }}"
    system-reserved:
      - "cpu={{ cpu }},memory={{ ram }}"
  register:     nodeConfig

@m0nkey-br4in thanks, unfortunately we are running v1.9 of ansible, and blockinfile is not available.
