title: ansible parse json with several keys with the same name to one list variable
body: <p>I have an issue to parse a json using ansible
  I have a task that connected to rancher and get a json file</p>
  
  <p>task:</p>
  
  <pre><code>- uri:
      url: http://rancher.local:8080/v1/hosts
      method: GET
      user: ##################
      password: ################
      body_format: json
    register: hosts_json
  
  - name: test
    set_fact:
      rancher_env_hosts: "{{ item.hostname }}"
    #when: item.hostname == "*-i-*"
    with_items: "{{hosts_json.json.data}}"
  
  - name: output
    debug:
      msg: "hosts: {{rancher_env_hosts}}"
  </code></pre>
  
  <p>and I get the following json (after edit it to be more readable):</p>
  
  <pre><code>{
      "json": {
          "data": [
              {
                  "hostname": "rancher-i-host-02",
                  "id": "adsfsa"
              },
              {
                  "hostname": "rancher-i-host-01",
                  "id": "gfdgfdg"
              },
              {
                  "hostname": "rancher-q-host-01",
                  "id": "dfgdg"
              },
              {
                  "hostname": "rancher-q-host-02",
                  "id": "dfgdg"
              }
          ]
  
      }
  
  }
  </code></pre>
  
  <p>When I start the playbook I get only the last host name in the variable and not all the list of hostname. can I register all the list to the same variable?</p>
  
  <p>In addition, I also added a line with the a comment "#" in order to get only the host names that match the string "-i-" bit it's not working. any idea?</p>
