Below is my JSON file:
[
{
"?xml": {
"attributes": {
"encoding": "UTF-8",
"version": "1.0"
}
}
},
{
"domain": [
{
"name": "mydom"
},
{
"domain-version": "12.2.1.3.0"
},
{
"server": [
{
"name": "AdminServer"
},
{
"ssl": {
"name": "AdminServer"
}
},
{
"listen_port": "12400"
},
{
"listen_address": "mydom.host1.bank.com"
}
]
},
{
"server": [
{
"name": "myserv1"
},
{
"ssl": [
{
"name": "myserv1"
},
{
"login-timeout-millis": "25000"
}
]
},
{
"listen_port": "22421"
}
]
}
]
}
]
Here is the code to get the listen port number form the json
---
- name: ReadJsonfile
hosts: localhost
tasks:
- name: Display the JSON file content
shell: "cat this.json"
register: result
- name: save the Json data to a Variable as a Fact
set_fact:
jsondata: "{{ result.stdout | from_json }}"
- name: create YML for server name with Listen port
shell: "echo {{ server.0.name }}_httpport: {{ httpport[0].listen_port }}>>{{ playbook_dir }}/wlsdatadump.yml"
loop: "{{ jsondata[1].domain }}"
vars:
server: "{{ item.server | selectattr('name', 'defined') }}"
httpport: "{{ item.server | selectattr('listen_port', 'defined') | list }}"
when: item.server is defined and (item.server | selectattr('listen_port', 'defined')) != []
I get the below error when executing the play
TASK [create YML for server name with Listen port] ************************************************************
skipping: [localhost] => (item={'name': 'mydom'})
skipping: [localhost] => (item={'domain-version': '12.2.1.3.0'})

If i change the port number from numeric to non-numeric say change "12400" to "portfirst" the playbook works fine.
This issue may have to do with the data type.
Can you please suggest how can i overcome this error?
CodePudding user response:
you create a file listenport.j2
in folder templates
:
{% for item in jsondata[1].domain if item.server is defined and (item.server | selectattr('listen_port', 'defined')) != [] %}
{{ item.server.0.name }}_httpport: {{ (item.server | selectattr('listen_port', 'defined')| list).0.listen_port }}
{% endfor %}
playbook:
- name: ReadJsonfile
hosts: localhost
tasks:
- name: Display the JSON file content
shell: "cat ./file2.json"
register: result
- name: save the Json data to a Variable as a Fact
set_fact:
jsondata: "{{ result.stdout | from_json }}"
- name: template
template:
src: listenport.j2
dest: "{{ playbook_dir }}/wlsdatadump.yml"
result in file wlsdatadump.yml:
AdminServer_httpport: 12400
myserv1_httpport: 22421
if you are working on lot of hosts (not only on localhost) and just want to create the file on localhost, use delegate_to: localhost inside the task
