[ansible-devel] Check existence of a value from dictionary with list

[rijeshpp]

Hello all,

I have to implement a logic where I need to create a few secrets in 
kubernetes cluster using ansible. The login I am trying to implement is to 
get registered all the secrets in a namepsapce first, then create the 
secrets if that not present. I specifically want to know how I can validate 
the secret already present. 

- name: Get all insights secrets in namespace '{{ 
ansible_operator_meta.namespace }}'
  community.kubernetes.k8s_info:
    api_version: "v1"
    kind: "secrets"
    namespace: "{{ ansible_operator_meta.namespace }}"
    label_selectors: 
      - project=myproject
  register: secrets_register
 when: debug is not defined

This will register all the secrets with specific label from the namespace. 
This will be dictionary with lists as given below. 

secrets_register:
        resources:
          - apiVersion: v1
            data:
              
_DATA_ENCRYPTION_PASSWORD:VTJGc2RHVmtYMS82b2EyOW9CZXNBY3lWTmI4QzBEclZKaW40U2haQ3hTMGl6bUxXMmFmamVVMXNPRC9kQ05kcA==
            kind: Secret
            metadata:
              labels:
              name: data-encryption-password
              namespace: test
          - apiVersion: v1
            data:
              
_DATA_ADMIN:VTJGc2RHVmtYMS82b2EyOW9CZXNBY3lWTmI4QzBEclZKaW40U2haQ3hTMGl6bUxXMmFmamVVMXNPRC9kQ05kcA==
            kind: Secret
            metadata:
              labels:
              name: mongodb-authsecret
              namespace: test
          - apiVersion: v1
            data:
              
_DATA_TEST:VTJGc2RHVmtYMS82b2EyOW9CZXNBY3lWTmI4QzBEclZKaW40U2haQ3hTMGl6bUxXMmFmamVVMXNPRC9kQ05kcA==
            kind: Secret
            metadata:
              labels:
              name: ingressca
              namespace: test

And then I need to create secrets with a logic when secret_name not in 
secrets_register.resources[*].metadata.name is in secrets_register 
something like below. 

- name: Create secret
  k8s:
      state: present
      definition: 
        apiVersion: v1
        kind: Secret
        type: Opaque             
        metadata:
          name: "{{ secret_name }}"
          namespace: "{{ project_name | lower }}"     
        data:
          config_data.json: "{{ lookup('template', 
mongo_conn_templates_path + '/config_data.json' ) | tojson | b64encode }}"
  when: >
    debug is not defined
    and secret_name not in secrets_register.resources[*].metadata.name is 
in secrets_register

But unfortunately I can't get this statement "secret_name not in 
secrets_register.resources[*].metadata.name is in" working as I am not able 
to figure out how to check existence of a value in a dictionary of lists in 
ansible. Can someone help?

Thanks in advance,
Rijesh.
