HI,

I have a task that runs only on servers that are under Kafka group. How can i run the task on Kafka and Webserver groups only.

Thanks

- name: install java-8-openjdk' packages
  yum:
    name: ['java-1.8.0-openjdk']
    state: latest
    when: "'kafka' in group_names"

This is one option I have used in the past

I have a partial success that I can not figure what is the problem.
I have 2 tasks, one not in group and the other in group

The first task is running as required, the second task is skipping all groups - Can not understand why

- name: install java-11-openjdk' packages
  yum:
    name: ['java-11-openjdk']
    state: latest
  when:
    - inventory_hostname not in groups.kafka
    - inventory_hostname not in groups.kafka_master

- name: install java-8-openjdk' packages
  yum:
    name: ['java-1.8.0-openjdk']
    state: latest
  when:
    - inventory_hostname in groups.kafka
    - inventory_hostname in groups.kafka_master

- name: install java-11-openjdk' packages
  yum:
    name: ['java-11-openjdk']
    state: latest
  when:
    - inventory_hostname not in groups.kafka
    - inventory_hostname not in groups.kafka_master

- name: install java-8-openjdk' packages
  yum:
    name: ['java-1.8.0-openjdk']
    state: latest
  when:
    - inventory_hostname in groups.kafka
    - inventory_hostname in groups.kafka_master

That is because both conditions are combined with an AND, so I can't be true.

You can try or (untested):

when: inventory_hostname in groups.kafka or inventory_hostname in groups.kafka_master
