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

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 ```auto - 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 ``` ```auto ``` TASK [install java-11-openjdk’ packages] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ok: [10.201.51.34] skipping: [10.201.51.39] skipping: [10.201.51.40] skipping: [10.201.51.41] ok: [10.201.51.38] ok: [10.201.51.37] ok: [10.201.51.42] ok: [10.201.51.36] skipping: [10.201.51.44] skipping: [10.201.51.45] skipping: [10.201.51.46] ok: [10.201.51.30] ok: [10.201.51.31] ok: [10.201.51.35] ok: [10.201.51.32] ok: [10.201.51.33] ok: [10.201.51.5] TASK [install java-8-openjdk’ packages] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* skipping: [10.201.51.42] skipping: [10.201.51.34] skipping: [10.201.51.36] skipping: [10.201.51.37] skipping: [10.201.51.38] skipping: [10.201.51.39] skipping: [10.201.51.40] skipping: [10.201.51.41] skipping: [10.201.51.30] skipping: [10.201.51.31] skipping: [10.201.51.32] skipping: [10.201.51.44] skipping: [10.201.51.45] skipping: [10.201.51.46] skipping: [10.201.51.5] skipping: [10.201.51.35] skipping: [10.201.51.33] ---

You can try or (untested): when: inventory\_hostname in groups.kafka or inventory\_hostname in groups.kafka\_master Regards         Racke
