HI , I have my inventory file like below , where I am using the variables primaryNode, secondaryNode in the roles so that particular role will run on the host specified infront of ansible\_host values. Now, how can i pass multiple hosts in the inventory under secondaryNode so that role2 will run on all those nodes one by one. and I will not need to create role3 or role 4 for those. inventory file > all: > children: > ha: > hosts: > primaryNode: > ansible\_host: domain.net1 > secondaryNode: > ansible\_host: domain.net2 my yaml looks liike elow : [2](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L2)[3](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L3)[4](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L4)[5](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L5)[6](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L6)[7](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L7)[8](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L8)[9](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L9)[10](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L10)[11](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L11)[12](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L12)[13](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L13)[14](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L14)[15](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L15)[16](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L16)[17](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L17)[18](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L18)[19](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L19)[20](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L20)[21](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L21)[22](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L22)[23](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L23)[24](https://gitlab.dev.f1.novartis.net/f1-devops-platform/platform-automation/blob/FOR-1307/ansible-playbooks/artifactory_install.yml#L24) ```auto ---- name: Installing primary node hosts: primaryNode become: True roles: - role: role1 - name: Installing secondary node hosts: secondaryNode become: True roles: - role: role2 ``` ---

I think its not possible to pass multiple values to “ansible\_host” variable . You can create “group” in inventory file with all the hosts listed under it. Thanks Neha Pithadiya. ---

Not sure if it's possible with ansbile but with Salt you can set Grains and do if else statements based on those grains {% if role[host1] } - role: host1 {% elif role[hoat2] %} -role: host 2 {%endif%} I would look up condition s for ansible ---

Don't know about virtual grains, but you can apply when: conditions - role: role1   when: "'role1' in group\_names" Regards        Racke
